Abstract
Collaboration between discrete systems and a shared system to consolidate shared storage-related services. In one example, shared, consolidated storage-related services and high-availability are provided by pairing each of a plurality of discrete block storage virtualization modules residing on each discrete computer system to a shared block storage virtualization module residing on a shared computer system, and maintaining logical volume coherency locally by each of the plurality of discrete block storage virtualization modules, and globally by the shared block storage virtualization module. Additionally, allocation of a set of block storage virtualization functions to be performed by at least one of the plurality of discrete block storage virtualization modules or the shared block storage virtualization module can be made according to the pairing.
