Abstract: Systems and methods are provided for expanding the available memory of a storage controller. The systems and methods utilize a PCIe memory controller connected to the backend interface of the storage controller. Memory of the PCIe memory controller is memory mapped to controller memory of the storage controller. The PCIe connection allows the storage controller to access the memory of the PCIe memory controller with latencies similar to that of the controller memory.

Abstract: Data storage systems and methods for storing data are described herein. An intermediate storage system is coupled with a High Performance Computing (HPC) system. A plurality of burst engines of the intermediate storage system are directly connected to compute nodes of the HPC. The burst engines are operative to receive file level data from the compute nodes at data transfer rates that at least match to the burst mode output rate of the compute node. The burst engines store the data to high bandwidth storage devices of the intermediate storage system at a data rate that at least matches the burst output rate of the compute node. During a compute phase of the compute node, data is replayed from the intermediate storage devices to a primary storage system at a lower data transfer rate.

Abstract: System and methods for managing I/O write requests of host systems to physical storage. A storage subsystem includes a plurality of storage devices where each storage device is configured to provide data storage. At least a pair of redundant controllers is connected to the plurality of storage devices for executing the I/O write requests from the host systems. A received I/O write request is initially saved in a controller memory of one of the controllers and mirrored in controller memory of the other controller. In one embodiment, the I/O write request is transferred to a flash memory device for subsequent transfer to the storage devices. Once transferred to the flash memory device, the I/O write request may be flushed from the controller memories. The I/O write request may then be transferred to the storage devices from the flash memory device as a background operation.
