Description

The InfiniHost is Mellanoxs second generation InfiniBand architecture host or target channel adapter (HCA/TCA) silicon. The chip architecture unleashes 10Gb/s data center performance, and is designed to saturate dual 4X links. InfiniHost is a single chip dual-port 10Gb/s InfiniBand host channel adapter with a PCI-X interface and integrated physical layer serializer/deserializer (SerDes) interfaces. The device features an HCA core that is capable of full wire speed transmissions over InfiniBand links. The core features a full hardware implementation of the InfiniBand architecture memory protection and translation tables, as well as, hardware transport. This drastically reduces CPU overhead to enable the host processor to spend its cycles on applications and not on communications InfiniHost Feature Set The InfiniHost advances performance, scalability, interoperability and the cost effectiveness of InfiniBand based copper and fiber fabrics. InfiniHost devices are designed to be fully compatible with the InfiniBand Trade Associations (IBTA) 1.0a specification, and are interoperable with other devices designed to meet the specification. Developers can combine InfiniHost, InfiniBridge and InfiniScale devices to enable large 4X InfiniBand sub-nets. The architecture includes fast external DDR memory support for up to 4GB of DDR memory and supports an industry leading number of Queue Pairs (QPs). For TCA implementations, an Application Specific Programmable Packet Engine (ASPPE) and internal InfiniRISC processor allows application specific processing. In routing applications, the DDR memory improves performance by enabling packet payloads to be stored and forwarded directly from the local HCA memory, not system memory. Integrated Physical Layer SerDes The InfiniHost device integrates eight 2.5Gb/s SerDes in a single 580-pin package. This high-level of integration reduces power consumption, system cost, and PCB size, simplifies board designs, and eliminates all external physical layer parts needed to connect to either 2.5 or 10 Gb/s copper or fiber optical links.
