The practice of separating management components onto a dedicated vSphere cluster has become common practice in recent years. However, such a cluster should aim to have no dependencies on the production systems with one of the key requirements being that any type of incident or outage affecting the production system does not affect the management cluster, and likewise any management cluster outage cannot affect the production workload systems.

In the past, providing dedicated out-of-band storage for management-only clusters could be cost-prohibitive. It was necessary to purchase additional independent storage hardware for management clusters that could provide the performance and availability required for I/O-intensive and highly available virtual machines, as well as to provide expensive isolated storage fabric to provide connectivity to the management-only array. VMware Virtual SAN provides a highly performant shared storage platform across the vSphere cluster making it possible to significantly reduce costs whilst maintaining enterprise levels of availability and performance.

This makes Virtual SAN the ideal choice to provide true out-of-band management storage to a dedicated management cluster, making this type of truly independent management environment a viable and affordable option for most medium and large organizations.

This white paper provides a detailed rational and design for utilizing Virtual SAN in a dedicated management environment.
