69: GreyBeards talk HCI with Lee Caswell, VP Products, Storage & Availability, VMware

Sponsored by:

For this episode we preview VMworld by talking with Lee Caswell (@LeeCaswell), Vice President of Product, Storage and Availability, VMware.

This is the third time Lee’s been on our show, the previous one was back in August of last year. Lee’s been at VMware for a couple of years now and, among other things, is leading the HCI journey at VMware.

The first topic we discussed was VMware’s expanded HCI software defined data center (SDDC) solution, which now includes compute, storage, networking and enhanced operations with alerts/monitoring/automation that ties it all together.

We asked Lee to explain VMware’s SDDC:

  • HCI operates at the edge – with ROBO-2-server environments, VMware’s HCI can be deployed in a closet and remotely operated by a VI from the central site.
  • HCI operates in the data center – with vSphere-vSAN-NSX-vRealize and other software, VMware modernizes data centers for the  pace of digital business..
  • HCI operates in the public Cloud –with VMware Cloud (VMC)  on AWS, IBM Cloud and over 400 service providers, VMware HCI also operates in the public cloud.
  • HCI operates for containers and cloud native apps – with support for containers under vSphere, vSAN and NSX, developers are finding VMware HCI an easy option to run container apps in the data center, at the edge, and in the public cloud.

The importance of the edge will become inescapable, as 50B edge connected devices power IoT by 2020. Lee heard Pat saying compute processing is moving to the edge because of 3 laws:

  1. the law of physics, light/information only travels so fast;
  2. the law of economics, doing all processing at central sites would take too much bandwidth and cost; and
  3. the law(s) of the land, data sovereignty and control is ever more critical in today’s world.

VMware SDDC is a full stack option, that executes just about anywhere the data center wants to go. Howard mentioned one customer he talked with at FMS18, just wanted to take their 16 node VMware HCI rack and clone it forever, to supply infinite infrastructure.

Next, we turned our discussion to Virtual Volumes (VVols). Recently VMware added replication support for VVols. Lee said VMware has an intent to provide a SRM SRA for VVols. But the real question is why hasn’t there been higher field VVol adoption. We concluded it takes time.

VVols wasn’t available in vSphere 5.5 and nowadays, three or more years have to go by before a significant amount of the field moves to a new release. Howard also said early storage systems didn’t implement VVols right. Moreover, VMware vSphere 5.5 is just now (9/16/18) going EoGS.

Lee said 70% of all current vSAN deployments are AFA. With AFA, hand tuning storage performance is no longer something admins need to worry about. It used to be we all spent time defragging/compressing data to squeeze more effective capacity out of storage, but hand capacity optimization like this has become a lost art. Just like capacity, hand tuning AFA performance doesn’t make sense anymore.

We then talked about the coming flash SSD supply glut. Howard sees flash pricing ($/GB) dropping by 40-50%, regardless of interface. This should drive AFA shipments above 70%, as long as the glut continues.

The podcast runs ~21 minutes. Lee’s always great to talk with and is very knowledgeable about the IT industry, HCI in general, and of course, VMware HCI in particular.  Listen to the podcast to learn more.

58: GreyBeards talk HCI with Adam Carter, Chief Architect NetApp Solidfire #NetAppHCI

Sponsored by:In this episode we talk with Adam Carter (@yoadamcarter), Chief Architect, NetApp Solidfire & HCI (Hyper Converged Infrastructure) solutions. Howard talked with Adam at TFD16 and I have known Adam since before the acquisition. Adam did a tour de force session on HCI architectures at TFD16 and we would encourage you to view the video’s of his session.

This is the third time NetApp has been on our show (see our podcast with Lee Caswell and Dave Wright and our podcast with Andy Banta) but this is the first sponsored podcast from NetApp. Adam has been Chief Architect for Solidfire for as long as I have known him.

NetApp has FAS/AFF series storage, E-Series storage and SolidFire storage. Their HCI solution is based on their SolidFire storage system.

NetApp SolidFire HCI Appliance

 

NetApp’s HCI solution is built around a 2U 4-server configuration where 3 of the nodes are actual denser, new SolidFire storage nodes and the 4th node is a VMware ESXi host. That is they have a real, fully functional SolidFile AFA SAN storage system built directly into their HCI solution.

There’s probably a case to be made that this isn’t technically a HCI system from an industry perspective and looks more like a well architected, CI  (converged infrastructure) solution. However, they do support VMs running on their system, its all packaged together as one complete system, and they offer end-to-end (one throat to choke) support, over the complete system.

In addition, they spent a lot of effort improving SolidFire’s, already great VMware software integration to offer a full management stack that fully supports both the vSphere environment and the  embedded SolidFire AFA SAN storage system.

Using a full SolidFire storage system in their solution, NetApp  gave up on the low-end (<$30K-$50K) portion of the HCI market. But to supply the high IO performance, multi-tenancy, and QoS services of current SolidFire storage systems, they felt they had to embed a full SAN storage system.

