12.2. InfiniBand and Storage Networking
Because InfiniBand is a complete revision of conventional I/O, InfiniBand servers cannot directly access the installed base of storage devices. Storage arrays with SCSI, Fibre Channel, or Gigabit Ethernet require an intermediate gateway, both to translate between different physical media and transport protocols and to convert SCSI, FCP, and iSCSI data into InfiniBand format.
One solution is to provide a CA that can accommodate PCI and PCIX adapter cards, including HBAs and Gigabit Ethernet NICs. Such accommodation is almost a certainty, because it would be unreasonable to expect customers to “forklift” their current peripheral, storage, and networking investment to benefit from InfiniBand server clustering ...
