B Disk array supported emulations

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]).

NOTE:
For 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 external
storage LDEVs to be configured without losing data. Using any other emulation may cause data loss
in the external storage LUNs.
