Ibm Aix; Supported Emulations; Emulation Specifications - HP XP20000/XP24000 Configuration Manual

IBM AIX

This appendix provides information about supported emulations and device type specifications.
Some parameters might not be relevant to your array. Consult your HP representative for information
about supported configurations for your system.

Supported emulations

HP recommends using OPEN-V as the emulation for better performance and features that may not
be supported with the legacy emulations (OPEN-[389LE]).
Table 48 Supported emulations

XP12000
XP20000
XP24000
SVS200
NOTE: For the SVS 200, and the XP24000/XP20000/XP12000/XP10000 when connected to
external storage devices, HP recommends using OPEN-V as the emulation the array makes visible
to the host. This allows configuration of external storage LDEVs without losing data. Using any
other emulation may cause data loss in the external storage LUNs.
