Deploy maximum number of virtualized environments on the same host.

Deploy the virtualized environment on the same cluster if the cluster goes beyond the host boundary.

Segment redundant elements on a different cluster, or ensure that the redundant elements are not on the same host.

Create a tiered or segmented cluster infrastructure that isolates critical applications, such as Avaya Aura® applications, from other virtual machines.

Plan for rainy day scenarios or conditions. Do not configure resources only for traffic or performance on an average day.

Do not oversubscribe network resources, oversubscribing affects performance. To ensure consistent and predictable behavior, latency-sensitive traffic such as A1, B1, A2, and B2 must be strictly isolated from any contention-prone VMs shared on the same host. Implement hard isolation mechanisms and enforce guaranteed minimum bandwidth, along with traffic prioritization to protect these flows from performance impact.

Monitor the server, host, and virtualized environment performance.
