Sun SPARC Enterprise T5120 and T5220 Server Architecture

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
