When many users require the same desktop image, you can create one large automated pool from a single template or parent virtual machine. By using a single base image and pool name, you can avoid dividing the machines arbitrarily into smaller groups that must be managed separately. This strategy simplifies your deployment and administration tasks.
To support large pools, you can create pools on ESXi clusters that contain up to 32 ESXi hosts. You can also configure a pool to use multiple network labels, making the IP addresses of multiple port groups available for the virtual machines in the pool.
