Preparing the Storage System and Remote Web Console Computers
Hardware and Software Requirements
Before launching XP Thin Provisioning, you must take several preliminary steps. These include the
following:
•
Install the storage system.
•
Install the Remote Web Console computers, and connect them to the storage system internal
LAN.
•
Enable XP Thin Provisioning on each storage system where you intend to use the option.
•
If you intend to use XP Thin Provisioning V-VOLs as XP Business Copy P-VOLs or S-VOLs, you
must also install XP Business Copy Software. For detailed instructions on enabling Remote
Web Console product options, see the HP XP24000/XP20000 Remote Web Console User
Guide.
•
If you intend to increase the capacity of V-VOL, XP RAID Manager must be installed on your
host server.
License Requirements
You will need an XP Thin Provisioning license for the total pool capacity. Licensed capacity for XP
Thin Provisioning Software is priced per storage system. If you are using XP Disk/Cache Partition,
you are not charged for license capacity per storage logical partition (SLPR).
If you are using XP Business Copy, XP Continuous Access, or XP Continuous Access Journal, you
need a license for the total consumed pool capacity in use by all P-VOLs and S-VOLs. If the total
used pool capacity exceeds the licensed capacity, the additional capacity is treated as a temporary
license. You will be able to use the additional capacity for 30 days. After 30 days, you will not
be able to perform XP Business Copy operations except for deleting pairs. After 30 days, you will
not be able to perform XP Continuous Access or XP Continuous Access Journal operations except
for suspending copy operations and deleting pairs. For more information about temporary license
capacity, see the HP XP24000/XP20000 Remote Web Console User Guide.
Shared Memory Requirements
XP Thin Provisioning requires its own dedicated shared memory for the V-VOL management area,
which is separate from the shared memory for XP Snapshot. The required shared memory will be
installed by your HP service representative.
Operating System and File System Capacity
Initializing a P-VOL in most operating systems and file systems consumes some XP Thin Provisioning
pool space. Some operating system—file system combinations initially take up little pool space
while other combinations take as much pool space as the virtual capacity of the V-VOL.
Table 9 (page 23) shows the effects of those combinations. For more information, contact your HP
service representative.
