6.4.4 vSAN
vSAN is supported in vCloud Director and can be used as a storage tier for tenants through manually-created storage policies that relate to vSAN capabilities.
The following are Virtual SAN design considerations:
• vSAN datastore is an object that is tightly related to a single vSphere cluster. It cannot provide storage to different vSphere clusters.
• VMware does not recommend using vSAN storage for catalogs. All catalog media images (ISO files) are uploaded by vCloud Director as file objects into a directory structure under a single folder. If the same vSAN datastore is used as a storage policy for different catalogs, they all share one VM Home Namespace object with a maximum size of 255 GB.
• Third-party virtual storage appliances that consume vSAN storage and provide NFS file services can be used to provide catalog across clusters with scale above 256 GB.
