Abstract
A data storage system, including a host server having storage processors, a PCIe fabric, and a GBE fabric, and two or more data storage modules having a bank of DRAM, long-term storage drives, a host interface, including a PCIe interface and a GBE interface, an application specific integrated circuit connected to the host interface, the storage drives, and the DRAM, and a battery, the battery providing power to the DRAM and SSDs in an event of failure of a main power supply. Data streams transmitted from the host server via a PCIe connection of the PCIe fabric are received at the host interface and placed directly in DRAM as a write-back cache operation. In addition, the battery provides the DRAM with non-volatile memory capabilities and the storage modules with portability. A method for arbitration of write requests between the storage processors of the data storage system is also disclosed.
