SRDF SRA and SRM Test Failover review

Occasionally I'll get a question from a customer or even employee about doing failover testing in SRM with our SRDF SRA. While I have this documented extensively in the TechBook (TB), and most who contact me have been trying to use it, perhaps it is the very detailed nature of it that makes it challenging...

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 →

VMworld Europe update – NVMeoF

I'm attending VMworld in Barcelona Spain this week delivering a session on NVM and NVMe, the same one I delivered in Las Vegas in fact...well almost. Our development team has made some great progress on the next generation of connectivity, NVMeoF or NVMe over fabric, so I am including a demonstration on that. To that... Continue Reading →

VSI 7.4 – PowerMax support

So I believe this is our last VMware integration product to be certified with PowerMax. VSI 7.4 is still based on the vSphere Web Client, though the HTML 5 client is coming along - Q3 I'd guess at this point though don't quote me. As I mentioned before, the continuation of the Web Client version... Continue Reading →

vSphere 6.7 & SRM 8.1

Today VMware has posted the newest release of their flagship vSphere product, 6.7. In addition they have also dropped Site Recovery Manager (SRM) 8.1. A new vSphere release always means lots of new features, and I'd be a fool to try to enumerate them seeing as there is a document for that. I'll mention a... Continue Reading →

vSphere 6.7 automated UNMAP enhancements

Continuing from vSphere 6.7 post... So in vSphere 6.5 VMware introduced automated UNMAP for datastores. In so doing they offered users two option: on (default) or off. Rather than a checkbox, however, VMware has what appears to be a scale which would allow the user to decide how aggressive UNMAP should be. It didn't work... Continue Reading →

Thick or thin VMDKs on VMAX

Thick or thin? This is a question I get in almost all best practice discussions with customers and while I cover it in the TechBook and elsewhere, I thought I'd do a quick post on it without all the extras. VMware offers 2 types of disks - thick or thin - and 3 disk types - thin, zereoedthick,... Continue Reading →

SRDF SRA and SRM 6.5 support

Customers will be happy to learn that the SRDF SRA which supports VMware SRM 6.5 is now GA. SRDF SRA 6.3 is released in conjunction with our newest HYPERMAX OS Q2 2017 release which was announced at Dell EMC World. You can get the SRA here. As I've noted in other posts, our SRA is tied to our VMAX... Continue Reading →

VMware-VMAX integration

This week at Dell EMC World I presented a session on the ways the VMAX platform integrates into VMware software. Essentially this is my job, figuring out where we can integrate and then whether we should integrate - and of course all that follows - researching, testing, documenting, etc. We already have lots of integration points...
