Controller options

The server ships with an embedded HP Dynamic Smart Array B140i Controller. For more information about
the controller and its features, see the HP Dynamic Smart Array B140i RAID Controller User Guide on the HP
website (http://www.hp.com/go/smartstorage/docs).
Upgrade options exist for an integrated array controller. For a list of supported options, see the product
QuickSpecs on the HP website (http://www.hp.com/go/qs).
To configure arrays, see the HP Smart Storage Administrator User Guide on the HP website
(http://www.hp.com/go/smartstorage/docs).
The server supports FBWC. FBWC consists of a cache module and an HP Smart Storage Battery Pack. The
DDR cache module buffers and stores data being written by an integrated Gen9 P-series Smart Array
Controller.
This server supports the 96-W HP Smart Storage Battery Pack. This battery pack can support up to 24
devices. Devices in this context refer to the HP Smart Array Controller or NVDIMM associated with the cache
module.
The battery pack might have a low charge when installed. If the battery does have low charge, a POST error
message appears when the server is powered up, indicating that the battery pack is temporarily disabled.
No action is necessary. The internal circuitry automatically recharges the batteries and enables the battery
pack. When the system is powered on this process might take approximately 2 hours.
If a system power failure occurs, a fully charged battery pack provides power for up to 150 seconds. During
that interval, the controller transfers the cached data from DDR memory to flash memory, where the data
remains indefinitely or until a controller retrieves the data. The data protection and the time limit also apply
if a power outage occurs. When power is restored to the system, an initialization process writes the
preserved data to the storage drives.
CAUTION:
Do not use the controller with cache modules designed for other controller models, because the
controller can malfunction and you can lose data. Also, do not transfer this cache module to an
unsupported controller model, because you can lose data.
