3 Installing the Interrack and Intersystem Cables
After the HP SFS system hardware has been set in place and the racks bolted together, the HP
SFS hardware components in the various racks must be cabled to associated hardware in other
racks. Also, the HP SFS hardware must be cabled to the interconnect of a supported compute
cluster, and some HP SFS hardware may be cabled to the site network.
This chapter discusses how to cable the racks in an HP SFS configuration and how to connect an
HP SFS configuration to a compute cluster or standalone server.
Appendix A “Wiring Tables” provides wiring tables for the management network.
3.1 Connecting the HP SFS Interrack Cables
This section discusses the cables that must be connected between the various racks of an HP SFS
system.
3.1.1 Cabling the Management Network ProCurve Switch
The iLO and NIC1 ports of the administration server, MDS server, and each Object Storage Server
are connected to a management network ProCurve Switch.
Note:
The iLO and NIC1 connections for the MDS and administration servers, and any Object Storage
Servers in the base rack are already made to ProCurve Switch #1.
You must connect cables from the iLO and NIC1 ports on the Object Storage Servers in the
expansion cabinets to the ProCurve Switches in the base cabinet.
The connections depend on the type of server, the number of Object Storage Servers, and the
ratio of HP SFS20 Enclosures to Object Storage Servers.
See Table A-16 “Ethernet Switch 1 for 1:1 Configurations with between 2 and 10 Object Storage
Servers” through Table A-31 “Ethernet Switches 3 for 3:1 or 4:1 Configurations with between 24
and 34 Object Storage Servers” to determine the connections for your configuration.
3.2 Intersystem Cables
This section discusses the cables that must be connected between an HP SFS system and the
following:
• A supported compute cluster
• The site network
When connecting SFS to HP Cluster Platform, use the following generic cabling algorithm for
all interconnects:
1. Cabling always starts from the last physical port (highest port number).
2. Ensure that all cabling is complete for the cluster platform control node, which always uses
the last available interconnect port (highest port number).
3. Ensure that all cabling is complete for the cluster platform utility nodes, which begins after
the control node, working downward (second highest port number downward).
4. Ensure that cabling is complete for all cluster platform application nodes, starting from the
first physical port (lowest port number upward).
5. Any remaining ports are available for SFS node links, subject to any cabling rules specified
in the SFS software documentation.
