SAN Volume Controller
Abstract: A stretched IBM SAN Volume Controller configuration in conjunction with VMware vSphere enables transparent VMware vMotion migration and automatic VMware High Availability (HA) failover of virtualized workloads between physical datacenters. This paper provides an introduction to the IBM SAN Volume Controller product. The hardware, architecture, concepts, and features and functions are reviewed. The stretched configuration of IBM SAN Volume Controller is examined, including requirements and best practices that need to be implemented to ensure availability of the solution. The paper then investigates how to set up and provision storage from IBM SAN Volume Controller to VMware vSphere ESXi hosts. Test scenarios that were completed for this paper and demonstrate the flexibility and availability of this solution are examined. Finally, a customer implementation of a stretched SAN Volume Controller cluster and VMware vSphere is referenced.
