2 Business Copy/Snapshot planning and design
This chapter describes requirements for setting up and using SS and includes data pool sizing
information.
Consistency group system requirements
The following table includes a list of consistency group system requirements.
NOTE: Many of these requirements are augmented with restrictions.
Requirement Item
BC/SS is required to operate SS. Install and enable the P9500 (P9500) storage
system hardware, microcode, and software required for BC/SS operations. Software
Consider the capacity of the volume when purchasing licensed capacity.
Capacity for SS is part of the licensed capacity for BC/SS. Ensure that the License capacity
licensed capacity for BC/SS is more than the combined capacity needed for
both software applications.
The number of software applications using a volume does not increase the
amount of licensed capacity that you must purchase.
Required: Shared memory
•
SS/VFS1: 716.8 MB (RACK model is supported up to VFS1.)
• SS/VFS2: 1,021 MB (VFS1 + 307 MB)
•
SS/VFS3: 2,045 MB (VFS1,2 + 1024 MB)
•
SS/Extension 1: 4,096 MB (SS/VFS1 + 3379.2 MB)
P9500 storage systems can handle a 7.15 TB database with seven generations.
Verify that your system is installed with the appropriate SS V-VOL management
area.
Restriction:
•
You cannot share the V-VOL management area memory with Thin
Provisioning (THP).
RAID Manager is required for you to perform SS pair operations. RAID Manager
requires that you use one volume as a command device. RAID Manager
For more information about setting up the RAID Manager, see the HP XP P9000
RAID Manager Reference Guide.
The P-VOL, V-VOL, and volumes must be logical volumes (LDEVs). Volume type
For more information about volume type, see the following:
• “Data pool requirements and restrictions” (page 13)
• “External volumes” (page 22)
To maintain performance levels, use the following configurations:
•
Do not mix normal volumes and data pool-VOLs in the same parity group.
•
Ensure that the data pool-VOLs consist of LDEVs from multiple parity groups.
•
Assign different processor blade identifiers to LDEVs that make up data
pool-VOLs.
For more information about assigning the processor blade identifier, see
the HP XP P9000 Provisioning for Open Systems User Guide.
(For P-VOL, V-VOL, and data pool-VOLs) OPEN-V Emulation type
V-VOL limit per P-VOL: 64 Pair configuration
