Resumen del manual
1 Capacity Upgrade
Introduction
The HP StoreOnce 4500/4700 Capacity Upgrade Kits increase the storage capacity of your HP
StoreOnce Backup system. The following 12–disk expansion kits are available.
•
HP StoreOnce 4500/4700 24TB Capacity Kit (BB881A)
•
HP StoreOnce 4500 48TB Capacity Kit (BB909A)
IMPORTANT:
With the HP StoreOnce 4700, 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 of an expansion kit (BB881A) on the outside and on the
identification labels.
It is very important to connect the first enclosure to the correct RAID controller. 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.
NOTE:
The 48TB Capacity Kit requires StoreOnce software version 3.9.2 or higher and is only
supported with the HP StoreOnce 4500 Backup system. It also includes a Hot Spare disk, which
is in disk bay 12. The 24TB Capacity Kit does not have a Hot Spare disk.
The HP StoreOnce 4500 Backup system supports connection of up to three expansion shelves of
24TB or 48TB capacity.
For the HP StoreOnce 4700 Backup system, one enclosure of 24TB capacity is installed at the
same time as the head unit, which is the base storage of the system. Up to seven further 24TB
expansion shelves may be installed at the same time or added later. A license is required for each
additional Capacity Upgrade and is included with the kit
Planning for the Capacity Upgrade
IMPORTANT:
The addition of storage is an online operation; this means that additional storage
may be added while backups/restores are in progress. However, the new capacity will not be
available until the expansion process completes and there may be a performance impact on
backup/restore operations during the process.
Storage expansion will take several hours to complete, the amount of time will be dependent on
the number of expansion kits being added. It is recommended that all expansion kits are added
in the same operation rather than separately.
Make sure that backup administrators are aware of the expansion process and check to see how
any scheduled jobs, such as backup, replication, or copy, may be affected by decreased
performance.
