System Management Technology
As the number of systems grow in any organization, the complexities of managing the
infrastructure throughout its lifecycle becomes increasingly difficult. Effective system
management requires both integrated hardware that can sense and modify the
behavior of key system elements, as well as advanced tools that can automate key
administrative tasks.
Integrated Lights-Out Management (ILOM) System Controller
Provided across many of Sun’s x64 servers, the Integrated Lights Out Management
(ILOM) service processor acts as a system controller, facilitating remote management
and administration of Sun SPARC Enterprise T5120 and T5220 servers.The service
processor is fully featured and is similar in implementation to that used in other Sun
modular and rackmount x64 servers. As a result, Sun SPARC Enterprise T5120 and T5220
servers integrate easily with existing management infrastructure.
Critical to effective system management, the ILOM service processor:
• Implements an IPMI 2.0 compliant services processor, providing IPMI management
functions to the server's firmware, OS and applications, and to IPMI-based
management tools accessing the service processor via the ILOM Ethernet
management interface, providing visibility to the environmental sensors (both on the
server module, and elsewhere in the chassis)
• Manages inventory and environmental controls for the server, including CPUs,
DIMMs, and power supplies, and provides HTTPS/CLI/SNMP access to this data
• Supplies remote textual console interfaces,
• Provides a means to download upgrades to all system firmware
The ILOM service processor also allows the administrator to remotely manage the
server, independent of the operating system running on the platform and without
interfering with any system activity. ILOM can also send e-mail alerts of hardware
failures and warnings, as well as other events related to each server. The ILOM circuitry
runs independently from the server, using the server’s standby power. As a result, ILOM
firmware and software continue to function when the server operating system goes
offline, or when the server is powered off. ILOM monitors the following Sun SPARC
Enterprise 5120 and 5220 server conditions:
• CPU temperature conditions
• Hard drive presence
• Enclosure thermal conditions
• Fan speed and status
• Power supply status
• Voltage conditions
• Solaris watchdog, boot time-outs, and automatic server restart events
