IBM BladeCenter PS700 User Manual

64 IBM BladeCenter PS700, PS701, and PS702 Technical Overview and Introduction
SOL offers the following advantages:
򐂰 Remote administration without keyboard, video, or mouse (headless servers)
򐂰 Reduced cabling and without requiring a serial concentrator
򐂰 Standard Telnet interface, eliminating the requirement for special client software
The IBM BladeCenter AMM CLI provides access to the text-console command prompt on
each blade server through a SOL connection, enabling the blade servers to be managed from
a remote location.
In the BladeCenter environment, the SOL console data stream from a blade is routed from
the blades’s service processor to the AMM through the on-blade switch to the network
infrastructure of the BladeCenter unit, including an Ethernet-compatible I/O module that
supports SOL communication. Figure 2-19 shows the SOL data stream flow.

BladeCenter components are configured for SOL operation through the BladeCenter AMM.
The AMM also acts as a proxy in the network infrastructure to couple a client running a Telnet
or SSH session with the management module to an SOL session running on a blade server,
enabling the Telnet or SSH client to interact with the serial port of the blade server over the
network.
Because all SOL traffic is controlled by and routed through the AMM, administrators can
segregate the management traffic for the BladeCenter unit from the data traffic of the blade
servers. To start an SOL connection with a blade server, perform the following steps:
1. Start a Telnet or SSH CLI session with the AMM.
2. Start a remote-console SOL session with any blade server in the BladeCenter unit that is
set up and enabled for SOL operation.
