HP XP P9500 Storage - Manual (Page 13)

2 Requirements and specifications
This chapter provides basic system requirements, along with specifications for BCM, PPRC, and
other mainframe-related interfaces and functions. In addition to the information in this chapter,
“Planning for Continuous Access Synchronous Z” (page 25) provides many specifications,
recommendations, and restrictions for the elements of a Continuous Access Synchronous Z system
that require attention before setting up and using Continuous Access Synchronous Z.
System requirements
Continuous Access Synchronous Z operations require P9500 main and remote disk array containing
the M-VOLs and R-VOLs, data paths between the disk arrays, host(s) on the primary and remote
sites, and interface software.
The following lists and describe general requirements.

Mainframe related •
IBM PPRC is supported.
• If the R-VOL is assigned to the M-VOL of Continuous Access Journal Z, and the main
and/or remote systems consist of several CPU complexes, a SYSPLEX timer is required
to provide a common time reference for the host I/O timestamping function.
