HP XP7 Business Continuity Manager User Guide (TK954-96005)

Continuous Access Synchronous Z (Cnt Ac-S Z)
Performs and manages remote synchronized volume copy operations between a storage system
on the primary site and a storage system on the secondary site, so each S-VOL is always identical
to its P-VOL counterpart.
TrueCopy Asynchronous for Mainframe (TCA)
Stores data and control information for each P-VOL in a sidefile, and performs and manages the
remote copying of volumes independently (asynchronously) of the host I/O processes.
