9.2 Integrated Management Module (IMM)
The Integrated Management Module (IMM) offers these overall features and functions:
򐂰
Provides diagnostics, virtual presence, and remote control to manage, monitor,
troubleshoot, and repair from anywhere
򐂰 Securely manages servers remotely, independently of the operating system state
򐂰
Helps remotely configure and deploy a server from bare metal
򐂰 Auto-discovers the scalable components, ports, and topology
򐂰
Provides one IMM firmware for a new generation of servers
򐂰 Helps system administrators easily manage large groups of diverse systems
򐂰
Requires no special IBM drivers
򐂰 Works with IBM Systems Director to provide secure alerts and status, helping to reduce
unplanned outages
򐂰
Uses standards-based alerting, which enables upward integration into a wide variety of
enterprise management systems
In general, there are two methods to manage an IMM:
򐂰 Out-of-band management: All management tasks are passed directly to the system’s IMM
via a network connection. No drivers are required for the IMM, because it is configured
with its own IP address and is connected directly to the network.
򐂰
In-band management: All management tasks are passed to the system using the
operating system installed on it. The tasks can apply to the operating system, or they can
apply to the IMM that is installed on the system. If the tasks are to be passed to the IMM,
the relevant operating system driver must be installed for the IMM.
In the following section, we look at both the out-of-band and in-band initial configuration.
9.2.1 IMM out-of-band configuration
The x3690 X5 and the x3850 X5 vary slightly from the HX5 in the way that their IMMs are
managed out-of-band. You can configure the IMM to send hardware alerts, for example,
directly to a management system. Although the HX5 has its own IMM, there is no direct
external network access to it and the Advanced Management Module (AMM) in the
BladeCenter chassis must be used to manage the blade.
Configuring an x3850 X5 or x3690 X5 for out-of-band management
The IMM for both the x3690 X5 and the x3850 X5 can be managed over one of two ports:
򐂰 The dedicated system management port on the rear of each chassis.
This port allows the IMM to be connected to an isolated management network for
improved security.
򐂰
The onboard Ethernet port 1 on the rear of each chassis. The IMM shares this port with
the operating system.
This option is provided to allow the IMM to be managed out-of-band without using
additional ports on an external network switch.
