Abstract:
A server system is provided that includes one or more compute nodes that include at least one processor and a host memory device. The server system further includes a plurality of solid-state drive (SSD) devices, a local non-volatile memory express virtualization (LNV) device, and a non-transparent (NT) switch for a peripheral component interconnect express (PCIe) bus that interconnects the plurality of SSD devices and the LNV device to the at least one processor of each compute node. The LNV device is configured to virtualize hardware resources of the plurality of SSD devices. The plurality of SSD devices are configured to directly access data buffers of the host memory device. The NT switch is configured to hide the plurality of SSD devices such that the plurality of SSD devices are not visible to the at least one processor of each compute node.
