Battery modules increase the data security of your servers

The loss of mission critical data due to unexpected disruptions and failures can have serious consequences and should be avoided at all costs. Modern IT infrastructures offer a range of protective options to ensure a high level of security against events such as power failures. Server systems can often be equipped with multiple redundant power supplies to prevent system downtime due to the failure of individual modules. In addition, the use of an UPS (Uninterruptible Power Supply) provides protection against power failures. This is essentially a device with an integrated battery that can ensure the operation of connected servers and network devices for a certain period of time in the event of a power failure.

If a power failure occurs despite these measures, it does not necessarily result in data loss. Storage controllers, which are used to manage disk space and control read and write accesses, often support the connection of battery modules to maintain the controller's buffer memory in the event of a power failure. These components perform a similar function in server solutions from various manufacturers such as HPE, Dell, Lenovo and Fujitsu, although they are sometimes referred to by different names:

• Battery Backup Unit (BBU)
• Capacitator Pack
• Storage Battery Unit
• Battery Pack

Effective protection for your database servers with compatible battery modules

The battery modules are installed inside the server chassis using model-specific holders and connected to the system's RAID (Redundant Array of Independent Disks) controller using appropriate cables and connectors. This allows the integrated batteries to be charged during normal server operation and is a critical factor in maintaining data integrity in critical cases. Particularly with applications such as complex databases, corrupted or missing data can be a significant problem, as it is often not immediately detected and restoring from a backup results in the loss of later changes.

Battery modules protect controller cache data during disruptions

To optimise disk management, storage controllers often use a cache to buffer data that has not yet been written to the server's hard disks. This is usually volatile memory, comparable to main memory, that is erased when power is removed. This data would be lost in the event of an unexpected system shutdown due to a power failure. This can be avoided by installing a compatible battery module to power the controller cache until the power is restored. Depending on the capacity of the batteries installed, data can be retained for several hours. As battery cells are subject to wear and tear and potential capacity is reduced, battery modules should be checked and replaced with appropriate spare parts as standard server maintenance. In addition, maintenance-free solutions are available for newer systems based on capacitors for the power supply and non-volatile NAND flash memory, similar to SSD hard drives (Solid State Drive). With the right accessories, server and storage systems of almost all generations can be protected against unexpected events.
