2.7.8 InfiniBand host channel adapter
The InfiniBand architecture (IBA) is an industry-standard architecture for server I/O and
inter-server communication. It was developed by the InfiniBand Trade Association (IBTA) to
provide the levels of reliability, availability, performance, and scalability necessary for present
and future server systems with levels significantly better than can be achieved by using
bus-oriented I/O structures.
InfiniBand (IB) is an open set of interconnect standards and specifications. The main IB
specification is published by the InfiniBand Trade Association and is available at the following
location:
http://www.infinibandta.org/
InfiniBand is based on a switched fabric architecture of serial point-to-point links, where these
IB links can be connected to either host channel adapters (HCAs), used primarily in servers,
or to target channel adapters (TCAs), used primarily in storage subsystems.
The InfiniBand physical connection consists of multiple byte lanes. Each individual byte lane
is a four-wire, 2.5, 5.0, or 10.0 Gbps bidirectional connection. Combinations of link width and
byte-lane speed allow for overall link speeds from 2.5 Gbps to 120 Gbps. The architecture
defines a layered hardware protocol, and also a software layer to manage initialization and
the communication between devices. Each link can support multiple transport services for
reliability and multiple prioritized virtual communication channels.
Table 2-28 lists the available InfiniBand adapters.
