Chapter 1. Introduction

This chapter provides a brief introduction to InfiniBand technology and describes

Voltaire ISR 9024, ISR 9096 and ISR 9288 switches.

Introduction About InfiniBand

1-2

1.1 About InfiniBand

InfiniBand technology is a high-performance channel-based interconnect

architecture that provides increased scalability and reliability for servers and other

Internet infrastructure equipment. InfiniBand architecture defines the entire stack,

from the physical to the application layers APIs and fabric management.

InfiniBand has unique capabilities for direct data placement implemented by

RDMA and for OS bypassing, discovery, fail-over, remote boot, I/O sharing, and

other advanced features.

InfiniBand is the IT industry's solution for expanding data network centers to

prepare for the next generation of communications. e-business, Internet use and the

demands of the communications age have created the need for increased processing

power, larger stores of information and a greater, more reliable flow of data. As the

present architecture struggled under the current load of information, it was painfully

clear that a solution was needed in order to manage the increasing demands of the

future. The giants of the IT industry (Compaq, Dell, IBM, Intel, HP, SUN and

Microsoft followed

by more than 230 companies) combined the best elements of

two competing technological initiatives to create InfiniBand, an industry standard

that has been adopted with confidence. Solving a great number of obstacles that

data centers were facing (scalability, reliability, manageability), InfiniBand enabled

the introduction of data clusters, an invaluable next step to data center construction.

In effect, InfiniBand is a fabric-based, switched network that allows devices such as

servers, storage and I/O to communicate at very high speeds. Until the advent of

InfiniBand, communication devices had to wait in line to send their information

through one shared bus. The ten-year-old architecture had reached its limits and did

not have enough bandwidth available to meet the rising demands of the information

load.

InfiniBand architecture is based upon a very different concept. Offering high-speed

interprocessor communication and memory sharing, it enables you to build server

clusters with performance comparable to that of large servers at a fraction of the

price. Instead of one bus through which every device communicates, InfiniBand

architecture offers a network fabric that incorporates numerous switches and router

modules, allowing devices to communicate simultaneously. Speed is no longer

restricted by the shortcomings of the infrastructure. InfiniBand operates at

2.5Gbps (1X), 10Gbps (4X), 20Gbps (4X DDR), 30Gbps (12X) to 60 Gbps (12X

DDR).

InfiniBand architecture is modular, highly scalable (it allows for virtually unlimited

network expansion) and reduces the workload of the operating system kernel and

the CPU, freeing their power to run applications. Offering advanced fault isolation

controls, nonexistent in previous protocols, InfiniBand provides a high level of fault

tolerance. And most importantly, because the InfiniBand system is modular,

processing power based on commodity servers can be added as needed.

Introduction ISR 9024 System Overview

1-3

InfiniBand System Elements

The following are the InfiniBand system elements:

 HCA (Host Channel Adapter), an adapter or silicon chip residing on the host

motherboard providing the host side functionality and advanced reliable

message passing capabilities.



Switch, connecting all the nodes in a switched point-to-point manner.



Router Modules, providing connectivity to other InfiniBand or IP subnets.



Storage (native and Fibre Channel access)

InfiniBand provides a reliable, low latency interconnect (with typical switch latency

of 100nS) with fault-tolerance mechanisms (Automatic Path Migration), physical

multiplexing (Virtual Lanes), physical link aggregation (1X, 4X, 12X) and

security/partitioning.

The InfiniBand fabric provides central management and configuration controlling

discovery, failures and resource allocation.

1.2 ISR 9024 System Overview

The Voltaire ISR 9024 Grid Switch is a high performance, low latency, fully non-

blocking switch for high performance computing (HPC) clusters and grids. Offering

available bandwidth of 480 Gbps, the Voltaire ISR 9024 is an alternative to

proprietary interconnect technologies. With twenty-four 10 Gbpsports in a 1U

chassis, the standards-based ISR 9024 delivers three times the port density of

proprietary offerings. Using the Voltaire ISR 9024 Grid Switch, you can build high

performance clusters and grids that scale from several to hundreds of nodes.

The ISR 9024 serves as a building block for Fat Tree topologies of hundred of

nodes for scientific, commercial HPC and enterprise grid applications. When

combined with the Voltaire ISR 9288/9096 high port density switch, the Voltaire

ISR 9024 enables the formation of clusters scaling to thousand of nodes.

The ISR 9024 architecture features a passive cooling device (with no fans) resulting

in a noise free, high MTBF unit.

1.3 ISR 9288/9096 System Overview

The Voltaire ISR 9288/9096 Grid Backbone is a modular platform for building high

levels of performance and scalability for large high performance computing (HPC)

clusters. The Voltaire ISR 9288/9096 enables high performance applications to run

on distributed server, storage and network resources.

Elegantly designed with 10/30 Gbps of full bisectional bandwidth for up to 96 or

288 4X/12X ports in a single chassis, multiple ISR 9288/9096 can also be

interconnected to form very large clusters.

Possible configurations range from dozens to thousands of nodes with many

upgrade paths available.

Featuring fat tree (Clos) topology that provides full bisectional bandwidth for each

port, the Voltaire ISR 9288/9096 lead the InfiniBand industry with the highest

switching capacity.

Providing unmatched levels of IniniBand bandwidth, the ISR 9096 and the

ISR 9288 respectively support up to 96 and 288 InfiniBand ports, which can be

used in any combination of 10 Gbps 4X Ports and or 30 Gbps InfiniBand 12X

ports. The 12X port incorporates three 4X InfiniBand ports aggregated into a single

InfiniBand port.
