Instant clones generate a large volume of traffic during the provisioning process due to the method used to create the VMs. Since the in-memory VM Fork technology creates the machines quickly, the volume of traffic is significant. The I/O required to complete the creation is brief but large, with View Storage Accelerator helping to improve performance during I/O-intensive instant clone activities. The VDI administrator must plan for bursts of high traffic on PowerStore when creating or refreshing pools of instant clone VMs. Dedicate a PowerStore array to VDI when supporting a large VDI implementation so other workloads are not impacted.
For this design, three instant clone pools are configured with 850, 850, and 800 desktops respectively. Three Horizon Connection server instances are used in this environment. The servers were installed as replica instances, meaning that all three instances of Connection Server are identical. This configuration ensures load balancing and high availability within the environment. A randomization algorithm is applied to the login order to spread the login load evenly across the connection servers to optimize performance.
