Remote Direct Memory Access (RDMA) is a computer networking technology usually implemented over high-speed, low-latency networks (aka fabrics) which allows for direct access to a remote host's memory, dramatically reducing latency and CPU overhead.

Short for remote direct memory access (), a communications technique that allows data to be transmitted from the memory of one computer to the memory of another computer without passing through either device s CPU, without needing extensive buffering, and without calling to an operating system kernel.RDMA is a response to increasing demands for network speed.

RDMA over Converged Ethernet (RoCE) is a network protocol that allows remote direct memory access (RDMA) over an Ethernet network. It does this by encapsulating an IB transport packet over Ethernet. There are two RoCE versions, RoCE v1 and RoCE v2. RoCE v1 is an Ethernet link layer protocol and hence allows communication between any two hosts in the same Ethernet broadcast domain.

I would like to have some low-latency computation on a pool of shared memory, with remote atomic operations. I know RDMA is the way to go. On each node I would register a memory region (and protection domain) for data sharing. The online RDMA examples often focus at a single connection between a single-threaded server and a single-threaded.

All this copying is slow, and if RDMA could speed it up, the datacenter would be used more effectively. Everyone wants a piece of that amazing speed. So this has created a wave of demand for RDMA, except not on IB, and not in a form where one user could easily disrupt some other user.

The pNIC also has to have RDMA enabled or virtual NIC won’t be able to leverage RDMA but fall back to SMB (Multichannel only) instead of SMB Direct. Likewise, RDMA has to be enabled on the vNIC as well. So don’t forget, RDMA must be enabled on both the pNIC and the vNIC for this to work.

RDMA (Remote Direct Memory Access) A communications protocol that provides transmission of data from the memory of one computer to the memory of another without involving the CPU.InfiniBand, Virtual Interface (VI) and RDMA Over IP are all forms of RDMA. Implemented in hardware on the network adapter (NIC), RDMA techniques have been developed to accommodate the ever-increasing network speeds.

RDMA is a technology in this space which can greatly contribute to overall performance gains in various implementations. In this blog I want to talk about my experience of RDMA over Converged Ethernet (RocEv2) within a Microsoft Storage Spaces Direct deployment and an alternative option for RDMA over Ethernet, iWARP. What is RDMA?

Introducing a new way to enable high-speed data transfers over an Ethernet network with minimal CPU involvement RDMA (Remote Direct Memory Access) is growing in popularity in Linux and Windows systems as a way to transfer large amounts of data with low latency and minimal involvement from the CPU. However RDMA InfiniBand drivers in FreeBSD were not updated, requiring users to create or port.
