B Disk array supported emulations This appendix provides information about supported emulations and device type specifications. Some parameters may 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]).

B Disk array supported emulations
This appendix provides information about supported emulations and device type specifications. Some
parameters may 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 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 external storage LDEVs to be configured without losing data. Using any other emulation
may cause data loss in the external storage LUNs.
