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.

67: GreyBeards talk infrastructure monitoring with James Holden, Sr. Prod. Mgr. NetApp

Sponsored by: Howard and I first talked with James Holden, NetApp Senior Product Manager for OnCommand Insight and Cloud Insights,  last month, at Storage Field Day 16 (SFD16) in Waltham, MA. At the time, we thought it would be great to also have him on the show.

James has been with the NetApp OnCommand Insight (OCI) team for quite awhile now and is very knowledgeable about the product and its technology. NetApp Cloud Insights is a new SaaS offering that provides some of the same services as OCI without the footprint, focused on newer, non-traditional applications and available on a pay as you go model.

NetApp OnCommand Insight (OCI)

NetApp OCI is sort of a stripped down, souped up enterprise SRM tool, without storage and servers configuration-provisioning (see James’s introduction video from SFD15 for more info). It supports NetApp and just about anyone’s storage including Dell EMC, IBM, Hitachi Vantara (HDS), HPE, Infinidat, and Pure Storage as well as most major OSs such as VMware vSphere, Microsoft HyperV, RHEL, etc. Other storage can easily be  added to OCI through a patch/minor update and is typically done by customer request.

NetApp OCI currently runs in some of the biggest enterprises  in the world today, including top F500 companies and one of the world’s largest banks. OCI is agentless but does use a data collector server/VM onprem or in cloud that takes advantage of storage and system APIs to gather data.

OCI provides extensive end-to-end infrastructure monitoring and trouble shooting (see James’s SFD16 OCI monitoring & troubleshooting session). OCI monitors application workloads from VMs to the storage supporting them.

OCI also supplies extensive charge back capabilities (see his SFD16 OCI cost control/chargebacks session). In times like these when IT competes with public cloud offerings every day, charge backs can be very illuminating.

Also, OCI has extensive integration with ServiceNOW and similar offerings (see SFD16 OCI ecosystem session). With this level of integration, OCI can provide seamless tracking of service requests from initiation to completion through verification.

In addition, OCI can monitor public cloud infrastructure as well as onprem. For example, with Amazon Web Services (AWS), customers can use OCI to monitor EC2 instances EBS IO activity. OCI reports on AWS IOPS rates by EC2-EBS connection. Customers paying for EBS IOPS, can use OCI to monitor and tailor their EBS costs. OCI also supports Microsoft Azure environments.

NetApp Cloud Insights

NetApp Cloud Insights, a new SaaS offering, that is currently in Public Preview status but is expected to release in October, 2018 (checkout his SFD16 Cloud Insights session video).

Customers can currently register to use the preview version at Cloud.netapp.com/Cloud Insights. There’s a registration wall but that’s all it takes to get started. .

The minimum Cloud Insights instance is a single server and 5TB of storage. Unlike OCI, Cloud Insights is tailored to support smaller shops without significant infrastructure. However, Cloud Insight also offers standard onprem enterprise infrastructure monitoring as well.

Cloud Insights is also focused on modern, cloud-native applications whether they operate on prem or in the cloud. The problem with cloud native, container apps is that they come and go in seconds, and there’s thousands of them. Cloud Insights was designed specifically for container and other cloud native applications and as such, should provide a more accurate monitoring of operations for these systems.

We talked about Cloud Insight’s development cadence. James said that because it’s a SaaS offering new Cloud Insights functionality can be released daily, if not more frequently. Contrast that with OCI, where they schedule 3-4 releases a year.

Cloud Insight currently supports the Kubernetes container ecosystems today but more are on the way. Again, customers determine which Container or other cloud native ecosystems will be supported next.

The podcast runs ~22 minutes. James was very knowledgeable about OCI, Cloud Insights and infrastructure monitoring in general and he was easy to talk with. Howard and I had a great time at SFD16 and enjoyed our time talking with him again on the podcast.  Listen to the podcast to learn more.

James Holden, Senior Product Manager NetApp OCI and Cloud Insights 

 

James Holden is a Senior Manager of Product Management at NetApp, and for the last 5 years  has been building the infrastructure monitoring and reporting tool OnCommand Insight.

Today he is working across NetApp’s Cloud Analytics portfolio, including Cloud Insights, a new SaaS offering currently in preview.

Prior to NetApp, James worked for 14 years at CSC in both the US and the UK on their storage, compute and automation solutions.

