GreyBeards talk with Lee Caswell and Dave Wright of NetApp

In our 30th episode, we talk with Dave Wright (@JungleDave), SolidFire founder, VP & GM SolidFire of NetApp and Lee Casswell (@LeeCaswell), VP Products, Solution & Services Marketing NetApp. Dave’s been on before as CEO of SolidFire back in May of 2014, but this is the first time for Lee. Dave’s also been a prominent guest at Storage Field Day, most recently at SFD9 with Dave Hitz from NetApp. Unclear how Lee managed to avoid TFD/SFD duty but it’s only a matter of time.

Solidfire was recently acquired by NetApp in their largest acquisition ever, signaling a new direction for them (acquisition closed 2 Feb. 2016). Since we had spent a prior podcast on another recent storage acquisition, we thought it only appropriate to talk with these two as well. We started the discussion with Dave and how it feels to be within the NetApp umbrella.

Another topic that came up was how flash gets used in the cloud. Old school had it that flash was just high IO performance but nowadays, next gen application development has a range of IO requirements which all need consistent performance to data. Flash with scale out and QoS can handle this wide range of requirements across cloud applications. Lee mentioned how flash adoption is changing from application specific to more general purpose storage which is removing the “IO bottleneck”.

Google had written a study saying that for the next decade there will not be a flash-disk crossover but the differences are small enough that you almost have to be hyper-scale customers to see significant economic advantages.

We discussed the lack of lot’s of AFA’s doing well on throughput intensive benchmarks. Dave mentioned that throughput was one of disk’s better performing modes and in the past, storage interfaces 3Gbps-6Gbps hid a lot of flash performance. But benchmarks of synthesized pure workloads aren’t real world, workloads in real data centers are much messier.

IO density (IOPS/GB) came up as another discussion topic.  At low IO density, disk may still make sense but as IO density increases, all flash makes much more sense.

Google also mentioned the importance of tail-end IO latency (IO latency at 99.9%). Poor tail IO latency has been an ongoing problem holding back the adoption of hybrid storage. All flash has same advantages here but are not all AFAs are immune to the problems in tail-end latency.

The podcast runs just over 39 minutes and episode covers a lot of ground about their products, flash technology advantages, and market dynamics.  Listen to the podcast to learn more.

Greybeards talk car videos, storage and IT trends with Marc Farley

In our 30th episode, we talk with 3rd time guest star,  Marc Farley (@GoFarley), Formerly with Datera and Tegile. Marc has recently gone on sabbatical and we wanted to talk to him about what was keeping him busy and what was going on in storage/IT industry these days.

Marc is currently curating a car comedy vlog called theridecast.com. Apparently people, at least in California, are making comedy videos in their cars. They can be quite hilarious, checkout this episode of comedian in cars getting coffee.

While in the storage biz, the industry is getting battered by a number of trends: IT shrinking budgets, vendor proliferation, migration to cloud, and flash becoming old hat. Marc makes multiple points as to why the storage market is undergoing such a major transition these days:

  • Death to tech refresh, long live the cloud –  yes the cloud does upgrade hardware but  planned storage system obsolesce doesn’t happen in the cloud anymore. Cloud providers are  buying new SSDs, disks, white box servers, memory etc,  but not enterprise class storage, server or networking hardware.
  • AFA is boring, but selling – every vendor’s got one , two or sometimes three and they all know how to provide flash storage services. Customers pay extra for AFA, whether they need to or not, because they are swapping out old expensive, enterprise class storage for AFAs that often cost less but still provide better performance..
  • Tail IO latency becoming more important but it’s not understood – when IO response times go from 100µsec to 10msec, it hurts. It doesn’t matter if it’s every 1000 or 10,000 IOs, customers want less performance variability, which is a main reason they move to AFA in the first place. But not all AFA’s perform the same in tail latency and SSD controller/system architecture make a big difference.
  • Hybrid storage survives but only if you go big – hybrid storage economics makes sense only for large, diverse data repositories, that mix user directories, non-performance sensitive apps, and other structured and unstructured data in one data store.
  • Greenfield apps & secondary storage are moving to the cloud but migrating current apps to the cloud is difficult –  for new app development and archive storage, moving to or starting in the cloud is a no-brainer. Transitioning running enterprise class apps to the cloud is tough to do, that requires multiple skill sets and may never be successful. Hybrid  (cloud-on premises) enterprise class apps are too arduous to even contemplate.
  • Realtime analytics is emerging but data needs to be on flash – yes MapReduce is a batch activity which can uses lots of slow disk but there’s more to analytics than MR, and doing log analysis, in anything approaching realtime, one needs flash performance.
  • Optical’s persistence is great but who leaves data on the same technology for  20 years –  with magnetic and electronic storage densities going up every couple of years, who could afford keep data on the same optical technology that was 20 years old. Imagine using microfiche to keep PB of data today, inconceivable.

