+ + + Mellanox iSCSI Extensions For RDMA (iSER) Support + + + + + Max + Gurtovoy + + maxg@mellanox.com + + + + + Sagi + Grimberg + + sagig@mellanox.com + + + + + + + + +

Building on the new in-kernel iSCSI initiator stack released + in &os; 10.0 and the recently added iSCSI offload interface, + Mellanox Technologies has begun developing iSCSI extensions + for RDMA (iSER) initiator support to enable efficient data + movement using the hardware offload capabilities of Mellanox's + 10, 40, 56 and 100 gigabit IB/Ethernet adapters.

+ +

Remote Direct Memory Access (RDMA) have been shown to have a + great value for storage applications. RDMA infrastructure + provides benefits such as Zero-Copy, CPU offload, Reliable + transport, Fabric consolidation, and many more. The iSER + protocol eliminates some of the bottlenecks in the traditional + iSCSI/TCP stack, provides low latency and high throughput, and + is well suited for latency aware workloads.

+ +

This work includes a new ICL module that implements the iSER + initiator. The iSCSI stack is slightly modified to support + some extra features such as asynchronous IO completions, + unmapped data buffers, and data-transfer offloads. The user + will be able to choose iSER as the iSCSI transport with + iscsictl.

+ +

The project is in its beta phase. Recent additions + include:

+ + + +

In addition, the iser driver has been and continues + to be thoroughly tested. The test suite includes:

+ + + +

The code is ready for inclusion and will be released under + the BSD license.
