120 Implementing Cisco InfiniBand on IBM BladeCenter
򐂰 The 3012 (and thus the Ethernet gateway module) supports four different options for
configuring:
–CLI
– GUI - http
– GUI - Element Manager
–SNMP
򐂰 LED meanings at the gateway module level:
– Green – InfiniBand Module Status Indicator
• On – Module active
• Off – Module inactive
– Yellow – InfiniBand Attention Indicator
• On – Attention required (Something is wrong)
• Off – All OK
򐂰 Port Level LED meanings
– Dual color LED
• Off – no signal
• Solid Yellow – Port Disabled
• Flashing Yellow – Port Fault
• Solid Green – Port online
–Green LED:
• Off – no traffic
• Blinking – traffic exists on port
7.1.1 Some general assumptions
All examples in this chapter make the following assumptions:
򐂰 An SFS3012 is in use for gateway support to Ethernet.
򐂰 The basic operation of the 3012 (for example, out-of-band management) have already
been configured, and you can communicate with the 3012 by either telnet or the Element
Manager (depending on if you want to use a CLI or a GUI).
򐂰 All GUI examples are from the Element Manager. (There is similar functionality available
from the built-in http access to the 3012, but we do not discuss that functionality here.)
򐂰 All necessary cabling is already in place.
򐂰 Examples are provided on how to configure the various gateway options through CLI and
the Element Manager GUI.
򐂰 The Element Manager used for GUI configuration examples in this section was version
2.9.0.10, running on JVM™ 1.4.2_05.
򐂰 The TopSpin operating system used on the 3012 was Topspin-360 TopspinOS 2.8.0
releng #127 03/15/2007 22:37:23.
򐂰 InfiniBand clients used for testing gateway access were IBM BladeCenter HS21 servers
(machine type 8853), running Red Hat Enterprise Linux 5, Kernel 2.6.18-8.el5, and OFED
(OpenFabrics Enterprise Distribution) host InfiniBand driver version OFED-1.2
1.2-2.6.18_8.el5.
򐂰 All clients discussed are using the default p_key (ff:ff) for IP over InfiniBand traffic.
Configuring for non-default p_keys is not necessarily a difficult task, but it is beyond the
scope of this document.
