As an administrator or architect you should always ensure your designs are within the product’s Maximums and Limits in order to be entitled to VMware Support.
Horizon View 5.3 introduced new features and improvements, specially adding supportability for multiple different OS and VSAN integration in Technology Preview mode. This Horizon View release is not particularly focused on scalability, like the previous release and you will not see any differences when comparing with Horizon View 5.2.
The limits may vary according to the releases in use. The limits in this post are specific to Horizon View 5.3 and vCenter Server 5.5.
· 180 VMs per NFS export with VAAI support – NEW!
For Horizon View 5.3 VMware decided to utilize NFS exports instead of SCSI LUNS. For this reason this is a new number in my limits table. Please note that this is not an effective limit, but rather a recommended number based on VMware’s tests.

Horizon View 5.3 introduces Tech Preview for VSAN. Administrators may start testing Horizon View with VSAN in a dev/test environment; but please remember that there’s no VMware support for the integration at this point in time.
VSAN reduces CAPEX for Horizon View deployments by leveraging inexpensive server disks for shared storage, avoiding the capital expense of specialized hardware.VSAN helps to reduce OPEX by greatly simplifying, and in most cases eliminating, day-to-day storage configuration and provisioning activities, yet allowing administrators to scale Horizon View deployments on-demand by adding hosts on the fly or hot-adding disks to existing server nodes.
If want to learn more about the VSAN benefits for Horizon View please refer to my article How does VMware VSAN help Horizon View?
As I aforementioned, VSAN is not supported with Horizon View 5.3. However, VMware ran validation tests before shipping the product. Here are the numbers validated by VMware.
If you decide to deploy VSAN with Horizon View in you test/dev lab environment you should ensure your deployment is within the tested numbers for a successful Technology Preview.
