Boolean operators of AND, OR and NOT connect predicates together on the information items that will be pushed to them. The method includes dynamic cost / credit adjustment based profile indexing and matching.

A “Logging” method and apparatus is provided to protect control unit cached data not yet written to backing storage disk drives. This recording mechanism will copy “WRITE DATA” to a log at a target logically or physically external (to the storage controllers) location equally common to all members of the set of distributed storage control units managing a common storage pool. Upon the failure of one the members of the set of control units, the “Log” information is available to insure that pending “write” data is written to the proper location on the disk drives upon a recovery action. One of the surviving members of the set assumes control of the storage managed by the failing unit by utilizing the recorded information to insure that data not written to backing storage (disks) up to the point of failure is then written to the disk backing storage. The surviving member of the set recovering the failing control unit storage (disk set) ownership will thereby “flush” (WRITE) the Journaled WRITE DATA to the backing storage disk drives before allowing normal operations to proceed.
