A method, computer program product, and computer system for exposing, by a user block layer of a computing device, a storage device as a block device to an application associated with an IO request. A Non-Volatile Memory Express (NVMe) protocol layer of the computing device may expose a NVMe storage device associated with the IO request to the user block layer. A NVMe-over-RDMA layer of the computing device may create a NVMe RDMA queue for the IO request to be processed.

System and method for user space NVMe-over-RDMA host library

A method is disclosed comprising: instantiating a first plurality of type-1 network sockets on a source computing system, each of the type-1 network sockets having a first queue depth; instantiating a second plurality of type-2 network sockets on the source computing system, each of the type-2 network sockets having a second queue depth that is greater than the first queue depth; transitioning the source computing system into a first state, the first state being one in which data replication messages are transmitted by the source computing system to a target computing system by using both the type-1 and type-2 network sockets; transitioning the source computing system from the first state into a second state, the second state being one in which data replication messages are transmitted by the source computing system to the target computing system by using the type-2 network sockets.

Sockets for shared link applications

A method, computer program product, and computing system for deploying a kernel driver extension in a kernel of a storage processor communicatively coupled to one or more non-volatile memory express (NVMe) devices. The kernel driver extension may be communicatively coupled with a standard NVMe kernel driver deployed in the kernel of the storage processor. One or more input/output (I/O) operations may be performed on the one or more NVMe devices via the standard NVMe kernel driver and the kernel driver extension.
