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.

61: GreyBeards talk composable storage infrastructure with Taufik Ma, CEO, Attala Systems

In this episode,  we talk with Taufik Ma, CEO, Attala Systems (@AttalaSystems). Howard had met Taufik at last year’s FlashMemorySummit (FMS17) and was intrigued by their architecture which he thought was a harbinger of future trends in storage. The fact that Attala Systems was innovating with new, proprietary hardware made an interesting discussion, in its own right, from my perspective.

Taufik’s worked at startups and major hardware vendors in his past life and seems to have always been at the intersection of breakthrough solutions using hardware technology.

Attala Systems is based out of San Jose, CA.  Taufik has a class A team of executives, engineers and advisors making history again, this time in storage with JBoFs and NVMeoF.

Ray’s written about JBoF (just a bunch of flash) before (see  FaceBook moving to JBoF post). This is essentially a hardware box, filled with lots of flash storage and drive interfaces that directly connects to servers. Attala Systems storage is JBOF on steroids.

Composable Storage Infrastructure™

Essentially, their composable storage infrastructure JBOF connects with NVMeoF (NVMe over Fabric) using Ethernet to provide direct host access to  NVMe SSDs. They have implemented special purpose, proprietary hardware in the form of an FPGA, using this in a proprietary host network adapter (HNA) to support their NVMeoF storage.

Their HNA has a host side and a storage side version, both utilizing Attala Systems proprietary FPGA(s). With Attala HNAs they have implemented their own NVMeoF over UDP stack in hardware. It supports multi-path IO and highly available dual- or single-ported, NVMe SSDs in a storage shelf. They use standard RDMA capable Ethernet 25-50-100GbE (read Mellanox) switches to connect hosts to storage JBoFs.

They also support RDMA over Converged Ethernet (RoCE) NICS for additional host access. However I believe this requires host (NVMeoF) (their NVMeoY over UDP stack) software to connect to their storage.

From the host, Attala Systems storage on HNAs, looks like directly attached NVMe SSDs. Only they’re hot pluggable and physically located across an Ethernet network. In fact, Taufik mentioned that they already support VMware vSphere servers accessing Attala Systems composable storage infrastructure.

Okay on to the good stuff. Taufik said they measured their overhead and it was able to perform an IO with only an additional 5 µsec of overhead over native NVMe SSD latencies. Current NVMe SSDs operate with a response time of from 90 to 100 µsecs, and with Attala Systems Composable Storage Infrastructure, this means you should see 95 to 105 µsec response times over a JBoF(s) full of NVMe SSDs! Taufik said with Intel Optane SSD’s 10 µsec response times, they see response times at ~16 µsec (the extra µsec seems to be network switch delay)!!

Managing composable storage infrastructure

They also use a management “entity” (running on a server or as a VM),  that’s used to manage their JBoF storage and configure NVMe Namespaces (like a SCSI LUN/Volume).  Hosts use NVMe NameSpaces to access and split out the JBoF  NVMe storage space. That is, multiple Attala Systems Namespaces can be configured over a single NVMe SSD, each one corresponding to a single  (virtual to real) host NVMe SSD.

The management entity has a GUI but it just uses their RESTful APIs. They also support QoS on an IOPs or bandwidth limiting basis for Namespaces, to control manage noisy neighbors.

Attala systems architected their management system to support scale out storage. This means they could support many JBoFs in a rack and possibly multiple racks of JBoFs connected to swarms of servers. And nothing was said that would limit the number of Attala storage system JBoFs attached to a single server or under a single (dual for HA) management  entity. I thought the software may have a problem with this (e.g., 256 NVMe (NameSpaces) SSDs PCIe connected to the same server) but Taufik said this isn’t a problem for modern OS.

Taufik mentioned that with their RESTful APIs,  namespaces can be quickly created and torn down, on the fly. They envision their composable storage infrastructure to be a great complement to cloud compute and container execution environments.

