ThinkSystem RAID 930-24i Adapter Installation and User Guide
1st Edition Chapter 3: ThinkSystem RAID 930 Cache Data Protection
Chapter 3: ThinkSystem RAID 930 Cache Data Protection
The ThinkSystem RAID 930-24i adapter supports data retention by using NAND flash memory down on the adapter,
backed up by a ThinkSystem RAID 930 SuperCap.
The ThinkSystem RAID 930 SuperCap is a super-capacitor pack that provides power for the backup of your data in case
of host power loss or server failure. The SuperCap is connected to the controller remotely by cable. The data is backed
up to the NAND flash memory available on the adapter.
In the event of host power loss or server failure, any data available in the cache is offloaded to the on-board NAND
memory. During this process, the necessary components needed for offload are powered by the SuperCap pack.
CAUTION Disconnect the computer from the power supply and from any
networks, or you risk damaging the system or experiencing electrical
shock.
CAUTION Plugging the SuperCap into a powered adapter (hot plugging) is not
supported. This action might damage the SuperCap and the adapter.
Hot plugging the SuperCap voids the warranty support.
ATTENTION To avoid the risk of data loss, back up your data before you change
your system configuration.
To install the SuperCap and connect it to the adapter, follow these steps.
1. Insert the SuperCap into the holder. The location used to store the SuperCap is different for each system.
Consult system documentation for more information.
2. Connect the SuperCap to the adapter. Insert the module interface cable connector (larger connector) into the
SuperCap cable connector. Insert the board interface cable connector (smaller connector) into the J3 connector
on the adapter. Align the cable connectors to make sure they are connected correctly.
3. Install the adapter. Install the adapter in a PCIe slot on the motherboard. Press down gently, but firmly to seat the
board correctly in the slot. Secure the controller to the computer chassis with the bracket screw.
