Installing And Maintaining The Isr 9024 Interconnect; Overview Of The Isr 9024 Interconnect - HP Cluster Platform Interconnects v2010 User Manual

2 Installing and Maintaining the ISR 9024 Interconnect

The hardware maintenance operations described in this chapter require appropriate training
and knowledge of safety procedures. The safety procedures for Cluster Platform are described
in the HP Cluster Platform Site Preparation Guide. The following interconnect maintenance topics
are described:
• Overview of the ISR 9024
• Unpacking the ISR 9024
• Mounting the ISR 9024 in the rack
• Installing the ISR 9024 power supply unit
• Operating the ISR 9024 interconnect (
This is an older model which is still supported. For information on the ISR 9024 S/D RoHS
compliant model refer to

2.1 Overview of the ISR 9024 Interconnect

The InfiniBand interconnect, ISR 9024 is a scaleable high-bandwidth interconnect employing the
embedded InfiniScale III switch chip. An embedded InfiniBand subnet manager and the
management software enable you to collect performance statistics and environmental monitoring
data. The subnet manager software automatically discovers the fabric topology and configures
the hosts and switches. Internally managed ISR 9024 units are equipped with a management
card that you access through either an Ethernet port (out-of-band management) or to a serial
port (console CLI management). Externally managed ISR 9024 units support in-band management
over the InfiniBand fabric and also provide an I²C port for channel management purposes.
An industry-standard management information base (MIB) is provided, enabling you to administer
the interconnect by using SNMP or InfiniBand in-band management. You configure and manage
the fabric by using either the integrated graphical user interface (GUI), or the command line
interface (CLI). You use a console, remote telnet, or HTTP (Java client) connection to access the
interconnect's management interfaces. The management interfaces enable you to monitor,
upgrade, and troubleshoot the interconnect and its network (fabric). Technical specifications for
the ISR 9024 are provided in
The ISR 9024 is a 24-port 4x or 12x (10 Gb/s) modular InfiniBand interconnect that is capable of
switching all ports simultaneously at full wire speed. The interconnect contains a single 24
InfiniBand 4X port switch chip. This switch chip incorporates an internal crossbar switch capable
of supporting cut-through switching to minimize latency.
This 24-port chassis functions as a standalone unit in small clusters of up to 24 servers, or as a
building block for larger clusters. Larger clusters are constructed from multiple ISR 9024
interconnects functioning as the cluster building blocks. In larger configurations, only a single
internally-managed ISR 9024 is required to run the management software, while the other
interconnects are externally managed. (Using two internally managed devices ensures that the
fabric management has high availability).
The ISR 9024 chassis is a 1U-high 19-inch wide rack mounted ANSI and ETSI-compliant chassis
that contains the following modules:
• The base board, which hosts the InfiniScale III switch chip and provides the following:
— 24 4x 10 Gb/s port switch.
— 12 4x physical connection to base board ports.
— Switch to PCI bridge.
— Base board to management card interface.
