HPE BBWC & FBWC Backup Battery Options for Older Smart Array Controllers

HPE Smart Array controllers use different backup-power technologies and battery assemblies depending on controller generation, cache architecture and server platform. This product category covers BBWC and FBWC backup battery options for older and legacy HPE Smart Array controllers.

Because HPE used different battery modules, cable assemblies and battery capacities across Smart Array generations, the correct replacement must be matched to the controller and server configuration. Common HPE part numbers include 398648-001, 462976-001, 462969-B21, 871265-001 and 878640-001, among others.

HPE Smart Array BBWC & FBWC Battery Features

• Backup-power solutions for compatible HPE Smart Array controllers
• Supports Battery-Backed Write Cache (BBWC) and Flash-Backed Write Cache (FBWC) architectures
• Available across multiple generations of HPE P-Series Smart Array controllers
• Multiple spare and option part numbers available depending on controller and server
• Designed to protect cached write data during unexpected power interruption

Common HPE Smart Array Battery Part Numbers

HPE 398648-001 BBWC Battery

The 398648-001 battery module is documented by HPE for Smart Array P400 and P800 SAS controller boards with Battery-Backed Write Cache. HPE specifies this module as a Ni-MH battery with an integrated charger, rated at 4.8V and 5000mAh.

HPE 462976-001 BBWC Battery

The 462976-001 battery module is designed for compatible Smart Array P212, P410 and P411 SAS controller boards with BBWC. HPE specifies a 4.8V, 650mAh Ni-MH battery module with integrated charger.

HPE 462969-B21 P-Series Battery

462969-B21 is identified by HPE PartSurfer as the HPE 650-mAh P-Series Battery. It belongs to the older P-Series Smart Array battery ecosystem and should be matched against the exact controller and cache module before replacement.

HPE 871265-001 and 878640-001 Smart Storage Batteries

Later HPE Smart Array generations introduced Smart Storage Battery and enhanced Megacell designs. HPE documents 871265-001 as an Enhanced Megacell 12W BBWC module and 878640-001 as a 12W Megacell Smart Storage Battery Pack rated at 7.2V.

BBWC vs FBWC

Battery-Backed Write Cache (BBWC) uses a battery-backed cache architecture to retain cached data during a power interruption. Flash-Backed Write Cache (FBWC) uses battery or capacitor-backed power to move protected cache contents to non-volatile flash memory.

The required battery therefore depends on the Smart Array controller's cache architecture. A BBWC battery should not be assumed to be interchangeable with an FBWC Smart Storage Battery simply because the connectors appear similar.

Compatibility

Compatibility is controller- and platform-specific. HPE documentation associates the battery families in this category with Smart Array controllers including P400, P800, P212, P410, P411 and other compatible P-Series and Smart Array configurations.

• HPE Smart Array P400 and P800
• HPE Smart Array P212
• HPE Smart Array P410
• HPE Smart Array P411
• Selected P-Series Smart Array controllers
• Selected HPE ProLiant Gen8 and Gen9 configurations

Important: Exact compatibility should be confirmed using the Smart Array controller model, cache module, server model and existing battery part number before ordering.

Applications

• Replacement of failed Smart Array BBWC batteries
• Replacement of degraded cache backup batteries
• Legacy HPE ProLiant server maintenance
