I read an article a couple of weeks back about an Open Source Bionic Leg, which was reporting on research began as a NSF funded project at the University of Michigan (UoM), with collaboration from Northwestern, University of Texas at Dallas and CMU. UofM has a website that provides everything you need to build your own open source leg (OSL) leg at OpenSourceLeg.com.
The challenge in human prosthetics these days is that all research is done in silos. Much of it is proprietary and only available within corporations but even university research has been hampered by the lack of a standard platform that could be used to develop new components and ideas on.
The real difficulty is defining the control logic (code). The OSL project is intended to resolve this lack of a platform by providing everything a researcher (hobbyist, or amputee) needs to build their own, at home or in the lab.
The website includes a parts lists and STEP files as well as an estimated cost ($28.5K) to build your own powered prosthetic leg. They also have a Excel spread sheet with all the parts listed, including part numbers and links to where they can be ordered (McMaster-Carr, SolidWorks, & Dephy)
They also show how to build a leg with a short youtube videoof how to assemble the whole leg as well as details for each subassembly with separate how-to videos for each.
The open source leg makes use of code from FlexSEA (Flexible Scaleable Electronics Architecture) andDephy. FlexSea was originally developed by Jean-Francois (JF) Duval while he was at MIT for his doctoral thesis. He has since joined Dephy a robotics design firm. The open source leg project uses FlexSea/Dephy code for its servo control mechanisms.
There is a GitHub Python, MatLab and C control library repo with all the code. The open source leg website also includes instructions, scripts and an image file which can be used to build your own RaspberryPi (4) controller for the leg.
The two (ankle and knee) servos are USB connected to the RPi. There are also other sensors such as the joint (servo-motor) encoders and a six axis load sensor I2C connected to the RPi. Each servo has its own 950mAh battery.
On the OSL website’s control page one can see these servos in action (with short youtube segments). They also provide instructions on how to use the open source control library to take the servo mechanisms through their paces.
Although on the OSL website’s control page I didn’t see anything which put the whole leg together to make use of it in a real world application. They did show on the Data page a youtube video with the OSL attached to a person and being used to walk up and down stairs, inclines and walking across a floor.
Seeing as how the OSL website included STEP and PDF files for all the (machined) parts which represent $15.6K of the $28.5K, if one really wanted to do this on the cheap, one could just 3D print these parts in plastic. It would obviously not suffice mechanically for real use, but it could provide a platform for testing and developing control logic. At some point one could upgrade some or all of the plastic 3D printed parts to something more durable for use in human trials.
Another option is to purchase multiple sets of parts. The OSL website also showed price estimates for purchasing two sets of ankle and knee parts. But I’d imagine if one was so inclined, a number of researchers (hobbyists or amputees) could get together and order multiple sets of parts for reduced prices.
It’s also possible, with a lot of work, that the open source leg could be redesigned to support an open source arm-hand mechanism. This is where having 3D printed plastic parts could be extremely useful in helping to redesign the leg into an arm-hand.
Read an article a couple of weeks back (An internet of tires?… IEEE Spectrum) and can’t seem to get it out of my head. Pirelli, a European tire manufacturer was demonstrating a smart tire or as they call it, their new Cyber Tyre.
The Cyber Tyre includes accelerometer(s) in its rubber, that can be used to sense the pavement/road surface conditions. Cyber Tyre can communicate surface conditions to the car and using the car’s 5G, to other cars (of same make) to tell them of problems with surface adhesion (hydroplaning, ice, other traction issues).
Presumably the accelerometers in the Cyber Tyre measure acceleration changes of individual tires as they rotate. Any rapid acceleration change, could potentially be used to determine whether the car has lost traction due and why.
They tested the new tires out at a (1/3rd mile) test track on top of a Fiat factory, using Audi A8 automobiles and 5G. Unclear why this had to wait for 5G but it’s possible that using 5G, the Cyber Tyre and the car could possibly log and transmit such information back to the manufacturer of the car or tire.
Accelerometers have become dirt cheap over the last decade as smart phones have taken off. So, it was only a matter of time before they found use in new and interesting applications and the Cyber Tyre is just the latest.
Internet of Vehicles
Presumably the car, with Cyber Tyres on it, communicates road hazard information to other cars using 5G and vehicle to vehicle (V2V) communication protocols or perhaps to municipal or state authorities. This way highway signage could display hazardous conditions ahead.
