The Dell EMC PowerMax and VMware vSphere Configuration Guide

For those customers running on PowerMax, I've published the new The Dell EMC PowerMax and VMware vSphere Configuration Guide which is the replacement for Using Dell EMC VMAX and PowerMax Storage in VMware vSphere Environments. The new TechBook only covers PowerMax integration/best practices with VMware. While the previous doc was over 400 pages, the new... Continue Reading →

SRDF/Metro Smart DR

One of the new features we released with the latest PowerMaxOS is known as SRDF/Metro Smart DR, or MetroDR for short. MetroDR expands the previous functionality of a third leg off the R1 or R2 of an SRDF/Metro pair by allowing either the R1 or R2 to update the third leg. In essence this is... Continue Reading →

FC-NVMe on PowerMax detail

I've been delayed in updating my documentation for vSphere 7 and as we have a new release for PowerMax coming out soon, I can't publish what I have as it is intertwined with pre-GA material. Therefore I'm going to add some detail here about using FC-NVMe on PowerMax in vSphere 7 in the meantime. I'm... Continue Reading →

PowerPath/VE 7.0 – NVMeoF (FC-NVMe) support

A real short post to let you know that PowerPath version 7.0 released today with support for vSphere 7.0 and NVMe over Fabrics - or specifically FC-NVMe. I wrote about vSphere 7 and FC-NVMe here if you need a refresher. Dell EMC of course recommends using PP/VE as a best practice with VMware.    

Load balancing VAAI commands in PP/VE

I had a recent query concerning whether PowerPath/VE supported the load balancing of VAAI commands. Though I was fairly certain this feature was added, my memory not being what it used to be, I did some digging to confirm. Most of the VAAI commands - ATS, WRITE SAME, and UNMAP were added in PP/VE 6.1... Continue Reading →

SRDF SRA TechBook 9.1

I published the latest SRDF SRA TechBook version 9.1 today. You can get it here. A reminder that this TechBook only covers SRA 9.x. Prior SRA versions are in the original TB which is located in the documentation library. Besides the changes for 9.1, I added some sections which I have covered in this blog... Continue Reading →

SRDF/Metro and vMSC BPs WP

I finally managed to cobble together enough time to complete a whitepaper on best practices when running Dell EMC SRDF/Metro with VMware vSphere Metro Storage Cluster (vMSC) that has been on my list for some time. I have an older paper on this topic but its focus was more on the application side - in... Continue Reading →

vSphere 6.7 U1 & NMP latency

In vSphere 6.7 VMware released, albeit without fanfare, a new type of NMP, latency. Most customers probably never even knew it was there - I was among them until a colleague told me about it. In Update 1 of 6.7 released today here, they've supplied the documentation to go along with the feature so we'll... Continue Reading →

vSphere LUN and path maximums

This week I had question from our field concerning a customer and LUN/device maximums which I think is useful to share. The customer was running vSphere 6.5 which supports 512 LUNs per ESXi host (per target/array) but they were unable to see any beyond 255. Now before 6.5, I frequently heard from customers who hit...