For storage hardware, they use storage shelfs from OEM vendors. One recent configuration from Supermicro has hot-pluggable, dual ported, 32 NVMe slots in a 1U chasis, which at todays ~16TB capacities, is ~1/2PB of raw flash. Taufik mentioned 32TB NVMe SSDs are being worked on as we speak. Imagine that 1PB of flash NVMe SSD storage in 1U!!

The podcast runs ~47 minutes. Taufik took a while to get warmed up but once he got going, my jaw dropped away.  Listen to the podcast to learn more.

Taufik Ma, CEO Attala Systems

Tech-savvy business executive with track record of commercializing disruptive data center technologies.  After a short stint as an engineer at Intel after college, Taufik jumped to the business side where he led a team to define Intel’s crown jewels – CPUs & chipsets – during the ascendancy of the x86 server platform.

He honed his business skills as Co-GM of Intel’s Server System BU before leaving for a storage/networking startup.  The acquisition of this startup put him into the executive team of Emulex where as SVP of product management, he grew their networking business from scratch to deliver the industry’s first million units of 10Gb Ethernet product.

These accomplishments draw from his ability to engage and acquire customers at all stages of product maturity including partners when necessary.

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.

57: GreyBeards talk midrange storage with Pierluca Chiodelli, VP of Prod. Mgmt. & Cust. Ops., Dell EMC Midrange Storage

Dell EMC Midrange Storage

In this episode we talk with Pierluca Chiodelli  (@chiodp), Vice President of Product, Management and Customer Experience at Dell EMC Midrange storage.  Howard talked with Pierluca at SFD14 and I talked with Pierluca at SFD13. He started working there as a customer engineer and has worked his way up to VP since then.

This is the second time (Dell) EMC has been on our show (see our EMCWorld2015 summary podcast with Chad Sakac) but this is the first sponsored podcast from Dell EMC. Pierluca seems to have been with (Dell) EMC forever.

You may recall that Dell EMC has two product families in their midrange storage portfolio. Pierluca provides a number of reasons why both continue to be invested in, enhanced and sold on the market today.

Dell EMC Unity and SC product lines

Dell EMC Unity storage is the outgrowth of unified block and file storage that was first released in the EMC VNXe series storage systems. Unity continues that tradition of providing both file and block storage in a dense, 2 rack U system configuration, with dual controllers, high availability, AFA and hybrid storage systems. The other characteristic of Unity storage is its tight integration with VMware virtualization environments.

Dell EMC SC series storage continues the long tradition of Dell Compellent storage systems, which support block storage and which invented data progression technology.  Data progression is storage tiering on steroids, with support for multi-tiered rotating disk (across the same drive), flash, and now cloud storage. SC series is also considered a set it and forget it storage system that just takes care of itself without the need for operator/admin tuning or extensive monitoring.

Dell EMC is bringing together both of these storage systems in their CloudIQ, cloud based, storage analytics engine and plan to have both systems supported under the Unisphere management engine.

Also Unity storage can tier files to the cloud and copy LUN snapshots to the public cloud using their Cloud Tiering Appliance software.  With their UnityVSA Software Defined Storage appliance and VMware vSphere running in AWS, the file and snapshot data can then be accessed in the cloud. SC Series storage will have similar capabilities, available soon.

At the end of the podcast, Pierluca talks about Dell EMC’s recently introduced Customer Loyalty Programs, which include: Never Worry Data Migrations, Built-in VirtuSteram Storage Cloud, 4:1 Storage Efficiency Guarantee, All-inclusive Software pricing, 3-year Satisfaction Guarantee, Hardware Investment Protection, and Predictable Support Pricing.

The podcast runs ~27 minutes. Pierluca is a very knowledgeable individual and although he has a beard, it’s not grey (yet). He’s been with EMC storage forever and has a long, extensive history in midrange storage, especially with Dell EMC’s storage product families. It’s been a pleasure for Howard and I to talk with him again.  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.
