B Disk array supported emulations

This appendix provides information about supported emulations and emulation 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 8 Supported emulations
XP model
XP10000
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.
