storage system consists of the main control unit (primary storage system) and SVP. The secondary
storage system consists of the remote control unit (secondary storage system) and SVP.
To provide greater flexibility and to enable the XP disk array to be tailored to unique customer
operating requirements, operational parameters, or optional modes, are available in URz for the
XP storage system. At installation, the XP disk array modes are set to their default values, so make
sure to discuss these settings with your HP team. The XP disk array modes can only be changed
by your HP representative.
