[san-tech][03194] Mellanox: FDR 56Gb/s InfiniBandスイッチ発表, June 20, 2011

"Mellanox Introduces ConnectX-3, The Industry's First FDR 56Gb/s
 InfiniBand and 10/40 Gigabit Ethernet Multi-Protocol Adapter;
 Delivers World-Record Bandwidth and Latency Performance"
 June 6, 2011

  "... today announced the availability of its performance-leading
   ConnectX-3 Virtual Protocol InterconnectR (VPI) adapter ICs and
   cards, providing next-generation FDR 56Gb/s InfiniBand and 10/40GbE
   connectivity combined with the next-generation PCI Express 3.0 host
   bus for unprecedented scalability and fabric flexibility."

"Mellanox forges switch-hitting ConnectX-3 adapters"
 6th June 2011
  "When running the InfiniBand protocol, it supports Remote Direct
   Memory Access (RDMA); Fibre Channel over InfiniBand (FCoIB); and
   Ethernet over InfiniBand (EoIB)."
  "On the Ethernet side, the ConnectX-3 chip implements 10GE or 40GE
   protocols and supports RDMA over Converged Ethernet (RoCE), Fibre
   Channel over Ethernet (FCoE), and Data Center Bridging (DCB). The
   new silicon also supports SR-IOV - an I/O virtualization and
   isolation standard for Ethernet networks that allows multiple
   operation systems to share a single PCI device - and IEEE 1588,
   a standard for synchronizing host server clocks to a master data
   center clock."
  "Mellanox is only beginning its benchmark tests on the ConnectX-3
   chips, but Monson says the performance and thermal characteristics
   of the chips are encouraging. The current ConnectX-2 chips support
   Ethernet with RoCE extensions have a latency of around
   1.3 microseconds per 10GE port compared to something on the order
   of 5 to 10 microseconds for other commercially available adapters.
   With the ConnectX-3 chip implemented in an FDR InfiniBand or 40GE
   port with either RDMA or RoCE turned on will get sub-microsecond
   latency. And, says Monson, that ConnectX-3 port will consume under
   3 watts, which compares favorably to the 8 to 10 watts per port
   other network interface cards offer today."
John Monson, vice president of marketing at Mellanox

IEEE 1588
  "Precise time information is especially important for distributed
   systems in automation technology. With the Precision Time Protocol
   (PTP) described in IEEE 1588, it is possible to synchronise
   distributed clocks with an accuracy of less than 1 microsecond via
   Ethernet networks for the very first time. The demands on the local
   clocks and the network and computing capacity are relatively low."