Audi has a website devoted to Car to X communications which has embedded certain Audi vehicles (A4, A5 & Q7), with cellular communications, cameras and other sensors used to identify (recognize) signage, hazards, and other information and communicate this data to other Audi vehicles. This way owning an Audi, would plug you into this information flow.
Pirelli’s Cyber Car Concept
Prior to the Cyber Tyre, Pirelli introduced a Cyber Car concept that is supposedly rolling out this year. This version has tyres with real time pressure, temperature, (static) vertical load and a Tyre ID. Pirelli has been working with car manufacturers to roll out Cyber Car functionality.
The Tyre ID seems to be a file that can include anything that the tyre or automobile manufacturer wants. It sort of reminds me of a blockchain data blocks that could be used to validate tyre manufacturing provenance.
The vertical load sensor seems more important to car and tire manufacturers than consumers. But for electrical car owners, knowing car weight could help determine current battery load and thereby more precisely know how much charge is left in a battery.
Pirelli uses a proprietary algorithm to determine tread wear. This makes use of the other tyre sensors to predict wear and perhaps uses an AI DL algorithm to do this.
ABS has been around for decades now and tire pressure sensors for over 10 years or so. My latest car has enough sensors to pretty much drive itself on the highway but not quite park itself as of yet. So it was only a matter of time before something like smart tires would show up.
But given their integration with car electronics systems, it would seem that this would only make sense for new cars that included a full set of Cyber Tyres. That is until all tire AND car manufacturers agreed to come up with a standard protocol to communicate such information. When that happens, consumers could chose any tire manufacturer and obtain have similar if not the same functionality from them.
I suppose someone had to be first to identify just what could be done with the electronics available today. Pirelli just happens to be it for now in the tire industry.
I just don’t want to have to upgrade tires every 24 months. And, if I have to wait a long time for my car to boot up and establish communications with my tires, I may just take a (dumb) bike.
Recall that in part 1, we discussed most of the threats posed by clouds to both hardware and software IT vendors. In that post we talked about some of the more common ways that vendors are trying to head off this threat (for now).
In this post we want to talk about some uncommon ways to deal with the coming cloud apocalypse.
But first just to put the cloud threat in perspective, the IT TAM is estimated, by one major consulting firm, to be a ~$3.8T in 2019 with a growth rate of 3.7% Y/Y. The same number for public cloud spending, is ~$214B in 2019, growing by 17.5% Y/Y. If both growth rates continue (a BIG if), public cloud services spend will constitute all (~98.7%) of IT TAM in ~24 years from now. No nobody would predict those growth rates will continue but it’s pretty evident the growth trends are going the wrong way for (non-public cloud) IT vendors.
There are probably an infinite number of ways to deal with the cloud. But outside of the common ones we discussed in part 1, only a dozen or so seem feasible to me and even less are fairly viable for present IT vendors.
Move to the edge and IoT.
Make data center as easy and cheap to use as the cloud
Focus on low-latency, high data throughput, and high performing work and applications
Move 100% into services
Move into robotics
The edge has legs
Probably the first one we should point out would be to start selling hardware and software to support the edge. Speaking in financial terms, the IoT/Edge market is estimated to be $754B in 2019, and growing by over a 15.4% CAGR ).
So we are talking about serious money. At the moment the edge is a very diverse environment from cameras, sensors and moveable devices. And everybody seems to be in the act, big industrial firms, small startups and everyone in between. Given this diversity it’s hard to see that IT vendors could make a decent return here. But given its great diversity, one could say it’s ripe for consolidation.
And the edge could use some reference architectures where there are devices at the extreme edge, concentrators at the edge, more higher concentrators at nodes and more at the core, etc. So there’s a look and feel to it that seems like Ro/Bo – central core hub and spoke architectures, only on steroids with leaf proliferation that can’t be stopped. And all that data coming in has to be classified, acted upon and understood.
There are plenty of other big industrial suppliers in this IoT/edge field but none seem to have the IT end of the market that Hitachi Vantara can claim to. Some sort of combination of a large IT vendor and a large industrial firm could potentially do the same
However, Hitachi Vantara seems to be focusing on the software side of the edge. This may be an artifact of Hitachi family of companies dynamics. But it seems to be leaving some potential sales on the table.
