Comments

This new product announcement represents a strategic move for Dell EMC and a compelling offering in the hot mid-range market segment. The product was announced some time ago and finally arrived in 2020 as the company can't wait any longer even if some features are missing today or planned for the future (see below). The concept is interesting as it offers consolidation of usages - storage only or computer + storage - on the same platform thus reducing TCO. Also all features are included with flexible Opex models.

The successor of previous Dell EMC mid-range products, especially Unity, and discontinued VNX, often in conflict, coming from acquisitions like XtremIO, Compellent or EqualLogic or not, introduces a compelling model mixing a pure storage array - PowerStore T - exposing block or block + file interfaces as an unified appliance with dual active/active nodes. Of course, classic interfaces are exposed such FC/iSCSI and NFS/SMB protocols in the base appliance but no NVMe over Fabrics. The Unity NAS service also present on Unity/Unity XT has been containerized and included into PowerStore OS.

The new flavor is the PowerStore X as a combination of block storage array combined with a dual server within the same chassis able to run applications on the embedded ESXi thanks to AppsON and vVols. This is new but creates friction with other Dell EMC VM-oriented and storage + compute convergence solutions even if AppsON targets storage intensive applications.

Dell EMC makes a real effort to provide an universal solution for the mid-range both in term of applications and workloads you can run and use, also for components, and finally for the protocols exposed. Having designed and built a system with PowerStore OS as a container-based architecture leveraging microservices is a key achievement and demonstrates the modularity of the solution. We also anticipate the usage of such approach for the other future Dell EMC storage products.

Adding NVMe dual ported Intel Optane or NVMe SSDs in 2U systems provides performance gain. 3 NVMe entities are possible: NVRAM for write cache, SCM and SSD and you cannot mixed Optane with SSD in same enclosure. You can do NVRAM + SCM or NVRAM + SSD, all SSD are 3D TLC.

When additional capacity and performance are needed, 2 options are possible: a scale-up with the base appliance connected to 3 SAS-based expansion enclosures maximum for a total of 100 SSDs (25 NVMe + 75 SAS) and scale-out model only available for the T model coupling 4 base appliances maximum i.e 8 nodes. And a cluster can be mixed between 1000, 3000, 5000, 7000 or 10000 models. There is no storage difference between all these models, just CPUs, with different number of cores and memory sizes, we detect also some clock differences, the maximum capacity per appliance is approximately 900TB raw for 817TB usable.

We still have some difficulties with the slogan The future of storage is here on the Dell EMC product page. Future means to be ready for things - circumstances, events, needs and climate - not seen today but anticipated. The immediate comment is PowerStore uses Intel Xeon limited today with PCIe Gen 3 as Intel doesn't have ready Gen 4 capabilities for Xeon family. Intel even recently announced some direction for Optane with PCie Gen 4. Gen 4 is definitely the future, so why Dell EMC finally creates this limitation for this product, does the company receive some guarantee from Intel, may be? On the other hand, AMD Epyc processors already support PCIe Gen 4 and we started to see some U.2 SSDs like Samsung PM1733 and PM1735, Kioxia CD6 and CM6, Netint Codensity D408 SSD to list some or even M.2 SSDs like Adata XPG Sage, Sabrent Rocket, GigaByte Aorus, Corsair MP600 and Samsung again as controllers continue to pop up in different places from Marvell, Innogrit, Microchip/Microsemi, Phison or Netint to name a few.

The second remark about this future direction is the SAS utilization when you need to add capacity to the base appliance. We expect Dell EMC is working on NVMe-oF to upgrade this model, even if here it's for capacity extension and the system considered mid-range. At the same time, Dell signed with Lightbits Labs to offer a NVMe/TCP embedded with the PowerEdge 740xd XL server. It could be an idea and Dell Technologies Capital is also an investor in Lightbits Labs.

In a cluster mode, the file server behavior is limited to the master appliance whatever the number of appliances connected to it. The result is a file service delivered only by a pair of HA nodes, Dell EMC estimates this is enough in mid-range.

In terms of data protection, only a RAID-5 mode is offered in 4+1 or 8+1 configurations and we expected at least a double parity and even a wide erasure coding mode when 4 chassis are coupled with 96 or 98 SSD drives. What about a fixed schema N+2 even +3 with a large N? We find more sophisticated protection in competitive products.

Beyond data protection, data services are pretty rich and we even find similar data reduction ratio i.e 4:1 just announced by Hitachi Vantara for their VSP E990.

PowerStore is an interesting concept and now a real product. We understand Dell EMC push especially for the X model. The T model is a bit behind as engineers spent time on the high level design, tools and integration (AppsON, CloudIQ, vVols, Data Reduction, vRO, CSI/Kubernetes, vSphere/ESXi, Ansible, etc.) and let for the future some storage aspect especially SAS replacement, PCIe Gen 4 and NVMe over Fabrics.

In term of competition, we identify several players for model T or X.

For the T model, pure storage, unified as block + file interfaces or not, we can list:

  • Hitachi Vantara VSP E990,
  • Pure Storage FlashArray,
  • NetApp AFF A400,
  • IBM FlashSystem 9200, 7200,
  • HPE Nimble Storage,
  • Quantum F-2000,
  • StorCentric Vexata and Pavilion Hyperparallel, and
  • Infinidat Infinibox,

For model X, of course all players offering some sort of compute + storage converging models are competitors. The good thing here again is the choice and flexibility plus agility the platform offers.
