4 Installing and Maintaining the ISR 9096 and ISR 9288
Interconnects
This chapter describes the installation and maintenance of the Voltaire ISR 9096 and the ISR 9288
interconnects. The actual product name will be used when referring to a specific feature or
procedure. When features are common to both interconnects, they are referred to as ISR 9XXX.
The hardware maintenance operations described in this chapter require appropriate training
and knowledge of safety procedures. The safety procedures for HP Cluster Platform are described
in the HP Cluster Platform Overview and the HP Cluster Platform Site Preparation Guide. The
following interconnect maintenance topics are described in this chapter:
•
An overview of the ISR 9XXX interconnects ( Section 4.1 )
• Unpacking the chassis ( Section 4.2 ).
• Repacking the chassis ( Section 4.3 ).
• Mounting the interconnect in the rack ( Section 4.4 ).
• Standard interconnect configurations ( Section 4.5 ).
• Post-installation tasks ( Section 4.6 ).
These are older models which are still supported. For the latest documentation of new
interconnects go to

4.1 Overview of the ISR 9XXX Interconnects
The ISR 9XXX interconnect is a modular platform for building high levels of performance and
scalability for large high performance computing (HPC) clusters. The ISR 9XXX enables high
performance applications to run on distributed server, storage and network resources. You can
interconnect multiple ISR 9XXXs to create large clusters.
The ISR 9XXX provides a fat tree (Clos) topology that provides full non-blocking bisectional
bandwidth for each port. The ISR 9288 supports up to 288 InfiniBand 4X (10 Gb/s) ports. The ISR
9096 supports up to 96 InfiniBand 4X (10 Gb/s) ports. Both have a latency of less than 420
nanoseconds.
In addition to scalable InfiniBand switching, the ISR 9XXX offers powerful multi-protocol
connectivity in a single chassis. In specific configurations, the chassis hosts the router blades,
providing seamless connectivity between server clusters, FC SANs, NAS appliances, IP SANs
and TCP/IP networks (LANs). InfiniBand-to-TCP/IP and InfiniBand-to Fibre Channel router
blades can be mixed and matched in any combination and up to 32 ports router ports are
supported in a single chassis.
The following topics are described in this section:
•
ISR 9XXX interconnect features ( Section 4.1.1 ).
• ISR 9XXX interconnect architecture ( Section 4.1.2 ).
• ISR 9XXX building blocks ( Section 4.1.3 ).
• ISR 9XXX firmware ( Section 4.1.4 ).
• ISR 9XXX control panels and reset buttons ( Section 4.1.5 ).
Important:
Do not mix SDR and DDR components in a chassis.
