What is InfiniBand Switch?

InfiniBand technology works by connecting host-channel adapters(HCAs) to target channel adapters (TCAs). The HCAs tend to be located near the servers’ CPUs and memory, while the TCAs tend to be located near the systems’ storage and peripherals. An Infiniband switch is located between the HCAs and the TCAs, directing data packets to the correct TCA destination based on information that is bundled into the data packets themselves. The InfiniBand switch allows links to create a uniform fabric environment. The InfiniBand switch allows managing packets of information (or data) based on variables, such as service level agreements and a destination identifier.
