078-000-092-07 BBU for Dell EMC VNX5200, VNX5400, VNX5600, VNX5800, and VNX7600
The EMC VNX BBU (Battery Backup Unit) with part number 078-000-092-07 is a critical component in the VNX2 series storage systems, such as the VNX5200, VNX5400, and VNX5600. Its primary function is to provide temporary power to the storage processors in the event of a power outage, ensuring that any data in volatile memory (cache) is safely written to non-volatile storage before the system shuts down. This prevents data loss and maintains system integrity during unexpected power interruptions.
The 078-000-092-07 BBU uses advanced lithium-ion battery technology and is designed for seamless integration with VNX2 arrays. It has identical specifications to the 078-000-132-00, with the part number difference likely reflecting a change in supplier or minor component variation as dictated by EMC’s bill of materials (BOM) process. Despite these variations, both BBUs deliver the same rated power output and performance, making them interchangeable within the VNX2 system family.
This BBU plays an essential role in safeguarding data and ensuring system reliability, particularly in environments where uninterrupted data access is critical.
