Tech Preview: vCenter Site Recovery Manager with ActiveCluster

An increasingly common use case for Active-Active replication in vSphere environments is vSphere Metro Storage Cluster (vMSC) which I wrote about in this paper recently:

This overviews how a stretched vSphere cluster interacts with the active-active replication we offer on the FlashArray called ActiveCluster. Continue reading Tech Preview: vCenter Site Recovery Manager with ActiveCluster

ActiveCluster and vMSC Implementation Guide

Quick post. I have published my ActiveCluster implementation guide for vSphere Metro Storage Cluster (vMSC). You can find it here:

ActiveCluster, if you are unfamiliar, is the Pure Storage FlashArray implementation of fully Active/Active replication. Meaning a volume can exist and take write simultaneously from two arrays. No additional hardware or licenses required. Comes with Purity 5.0.0. A main focus, like everything else Pure, is simplicity–that goal has definitely been achieved in my view.

ActiveCluster and VAAI

Pure Storage recently offered up support for active/active replication for the FlashArray in a feature called ActiveCluster. And a common question that comes up for active/active solutions alongside VMware is how is VAAI supported?

The reason it is asked is that it is often tricky if not impossible to support in an active/active scenario. Because the storage platform first has to perform the operation on one array, but also on the other. So XCOPY, which offloads VM copying, is often not supported. Let’s take a look at VAAI with ActiveCluster, specifically these four features:

  1. Hardware Assisted Locking (ATOMIC TEST & SET)
  2. Zero Offload (WRITE SAME)
  3. Space Reclamation (UNMAP)
  4. Copy Offload (XCOPY)

Setting Up FlashArray Active/Active Replication (ActiveCluster)

In Purity 5.0 Pure Storage released support for Active/Active replication on the FlashArray. This provides the ability to present the same storage volume simultaneously from two different FlashArrays.

For a good overview, check out this video:

Announcing Pure Storage FlashArray VVol GA

This is a blog post I have been waiting to write for a long time. We at Pure Storage are pleased to announce that vSphere Virtual Volume support on the FlashArray is officially GA!

The FlashArray now supports running VVols in Purity 5.0.0 and later. The cool thing about the FlashArray is the flexibility of the Purity Operating Environment–so VVols are supported on all FA 400 models (405, 420, and 450), //M models (m10, m20, m50, m70) and FlashArray//X.
