( )The vMSC listings typically also provide a link to the specifics of the implementation by the partner. Before purchasing, designing or implementing please consult the PVSP listing to ensure the partner has filed for PVSP and has tested with the correct vSphere versions. vMSC configurations are now fully partner supported and can be found on the website under PVSP (Partner Verified and Supported Products). As of vSphere 6.0 this is no longer needed.
Note that initially, vMSC storage configurations had to go through a mandatory certification program. For detailed information about storage implementations, refer to the documentation provided by the appropriate VMware storage partner. This paper explains how vSphere handles specific failure scenarios, and it discusses various design considerations and operational procedures.
This recommended practice document was developed to provide additional insight and information for the operation of a vMSC infrastructure in conjunction with VMware vSphere. VMware vSphere® Metro Storage Cluster (vMSC) is a specific storage configuration that is commonly referred to as stretched storage clusters or metro storage clusters. These configurations are usually implemented in environments where disaster and downtime avoidance is a key requirement.