Hitachi Vantara has the advantage of being into industrial technology in a big way so the products they create operate in factories, rail yards, ship yards and other industrial sites around the world already. So, adding IoT and edge capabilities to their portfolio is a natural extension of this expertise.
There are a few vendors going into the Edge/IoT in a small way, but no one vendor personifies this approach more than Hitachi Vantara. The Hitachi family of companies has a long and varied history in OT (operational technology) or industrial technology. And over the last many years, HDS and now Hitachi Vantara, have been pivoting their organization to focus more on IoT and edge solutions and seem to have made IOT, OT and the edge, a central part of their overall strategy.
So there’s plenty of money to be made with IoT/Edge hardware and software, one just has to go after it in a big way and there’s lots of competition. But all the competition seems to be on the same playing field (unlike the public cloud playing field).
Getting to “data center as a cloud”
There are a number of reasons why customers migrate work to the cloud, ease of use, ease of storage, ease of scale, access to myriad applications, access to multi-regional data centers, CAPex financial model, to name just a few.
There’s nothing that says much of this couldn’t be provided at the data center. It’s mostly just a lot of open source software and a lot of common hardware. IT vendors can do this sort of work if they put their vast resources to go after it.
From the pure software side, there are a couple of companies trying to do this namely VMware and Nutanix but (IBM) RedHat, (Dell) Pivotal, HPE Simplivity and others are also going after this approach.
Hardware wise CI and HCI, seem to be rudimentary steps towards common hardware that’s easy to deploy, operate and support. But these baby steps aren’t enough. And delivery to deployment in weeks is never going to get them there. If Amazon can deliver books, mattresses, bicycles, etc in a couple of days. IT vendors should be able to do the same with some select set of common hardware and have it automatically deployable in seconds to minutes once powered on.
And operating these systems has to be drastically simplified. On any public cloud there’s really no tuning required, almost minimal configuration, and then it’s just load your data and go. Yes there’s a market place to select, (virtual) hardware, (virtual) storage hardware, (virtual) networking hardware, (virtual server) O/S and (virtual?) open source applications.
Yes there’s a lots of software behind all that virtualization. And it’s fundamentally different than today’s virtualized systems. It’s made to operate only on commodity hardware and only with open source software.
The CAPex financial model is less of a problem. Today. I find many vendors are offering their hardware (and some software) on a CAPex, pay as you go model. More of this needs to be made available but the IT vendors see this, and are already aggressively moving in this direction.
The clouds are not standing still what with Azure Stack, AWS and GCP all starting to provideversions of their stack on prem in the enterprise. This looks to be a strategic battleground between the clouds and IT vendors.
Making everything IT can do in the cloud available in the data center, with common hardware and software and with the speed and ease of deployment, operations and support (maintenance) should be on every IT vendors to do list.
Unfortunately, this is not going to stop the public cloud completely, but it has the potential to slow the growth rate. But time is short, momentum has moved to the public cloud and I don’t (yet) see the urgency of the IT vendors to make this transition happen today.
Focus on low-latency, high data throughput and high performance work
This is somewhat unfair as all the IT vendors are already involved in these markets in a big way. But, there are some trends here, that indicate this low-latency market will be even more important over time.
For example, more and more of commercial IT is starting to take advantage of big data and AI to profit from all their data. And big science is starting to migrate to IT, where massive data flows and data analysis tools are becoming important to the data center. If anything, the emergence of IoT and the edge will increase data flows that need to be analyzed, understood, and ultimately dealt with.
DNA genomics may be relegated to big pharma/medical but 3D visualization is becoming so mainstream that I can do it on my desktop. These sorts of things were relegated to HPC/big science just a decade or so ago. What tools exist in HPC today that the IT data center of the future will deam a necessary part of their application workload.
Is this a sizable TAM, probably not today. In all honesty it’s buried somewhere in the IT TAM above. But it can be a growing niche, where IT vendors can stake a defensive position and the cloud may have a tough time dislodging.
I say the cloud “may have trouble dislodging” because nothing says that the entire data flow/work flow couldn’t migrate to the cloud, if the responsiveness was available there. But, if anything (guaranteed) responsiveness is one of the few achilles heels of the public cloud. Security may be the other one.
We see IBM, Intel, and a few others taking this space seriously. But all IT vendors need to see where they can do better here.
