vSAN 6.6 download links are publicly available.

Today VMware has released vSAN 6.6 to the public! 6.6 is a big step forward. While the base architecture of vSAN stays the same, it becomes more and more efficient. With the price of flash going down, it’s an even more compelling reason to look into HCI these days.

One of my favorite use cases for vSAN is with VMware Horizon Advanced/Enterprise editions. To me, it’s a no brainer. Simple, elastic scalability, much higher performance over traditional tiered storage and lower TCO. Not long ago storage in VDI environments would have given most of us nightmares.

What’s New

  • Unicast – In vSAN 6.6, cluster communication has been redesigned to use unicast traffic. Multicast is no longer required on the physical switches to support the vSAN cluster.
  • Enhanced Stretched Clusters with Local Failure Protection – Previously, vSAN was able to provide a fully active-active, stretched cluster. vSAN 6.6 takes this a step further, allowing for storage redundancy within a site AND across sites at the same time.
  • Encryption – vSAN supports data-at-rest encryption of the vSAN datastore. When encryption is enabled, vSAN performs a rolling reformat of every disk group in the cluster.
  • Site Affinity for Stretched Clusters – A new feature for vSAN 6.6 Stretched Clusters is the ability to configure site affinity.
  • Configuration Assist and Updates – New Configuration Assist and Updates pages allows to check the configuration of your vSAN cluster, and resolve any issues.
  • Resynchronization throttling – IOPS used for cluster resynchronization can be throttled to prevent performance bottlenecks.
  • vSAN Health Command Line Tool – A new esxcli command allows to check vSAN health from the command line (esxcli vsan health).
  • Degraded Device Handling – vSAN 6.6 provides a more proactively stable environment with the detection of degraded and failing devices.
