HP P9000 Provisioning for Mainframe Systems User Guide (AV400-96369, October 2011)

System requirements
• The P9500 hardware, microcode, and Remote Web Console essential for operating the
storage system be installed and configured for use.
• A P9500 storage system.
• The storage system must have parity groups installed.
• A Remote Web Console client computer.
Shared memory requirements
If configuring thin provisioning, Thin Provisioning Z requires dedicated shared memory for the
V-VOL management area.
The V-VOL management area, which is automatically created when shared memory is added, is
an area used to store information for associating pool-VOLs and THP V-VOLs.
If Thin Provisioning Z is used, at least 16 GB of shared memory consisting of two sections is
required. The memory capacity allocated to each part is as follows:
• Basic part: 8 GB
• Thin Provisioning Z: 8 GB
The required shared memory is installed by your HP representative.