Focus on services
This not really out-of-box thinking. Some (old) IT vendors have been moving into services for over 50 years now others are just seeing there’s money to be made here. Just about every IT vendor has deployment & support services. most hardware have break-fix services.
But standalone IT services are more specialized and in the coming cloud apocalypse, services will revolve around implementing cloud applications and functionality or migrating work from the cloud or (rarely in the future) back to on prem.
So services are already a significant portion of IT spend today. And will probably not be impacted by the move to the cloud. I’d say that because implementing applications and services will still exist as long as the cloud exists. Yes it may get simpler (better frameworks, containerization, systemization), but it won’t ever go away completely.
Robots, the endgame
Ok laugh now. I understand this is a big ask to think that Robot spending could supplement and maybe someday surpass IT spending. But we all have to think long term. What is a self driving car but a robotic data center on wheels, generating TB of data every day it’s driven.
Robots over the next century will invade every space, become ever present and ever necessary to modern world functioning . They will have sophisticated onboard computing, motors, servos, sensors and on board and backend processing requirements. The real low-latency workload of the future will be in the (computing) minds of robots.
Even if the data center moves entirely to the cloud, all robotic computation will never reside there because A) it’s too real time and B) it needs to operate well even disconnected from the Internet.
Is all this going to happen in the next 10 or 20 years, maybe not but 30 to 50 years out this world will have a multitude of robots operating within it. .
Who’s going to develop, manufacture, support and sustain these mobile computing data centers on wheels, legs, slithering and flying bodies?
I would say IT vendors of today are uniquely positioned to dominate this market. Here to the industry is very fragmented today. There are a few industrial robotic companies and just about every major auto manufacturer is going after self driving cars. And there are many bit players today. So it’s ripe for disruption and consolidation. .
Yet, none of the major IT vendors seem to be going after this. Ok Amazon (hardware & software) and Microsoft (software) have done work in this arena. If anything this should tell IT vendors that they need to start working here as well.
But alas, none have taken up the mantle. In the mean time robot startups are biting the dust left and right, trying to gain market traction.
That seems to be about it for the major viable out of the box approaches to the public cloud threat. I have a few other ideas but none seem as useful as the above.
I’ve been writing about neuromorphic chips since 2011, 8 long years (see IBM SyNAPSE chip post from 2011 or search my site for “neuromorphic”) and none have been successfully reached the market. The problems with neurmorphic architectures have always been twofold, scaling AND software.
Scaling up neurons
The human brain has ~86B neurons (see wikipedia human brain article). So, 8 million neuromorphic neurons is great, but it’s about 10K X too few. And that doesn’t count the connections between neurons. Some human neurons have over 1000 connections between nerve cells (can’t seem to find this reference anymore?).
To get from a single chip with 125K neurons to their 8M neuron system, Intel took 64 chips and put them on a couple of boards. To scale that to 86B or so would take ~690, 000 of their neuromorphic chips. Now, no one can say if there’s not some level below 85B neuromorphic neurons, that could support a useful AI solution, but the scaling problem still exists.
Then there’s the synapse connections between neuromorphic neurons problem. The article says that Loihi chips are connected in a heirarchical routing network, which implies to me that there are switches and master switches (and maybe a really big master switch) in their 8M neuromorphic neuron system. Adding another 4 orders of magnitude more neuromorphic neurons to this may be impossible or at least may require another 4 sets of progressively larger switches to be added to their interconnect network. There’s a question of how many hops and the resultant latency in connecting two neuromorphic neurons together but that seems to be the least of the problem with neuromorphic architectures.
Missing software abstractions
The first time I heard about neuromorphic chips I asked what the software looks like and the only thing I heard was that it was complex and not very user friendly and they didn’t want to talk about it.
I keep asking about software for neuromorphic chips and still haven’t gotten a decent answer. So, what’s the problem. In today’s day and age, software is easy to do, relatively inexpensive to produce and can range from spaghetti code to a hierarchical masterpieces, so there’s plenty of room to innovate here.
But whenever I talk to engineers about what the software looks like, it almost seems like a software version of an early plug board unit-record computer (essentially card sorters). Only instead of wires, you have software neuromorphic network connections and instead of electro-magnetic devices, one has software spiking neuromorphic neuron hardware.
The way we left plugboards behind was by building up hardware abstractions such as adders, shifters, multipliers, etc. and moving away from punch cards as a storage medium. Somewhere along this transition, we created programing languages like (macro) Assemblers, COBOL, FORTRAN, LISP, etc. It’s the software languages that brought computing out of the labs and into the market.
