Quick post here. As some of you may or may not know, the SRDF and VMware Site Recovery Manager techbook that I have “owned” for four years or so is now out of my hands since I moved onto a different role within EMC. Drew Tonnesen (drewtonnesen.wordpress.com) from Symmetrix Engineering is now the author of the book. Anyways the techbook has been updated to include the latest changes included in the SRDF SRA version 5.5.1 which we released a few weeks ago.
As I wrote about in a recent post the 5.1 version of the SRDF Storage Replication Adapter was updated in a service release. Similar fixes and a few other changes have been also added to the SRDF SRA version 5.5. If you are running VMware Site Recovery Manager version 5.1 or 5.5 this is the SRA you should be using. SRM 5.0 users can only use the 5.1 SRA (while the 5.1 SRA supports SRM 5.0 and 5.1 I recommend SRM 5.1 users use the 5.5 SRA).
So what’s new in the latest SR for SRDF SRA (220.127.116.11)?
The service release for the Symmetrix SRDF Storage Replication Adapter version 5.1 has been posted and is available for download. This isn’t a must-update release for most users but there are some important changes in them that will be very relevant for a few environments. This release will be numbered 18.104.22.168 but in some places may be referred to as 5.1.1.
Recently I had a partner/customer who was migrating a lot of SAP data from one VMAX to another VMAX and they ran into an issue they weren’t sure how to solve, well at least what the best way to solve it was. This person had a ton of data on the VMAX and more than a few TimeFinder/VP Snap point-in-time copies of each SAP volume that they used for testing/recovery or backup.
For those of you unfamiliar with VP Snap it is a rather new (introduced with 5876) method of local replication on the VMAX that leverages the space-efficiency benefits of TimeFinder/Snap but also offers the flexibility of configuration provided by TimeFinder/Clone.