 

 

65: GreyBeards talk new FlashSystem storage with Eric Herzog, CMO and VP WW Channels IBM Storage

Sponsored by:

In this episode, we talk with Eric Herzog, Chief Marketing Officer and VP of WorldWide Channels for IBM Storage about the FlashSystem 9100 storage series.  This is the 2nd time we have had Eric on the show (see Violin podcast) and the 2nd time we have had a guest from IBM on our show (see CryptoCurrency talk). However, it’s the first time we have had IBM as a sponsor for a podcast.

Eric’s a 32 year storage industry veteran who’s worked for many major storage companies, including Seagate, EMC and IBM and 7 startups over his carreer. He’s been predominantly in marketing but was CFO at one company.

New IBM FlashSystem 9100

IBM is introducing a new FlashSystem 9100 storage series, using new NVMe FlashCore Modules (FCM) that have been re-designed to fit a small form factor (SFF, 2.5″) drive slot but also supports standard, NVMe SFF SSDs in a 2U appliance package. The new storage has dual active-active RAID controllers running the latest generation IBM Spectrum Virtualize software that’s running over 100K storage systems in the field today.

FlashSystem 9100 supports up to 24 NVMe FCMs or SSDs, which can be intermixed. The FCMs offer up to 19.2TB of usable flash and have onboard hardware compression and encryption.

With FCM media, the FlashSystem 9100 can sustain 2.5M IOPS at 100µsec response times with 34GB/sec of data throughput. Spectrum Virtualize is a clustered storage system, so one could cluster together up to 4 FlashSystem 9100s into a single storage system and support 10M IOPS and 136GB/sec of throughput.

Spectrum Virtualize just introduced block data deduplication within a data reduction pool. With thin provisioning, data deduplication, pattern matching, SCSI Unmap support, and data compression, the FlashSystem 9100 can offer up to 5:1 effective capacity:useable flash capacity. That means with 24 19.2TB FCMs, a single FlashSystem 9100 offers over 2PB of effective capacity.

In addition to the appliances 24 NVMe FCMs or NVMe SSDS, FlashSystem 9100 storage can also attach up to 20 SAS SSD drive shelves for additional capacity. Moreover, Spectrum Virtualize offers storage virtualization, so customers can attach external storage arrays behind a FlashSystem 9100 solution.

With FlashSystem 9100, IBM has bundled additional Spectrum software, including

  • Spectrum Virtualize for Public Cloud – which allows customers to migrate  data and workloads from on premises to the cloud and back again. Today this only works for IBM Cloud, but plans are to support other public clouds soon.
  • Spectrum Copy Data Management – which offers a simple way to create and manage copies of data while enabling controlled self-service for test/dev and other users to use snapshots for secondary use cases.
  • Spectrum Protect Plus – which provides data backup and recovery for FlashSystem 9100 storage, tailor made for smaller, virtualized data centers.
  • Spectrum Connect – which allows Docker and Kubernetes container apps to access persistent storage on FlashSystem 9100.

To learn more about the IBM FlashSystem 9100, join the virtual launch experience July 24, 2018 here.

The podcast runs ~43 minutes. Eric has always been knowledgeable on the enterprise storage market, past, present and future. He had a lot to talk about on the FlashSystem 9100 and seems to have mellowed lately. His grey mustache is forcing the GreyBeards to consider a name change – GreyHairsOnStorage anyone,  Listen to the podcast to learn more.

64: GreyBeards discuss cloud data protection with Chris Wahl, Chief Technologist, Rubrik

Sponsored by:

In this episode we talk with Chris Wahl, Chief Technologist, Rubrik. This is our second time having Chris on our show. The last time was about three years ago (see our Chris on agentless backup podcast). Talking with Chris again was great and there’s been plenty of news since we last spoke with him.

Rubrik now has three products the Rubrik Cloud Data Protection suite (onprem, virtual or in the [AWS & Azure] cloud), the Rubrik Datos IO (recent acquisition) for NoSql database with semantic dedupe and Rubrik Polaris GPS, a SaaS monitoring/trending/management solution for your data protection environment. Polaris GPS monitors and watches data protection trends for you, to insure all your data protection SLAs are being met. But we didn’t spend much time on Polaris.

Datos IO was designed from the start to backup new databases based on NoSQL technologies and provides, a semantic based deduplication capability, that’s unique in the industry . We talked with Datos IO before their acquisition by Rubrik (see our podcast with Tarun on 3rd generation data protection).

Cloud Data Protection

As for their Cloud Data Protection suite, one major differentiator is that all their functionality is available via RESTful APIs. Their GUI is completely built off their APIs. This means any customer could use their set of APIs to integrate Rubrik data protection with any application/workload on the planet.