It’s been at least 8 years now, and yet, no-one has built a spiking neuromorphic computer language yet. Why not?
I think the problem is there’s no level of abstraction above a neuron. Where’s the aritmetic logic unit (ALU) or register equivalents in neuromorphic computers? They don’t exist as far as I can see.
Until we can come up with some higher levels of abstraction, coding neuromorphic chips is going to be an engineering problem not a commercial endeavor.
But neuromorphism has advantages
The IEEE article states a couple of advantages for neuromorphic computing: less energy to perform inferencing (and possibly training) and the ability to train on incremental data rather than having to train across whole datasets again.
And the incremental training issue doesn’t seem any easier when you have ~80B neurons, with an occasional 1000s of connections between them to adjust correctly. From my perspective, its training advantage seems illusory at best.
Another advantage of neuromorphism is that it simulates the real analog logic of a human brain. Again, that’s great but a brain takes ~22 years to train (college level). Maybe because neuromorphic chips are electronic perhaps training can be done 100 times faster. But there’s still the software issue
I hate to be the bearer of bad news. There’s been some major R&D spend on neuromorphism and it continues today with no abatement.
I just think we’d all be better served figuring out how to program the beast than on –spending more to develop more chip hardware..
This is hard for me to say, as I have always been a proponent of hardware innovation. It’s just that neuromorphic software tools don’t exist yet. And I’m afraid, I don’t see any easy way forward to make any progress on this.
I was on a vendor call last week and they were discussing their recent technological advances in quantum computing. During the discussion they mentioned a number of ways to code for quantum computers. The currently most popular one is based on the QIS (Quantum Information Software) Kit.
Instead there is a paper, on the Open Quantum Assembly Language (QASM) that describes the Quantum computational environment and coding language used in QIS Kit.
It appears that quantum computers can be considered a special computational co-proccesor engine, operated in parallel with normal digital computation. This co-processor happens to provide a quantum simulation.
One programs a quantum computer by creating a digital program which describes a quantum circuit that uses qubits and quantum registers to perform some algorithm on those circuits. The quantum circuit can be measured to provide a result which more digital code can interpret and potentially use to create other quantum circuits in a sort of loop.
There are four phases during the processing of a QIS Kit quantum algorithm.
QASM compilation which occurs solely on a digital computer. QASM source code describing the quantum circuit together with compile time parameters are translated into a quantum PLUS digital intermediate representation.
Circuit generation, which also occurs on a digital computer with access to the quantum co-processor. The intermediate language compiled above is combined with other parameters (available from the quantum computer environment) and together these are translated into specific quantum building blocks (circuits) and some classical digital code needed and used during quantum circuit execution.
Execution, which takes place solely on the quantum computer. The system takes as input, the collection of quantum circuits defined above and runtime control parameters,and transforms these using a high-level quantum computer controller into low-level, real time instructions for the quantum computer building the quantum circuits. These are then executed and the results of the quantum circuit(s) execution creates a result stream (measurements) that can be passed back to the digital program for further processing
Post-Processing, which takes place on a digital computer and uses the results from the quantum circuit(s) execution and other intermediate results and processes these to either generate follow-on quantum circuits or output ae final result for the quantum algorithm.
As qubit coherence only last for a short while, so results from one execution of a quantum circuit cannot be passed directly to another execution of quantum circuits. Thus these results have to be passed through some digital computations before they can be used in subsequent quantum circuits. A qubit is a quantum bit.
Quantum circuits don’t offer any branching as such.
The only storage for QASM are classical (digital) registers (creg) and quantum registers (qreg) which are an array of bits and qubits respectively.
There are limited number of built-in quantum operations that can be performed on qregs and qubits. One described in the QASM paper noted above is the CNOT operation, which flips a qubit, i.e., CNOT alb will flip a qubit in b, iff a corresponding qubit in a is on.
Quantum circuits are made up of one or more gate(s). Gates are invoked with a set of variable parameter names and quantum arguments (qargs). QASM gates can be construed as macros that are expanded at runtime. Gates are essentially lists of unitary quantum subroutines (other gate invocations), builtin quantum functions or barrier statements that are executed in sequence and operate on the input quantum argument (qargs) used in the gate invocation.
