The HP 512MB Flash Backed Write Cache (FBWC) is a storage technology used in servers to improve performance and data integrity. It is designed to work with the HP Smart Array P420 controller and provides a reliable, high-speed cache for write operations.
Overview of the HP Smart Array P420 ControllerThe 633540-001 HP Smart Array P420 controller is a RAID controller used in HP ProLiant servers. It provides hardware RAID support for SATA and SAS drives and offers several advanced features, such as online capacity expansion and RAID migration. The P420 controller also supports advanced data protection features, such as RAID 6 with ADG, which provides protection against multiple drive failures.
The 633540-001 P420 controller has a cache module that is used to improve write performance. When a write operation is requested, data is first written to the cache module, and then to the disk. This improves performance by reducing the amount of time it takes to write data to the disk.
However, if power is lost or the server crashes before the data can be written to the disk, the data in the cache is lost, which can result in data corruption or loss. To prevent this, the P420 controller uses a flash-backed write cache module.
Overview of the HP 512MB Flash Backed Write CacheThe 633540-001 HP 512MB Flash Backed Write Cache (FBWC) is a plug-in module that is designed to work with the HP Smart Array P420 controller. It provides a reliable, high-speed cache for write operations and is designed to protect against data loss in the event of a power failure or system crash.
The FBWC module is a small circuit board that plugs into the P420 controller. It contains a high-speed cache memory and a flash memory module. The cache memory is used to temporarily store data that is waiting to be written to the disk, while the flash memory module is used to store a copy of the data in case of a power failure or system crash.
The flash memory module is non-volatile, which means that it does not require power to retain data. This ensures that data is not lost even if power is lost or the system crashes.
The HP 512MB FBWC module is compatible with HP ProLiant servers that use the P420 controller. It is easy to install and requires no additional software or configuration.
Benefits of the HP 512MB Flash Backed Write CacheThe 633540-001 HP 512MB FBWC module provides several benefits to server administrators and IT managers. These benefits include:
Improved write performance: The FBWC module provides a high-speed cache for write operations, which can significantly improve the performance of the server. By caching write operations in memory, the module reduces the amount of time it takes to write data to the disk.
Data protection: The FBWC module is designed to protect against data loss in the event of a power failure or system crash. By storing a copy of the data in flash memory, the module ensures that data is not lost if power is lost or the system crashes.
Easy to install: The FBWC module is easy to install and requires no additional software or configuration. Simply plug the module into the P420 controller, and it is ready to use.
Compatibility: The HP 512MB FBWC module is compatible with a wide range of HP ProLiant servers that use the P420 controller. This makes it a versatile storage solution for organizations that use HP servers.
Finally, the 633540-001 HP 512MB Flash Backed Write Cache (FBWC) is a reliable and high-performance storage technology that is designed to work with the HP Smart Array P420 controller. It provides a fast cache for write operations and is designed to protect against data loss in the event of a power failure or system crash.
