GigaRAID/FT Model 2300 Battery Backup Unit with Three-Year Standard Warranty.


GigaRAID/FT RAID 0, 1, 0/1, 3, 5 Disk Arrays are designed specifically for I/O-intensive applications in mission-critical environments. GigaRAID/FT provides superior capacity, fault tolerance and performance in a compact deskside or rackmount enclosure. Housing up to 20 drives, GigaRAID/FT offers up to 80GB of storage capacity. For fault tolerance, the system supports redundant, customer-replaceable RAID controllers, power supplies and hot spare disk drives, as well as a battery backup unit for cache memory.

The GigaRAID/FT's Model 2300 Battery Backup Unit (BBU) is required for the storage-system cache and may be installed in a Model 2200 to upgrade to a Model 2300. In the event of a power outage, the BBU allows the Storage Processor (SP) to shut down the storage system in an orderly way. The BBU can provide up to 60 seconds of power, which is sufficient for the SP to empty its cache by writing data to the physical disk units. To conserve power, the SP shuts down all unnecessary disk drive modules while emptying the cache. Once cache data is safely stored on the physical disk units, the SP disables the BBU to preserve the life of its internal power cells. When power returns, the BBU recharges its cells automatically. The BBU may be installed or removed while the disk array storage system is running.