Opaque gates are quantum gates whose circuits (code) have yet to be defined. Opaque gates have a physical implementation may yet be possible but whose definition is undefined. Essentially these operate as place holders to be defined in a subsequent circuit execution or perhaps something the quantum circuit creates in real time depending on gate execution (not really sure how this would work).
In addition to builtin quantum operations, there are other statements like the measure or reset statement.The reset statement sets a qubit or qreg qubits to 0. The measure statement copies the state of a qubit or qreg into a digital bit or creg (digital register).
There is one conditional command in QASM, the If statement. The if statement can compare a creg against an integer and if equal execute a quantum operation. There is one “decision” creg, used as an integer. By using IF statements one can essentially construct a case statement in normal coding logic to execute quantum (circuits) blocks.
Quantum logic within a gate can be optimized during the compilation phase so that they may not be executed (e.g., if the same operation occurs twice in a gate, normally the 2nd execution would be optimized out) unless a barrier statement is encountered which prevents optimization.
Quantum computer cloud
In 2016, IBM started offering quantum computers in its BlueMix cloud through the IBM Quantum (Q) Experience. The IBM Q Experience currently allows researchers access to 5- and 16-qubit quantum computers.
There are three pools of quantum computers: 1 pool called IBMQX5, consists of 8 16-qubit computers and 2 pools of 5 5-qubit computers, IBMQX2 and IBMQX4. As I’m writing this, IBMQX5 and IBMQX2 are offline for maintenance but IBMQX4 is active.
Google has recently released the OpenFermion as open source, which is another software development kit for quantum computation (will review this in another post). Although Google also seems to have quantum computers and has provided researchers access to them, I couldn’t find much documentation on their quantum computers.
Two other companies are working on quantum computation: D-Wave Systems and Rigetti Computing. Rigetti has their Forest 1.0 quantum computing full stack programming and execution environment but I couldn’t easily find anything on D-Wave Systems programming environment.
Last month, IBM announced they have constructed a 50-Qubit quantum computer prototype.
IBM has also released 20-Qubit quantum computers for customer use and plans to offer the new 50-Qubit computers to customers in the future.
Last week WDC announced their next generation technology for hard drives, MAMR or Microwave Assisted Magnetic Recording. This is in contrast to HAMR, Heat (laser) Assisted Magnetic Recording. Both techniques add energy so that data can be written as smaller bits on a track.
The problem with PMR-SMR-TDMR is that the max achievable disk density is starting to flat line and approaching the “WriteAbility limit” of the head-media combination.
That is even with TDMR, SMR and PMR heads, the highest density that can be achieved is ~1.1Tb/sq.in. The Writeability limit for the current PMR head-media technology is ~1.4Tb/sq.in. As a result most disk density increases over the past years has been accomplished by adding platters-heads to hard drives.
MAMR and HAMR both seem able to get disk drives to >4.0Tb/sq.in. densities by adding energy to the magnetic recording process, which allows the drive to record more data in the same (grain) area.
There are two factors which drive disk drive density (Tb/sq.in.): Bits per inch (BPI) and Tracks per inch (TPI). Both SMR and TDMR were techniques to add more TPI.
I believe MAMR and HAMR increase BPI beyond whats available today by writing data on smaller magnetic grain sizes (pitch in chart) and thus more bits in the same area. At 7nm grain sizes or below PMR becomes unstable, but HAMR and MAMR can record on grain sizes of 4.5nm which would equate to >4.5Tb/sq.in.
It turns out that HAMR as it uses heat to add energy, heats the media drives to much higher temperatures than what’s normal for a disk drive, something like 400C-700C. Normal operating temperatures for disk drives is ~50C. HAMR heat levels will play havoc with drive reliability. The view from WDC is that HAMR has 100X worse reliability than MAMR.
In order to generate that much heat, HAMR needs a laser to expose the area to be written. Of course the laser has to be in the head to be effective. Having to add a laser and optics will increase the cost of the head, increase the steps to manufacture the head, and require new suppliers/sourcing organizations to supply the componentry.
HAMR also requires a different media substrate. Unclear why, but HAMR seems to require a glass substrate, the magnetic media (many layers) is deposited ontop of the glass substrate. This requires a new media manufacturing line, probably new suppliers and getting glass to disk drive (flatness-bumpiness, rotational integrity, vibrational integrity) specifications will take time.
