HP StoreOnce 4700 Backup system
The disks in the head unit of the HP StoreOnce Backup system are used for the operating and
filesystem; they are not used for data storage. Therefore, one 12 disk enclosure which has been
pre-configured before delivery must be connected to the head unit at installation to provide disks
for data storage. A further seven Upgrade Kits may be attached, and they are normally distributed
evenly above and below the head unit.
There are two RAID controller cards in slots 1 and 4. Each has a single high-density SAS connector.
Compatible cables are provided with the Capacity Upgrade Kit; a 2-meter cable to connect the
expansion shelf to the head unit and two half-meter cables for daisy-chaining subsequent shelves.
To connect the first Capacity Kit:
IMPORTANT: The first enclosure is packaged along with the StoreOnce appliance server node
(same pallet), its packaging and identification labels will not carry the part number BB881A. Any
4700 24TB Capacity Kit expansions enclosures will be packed separately and will have part
number BB881A on the outside and on the identification labels.
Connecting the 4700 24TB Capacity Kit to the enclosures incorrectly can result in incorrect behavior
and may result in failure to recognise the attached storage, correction of this issue may result in
the need for support intervention.
