393847-B21 HP Ni-Mh 4.8V 5000Mah Smart Array P400 And P800 SAS Controller Boards With Battery | Refurbished

The 393847-B21 HP Ni-MH 4.8V 5000mAh Smart Array P400 and P800 SAS Controller Battery is designed to improve the performance and capacity of the Smart Array P400 and P800 SAS controller boards.

The battery is a nickel-metal hydride (Ni-MH) type with a voltage of 4.8V and a capacity of 5000mAh. This battery is specifically designed for use with the Smart Array P400 and P800 SAS controller boards, and it provides backup power to the controller’s cache memory. This means that in the event of a power failure, the battery will keep the controller’s cache memory powered, allowing the controller to write any remaining data to the physical drives, thus protecting data integrity.

In terms of performance, the 393847-B21 battery improves the data integrity and availability of the Smart Array P400 and P800 controllers by providing power to the cache memory during power failure. The battery also helps to increase the overall capacity of the controller by providing power to the cache memory during normal operation, allowing the controller to handle more data and improve performance.

This improves the data integrity and availability of the controller and increases the overall capacity of the controller.

The 393847-B21 HP Ni-MH 4.8V 5000mAh Smart Array P400 and P800 SAS Controller Battery is designed to improve power conservation by providing backup power to the controller’s cache memory in the event of a power failure.

In normal operation, the battery is not actively used, but it acts as a backup power source, ready to provide power to the cache memory in the event of a power failure. This means that the battery is not continuously discharging, which helps to conserve its power.

Additionally, the battery management features of the Smart Array P400 and P800 controllers can help to conserve the power of the 393847-B21 battery. For example, the controllers can be configured to automatically power down the battery if the server is not in use for a certain period of time, or if the battery’s charge level falls below a certain threshold.

The 393847-B21 HP Ni-MH 4.8V 5000mAh Smart Array P400 and P800 SAS Controller Battery has a feature called Low Voltage Detection that helps to protect the battery from damage and prolong its lifespan.

The Low Voltage Detection feature is designed to monitor the voltage level of the battery, and if the voltage falls below a certain threshold, the feature will trigger an alarm and shut down the battery to prevent damage. This can happen when the battery is not properly charged, or if the battery has been in use for an extended period of time.

This feature ensures that the battery is not over-discharged and damaged, and it also helps to prolong the battery’s lifespan by preventing over-discharge. Additionally, it also helps to protect the data integrity of the controller by shutting down the battery when the voltage is too low.
