Lenovo - ServeRAID M5100 Series Battery Kit - RAID controller battery backup unit - Li-Ion - 81Y4508

In business systems, reliability is one of the most important factors besides performance and manageability. For this reason, the use of original components is recommended in many cases. Under the Lenovo part number (FRU) 81Y4508, you will receive the general overhauled Battery Backup Unit (BBU) to ensure a high failure and data security.

By using the Lenovo 81Y4508 ServeRAID M5100 Series Battery Kit, the RAID controller is still powered by a power failure or in similar situations. The battery based on the lithium-ion technology thus prevents the contents of the cache memory from being lost. As soon as the power supply is restored, the data is available without any restrictions.

To check the compatibility of the BBU with your server, you can use the Lenovo FRU 81Y4508 as usual. Basically, the ServeRAID M5100 series is supported, which would be compatible with the Lenovo X3300 M4 Server. However, please check this before buying to ensure a smooth operation.
