capacity
NOTE:
To calculate the capacity for data in a hard disk drive associated with a CLPR, add the fol owing
formulas:
Number of parity groups: capacity of one disk x 3 x (3D+1P)
Number of parity groups: capacity of one disk x 6 x (6D+2P)
Number of parity groups: capacity of one disk x 7 x (7D+1P)
Number of parity groups: capacity of one disk x 2 x (2D+2D)
NOTE:
To add cache memories to the local array, install them with Standard Cache Access Model or High
Performance Cache Access Model mode. If the local array has additional printed circuit boards
(PCBs), you must use the High Performance Cache Access Model mode. For more information about
additional cache memories, contact your HP account support representative.
• Restriction on CLPR and CU group
You cannot allocate parity groups belonging to different CU groups to a CLPR other than CLPR0.
For more information about CU groups, see the HP StorageWorks XP Remote Web Console user
guide for XP12000/XP10000/SVS200.
Storage management logical partitions (SLPRs)
An array can be shared with multiple organizations, for example, enterprises and departments within
an enterprise. Therefore, multiple administrators who belong to different organizations might manage
one array. This creates the potential for an administrator who belongs in one organization to destroy
other organizations' volumes. Furthermore, it can complicate and increase the difficulty of managing the
array because of an incorrect operation by an administrator and its influence on other organizations.
The storage management logical partition function in XP Disk/Cache Partition allocates all of an array's
resources (that is, ports and CLPRs) to multiple virtual arrays. Each virtual array can be accessed by only
its administrator. Therefore, this prevents the risk that an administrator will destroy another organization's
volumes or leak another organization's data.
In a non-partitioned environment, a full array is considered one single partition SLPR0. After the array is
partitioned, SLPR0 becomes the unpartitioned portion of the array. Similarly, CLPR0 contains all parity
groups (PGs) and cache in the non-partitioned environment. After the array is partitioned, CLPR0 contains
the remaining PGs and cache that are not allocated to other CLPRs.
Figure 2 shows an example of when one array is partitioned into two virtual arrays. Each virtual array is
allocated to two enterprises respectively. In this case, enterprise A's array administrator can manage
enterprise A's virtual array, but cannot manage one of enterprise B's arrays. Similarly, enterprise B's array
administrator can manage enterprise B's virtual array, but cannot manage one of enterprise A's arrays.
IMPORTANT:
Disk/cache partitioning for the SVS200 is limited to one SLPR and four CLPRs.
