Abstract
A method and apparatus for processing a write request at a storage device is provided. A write request that identifies a sender of the write request is received at a storage device. The write request is examined to determine the identity of the sender. A determination is made as to whether, within a hierarchical relationship, the sender is subordinate to any entity that has been designated as being unable to perform write requests at the storage device. Upon determining that (a) the sender is not subordinate to any entity that has been designated as being unable to perform write requests at the storage device, and (b) the sender has not been designated as being unable to perform write requests at the storage device, the sender is allowed to write to the storage device. Thereafter, the write request from the sender may be performed at the storage device.
