Item Requirement
Data drive type You can use SAS, SSD, FMD, FMD DC2, and FMD-HDE.
Regardless of the type of the volume (internal volume or external volume),
you can use pool-VOLs with different drive types in the same pool. For best
performance, use pool-VOLs with the same drive type in the same pool.
For more information about data drive type, see Pool creation and data
drive type priority on page 94.
CLPR Registering pool-VOLs to Cache Logical Partition Numbers (CLPRs) in
pools:
You can register pool-VOLs assigned to different CLPRs in a pool.
Changing CLPRs:
You can change CLPRs in the parity group belonging to the pool-VOL. In
this case, regardless of the CLPR in the pool-VOL, the CLPR ID in the
parity must be the same as that of the P-VOL that you are using.
Pool limit 1,024
Volume capacity 8 GB to 4 TB
Path definition Define only needed paths to a volume so that you can specify the volume
as a pool-VOL.
Fast Snap data pool requirements
The following table lists the requirements for Fast Snap data pools.
For information about THP pools, see the HPE XP7 Provisioning for Open Systems User Guide .
Item Requirement
Pool capacity Calculate the pool capacity (see Calculating and assigning pool
capacity on page 69).
The maximum total capacity of pools in a storage system depends
on the storage system model:
12.3 PB (if THP/Smart/Real Time Smart Tier/FS Extension1, THP/
Smart/Real Time Smart Tier/FS Extension2, or THP/Smart/Real
Time Smart Tier/FS Extension3 is added in the shared memory
capacity).
The maximum pool capacity that can be used for each Fast Snap
P-VOL is 768 TB.
Pool-VOL limit per pool 1,024
Note: You cannot assign a volume that is already assigned to a
pool as a pool-VOL to another pool.
