VMware vSphere® Metro Storage Cluster (vMSC) is a specific configuration within the VMware Hardware
Compatibility List (HCL). These configurations are commonly referred to as stretched storage clusters or metro
storage clusters and are implemented in environments where disaster and downtime avoidance is a key
This best practices document was developed to provide additional insight and information for operation of a vMSC infrastructure in conjunction with VMware vSphere. This paper explains how vSphere handles specific failure scenarios, and it discusses various design considerations and operational procedures. For detailed information about storage implementations, refer to documentation provided by the appropriate VMware storage partner.
