1 1 Introducing the InfiniBand System This chapter gives an overview of the following: • “About the HP 24-Port 4x Fabric Copp er Switch User Guide” on page 1 • “Maximize Server Networks” on page 1 • “What is InfiniBand?” on page 2 • “How Does InfiniBand W ork?” on page 2 About the HP 24-Port 4x Fa bric Copper Switch User Gui[...]

2 What is InfiniBand? InfiniBand (IB) is a high speed, h igh density seri al interconnect that incr eases CPU utilization, decreases latency , and eases the management pain of data centers . The term “InfiniBand” refers to the entire hard ware, communication , and management infrastructure. Use of this technology increases the communicati on sp[...]

3 devices. This protocol allows InfiniBan d hosts to natively send SCSI commands as if the storage was direct attached. The SRP protocol is designed to operate using an RDMA com munication service. An RDMA communication service provides communication between pairs of consumers; it uses messages for control information and RDMA operat ions for data [...]

4 The Queue Pair (QP) is one of the primary architectural elements of InfiniBand. In InfiniBand, communication occurs between Queue Pairs, instead of between ports. A Queue Pair (QP) in an addressable entity , and consists of two W ork Queues: 1). Send W ork Queue and a 2). Receive W o rk Queue. (A work queue prov ides a verb consumer with the abil[...]

5 • Local Identifiers (LIDs) • Global Unique Identifier (GUIDs) • Partition Key (P_Keys) • Configur es switch forwardi ng tables. • Receives traps from Subnet Management Agents (SMAs ). • Sweeps the subnet, discovering topolo gy change s and managing changes as nodes are added and deleted. Understanding the Subnet Management Agent s (SM[...]

6 • Routing internally within a sw itch (hops between switch chips) • Routing between whole switch es (hops between nodes). This is also referred to as routing between “switch elements.” Internal switch routing can be configu red to provide the highest perform ance in passing traffic, and to minimize the threat of congestion within the swit[...]

7 Determine the First Path that will be Discovered The SM Routing Algorithm selects th e first best path that it finds. If multiple paths with the same properties are available then the first of these paths found is the one that is selected. Therefore, it is possible to setup the cabling between switch elements to force the algo rithm to prio ritiz[...]
