RAID MegaRAID LSIiBBU08 LSI-IBBU08

LSI MegaRAID LSIiBBU08 Battery Backup Unit

The LSI MegaRAID LSIiBBU08 is an intelligent battery backup unit (iBBU) for LSI MegaRAID 6Gb/s SAS RAID controllers. It protects the integrity of the cached data on the RAID controller in case of a complete or brief power failure, and it is an inexpensive alternative to a UPS or a second level of protection when used together with one.

The unit is based on lithium-ion cell technology and can either mount directly on the controller through a board-to-board connector or work remotely over a 12-inch cable.

Key features

• Protects the controller cache - During a power failure the unit preserves the data in the RAID controller cache for up to 48 hours, depending on the retention time selected.
• Lithium-ion technology - A rechargeable battery pack rated 3.7V, 1.59Ah and 5.9Wh, built on a lithium-ion cell.
• Direct mounting on the controller - The daughtercard has a J1 connector that attaches straight to the 9260-4i, 9260-8i, 9261-8i, 9280-4i4e and 9280-8e controllers and is secured with screws and standoffs.
• Remote mounting - The unit can also be placed elsewhere in the chassis and connected over a 12-inch cable through the J2 connector. On some models this also requires a remote interposer board, sold separately in a Remote Battery Kit.
• Fits the 92xx family - Suitable for MegaRAID SAS 9260, 9261 and 9280 controllers, including the 9260-16i, 9280-16i4e and 9280-24i4e in remote mounting.
