Dell UF302 PERC 5i 7WH 3.7V Lithium-ion Battery Backup Unit

Product Description

The Dell UF302 is a specialized battery backup unit designed to complement Dell's PERC 5i series RAID controllers. Its primary function is to supply auxiliary power to the RAID controller's onboard cache memory in the event of an unexpected loss of main system power. This temporary power source is crucial for the integrity of data being processed by the RAID array. Without this backup, data residing in the controller's volatile cache could be lost or corrupted during a power failure, leading to potential system instability and data loss. Utilizing advanced Lithium-ion technology, the UF302 offers a reliable and efficient power solution with a capacity of 7 Watt-hours at a nominal voltage of 3.7V. This capacity is sufficient to allow the RAID controller to perform essential operations, such as flushing the contents of its cache to the persistent storage drives, before the system completely shuts down. This process is vital for maintaining the consistency and reliability of the RAID volume, especially in environments where data integrity is paramount. Proper installation and maintenance of the UF302 battery are key to ensuring its effectiveness. It typically connects directly to the PERC 5i controller card. Over time, like all batteries, its performance may degrade, and periodic checks or replacements might be necessary to guarantee uninterrupted protection. This component is indispensable for servers and workstations utilizing PERC 5i controllers that handle critical data workloads.
