Abstract
A storage array controller may include a virtual machine manager for managing a storage array application virtual machine and a dedicated multiplexer virtual machine. The storage array application virtual machine and the dedicated multiplexer virtual machine may be communicatively coupled via a plurality of virtual machine manager coupling drivers. The storage array controller may also include a dedicated inter controller link for communicatively coupling the storage array controller with a second storage array controller. The dedicated multiplexer virtual machine may be configured for coupling with a second dedicated multiplexer virtual machine included with the second storage array controller via a device driver communicating across the dedicated inter controller link.
