  • System and method for managing I/O access policies in a storage environment employing asymmetric distributed block virtualization
    Patent number: 7627699
    Abstract: A system employing asymmetric distributed block virtualization includes a volume server, a plurality of volume clients, and one or more physical block devices. The volume server aggregates storage in the physical block devices into a logical volume and makes the logical volume accessible to the volume clients for input/output (I/O) operations. In order to manage different I/O access requirements (such as read-only access versus read-write access) of the volume clients, the volume server maintains a different I/O access policy for each volume client to control the kinds of input/output operations that the volume client is allowed to perform on the logical volume.
