Storage Controller Installation Guidelines; Installing A Storage Controller And Fbwc Module Options - HP HPE ProLiant ML30 Gen9 User Manual

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 an 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.
CAUTION: The cache module connector does not use the industry-standard DDR3
mini-DIMMs. 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.
CAUTION: To prevent a server malfunction or damage to the equipment, do not add or
remove the battery pack while an array capacity expansion, RAID level migration, or stripe size
migration is in progress.
CAUTION: After the server is powered down, wait for 30 seconds, and then check the amber
LED before unplugging the cable from the cache module. If the amber LED flashes after 30
seconds, do not remove the cable from the cache module. The cache module is backing up
data. Data will be lost if the cable is detached when the amber LED is still flashing.

Storage controller installation guidelines

Storage controllers may be installed in slot 1 or 4. Hewlett Packard Enterprise recommends installing a
storage controller in PCIe slot 4 for optimal performance.
An optional front PCI fan must be installed if any PCI cards are installed in the system.
Storage controllers additionally require the appropriate optional cable to connect to storage devices.
