#90 – Dell EMC's Enterprise NVMe Strategy with Vince Westin (Sponsored)

This week, Chris talks to Vince Westin, Technical Evangelist within the PowerMax Group at Dell EMC.  PowerMax is the latest in a storage product line with lineage back to the original Symmetrix systems of the early 1990s.  PowerMax is an all-NVMe storage array, reflecting an industry move towards faster, low latency media.  Vince takes us through the rationale for moving to NVMe across the Dell portfolio and PowerMax in particular.

Some of the more interesting aspects of the transition include the ability to simplify code paths with NVMe compared to back-end SAS.  NVMe introduces a shared PCIe fabric and increases parallelism across the infrastructure.  This results, of course, in lower latency for specific workloads like high random I/O.

In 2019 we can expect to see Storage Class Memory being introduced into the PowerMax family.  This brings challenges around how data should be encrypted and whether data optimisation is worthwhile, bearing in mind the additional performance overhead.

You can find Vince’s personal blog at https://applyit.typepad.com/ and the specific post relating to SCM and PowerMax here.  We also recommend viewing the Storage Field Day 16 videos of Vince’s presentation on PowerMax, which helps to fill in the visual gaps missing from the podcasting format!