With other HCI solutions, the storage activity must contend with other VMs and kernel processing on the server. And in these solutions, the storage system doesn’t control CPU/core/thread allocation and as such, can’t guarantee IO service levels that SolidFire is known for.

Also, by configuring their system with a real AFA SAN system, new additional ESXi servers can be added to the complex without needing to purchase additional storage software licenses. Further, customers can add bare metal servers to this environment and there’s still plenty of IO performance to go around. On the other hand, if a customer truly needs more storage performance/capacity, they can always add an additional, standalone SolidFire storage node to the cluster.

The podcast runs ~23 minutes. Adam was very easy to talk with and had deep technical knowledge of their new solution, industry HCI solutions and SolidFire storage.  It’s was a great pleasure for Howard and I to talk with him again. Listen to the podcast to learn more.

55: GreyBeards storage and system yearend review with Ray & Howard

In this episode, the Greybeards discuss the year in systems and storage. This year we kick off the discussion with a long running IT trend which has taken off over the last couple of years. That is, recently the industry has taken to buying pre-built appliances rather than building them from the ground up.

We can see this in all the hyper-converged solutions available  today but it goes even deeper than that. It seems to have started with the trend in organizations to get by with less man-women power.

This led to a desire to purchase pre-buit software applications and now, appliances rather than build from parts. It just takes to long to build and lead architects have better things to do with their time than checking compatibility lists, testing and verifying that hardware works properly with software. The pre-built appliances are good enough and doing it yourself doesn’t really provide that much of an advantage over the pre-built solutions.

Next, we see the coming systems using NVMe over Fabric storage systems as sort of a countertrend to the previous one. Here we see some customers paying well for special purpose hardware with blazing speed that takes time and effort to get working right, but the advantages are significant. Both Howard and I were at the Excelero SFD12 event and it blew us away. Howard also attended the E8 Storage SFD14 event which was another example along a similar vein.

Finally, the last trend we discussed was the rise of 3D TLC and the absence of 3DX and other storage class memory (SCM) technologies to make a dent in the marketplace. 3D TLC NAND is coming out of just about every fab these days and resulting in huge (but costly) SSDs, in the multi-TB range.  Combine these with NVMe interfaces and you have msec access to almost a PB of storage without breaking a sweat.

The missing 3DX SCM tsunami some of us predicted is mainly due to the difficulties in bringing new fab technologies to market. We saw some of this in the stumbling with 3D NAND but the transition to 3DX and other SCM technologies is a much bigger change to new processes and technology. We all believe it will get there someday but for the moment, the industry just needs to wait until the fabs get their yields up.

The podcast runs over 44 minutes. Howard and I could talk for hours on what’s happening in IT today. Listen to the podcast to learn more.

52: GreyBeards talk software defined storage with Kiran Sreenivasamurthy, VP Product Management, Maxta

This month we talk with an old friend from Storage Field Day 7 (videos), Kiran Sreenivasamurthy, VP of Product Management for Maxta. Maxta has a software defined storage solution which currently works on VMware vSphere, Red Hat Virtualization and KVM to supply shared, scale out storage and HCI solutions for enterprises across the world.

Maxta is similar to VMware’s vSAN software defined storage whose licenses can be transferred from one server to another, as you upgrade your data center over time. As software defined storage, Maxta runs on any standard Intel X86 hardware. Indeed, Maxta has one customer running two Super Micro servers and one Cisco server in the same cluster.

Maxta advantages

One item that makes Maxta unique is all of its storage properties are assignable at a VM granularity. That is,  replication, deduplication, compression and even blocksize can all be enabled/set at the VMDK-VM level.  This could be useful for environments supporting diverse applications, such as having a 64K block size for Microsoft Exchange and 4K block size for web servers.

Another advantage is their multi-hypervisor support. Maxta’s support for RH Virtualization, VMware and KVM offers the unique ability to migrate storage and even powered off VMs, from one hypervisor to another. Maxta’s file system is the same for both VMware and KVM clusters.

Maxta clusters

Their software must be licensed on all servers in a vSphere or KVM cluster with access to Maxta storage. The minimum Maxta cluster size is 3 nodes for 2-way replication and 5 nodes for 3-way replication.  Most Maxta systems run on 8 to 12 server node clusters. But Maxta has installations with 20 to 24 nodes in customer deployments.

Maxta supports SSD only as well as SSD-disk hybrid storage. And SSDs can be NVMe as well as SATA SSD storage. In hybrid configurations, Maxta SSDs are used as read and write back caches for disk storage.

Maxta supports compute only nodes, compute-storage nodes and witness only nodes (node with 1 storage device). In addition, besides heterogeneous server support, Maxta clusters can have nodes with different storage capacities. Maxta will optimize VM data placement to balance IO activity across heterogeneous nodes.

Maxta provides a vCenter plugin so VMware admins can manage and monitor their storage inside vSphere environment. Maxta also offers a Cloud Connect MX which is a cloud based system allowing for management of all your Maxta clusters through out an enterprise, wherever they reside.