Chris mentioned that Rubrik has 40+ specific application/system integrations that provide “strictly consistent” data protection. We assume this means application consistent backups and recovery but goes beyond mere applications.

With the Cloud Data Protection solution, data resides on the appliance for only a short (customer specifiable) period and then is migrated off to cloud or onprem object storage. The object storage could be any onprem S3 compatible storage, in the AWS or Azure cloud. It’s completely automatic. The data migrated to object storage is self-defining, meaning that metadata and data are all available in one spot and can be restored anywhere there’s a Rubrik Cloud Data Protection suite operating.

The Cloud Data Protection appliance also supports onboard search and analytics to search backup/recovery metadata/catalogs. As such, there’s no need to purchase other tools to uncover which backup files exist. Their solution also uses data deduplication to reduce the data stored.

Data stored is also encrypted by customer keys and use HTTPS to transfer data. So, data is secured at rest, secured in flight and deduped. Cloud Data Protection also offers data mobility. That is it can move your VMs and data from onprem to the cloud and use Rubrik in the cloud to rehydrade the data and translate your VMs to run in AWS or Azure and it works in reverse, translating AWS/Azure compute instances into VMs.

Rubrik’s major differentiator is simplicity. Traditionally, customers had been conditioned to thinking data protection took hours to maintain, fix and keep running. But with Rubrik Cloud Data Protection, a customer just points it to an application and selects an SLA, and Rubrik takes over from there.

The secret behind Rubrik’s simplicity is Cerebro. Cerebro is where they have put all the smarts to understand a data center’s infrastructure, applications/VMs, protected data and requested SLAs and just makes it work

The podcast runs ~27 minutes. Chris was great to talk with again and given how long it’s been since we last talked, he had much to discuss. Rubrik seems like an easy solution to adopt and if their growth is any indicator, customers agree. Listen to the podcast to learn more.

63: GreyBeards talk with NetApp A-Team members John Woodall & Paul Stringfellow

Sponsored by NetApp:

In this episode, we talk with NetApp A-Team members John Woodall (@John_Woodall), VP Eng, Integrated Archive Systems and Paul Stringfellow (@techstringy), Technical Dir.  Data Management Consultancy, Gardner Systems Plc.

Both John and Paul have been NetApp partners for quite awhile (John since the beginning of NetApp). John and Paul work directly with infrastructure customers in solving customer, real world data problems.

NetApp A-Team is a select, small (only 25 total) group of individuals that are brought together periodically and briefed by NetApp Execs and Product managers. A-Team membership is for life (as long as they continue to work in IT and not for a competitor). The briefings span a number of topics but are typically about what NetApp plans to do in the near term. The A-Team is there to provide a customer perspective to NetApp management and product teams.

Oftentimes, big companies can lose sight of customer problems and having a separate channel that’s engaged directly with customers can sometimes bring to light these issues. By having the A-Team, NetApp is getting feedback on customer problems and concerns from partners that directly engage with them.

Both Howard and I were very impressed that when John and Paul introduced themselves they mentioned DATA rather than storage. This signalsa a different perspective from pure infrastructure to a more customer view.

Following that theme, Howard asked about how customers were seeing the NetApp Data Fabric. This led to a long discussion of just what NetApp Data Fabric represents to customers in this multi-cloud world today. NetApp’s Data Fabric provides choice on where customers can run their work, liberating work that previously may have be stuck in the cloud or on prem.

Ray asked about how NetApp is embracing the cloud. What with cloud data volumes (see earlier NetApp sponsored podcast), NPS, Cloud ONTAP and other cloud solutions NetApp has lit up in various public clouds.  John mentioned that public preview for Cloud Data Volumes should free up by end of the year and at that time anyone can use it.

I was at a dinner with NetApp, 3-5 years ago, when the cloud looked like a steamroller that was going to grind infrastructure providers into dust. I was talking with a NetApp executive, he said they were doing everything they could at the time to figure out how to offer value with cloud providers rather than competing with them. Either you embrace change or you’re buried by it.

At the end of the podcast, Howard turned the discussion to NetApp HCI. Paul said, at first HCI was just shrunk infrastructure, but now, its more about the software stack on top of HCI that matters. The stack enables simpler deployment and configuration flexibility. From a NetApp HCI perspective, flexibility in being able to separately add more compute or storage is a strong differentiator.

The podcast runs ~30 minutes. Both John and Paul were very knowledgeable about current IT trends. I think we could have easily talked with them for another hour or so and not exhausted the conversation.  Listen to the podcast to learn more.
