IBM NeXtScale System Planning and Implementation Guide
7.1 Managing compute nodes
The NeXtScale System compute nodes include local and remote management
capabilities.
Local management capabilities are provided through the keyboard, video, mouse
(KVM) connector on the front of the server (for more information, see 4.14, “Local
server management” on page 103). By using the console breakout cable that is
included with the chassis, you can directly connect to the server console.
Remote management capabilities are provided through the Integrated
Management Module II (IMM2). IMM provides advanced service-control,
monitoring, and alerting functions.
By default, the nx360 M4 compute node includes IMM2 Basic; however, if more
functionality is required, the IMM2 can be upgraded to IMM2 Standard or to
IMM2 Advanced with Features on Demand (FoD) licenses. For more information
about the functionality that is available at each level, see 4.15, “Remote server
management” on page 105.
7.1.1 Integrated Management Module II
In 2009, IBM introduced the IPMI-compliant service processor that is called the
Integrated Management Module (IMM). The IMM and the second-generation
IMM2 are common across all IBM x86 machines, including the IBM NeXtScale
nx360 M4 compute node.
The nx360 M4 compute nodes, and many optional third-party components, are
compliant with Intelligent Platform Management Interface Version 2.0 (IPMI 2.0).
IPMI operates independently of the operating system (OS) with which
administrators can manage a system remotely, even in the absence of the OS or
the system management software or if the monitored system is not powered on.
IPMI also functions when the OS started, and offers enhanced features when it is
used with system management software. The nodes respond to IPMI messaging
to report operational status, retrieve hardware logs, or issue requests. The nodes
can alert by way of the simple network management protocol (SNMP) or platform
event traps (PET).
