Overview

InfiniBand is an industry standard, channel-based, switched-fabric, interconnect architecture for servers. It is used predominantly in high-performance computing (HPC), and recently has enjoyed increasing popularity for SANs. Its features include high throughput, low latency, quality of service and failover, and it is designed to be scalable.

The InfiniBand architecture specification defines a connection between processor nodes and high performance I/O nodes such as storage devices. InfiniBand forms a superset of the Virtual Interface Architecture (VIP).

Hardware support

The following Mellanox InfiniBand HCAs are supported:

The Unified Target supports iSCSI Extensions for RDMA (iSER) and SCSI RDMA Protocol (SRP) target mode operation on these HCAs.

Protocols