Even HCI, through partners

For customers wanting an HCI solution, Maxta partners can supply pre-tested, HCI appliances or can configure Maxta software with servers at customer data centers. Maxta has done well OEMing their solution, and one significant success has been their OEM deal with Lenovo in China and East Asia, where they sell HCI appliances with Maxta software.

Maxta has also found success with managed service providers (that want to deploy the software on their own hardware), and SME & ROBO environments. Also Maxta seems to be doing very well in Latin America as well as previously mentioned China.

The podcast runs ~42 minutes. Kiran is knowledgeable individual and has worked with some of the leading storage companies of the last two decades.  Listen to the podcast to learn more.

51: GreyBeards talk hyper convergence with Lee Caswell, VP Product, Storage & Availability BU, VMware

VMware

In this episode we talk with Lee Caswell (@LeeCaswell), Vice President of Product, Storage and Availability Business Unit, VMware.  This is the second time Lee’s been on our show, the previous one back in April of last year when he was with his prior employer. Lee’s been at VMware for a little over a year now and has helped lead some significant changes in their HCI offering, vSAN.

VMware vSAN/HCI business

Many customers struggle to modernize their data centers with funding being the primary issue. This is very similar to what happened in the early 2000s as customers started virtualizing servers and consolidating storage. But today, there’s a new option, server based/software defined storage like VMware’s vSAN, which can be deployed for little expense and grown incrementally as needed. VMware’s vSAN customer base is currently growing by 150% CAGR, and VMware is adding over 100 new vSAN customers a week.

Many companies say they offer HCI, but few have adopted the software-only business model this entails. The transition from a hardware-software, appliance-based business model to a software-only business model is difficult and means a move from a high revenue-lower margin business to a lower revenue-higher margin business. VMware, from its very beginnings, has built a sustainable software-only business model that extends to vSAN today.

The software business model means that VMware can partner easily with a wide variety of server OEM partners to supply vSAN ReadyNodes that are pre-certified and jointly supported in the field. There are currently 14 server partners for vSAN ReadyNodes. In addition, VMware has co-designed the VxRail HCI Appliance with Dell EMC, which adds integrated life-cycle management as well as Dell EMC data protection software licenses.

As a result, customers can adopt vSAN as a build or a buy option for on-prem use and can also leverage vSAN in the cloud from a variety of cloud providers, including AWS very soon. It’s the software-only business model that sets the stage for this common data management across the hybrid cloud.

VMware vSAN software defined storage (SDS)

The advent of Intel Xeon processors and plentiful, relatively cheap SSD storage has made vSAN an easy storage solution for most virtualized data centers today. SSDs removed any performance concerns that customers had with hybrid HCI configurations. And with Intel’s latest Xeon Scalable processors, there’s more than enough power to handle both application compute and storage compute workloads.

From Lee’s perspective, there’s still a place for traditional SAN storage, but he sees it more for cold storage that is scaled independently from servers or for bare metal/non-virtualized storage environments. But for everyone else using virtualized data centers, they really need to give vSAN a look.

Storage vendors shifting sales

It used to be that major storage vendor sales teams would lead with hardware appliance storage solutions and then move to HCI when pushed. The problem was that a typical SAN storage sale takes 9 months to complete and then 3 years of limited additional sales.

To address this, some vendors have taken the approach where they lead with HCI and only move to legacy storage when it’s a better fit. With VMware vSAN, it’s a quicker sales cycle than legacy storage because HCI costs less up front and there’s no need to buy the final storage configuration with the first purchase. VMware vSAN HCI can grow as the customer applications needs dictate, generating additional incremental sales over time.

VMware vSAN in AWS

Recently, VMware has announced VMware Cloud in AWS.What this means is that you can have vSAN storage operating in an AWS cloud just like you would on-prem. In this case, workloads could migrate from cloud to on-prem and back again with almost no changes. How the data gets from on-prem to cloud is another question.

Also the pricing model for VMware Cloud in AWS moves to a consumption based model, where you pay for just what you use on a monthly basis. This way VMware Cloud in AWS and vSAN is billed monthly, consistent with other AWS offerings.

VMware vs. Microsoft on cloud

There’s a subtle difference in how Microsoft and VMware are adopting cloud. VMware came from an infrastructure platform and is now implementing their infrastructure on cloud. Microsoft started as a development platform and is taking their cloud development platform/stack and bringing it to on-prem.

It’s really two different philosophies in action. We now see VMware doing more for the development community with vSphere Integrated Containers (VIC), Docker Containers, Kubernetes, and Pivotal Cloud foundry. Meanwhile Microsoft is looking to implement the Azure stack for on-prem environments, and they are focusing more on infrastructure. In the end, enterprises will have terrific choices as the software defined data center frees up customers dollars and management time.

The podcast runs ~25 minutes. Lee is a very knowledgeable individual and although he doesn’t qualify as a Greybeard (just yet), he has been in and around the data center and flash storage environments throughout most of his career. From his diverse history, Lee has developed a very business like perspective on data center and storage technologies and it’s always a pleasure talking with him.  Listen to the podcast to learn more.
