The HP 631679-B21 is a 1GB Flash Backed Write Cache with Battery designed for the HP P-Series SA Gen8 Controller. In this article, we will take a closer look at what the HP 631679-B21 is, how it works, and what benefits it offers.
Flash Backed Write Cache with BatteryThe HP 631679-B21 is a Flash Backed Write Cache with Battery, which means that it uses a combination of flash memory and battery power to store data. The flash memory provides a fast, non-volatile storage medium that can hold data even if power is lost, while the battery provides backup power to ensure that data is not lost in the event of a power outage or system failure.
The flash memory in the HP 631679-B21 is used to store write cache data, which is data that has been written to the cache but has not yet been transferred to the storage devices. This data is held in the cache temporarily, allowing it to be written to disk in a more efficient manner. The battery provides backup power to the flash memory, ensuring that data is not lost in the event of a power failure.
Benefits of HP 631679-B21The HP 631679-B21 offers several benefits, including improved system performance, increased reliability, and enhanced data protection.
Improved System PerformanceThe HP 631679-B21 can significantly improve system performance by reducing the amount of time it takes to write data to disk. By temporarily storing data in the cache, the server can quickly write data to the cache and then transfer it to the storage devices at a later time. This helps to reduce the amount of time it takes to write data to disk, which can improve overall system performance.
Increased ReliabilityThe HP 631679-B21 can also help to increase system reliability by providing a backup power source for the cache. In the event of a power outage or system failure, the battery can provide backup power to the cache, ensuring that data is not lost. This can help to prevent data corruption and other issues that can occur when data is lost.
Enhanced Data ProtectionThe HP 631679-B21 also provides enhanced data protection by using flash memory to store write cache data. Flash memory is a non-volatile storage medium that can hold data even if power is lost. This helps to ensure that data is not lost in the event of a power outage or system failure.
Compatibility
The HP 631679-B21 is designed to be compatible with the HP P-Series SA Gen8 Controller. It is important to note that the HP 631679-B21 is not compatible with other HP controllers or other server brands.
