About:

Basics to get started with Virtual SAN:

  • Minimum of 3 fully licensed vSphere hosts are required for Virtual SAN (VSAN) to operate. However, I recommend a minimal recommended cluster size is 4 nodes.

Next you will want to size your hosts:

  • evo

 

Important Note: Make sure the hardware you choose for your new hosts is on the Virtual SAN Compatibility Guide.

Use the Virtual SAN Calculator (VSAN) to determine how many hosts, ssd, memory and components you need to build your new Virtual SAN or the chart below:

As for deployments and more technical info:

There is a great quick start guide on kb.vmware.com here: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2073795

Also, here are a few unwritten tidbits about Virtual SAN limitations when used in a Horizon View deployment:

  • This release does not support using the Horizon View space-efficient disk format feature, which reclaims disk space by wiping and shrinking disks.
  • Virtual SAN does not support the VMware vSphere Storage APIs – Array Integration (VAAI) feature because Virtual SAN does not use NAS devices.
  • 100 Virtual machines per host (there is a 3000 component limit per hosts and each composer clone can use up to 24 components) do not exceed more than 75% utilization on magnetic disk.

Virtual SAN is compatible with the View Storage Accelerator feature. Virtual SAN provides a caching layer on SSD disks, and the View Storage Accelerator feature provides a content-based cache that reduces IOPS and improves performance during boot storms. For more information on Virtual SAN configuration maximums please see the section “VMware Virtual SAN” in the VMware vSphere 5.5 Configuration Maximums guide.

Reference Architecture team worked very hard on the View 5.3 Virtual SAN reference architecture whitepaper, which is available here:
