How Ethernet RDMA Protocols iWARP and RoCE Support NVMe over Fabrics

Presented by

David Fair, Chair, SNIA-ESF, John Kim, Director of Storage Marketing, Mellanox

About this talk

NVMe (Non-Volatile Memory Express) over Fabrics is of tremendous interest among storage vendors, flash manufacturers, and cloud and Web 2.0 customers, Because it offers efficient remote and shared access to a new generation of flash and other non-volatile memory storage, it requires fast, low latency networks, and the first version of the specification is expected to take advantage of RDMA (Remote Direct Memory Access) support in the transport protocol. Many customers and vendors are now familiar with the advantages and concepts of NVMe over Fabrics but are not familiar with the specific protocols that support it. This live webcast will explore and compare the Ethernet RDMA protocols and transports that support NVMe over Fabrics and the infrastructure needed to use them. You’ll hear: •Why NVMe Over Fabrics requires a low-latency network •How the NVMe protocol is mapped to the network transport •How RDMA-capable protocols work •Comparing available Ethernet RDMA transports: iWARP and RoCE •Infrastructure required to support RDMA over Ethernet •Congestion management methods
