The Universal Storage Platform V/VM is configured with OPEN-V LU types. The
OPEN-V LU can vary in size from 48.1 MB to 4 TB. For information on other LU
types (OPEN-3, OPEN-9), contact your Hitachi Data Systems representative.
For maximum flexibility in LU configuration, the USP V/VM provides the Virtual
LVI/LUN (VLL) and LUN Expansion (LUSE) features. Virtual LVI/LUN allows
users to configure multiple LUs under a single LDEV, and LUN Expansion
enables users to concatenate multiple LUs into large volumes. For further
information on Virtual LVI/LUN and LUN Expansion, please refer to the Virtual
LVI/LUN and Volume Shredder User’s Guide (MK-96RD630) and the LUN
Expansion User’s Guide (MK-96RD616).
