HPE 012695-001 4.8V 5000mAh Ni-MH Smart Array Controller Refurbished

When managing a server, ensuring data integrity and system reliability is paramount. Hewlett Packard Enterprise (HPE) offers a solution to enhance these aspects through its 012695-001 Battery Controller.it is 4.8v. This component is specifically designed for Smart Array P400 and P800 SAS Controller Boards, equipped with a Battery Backed Write Cache (BBC). This guide will delve into the specifics of the HPE 012695-001 Battery Controller, breaking down its features, benefits, and how it integrates with server infrastructure in simple English.

Before we explore the battery controller itself, let's understand what Battery Backed Write Cache is and why it's crucial for server operations. A Write Cache is a form of temporary data storage (cache) used to collect write commands sent to the server, storing them until they can be permanently written to the server's storage disks. The "Battery Backed" part means that this cache is protected by a battery backup. In the event of a power loss or system failure, the battery ensures that the data in the cache isn't lost but instead can be safely written to the disk once the system is back online. This significantly reduces the risk of data loss and corruption.

The HPE 012695-001 Battery Controller is a specific model of a battery backup unit designed for use with HPE's Smart Array P400 and P800 SAS (Serial Attached SCSI) Controller Boards. These controller boards are critical for managing the data flow between the server's processor and its storage devices. The battery controller's main job is to provide power to the Write Cache in case of an unexpected power outage, ensuring that any data temporarily stored in the cache can be safely written to the storage disks later.

Servers require a constant power supply to operate. However, in the event of a power failure or fluctuation, ongoing transactions and data-writing processes can be abruptly interrupted, leading to potential data loss or corruption. To mitigate this risk, servers use batteries as part of their write cache system.

BBC is a mechanism that uses a battery to maintain the power supply to the cache memory of a server's storage controller. The cache memory temporarily stores write operations before they are permanently written to the disk. If the server loses power, the battery ensures that the data in the cache can still be written to the disk once power is restored, preventing data loss.

The HPE 012695-001 battery controller is integral to the operation of BBC in servers with Smart Array P400 and P800 controller boards. Here's how it supports server operations:

By providing backup power to the write cache, the HPE 012695-001 ensures that all write operations can be completed even in the event of a power failure. This dramatically reduces the risk of data loss and corruption.

The write cache allows for the aggregation of write operations, which can be written to the disk in a more efficient manner. This can significantly improve server performance, as the storage array can handle write requests more quickly and efficiently.

Servers equipped with a battery-backed write cache, supported by batteries like the HPE 012695-001, are more reliable. They can ensure data integrity and system uptime even in unstable power conditions, making them ideal for critical applications.
