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.

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...

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...

APD/PDL in vSphere 6 with VMAX and VPLEX

Recently I have seen a number of internal emails here at EMC asking about our recommendations around All Paths Dead (APD) and Permanent Device Loss (PDL) in vSphere 6 on our storage arrays - mostly VPLEX to be specific.  There have been significant changes in APD/PDL in vSphere 6 which is why the questions are...
