vMSC and Disk.AutoremoveOnPDL on vSphere 6.x and higher

Advertise here with BSAI have discussed this topic a couple of times, and want to inform people about a recent change in recommendation.

SMP-FT and (any type of) stretched storage support

Advertise here with BSAI had a question today around support for SMP-FT in an EMC VPLEX environment. It is well known that SMP-FT isn’t supported in a stretched VSAN environment, but what about other types of stretched storage? Is that a VSAN specific constraint? (Legacy) FT appears to be supported for VPLEX and … [Read more...]

Conservative vs Aggressive for VMCP APD response

Advertise here with BSAI just finished writing the vMSC 6.0 Best Practices paper which is about to be released when a question came in. The question was around the APD scenario and whether the response to an APD should be set to aggressive or conservative. Its a good question and my instinct immediately says: … [Read more...]

Manage your VMware Metro Storage Cluster with Tags

Running a VMware vSphere Metro Storage Cluster (VMware vMSC) makes it possible to move VMs between two geographical locations without downtime. In a Metro Storage Cluster a vSphere Cluster consists of ESXi hosts from both locations with shared storage that is stretched over these locations. Using a VMware Metro Storage … [Read more...]
