Product Information of HP 405148-B21 512MB
The HP 405148-B21 512MB Battery Backed Write Cache Upgrade is a storage accessory designed for the Smart Array P400 controller. It enhances the storage performance of the server by providing a battery-backed write cache upgrade. This upgrade is essential for high-performance computing applications that require fast and reliable data transfer rates.
Smart Array P400 Controller
The Smart Array P400 controller is a high-performance RAID controller designed for servers. It supports up to eight SAS or SATA drives, providing high-speed data transfer rates for demanding applications. The controller supports RAID levels 0, 1, 5, 6, 10, 50, and 60, providing data redundancy and fault tolerance. It also supports hot-plug drives, making it easy to add or remove drives without shutting down the server.
Battery Backed Write Cache Upgrade
The HP 405148-B21 512MB Battery Backed Write Cache Upgrade provides a battery-backed write cache upgrade for the Smart Array P400 controller. This upgrade enables the controller to cache write data in memory before writing it to the disk. Caching write data in memory speeds up the write process and enhances the performance of the server. The battery-backed cache ensures that the write data is not lost in case of a power failure or system crash.
512MB Cache Size
The HP 405148-B21 512MB Battery Backed Write Cache Upgrade comes with a cache size of 512MB. This size is sufficient for most applications and ensures that the controller can cache a large amount of write data in memory. The size of the cache can be adjusted based on the needs of the application. However, increasing the cache size may require a larger battery backup to ensure data integrity in case of a power failure.
