Mellanox InfiniBand HCA Overview One of the features of an InfiniBand fabric is that individual components can contain an InfiniBand host channel adapter (HCA) or a mezzanine HCA. The components that contain HCAs are visible and manageable parts of your InfiniBand fabric. The HCA may be an integrated circuit embedded on the circuit board of a component (such as a storage array controller) or it can be a PCI card that is installed in a server.
HP 4X DDR InfiniBand Mezzanine HCAs (448262-B21 and 410533-B21) The HP 4X DDR InfiniBand mezzanine host channel adapters (HCAs) for HP BladeSystem c-Class is based on the ConnectX technology developed by Mellanox. These HCAs are only supported by HP in HP Cluster Platform configurations. The features for the HP 4X DDR InfiniBand dual-port mezzanine HCA include: • • • • • • • Low latency and high bandwidth PCI Express revision 2.0x8 support 20 Gb/sec InfiniBand port IBTA version 1.
Mellanox ConnectX IB InfiniBand HCAs (448397-B21 and 483514-B21) The Mellanox ConnectX IB InfiniBand host channel adapters (HCAs) provide low-latency and highbandwidth for server and storage clustering applications. The ConnectX IB InfiniBand HCA features include: • • • • • • 1.
Mellanox InfiniHost III Ex Dual-Port InfiniBand HCAs with PCI Express x8 (483513-B21, 409376-B21, 380298-B21) The Mellanox InfiniHost III Ex Dual-Port 4X InfiniBand host channel adapters (HCAs) connect to the host system through a PCI Express x8 interface. Single-data rate (SDR) InfiniHost III Ex cards support dual 10Gb/sec InfiniBand connections. Double-data rate (DDR) versions support dual 20 Gb/sec InfiniBand connections.
Mellanox InfiniHost Dual-Port 10 Gb/sec InfiniBand HCAs with PCI-X (380299-B21) The Mellanox InfiniHost Dual-Port 10 Gb/sec InfiniBand HCAs with PCI-X are dual-port 10 Gb/sec PCI-X HCAs designed for full performance on high-speed InfiniBand fabrics. Their design allows for 10 Gb/sec database or HPC clustering, and provide the high throughput and low CPU utilization required by those applications.
Mellanox InfiniHost III Lx Single-Port InfiniBand HCAs with PCI Express (431038-B21 and 431039-B21) The Mellanox InfiniHost III Lx single-port InfiniBand host channel adapters (HCAs) with PCI Express connect to the host system through a PCI Express interface. The single-data rate (SDR) cards support 10 Gb/sec InfiniBand connections. The double-data rate (DDR) cards support 20 Gb/sec connections.
