Virtual SAN 6.2 -Technical What’s New (Boston VMUG)

This was an awesome session that explained the new features coming with the 6.2 update for vSAN a couple of improvements.

  1. The first of which is QOS this is a great feature that was added to VSAN. This gives the user inside information on the IOPs that are being used per VMDK including ,setting limits on the individual VMDK, a truly great feature. GONE ARE THE DAYS OF IOP HOGS ON VSAN! Now we can control and part out IOPS to the most used VM’s on the cluster without having to worry about performance hits.
  2. VSAN dedupe and compression: this is a must have feature that just got introduced for VSAN 6.2 the ability to dedupe and compress your data keeps cost per GB down significantly.
  3. Software checksum for VSAN: the ability to check and remediate corruption on your VSAN is obviously important. And this will help and do a great job on making sure there is consistency on your data and it is corruption free while using VSAN 6.2
  4. Probably the most important of these features added are the performance Service. Now we can store and keep historical VSAN metrics on an independent database away from Vcenter for when there is issues. There is a host of other features also including cluster host and VM metrics that are tied to the VSAN performance services. Giving us an in-depth look into the capabilities of our VSAN and were potential problems will arise from.

Ontop of this there is a new health services feature that will continually check the health of the VSAN cluster and make sure nothing is out of whack! What a great tool and awesome improvement to VSAN!
