Product Description
The LSI LSI49571-15 is a specialized battery designed to provide backup power for the cache memory found on LSI RAID controller cards. In the event of a sudden power interruption to the server, this battery ensures that the data residing in the RAID controller's volatile cache is safely written to the attached hard drives or SSDs before power is lost. This process, known as cache write-back, is critical for maintaining data integrity and preventing data loss or corruption. With a voltage rating of 13.5V and a substantial capacitance of 6.4 Farads, this battery is engineered to supply sufficient power for the cache module for a duration adequate to complete the write-back operation. The high capacitance is particularly important for systems that handle large amounts of data or perform write-intensive operations, where the cache plays a significant role in performance and data safety. This LSI cache battery is an essential component for servers and storage systems utilizing LSI RAID controllers that feature write-back cache functionality. Its proper functioning is paramount for data protection strategies, especially in environments where data loss can have severe consequences. The LSI49571-15 ensures that the RAID controller can gracefully handle power failures, thereby enhancing the overall reliability and availability of the storage subsystem.
