Pools, Controllers – HP StoreOnce Backup User Manual
Page 131
HP StoreOnce 2700, 4500, and 4700 Backup systems:
There is always one enclosure for the internal storage.
If the model supports additional enclosures, each installed shelf will be listed.
•
HP StoreOnce 2700 Backup cannot be expanded.
•
HP StoreOnce 4500 Backup supports the addition of up to three expansion enclosures; these
may contain 12 x 2TB or 12 x 4TB disks. The 48TB capacity expansion enclosure includes a
hot spare disk in Slot 12, when not in use its LED indicators will be off and it will show as a
spare disk in the Hardware tree.
•
HP StoreOnce 4700 Backup has one storage enclosure in the base configuration and supports
the addition of up to seven expansion enclosures. The head server node has two small form
factor disks which contain the operating system.
The following installed hardware components are included under the tree hierarchy for each
enclosure. (The head unit on the HP 4700 has only a Drive component.)

Drive: the physical hard disks (see also

•

•

Pools
The number of pools shown depends on the base storage and the number of capacity expansion
kits installed.
There may be up to six pools for each storage cluster, each with its own Volumes sub-element. For
example, Pool C1_P1 relates to the base storage attached to the RAID controller in Slot 1. Pool
C1_P3 relates to the storage from the second 44TB expansion that has been added to this disk
enclosure. On the second disk enclosure, the naming follows the same convention, but it is now
C4, rather than C1, because the storage is connected to the RAID controller in Slot 4.
You will use the Pools and Volumes views to check how parity initialization and RAID expansion
are progressing when you expand storage.
: The Pool contains the Volume information and the number of volumes depends upon the hardware.
For StoreOnce 2700, 4500, and 4700 systems, there is one volume per pool. For HP StoreOnce
B6200 systems there may be multiple volumes per pool. For example, with a storage array
containing 1TB disks there is one volume per pool. With a storage array containing 2TB disks
there are two volumes per pool.
Controllers
This confirms the controller information for the controller card associated with the storage cluster.
The name of the controller links back to the Storage Controller item in the Server section of the
Hardware tree. This item is not included for HP StoreOnce B6200 Backup systems.
The following installed hardware components are included under the tree hierarchy for each storage
controller.
•
I/O cache module
•
Port
•
Super Capacitor
NOTE:
Information about the storage that is integral to the head server and the storage controller
is included under the Server section of the Hardware tree.