As for IT in general, one limiter of IT activity will become the lack of skilled engineers, specifically full-stack engineers and data scientists.

We ended our discussions on the economics of Samsung 3D NAND and Intel-Micron (IM) 3D Xpoint non-volatile memories. Both new semiconductor technologies are always long term investments. Today, Samsung is probably losing money on each 3D TLC NAND SSD it sells, but over time, as  fab yields improve, it should become cheap enough to make a profit. Similarly, 3D Xpoint may be costly to produce early on, but as IM perfect  their fab processes, the technology should become inexpensive enough to make oodles of $s for them. And there’s more technology changes to come.

The podcast runs just over 40 minutes and covers a lot of ground. Marc’s been in the IT almost as long as the GreyBeards and has a unique perspective on what’s happening today, having been with so many diverse, major and (minor) startup vendors throughout his tenure in the industry.  Listen to the podcast to learn more.

GreyBeards talk with Pivot3 and NexGen Storage about their recent acquisition announcement

In our 29th episode, we talk with John Spiers (@lefthandsan), Co-founder & CEO of NexGen Storage and Ron Nash (@hronaldnash), Chairman & CEO of Pivot3, a hyper converged infrastructure provider.  We have talked with John before (see last June’s podcast episode) about NexGen Storage technology. Recently, Pivot3 announced they were going to acquire NexGen Storage and Howard and I wanted to talk about to them what brought the two together.

We have discussed hyper converged solutions before (see ScaleComputing and Gridstore podcasts) dating all the way to the first GreyBeardsOnStorage podcast with Nutanix but this is the first time we have talked with Pivot3 and Ron Nash. As discussed in those podcasts hyper converged infrastructure (HCI) brings together compute, storage and sometimes networking under one overarching infrastructure framework and delivers all this as a single solution that customers can then tailor to their own needs. In a typical HCI solution, storage is software defined, compute is under the control of a hypervisor and can include software defined networking.

Sometime last fall both John and Ron were considering additional funding opportunities with their VC’s, when one of them, Brian Smith of S3 Ventures, suggested they look at combining their two operations into one company.

It seemed that John was looking to expand their sales and marketing team to take NexGen Storage to the next level while Ron was looking for some additional differentiation in storage technology that could take their solution beyond where they were today. It seemed to Mr. Smith that each of them had just what the other one was looking for.

As GreyBeardsOnStorage listeners should recall, NexGen Storage is known for their hybrid storage solution with fine grained QoS capabilities. Although, NexGen Storage is delivered as an appliance, their main IP is in storage software and so implementing a Software Defined Storage solution under HCI was certainly an option.

Pivot3 has been around since 2002 and has sale teams around the world with an extensive marketing team. Pivot3 uses Zen and now mostly VMware for their hypervisor environments and typically run on whitebox servers with storage bridge bay boxes running software defined storage. Pivot3 had already implemented scaleable erasure coding which is something NexGen Storage was also looking at.

Pivot3 and the rest of the HC solutions market space seems split into two. That is there is a good market at the low end, where small companies, remote offices, small workgroups, etc. are looking for an easy to deploy, full IT stack solution. And at the high end, large web properties and other IT behemoths  also need an easy to deploy, readily automated solution, that can scale to whatever size they require.

Both Pivot3 and NexGen Storage work well in VDI deployments but NexGen was mostly deployed in currently running VDI environments, whereas Pivot3 primarily went into brand new deployments, that could take advantage of HCI solutions.

In the podcast we discuss some of these large organizations such as Google, Facebook, Etrades and others and what they are looking for in an IT infrastructure. We also discuss some of the technology trends that are impacting both HCI and storage infrastructure. It turns out NexGen’s extensive QoS capabilities are what can make HCI deployments work even better than they do today.

In the past couple of days, the technology teams of the two companies have been hot and heavy, examining possible synergies and discussing how to reconcile their respective roadmaps. John and Ron were sitting in the back during these discussions throwing out ideas which the technical teams ran with as far as they could.

The podcast runs just over 41 minutes and episode covers a lot of ground about both of their products market spaces, technology, and business dynamics and especially, on how they see the two solutions complementing each other. Apparently the acquisition is on a fast path to close soon. Listen to the podcast to learn more.

GreyBeards on Storage year end 2015 podcast

In our annual yearend podcast and it’s the Ray and Howard show, talking about storage futures, industry trends and some storage world excitement of- the past year.

We start the discussion deconstructing recent reductions in year over year revenues at major storage vendors. It seems with the advent of all flash arrays (AFA), and all major vendors and most startups now have AFAs, customers no longer feel the need to refresh old storage hardware with similarly (over-)configured new systems. Instead, most can get by with AFA storage, at smaller capacities that provides the same, if not better, performance. Further9, the fact that AFAs are available from so many vendors and startups, customers no longer have to buy performance storage exclusively from major vendors anymore. This is leading to a decline in major vendor storage revenues, which should play itself out over the next 1-2 years as most enterprise storage systems are refreshed.

