Storage Controller Installation Guidelines; Installing The Hpe Smart Storage Battery - HP APOLLO 2000 User Manual

The node 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.
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 node 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 node 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

To maintain optimal thermal conditions and efficiency, Hewlett Packard Enterprise recommends the following
guidelines:
• Install one storage controller per node.
• The HPE H240/H241 host bus adapter or HPE P440/P441 Smart Array controller can be installed in slot 1
or slot 2.
IMPORTANT:
The HPE Apollo r2800 Chassis does not support nodes using the HPE Dynamic Smart Array B140i
Controller or the HPE P840 Smart Array Controller. Hewlett Packard Enterprise recommends
installing an HPE H240 Host Bus Adapter or HPE P440 Smart Array Controller.
• The HPE P840 Smart Array controller can only be installed in slot 2 of the FlexibleLOM 2U node riser cage
assembly (PN 798184-B21)
Determine if there are thermal requirements for the option. For a list of options that have thermal limitations,
see "Thermal limitations."
For more information on the riser board slot specifications, see "PCIe riser board slot definitions."
For information on drive bay mapping in the HPE Apollo r2800 Chassis and the factory default configuration,
see "Drive bay mapping for the HPE Apollo r2800 Chassis."
For more information about product features, specifications, options, configurations, and compatibility, see the
product QuickSpecs on the Hewlett Packard Enterprise website.
