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.
