Infiband

  1. 1. INFIBANDSK. Khaja Mohiddin
  2. 2. What it is InfiniBand is a switched fabric communications link used in high-performance computing and enterprise data centers. Its features include high throughput, low latency,quality of service and failover, and it is designed to bescalable. The InfiniBand architecture specification defines a connection between processor nodes and high performance I/O nodes such as storage devices.
  3. 3. HistoryInfiniBand originated from the 1999 merger of two competingdesigns:  Future I/O, developed by Compaq, IBM, and Hewlett- Packard  Next Generation I/O (ngio), developed by Intel, Microsoft, and SunInfiniband Trade Association maintains the specificationof both.
  4. 4. Basic Features• High speed, low latency data transport• Bidirectional serial bus• Switched fabric topology • Several devices communicate at once• Data transferred in packets that together form messages • Messages are direct memory access, channel send/receive, or mulitcast• Host Channnel Adapters (HCAs) are deployed on PCI cards
  5. 5. Overview Layered Protocol - Physical - Link, Network - Transport - Upper Layers Packet Based Communication Quality of Service Three Link Speeds - 1X - 2.5 Gb/s, 4 wire - 4X - 10 Gb/s, 16 wire - 2X - 30 Gb/s, 48 wire
  6. 6.  PCB, Copper and Fiber Cable Interconnect Remote DMA Support Multicast and Unicast Support Reliable Transport Methods - Message Queuing Communication Flow Control - Link Level and End to End
  7. 7. InfiniBand Elements
  8. 8. Role of InfiBand InfiBand is ideally suited as the interconnect technology for  Access Layer and Storage components  Application and Back End IPC applications,  for connectivity between Application and Back End layers,  and from Back End to Storage Layers.
  9. 9. Bandwidth Advantages