Recent and future acquisitions also came up for discussion. NetApp’s purchase of SolidFire was a surprise, but SolidFire had carved out a good business with service providers and web-scale customers which should broaden NetApp’s portfolio. In the mean time, the Dell-EMC acquisition takes them out of the competition for new technology acquisitions, at least until it closes. NetApp’s new CEO, George Kurian, appears more willing than his predecessor to go after good storage technology, wherever it comes from.

Software delivered (defined) storage came up as well. With the compute available in todays micro-processors, there’s very little a software delivered storage system can’t do. And with scale-out storage, there’s even more cores to work with. Software delivered storage and scale-out will continue to play a spoiler role, at least in the low to mid-range, in the storage market throughout the next year.

Nonetheless, hardware still has some excitement left. Intel’s recent acquisition of Altera, now makes Xeon/x86 processing available for embedded applications that previously had to rely on ARM and MIPS processing. Now, there’s nothing an FPGA hardware based system can’t do. Look for lot’s more activity here over the long term.

We talked about recent SMR disks coming out and how they could be used in storage systems today.  There was some adjacent discussion on the flash-disk crossover, and conclude it’s unlikely over the next 3-5 years, at least for capacity drives. Although there’s plenty of analyst that say it’s already happened, on a pure $/GB there’s still no comparison.

We then turned to  3D TLC NAND and the  reliability capabilities available from current controlller technologies. Raw planar NAND available today is much less reliable than what we had 1-2 generations back, but the drives, if anything, have gotten more reliable. This is due to the reliability technology inherent in todays SSD controllers.

We had an aside, on SSD overprovisioning and how this should become a customer level option.  Reducing overprovisioning would decrease drive endurance but it’s a tradeoff that the vendors/distributors make for customers today. We feel that at least for some customers, they could make this decision just as well. Especially if drive replacements were a customer maintenance activity with replacement SSDs shipped in a just-in-time manner.

We conclude on 3D XPoint (3DX) non-volatile memory. We both agreed 3DX adoption depends on pricing which will change over time. In the long term, we see the potential for a new storage system with 3DX or other new non-volatile memory as a top performing storage/caching/non-volatile memory tier, 3D TLC NAND as a middle tier and SMR disk as the bottom tier. When is another question.

Our year end discussion always wanders a bit, from high end business trends to in the weeds technologies and everything in-between. This one is no exception and runs over 49 minutes. We tried to do another Year End video this time but neither of our video recording systems worked out, but we had a good audio recording, so we went with the podcast this year. Next year should be back to video.  Listen to the podcast to learn more.

GreyBeards talk HPC storage with Molly Rector, CMO & EVP, DDN

oIn our 27th episode we talk with Molly Rector (@MollyRector), CMO & EVP of Product Management/Worldwide Marketing for DDN.  Howard and I have known Molly since her days at Spectra Logic. Molly is also on the BoD of SNIA and Active Archive Alliance (AAA), so she’s very active in the storage industry, on multiple dimensions and a very busy lady.

We (or maybe just I) didn’t know that DDN has a 20 year history in storage and in servicing high performance computing (HPC) customers. It turns out that more enterprise IT organizations are starting to take on workloads that look like HPC activity.

In HPC there are 1000s of compute cores that are crunching on PB of data. For Oil&Gas companies, it’s seismic and wellhead analysis; with bio-informatics it’s genomic/proteomic analysis; and with financial services, it’s economic modeling/backtesting trading strategies. For today’s enterprises such as retailers, it’s customer activity analytics; for manufacturers, it’s machine sensor/log analysis;  and for banks/financial institutions, it’s credit/financial viability assessments. Enterprise IT might not have 1000s of cores at their disposal just yet, but it’s not far off. Molly thinks one way to help enterprise IT is to provide a SuperComputer as a service (ScaaS?) offering, where top 10 supercomputers can be rented out by the hour, sort of like a supercomputing compute/data cloud.

We start early talking about DDN WOS: object store, which can handle archive to cloud or backend tape libraries. Later we discuss DDN ExaScaler and GridScaler, which are NAS appliances for Lustre and massively scale out, parallel file system storage, respectively.

Another key supercomputing storage requirement is  predictable performance. Aside from sophisticated QoS offerings across their products, DDN also offers the IME solution, a bump in the cable, caching system, that can optimize large and small file IO activity for backend DDN NAS scalers. DDN IME is stateless and can be removed from the data path while still allowing IT access  to all their data.

While we were discussing DDN storage interfaces, Molly mentioned they were working on an Omni Path Fabric.  Intel’s new Omni Path Fabric is intended to replace rack scale PCIe networks for HPC.

This months edition is not too technical and runs just over 45 minutes. We only got to SNIA and AAA at the tail end and just for a minute or two. Molly’s always fun to talk to, with enough technical smarts to keep Howard and I at bay, at least for awhile :). Listen to the podcast to learn more.
