A building block consists of physical servers, a vSphere infrastructure, Horizon View servers, shared storage, and virtual machine desktops for end users. You can include up to five building blocks in a Horizon View pod.

Example of a LAN-Based View Building Block for 2,000 Desktops



vSphere clusters

1 or more

80-port network switch


Shared storage system


vCenter Server with View Composer on the same host

1 (can be run in the block itself)


MS SQL Server or Oracle database server (can be run in the block itself)


3 (a 1Gbit Ethernet network for each: management network, storage network, and VMotion network)

With vSphere 4.1 and later versions, each vCenter Server can support up to 10,000 virtual machines. This support enables you to have building blocks that contain more than 2,000 View desktops. However, the actual block size is also subject to other Horizon View-specific limitations.

If you have only one building block in a pod, use two View Connection Server instances for redundancy.
