The HPE Smart Storage Megacell Battery (Option Part # 727261-B21, Spare Part # 878640-001) is a lithium-ion, low-halogen centralized backup source. It is required to back up the write cache content onto flash memory on HPE Smart Array Gen10 and Gen9 performance RAID (P-class) controllers in case of an unplanned server power loss. This battery also serves as the backup power source for HPE NVDIMMs, allowing data in flight on the DRAM to be moved to the non-volatile NAND flash. It is designed for easy integration and long-lasting performance to maintain data integrity in HPE ProLiant server environments, particularly those with Smart Array controllers. It is sometimes referred to as an Enhanced Megacell 12W battery backed write cache (BBWC) module.
