Abstract:
Distributed storage systems, devices, and associated methods of data replication are disclosed herein. In one embodiment, a server in a distributed storage system is configured to write, with an RDMA enabled NIC, a block of data from a memory of the server to a memory at another server via an RDMA network. Upon completion of writing the block of data to the another server, the server can also send metadata representing a memory location and a data size of the written block of data in the memory of the another server via the RDMA network. The sent metadata is to be written into a memory location containing data representing a memory descriptor that is a part of a data structure representing a pre-posted work request configured to write a copy of the block of data from the another server to an additional server via the RDMA network.

Claim (Index 1):
A method for data replication in a distributed storage system having a plurality of storage nodes interconnected by an remote direct memory access (\u201cRDMA\u201d) network, the storage nodes individually having a processor, a memory, and an RDMA enabled network interface card (\u201cRNIC\u201d) operatively coupled to one another, the method comprising:\n writing, from a first RNIC at a first storage node, a block of data from a first memory at the first storage node to a second memory at a second storage node via a second RNIC interconnected to the first RNIC in the RDMA network; sending, from the first RNIC to the second storage node, metadata representing a memory location and a data size of the written block of data in the second memory via the second RNIC; performing, at the second storage node, modification of a memory descriptor in the second memory according to the metadata, the memory descriptor being a part of a data structure representing a pre-posted work request for writing a copy of the block of data to a third storage node; and upon completion of modifying the memory descriptor, writing, from the second RNIC, a copy of the block of data to a third memory at the third storage node via a third RNIC interconnected to the second RNIC in the RDMA network, thereby achieving replication of the block of data in the distributed storage system without using the processors at the second and third storage nodes.
