Description

Product Overview

The HP 631679-B21 is a high-performance 1GB Flash Backed Write Cache (FBWC) module designed specifically for the HP Smart Array P-Series controllers. In the demanding world of enterprise data management, protecting your data while maintaining peak performance is critical. This module provides the necessary memory overhead to optimize write operations, significantly reducing latency and increasing the overall throughput of your server's storage subsystem.

Unlike traditional battery-backed write cache (BBWC) solutions, this FBWC module utilizes flash memory technology. This means that in the event of a total power failure, the data currently in the cache is written to non-volatile flash memory, where it can be retained indefinitely. This eliminates the 48-hour limitation of older battery technologies and removes the need for scheduled battery replacement cycles, lowering your total cost of ownership and increasing system uptime.

Key Features and Benefits

Enhanced Data Protection: Uses flash memory to provide indefinite data retention during power loss, ensuring your critical transactions are never lost.
Superior Performance: The 1GB capacity allows the Smart Array controller to queue more write operations, smoothing out performance spikes and improving application responsiveness.
Maintenance-Free Design: By utilizing a capacitor-based power source instead of a chemical battery, you eliminate the need for disposal and periodic replacement of hardware.
Seamless Integration: Designed as a genuine HP ProLiant option, ensuring 100% compatibility and easy installation into supported P-Series controllers.
Increased Efficiency: Optimizes RAID performance, particularly for RAID 5 and RAID 6 configurations where parity calculations can otherwise slow down write speeds.

Ideal Applications

The HP 631679-B21 is an essential upgrade for any business running mission-critical applications on HP ProLiant Gen8 servers. It is particularly beneficial for database management systems where high-frequency write operations occur, virtualized environments where multiple virtual machines share storage bandwidth, and web hosting services that require consistent uptime and data integrity. By adding this 1GB FBWC module to your Smart Array controller, you are investing in the long-term reliability and speed of your enterprise infrastructure.