Probably more than a half dozen more issues with having laser light inside a hard disk drive but suffice it to say that HAMR was going to be a very difficult transition to perform right and continue to provide today’s drive reliability levels.
MAMR uses microwaves to add energy to the spot being recorded. The microwaves are generated by a Spin Torque Oscilator, (STO), which is a solid state device, compatible with CMOS fabrication techniques. This means that the MAMR head assembly (PMR & STO) can be fabricated on current head lines and within current head mechanisms.
MAMR doesn’t add heat to the recording area, it uses microwaves to add energy. As such, there’s no temperature change in MAMR recording which means the reliability of MAMR disk drives should be about the same as todays disk drives.
MAMR uses todays aluminum substrates. So, current media manufacturing lines and suppliers can be used and media specifications shouldn’t have to change much (?) to support MAMR.
MAMR has just about the same max recording density as HAMR, so there’s no other benefit to going to HAMR, if MAMR works as expected.
WDC’s technology timeline
WDC says they will have sample MAMR drives out next year and production drives out in 2019. They also predict an enterprise 40TB MAMR drive by 2025. They have high confidence in this schedule because MAMR’s compatabilitiy with current drive media and head manufacturing processes.
WDC discussed their IP position on HAMR and MAMR. They have 400+ issued HAMR patents with another 100+ pending and 75 issued MAMR patents with 46 more pending. Quantity doesn’t necessarily equate to quality, but their current IP position on both MAMR and HAMR looks solid.
WDC believes that by 2020, ~90% of enterprise data will be stored on hard drives. However, this is predicated on achieving a continuing, 10X cost differential between disk drives and (QLC 3D) flash.
It was the worst of times. The industry changes had been gathering for a decade almost and by this time were starting to hurt.
The cloud was taking over all new business and some of the old. Flash’s performance was making high performance easy and reducing storage requirements commensurately. Software defined was displacing low and midrange storage, which was fine for margins but injurious to revenues.
Both companies had user events in Vegas the last month, NetApp Insight 2017 last week and Hitachi NEXT2017 conference two weeks ago.
As both companies respond to industry trends, they provide an interesting comparison to watch companies in transition.
NetApp’s underlying theme is to change the world with data and they want to change to help companies do this.
Vantara’s philosophy is data and processing is ultimately moving into the Internet of things (IoT) and they want to be wherever the data takes them.
Hitachi Vantara is a brand new company that combines Hitachi Data Systems, Hitachi Insight Group and Pentaho (an analytics acquisition) into one organization to go after the IoT market. Pentaho will continue as a separate brand/subsidiary, but HDS and Insight Group cease to exist as separate companies/subsidiaries and are now inside Vantara.
NetApp sees transitions occurring in the way IT conducts business but ultimately, a continuing and ongoing role for IT. NetApp’s ultimate role is as a data service provider to IT.
Vantara believes the main customer issue is the need to digitize the business. Because competition is emerging everywhere, the only way for a company to succeed against this interminable onslaught is to digitize everything. That is digitize your manufacturing/service production, sales, marketing, maintenance, any and all customer touch points, across your whole value chain and do it as rapidly as possible. If you don’t your competition will.
NetApp sees customers today have three potential concerns: 1) how to modernize current infrastructure; 2) how to take advantage of (hybrid) cloud; and 3) how to build out the next generation data center. Modernization is needed to free capital and expense from traditional IT for use in Hybrid cloud and next generation data centers. Most organizations have all three going on concurrently.
Vantara sees the threat of startups, regional operators and more advanced digitized competitors as existential for today’s companies. The only way to keep your business alive under these onslaughts is to optimize your value delivery. And to do that, you have to digitize every step in that path.
NetApp views the threat to IT as originating from LoB/shadow IT originating applications born and grown in the cloud or other groups creating next gen applications using capabilities outside of IT.
NetApp is looking mostly towards the cloud. At their conference they announced a new Azure NFS service powered by NetApp. They already had Cloud ONTAP and NPS, both current cloud offerings, a software defined storage in the cloud and a co-lo hardware offering directly attached to public cloud (Azure & AWS), respectively.
Vantara is looking towards IoT. At their conference they announced Lumada 2.0, an Industrial IoT (IIoT) product framework using plenty of Hitachi software functionality and intended to bring data and analytics under one software umbrella.
