PowerFlex with VMware SRM

Now that I've covered replication on the PowerFlex, we can move right into VMware SRM. Like all storage-based replication, PowerFlex has an SRA that integrates with SRM and executes those tasks specific to the PowerFlex. The current version of the SRA is 1.0.0.1 and supports through PowerFlex 3.x. Support for 4.x is currently undergoing certification.... Continue Reading →

Partial SRDF/Metro 3-site with SRM (SRA)

I recently ran across a customer configuration I had not seen before with 3-site SRDF/Metro (ASYNC leg with failovertoasync site set in Global XML), and it gave me some concern. Let me talk about the setup and then cover the concerning aspects. I will say from the outset, I actually didn't think this setup was... Continue Reading →

Reprotect SRDF before reprotect SRM

I have worked with a number of companies that have a DR requirement that their production environment switch sites (for the sake of this post we are speaking of a traditional two site configuration) every six months. Think of this as taking the place of regular testing at the DR site. Really then these companies... Continue Reading →

But there are a few items to discuss concerning the release, one a new requirement, the second a bug fix which... Continue Reading →

SRM 8.5

SRM 8.5 was released a couple days ago now (10.5.21) and offers some interesting additions. At the top I'll note that our SRDF SRA 9.2.x is compatible with SRM 8.5. For many point releases, VMware does not significantly alter how SRM works and thus simply brings certification forward from the previous release. Since we support... Continue Reading →

Partial VM Replication in SRM

I've been working with SRM a long time, but here's a situation I honestly have never been asked about: Can you replicate only some vmdks of a VM? Why yes you can, and it has nothing to do with changing parameters in the SRDF SRA (which I am sure is a relief). This is a... Continue Reading →

PiTs with SRM and the SRDF SRA

I wanted to revisit this post on using point-in-time (PiTs) with SRM and the SRDF SRA having just demonstrated SRM with virtual and physical infrastructure. A dual purpose environment was the original impetus for adding the parameter IgnoreActivatedSnapshots so many years ago now, and as it has been four years since the post I thought...
