Explanation: The SAN Volume Controller stretched cluster configuration provides a continuous availability platform, whereby host access is maintained in the event of the loss of any single failure domain. This availability is accomplished through the inherent active/active architecture of SAN Volume Controller along with the use of volume mirroring. During a failure, the SAN Volume Controller nodes and associated mirror copy of the data remain online and available to service all host IO. The existing SAN Volume Controller stretched cluster configuration has two locations, each with one node from each I/O group pair. The quorum disks are usually held in a third location. This solution is very successful in the field for many IBM clients. It allows SAN Volume Controller hardware to be geographically distributed, resembling how IBM Metro Mirror is deployed.
