HP 274779-001 Raid Cache Memory Battery Pack 3.6V 500mA For Smart Array
The HP 274779-001 is a rechargeable 3.6 V, 500 mAh nickel-metal hydride (NiMH) battery pack designed for use in HP Smart Array RAID controllers with battery-backed write cache (BBWC). It serves as the backup power source for the controller’s cache memory, ensuring that any data stored in cache is preserved during power loss.
As an OEM HP component, this slim, oval-shaped battery module integrates into the Smart Array cache module assembly. In normal operation, it recharges when the system is powered and, in the event of a sudden outage, it provides enough energy to maintain data integrity until power is restored.
The battery pack is a direct replacement for HP part numbers 274779-001 and 307132-001, commonly included in HP’s BBWC kits for ProLiant servers (e.g. DL360, DL380, ML350, etc.). It fits into the cache module bay of compatible HP Smart Array controllers (such as the 6400/641/642 and E200 series) and is supplied as the complete battery assembly.
Features:
- Data-Preserving Backup: Supplies emergency power to the RAID controller’s write cache so that pending write data remains stored safely until power is restored.
- High-Quality NiMH Design: Utilizes a reliable NiMH cell with 500 mAh capacity to meet HP’s performance and longevity requirements; rechargeable for ongoing use.
- OEM Compatibility: Genuine HP battery pack, matching HP P/N 274779-001, 307132-001 – guaranteed fit and performance in HP Smart Array BBWC modules.
- Plug-and-Play Replacement: Ready to install in supported Smart Array controllers (no programming needed); easy swap-in for maintenance or upgrades.
