Abstract
The present disclosure includes methods and systems that share memory located on one PCIe based HBA across other PCIe based HBAs in the system. In addition, the backup battery is effectively shared across multiple PCIe based HBAs in the system. This approach saves significant costs by avoiding the need to have a separate DRAM with its own dedicated battery backup on each HBA board in the system. This also allows the redundant memory and backup batteries to be removed while still retaining the same functionality through the common DDR3 memory chip and battery backup shared across multiple HBAs in the system. The component cost for batteries and memory, management module, board space, and the board manufacturing cost are all reduced as a result.
