Hitachi TrueCopy for z/OS (T1711-96009, June 2006)

18 TrueCopy for the XP1024/XP128/XP12000/XP10000
Components
TC390 operations involve the XP1024/XP128/XP12000/XP10000 (and/or other XP disk arrays) at the
main and remote sites, the physical communications paths between the main and remote disk arrays, and
the Command View XP management station or XP Remote Web Console. The main and remote disk arrays
must have the same controller emulation. TC390 copies the original online data at the main site to the
offline backup volumes at the remote site through the dedicated Fibre Channel remote copy connections.
The Command View XP management station or XP Remote Web Console hosts the TC390 software and
provides a user-friendly Window®s-based graphical user interface (GUI) for all TC390 functions and
operations. The I/O time-stamping host software function, provided by MVS DFSMSdfp, is required for
TC390A consistency groups that span multiple disk arrays. Error reporting communications (ERC) is
required for effective disaster recovery with TC390.
Figure 1 on page 18 and Figure 2 on page 19 show the TC390 components and their functions. The
TC390 components are:
• XP1024/XP128/XP12000/XP10000
• Main and remote control units (MCUs and RCUs)
• Volume pairs (local M-VOLs and remote R-VOLs)
