Part Number: 405835-001

The HP 512MB BBWC (Battery Backed Write Cache) is a crucial component designed specifically for the Smart Array P400 Controller. Its part number, 405835-001, signifies its unique identification code, allowing users to easily identify and purchase this specific product.

Enhanced Performance and Reliability

The 512MB BBWC plays a critical role in enhancing the performance and reliability of the Smart Array P400 Controller. It acts as a cache module, improving the overall read and write speeds of the controller, resulting in faster data transfers and improved system responsiveness.

Optimized Write Caching

One of the key benefits of the 512MB BBWC is its optimized write caching capability. With a battery-backed cache, it allows the controller to temporarily store write operations in memory before writing them to disk. This significantly reduces latency and improves overall system performance by avoiding delays caused by the slower disk writes.

Data Protection and Integrity

The battery-backed feature of this module ensures that data in the write cache is protected in case of power loss or system failure. It provides a reliable power source to retain cached data until power is restored, preventing any potential data loss or corruption. This feature is particularly crucial for critical applications or databases that rely on uninterrupted data integrity.

Increased System Efficiency

The 512MB BBWC offers several features that contribute to increased system efficiency:

Reduced Disk I/O Operations

By utilizing write caching, the BBWC reduces the number of disk I/O operations required to complete write operations. This results in reduced wear and tear on the disks, prolonging their lifespan and improving overall system efficiency.

Improved RAID Performance

The Smart Array P400 Controller with the 512MB BBWC provides enhanced RAID performance. By accelerating write operations, it minimizes the time required to rebuild RAID arrays or perform other disk-intensive tasks. This allows for quicker recovery in case of disk failure and reduces the risk of data loss.

Easy Installation and Compatibility

The 512MB BBWC is designed for easy installation and compatibility with the Smart Array P400 Controller. It can be easily plugged into the controller without requiring any additional tools or complex configurations. The part number, 405835-001, ensures that users can confidently select the correct module for their specific controller model.