NetApp is following a path laid down years past when they devised the data fabric. Now, they are integrating and implementing data fabric across their whole product line. With the ultimate goal that wherever your data goes, the data fabric will be there to help you with it.
Vantara is broadening their focus, from IT products and solutions to IoT. It’s not so much an abandoning present day IT, as looking forward to the day where present day IT is just one cog in an ever expanding, completely integrated digital entity which the new organization becomes.
They both had other announcements, NetApp announced ONTAP 9.3, Active IQ (AI applied to predictive service) and FlexPod SF ([H]CI with SolidFire storage) and Vantara announced a new IoT turnkey appliance running Lumada and a smart data center (IoT) solution.
They both are.
Digitization is the future, the sooner organizations realize and embrace this, the better for their long term health. Digitization will happen with or without organizations and when it does, it will result in a significant re-ordering of today’s competitive landscape. IoT is one component of organizational digitization, specifically outside of IT data centers, but using IT resources.
In the mean time, IT must become more effective and efficient. This means it has to modernize to free up resources to support (hybrid) cloud applications and supply the infrastructure needed for next gen applications.
One could argue that Vantara is positioning themselves for the long term and NetApp is positioning themselves for the short term. But that denies the possibility that IT will have a role in digitization. In the end both are correct and both can succeed if they deliver on their promise.
Read an article the other week in MIT news on how Proximity boosts collaboration on MIT campus. Using MIT patents and papers published between 2004-2014, researchers determined how collaboration varied based on proximity or physical distance.
What they found was that distance matters. The closer you are to a person the more likely you are collaborate with him or her (on papers and patents at least).
The two sets of charts below show the buildings where research (papers and patents) was generated. Building heterogeneity, crowdedness (lab space/researcher) and number of papers and patents per building is displayed using the color of the building.
The number of papers and patents per building is self evident.
The heterogeneity of a building is a function of the number of different departments that use the building. The crowdedness of a building is an indication of how much lab space per faculty member a building has. So the more crowded buildings are lighter in color and less crowded buildings are darker in color.
I would like to point out Building 32. It seems to have a high heterogeneity, moderate crowdedness and a high paper production but a relatively low patent production. Conversely, Building 68 has a low heterogeneity, low crowdedness and a high production of papers and a relatively low production of patents. So similar results have been obtained from buildings that have different crowdedness and different heterogeneity.
The paper specifically cites buildings 3 & 32 as being most diverse on campus and as “hubs on campus” for research activity. The paper states that these buildings were outliers in research production on a per person basis.
And yet there’s no global correlation between heterogeneity or crowdedness for that matter and (paper/patent) research production. I view crowdedness as a substitute for researcher proximity. That is the more crowded a building is the closer researchers should be. Such buildings should theoretically be hotbeds of collaboration. But it doesn’t seem like they have any more papers than non-crowded buildings.
Also heterogeneity is often cited as a generator of research. Steven Johnson’s Where Good Ideas Come From, frequently mentions that good research often derives from collaboration outside your area of speciality. And yet, high heterogeneity buildings don’t seem to have a high production of research, at least for patents.
So I am perplexed and unsatisfied with the research. Yes proximity leads to more collaboration but it doesn’t necessarily lead to more papers or patents. The paper shows other information on the number of papers and patents by discipline which may be confounding results in this regard.
Telecommuting and productivity
So what does this tell us about the plight of telecommuters in todays business and R&D environments. While the paper has shown that collaboration goes down as a function of distance, it doesn’t show that an increase in collaboration leads to more research or productivity.
This last chart from the paper shows how collaboration on papers is trending down and on patents is trending up. For both papers and patents, inter-departmental collaboration is more important than inter-building collaboration. Indeed, the sidebars seem to show that the MIT faculty participation in papers and patents is flat over the whole time period even though the number of authors (for papers) and inventors (for patents) is going up.
So, I, as a one person company can be considered an extreme telecommuter for any organization I work with. I am often concerned that my lack of proximity to others adversely limits my productivity. Thankfully the research is inconclusive at best on this and if anything tells me that this is not a significant factor in research productivity
And yet, many companies (Yahoo, IBM, and others) have recently instituted policies restricting telecommuting because, they believe, it reduces productivity. This research does not show that.
So IBM and Yahoo I think what you are doing to concentrate your employee population and reduce or outright eliminate telecommuting is wrong.
