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 →


VSI 7.3

Happy New Year everyone. It's been a bit since I've posted but we do have a new VSI release to talk about. This one comes late as we do normally release quarterly, but seeing as it wasn't expected at all, I suppose a month late isn't bad. So last time I wrote about VSI, I mentioned 7.2 was most...

Down Protection Site: VMware SRM TestFailover with the SRDF SRA

One of the great features of VMware SRM is the ability to run a test failover without impacting either the protection or recovery site. When using the SRDF SRA this means the replication between the R1 and the R2, whether asynchronous or synchronous, will not be broken. The SRA uses TimeFinder technology to accomplish this,...

VMAX TB and best practices

I've just completed the latest update to the VMAX/VMware TechBook, a tome (I can be derogatory since it's mine) of some 400 plus pages that explains how best to use VMware on the various VMAX/VMAX3/VMAX AFA arrays. You can find it here. When customers ask me about best practices, a link to this doc is... Continue Reading →

vRA and VVols redux

About a year ago I published a post on integrating vRealize Automation 7 (vRA) with VVols. At that time the implementation was really a manual process because VMware had not created a Storage Policy Based Management (SPBM) package for vRA 7, only version 6. In September of last year VMware finally updated the SPBM package... Continue Reading →


SRDF Adapter Utilities End of Life

The SRDF Adapter Utilities (SRDF-AU) is a free, optional plug-in that provides a GUI interface to modify the XML files that are part of the SRDF SRA for VMware SRM and used primarily in testing. The SRDF-AU only runs on Windows and therefore requires that one of the vCenters in an SRM configuration is running on Windows.... Continue Reading →


SnapVX and Oracle Data Guard

I'm off the beaten path today courtesy of a friend and colleague in Chicago. We both used to work at Oracle so when he gives me a call it's typically not about my VMAX/VMware fare. In this case he had a customer who wanted to use SnapVX to instantiate a physical standby database, i.e. Data Guard.... Continue Reading →


VSI 7.1 eNAS compression/deduplication

VSI 7.1 is now available for download and while not a blockbuster on the VMAX front since we had ours with the 7.0 version, there are a couple minor updates and one new feature. Let's start with the minor changes. The first is that 7.1 adds support for the vSphere 6.5 Web Client. (vSphere 6.5 does... Continue Reading →


VMAX VVol replication with RP4VM

Our VVol implementation has been out for well over a year now and we've had our share of customers wanting to take the technology for a spin. When VMware first introduced support in vSphere 6 - what is known as VVol 1.0 and VASA 2.0 - they did not offer replication capabilities for array vendors.... Continue Reading →
