VSAN Erasure Coding – Storage Based Policy Management

A new policy setting has been introduced to accommodate the new RAID-5/RAID-6 configurations in VSAN (only available in All-Flash configuration). Minimum 4 hosts will be required for RAID5, and minimum 6 hosts will be required for RAID6 configuration.

This new policy setting is called Failure Tolerance Method. This policy setting takes two values: performance and capacity. When it is left at the default value of performance, objects continue to be deployed with a RAID-1/mirror configuration for the best performance. When the setting is changed to capacity, objects are now deployed with either a RAID-5 or RAID-6 configuration.

The RAID-5 or RAID-6 configuration is determined by the number of failures to tolerate setting. If this is set to 1, the configuration is RAID-5. If this is set to 2, then the configuration is a RAID-6.

Consideration to Deploy Edge Cluster in vCloud Director. Also discussing about VSAN Architecture.

If we are using vCloud Director, then Edge Cluster can not be combined with the management cluster. It can only be combined with the resource/payload/workload cluster.

If we are using VSAN, there are several consideration too if we want to use it as management cluster.

Please read these references to explain detail of the technical stuffs:

Once again, thanks Bayu for the discussion.
