On top of this, there is a new on-disk format (v3) and a new software checksum mechanism. All of these features introduce some capacity overhead in their own right, so as to allow administrators track where the storage consumption is occurring a brand new capacity view has been introduced with VSAN 6.2.

As part of that session, the topic of VSAN memory consumption was raised. In the past, we’ve only ever really talked about the host memory requirements for disk group configuration as highlighted in this post here. For example, as per the post, to a run a fully configured Virtual SAN system, with 5 fully populated disk groups per host, and 7 disks in each…
