3-site SRDF with VMware SRM

As there is a 500 page TechBook on SRDF with SRM, it might seem a bit redundant to be covering a topic like this again, and perhaps it is; but as I have worked with customers and support over many months (and years), a few issues seem to recur. It's usually at that point I figure... Continue Reading →


SRDF SRA – Python script for masking functionality

Back in March we offered customers a way to generate the EmcSrdfSraTestFailoverConfig.xml file for the SRDF SRA test failover functionality when using the vCenter Appliance (VCSA). You can read all about that here. Recently we had a customer request to enhance the script to add the ability to create the EmcSrdfSraDeviceMaskingControl.xml file and our developer Sam went...

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,...

SRDF SRA & SRM TestFailover with existing snapshots

Can the SRDF SRA use an older snapshot/clone/etc. rather than taking a fresh copy each time? Very occasionally I get this question from customers, particularly those who have seen the RecoverPoint functionality. For those who are not familiar with RecoverPoint (RP), it is another replication technology that we have that permits both local and remote... Continue Reading →


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 →

RecoverPoint 5.1 for VMAX3/AFA

The previously announced version 5.1 of RecoverPoint that supports VMAX3/VMAX All Flash is now available for download here. I covered the RP capability with VMAX3/AFA in this post in May. Just a quick reminder that this is an asynchronous solution for local and/or remote replication, protects at the storage group level, and works with the current RP... 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 →
