Hewlett Packard HP SA641/642 128MB DDR Enabler Memory

This product is a memory module designed for use with HP Smart Array controllers, specifically the SA641, SA642, and E200 models. It includes a 128MB battery-backed write cache (BBWC) memory module, which enhances system performance by allowing data to be written to the cache before being transferred to the disk. This module is paired with a 3.6V battery pack assembly (HP 307132-001) to ensure data integrity in the event of a power failure. The modular design allows for easy transport and installation between compatible controllers, making it a versatile upgrade option for systems utilizing these controllers.

The memory module is essential for systems that require reliable and efficient data handling, particularly in environments where data loss could be costly or disruptive. The inclusion of a battery-backed cache ensures that data is not lost during unexpected shutdowns, providing an additional layer of protection for critical information.

The HP 351580-B21 is a specialized component that requires compatibility with specific controller models. It is intended for use in server or high-performance computing environments where data reliability and performance are paramount.
