Storage controller options
The server ships with an embedded Dynamic Smart Array B140i Controller. This embedded controller is
supported in UEFI Boot Mode only. For more information about the controller and its features, see the
HPE Dynamic Smart Array B140i RAID Controller User Guide on the Hewlett Packard Enterprise website
(http://www.hpe.com/info/smartstorage/docs).
Upgrade options exist for an integrated array controller. For a list of supported options, see the product
QuickSpecs on the Hewlett Packard Enterprise website (http://www.hpe.com/info/qs).
To configure arrays, see the HPE Smart Storage Administrator User Guide on the Hewlett Packard
Enterprise website (http://www.hpe.com/info/smartstorage/docs).
The server supports FBWC. FBWC consists of a cache module and a 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 Smart Storage Battery Pack. This battery pack can support up to 24
devices. Devices in this context refer to the 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.
