Abstract: A storage device. The device includes both low-latency persistent memory and higher-latency nonvolatile memory. The persistent memory may be used for write caching or for journaling. A B-tree may be used to maintain an index of write requests temporarily stored in the persistent memory. Garbage collection may be performed in the nonvolatile memory while write requests are being stored in the persistent memory.

Abstract: Example embodiments provide a disaggregated memory appliance, comprising: a plurality of leaf memory switches that manage one or more memory channels of one or more of leaf memory modules; a low-latency memory switch that arbitrarily connects one or more external processors to the plurality of leaf memory modules over a host link; and a management processor that responds to requests from one or more external processors for management, maintenance, configuration and provisioning of the leaf memory modules within the memory appliance.

Abstract: A storage system includes a plurality of solid-state drives (SSDs) in which each SSD is an endpoint of a peer group in which one SSD is a primary SSD of the peer group, or all SSDs are treated as equal peers. Each SSD further includes a host interface port coupled to a host computing device that receives receive input/output (I/O) communications from the host computing device, a peer-interface port coupled to the peer-interface port of each other SSD in the peer group; and a controller coupled to the host interface port and the peer-interface port. The primary SSD controller is responsive to I/O communications received from the host computing device to provide data-protection computations relating to a coordinated data-protection configuration provided by the peer group and to pass the coordinated data-protection configuration information to the controllers of the other end points of the peer group through the peer-interface port.

Abstract: Exemplary embodiments provide a disaggregated memory appliance, comprising: a plurality of leaf memory switches that manage one or more memory channels of one or more of leaf memory modules; a low-latency memory switch that arbitrarily connects one or more external processors to the plurality of leaf memory modules over a host link; and a low-latency routing protocol used by both the low-latency memory switch and the leaf memory switches that encapsulates memory technology specific semantics by use of tags that uniquely identify specific types of memory technology used in the memory appliance during provisioning, monitoring and operation.
