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 R2 with SRM in a disconnected state

Last May we introduced our latest SRDF SRA, version 9. This release offers a new feature, the ability to run a test failover when the production site is unavailable. I spoke about this in a post at that time which is available here.  Some customers choose to run the test with just the host network... Continue Reading →

TechBook update for PowerMax

Well PowerMax has been out for a few months now but I only just finished my VMAX/PowerMax/VMware TechBook update here. It's always a bear to be perfectly honest since it encompasses all best practices but the blog can only buy me so much time before we need it in official form. I've managed to get...

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 →

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...

SRDF SRA & SRM TestFailover with existing snapshots

********************************************************************* An updated version of this using PowerMax is also available here. ********************************************************************* 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... 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 →
