Fabric: InfiniBand* and OPA<br />
InfiniBand/OPA is a multi-lane, high-speed serial interconnect (Copper or Fiber)<br />
• Typically presented as a 4x solution<br />
• Speeds: 40Gb/s (M & Intel QDR), 56Gb/s (M FDR), 100Gb/s (EDR & Intel OPA)<br />
High bandwidth, low latency HPC interconnect for commodity servers<br />
• Ethernet switch latency is typically measured in μs, but InfiniBand/OPA is in<br />
nanoseconds<br />
• Lower CPU load<br />
• Lower cost than Ethernet<br />
– 100GbE measured in multiple $1,000’s per switch port<br />
– 100Gb OPA is ~$1k per switch port (target for <strong>Intel®</strong> OPA list pricing)<br />
