InfiniBand introduction

What is InfiniBand
->A superset of the Virtual Interface Architecture
->Powerful new architecture designed to support I/O connectivity for the Internet infrastructure
->A switched fabric communications link primarily used in HPC and EDC, a high-bandwidth,  low-latency interconnect architecture.
->Defines a connection between processor nodes and high performance I/O nodes (storage devices)
->Point-to-point bidirectional serial link, like PCI-E
->It supports several signalling rates, 2.5/5/10Gb/s
->Links can be bonded together for additional bandwidth
->Each processor contains a host channel adapter (HCA) and each peripheral has a target channel adapter (TCA).
->Support "in the box" and "out of the box" Architecture
->Capable of IPC, storage I/O, network I/O
->Capable of supporting tens of thousands of nodes in a single subnet
