Integration with VUM, VMware Update Manager

vSAN 6.6.1 is fully integrated with VUM to provide a powerful new update process that makes sure your vSAN cluster is up to date.

vSAN Performance Diagnostics:

The feature offers advice such as increasing a stripe width, adding more VMs or bringing more disk groups into use to improve performance. The feature needs the Customer Experience Improvement Program (CEIP) to be enabled, as well as the vSAN Performance Service. Once these have been configured, and the diagnostic information has been gathered for approx. 1 hour, benchmark results can then be examined to see if the maximum number of IOPS, maximum throughtput or minimum latency has been achieved. If not, guidance is provided on how best to achieve these objectives in a benchmark run.



Improved vCenter and unicast behaviour for cluster membership:

If vCenter is down and changes are then made to the cluster, when vCenter recovers, it may reset those cluster changes(UUID ). In vSAN 6.6.1, there is a new property for vSAN called “configuration generation”. This addresses the issue of tracking vSAN membership and will avoid the issue.
