Server Management
There are several options for remotely managing a Sun Fire V20z or Sun Fire V40z
server:
■ Lights Out Management (LOM) through IPMItool
■ Simple Network Management Protocol (SNMP)
Service Processor
The Sun Fire V20z and Sun Fire V40z servers include a dedicated chipset for
complete operating-system independence and maximum availability of
server-management functions. This chipset, called Service Processor (SP), is an
embedded PowerPC chip providing the following:
■ Environmental monitoring of the platform (such as temperatures, voltages, fan
speeds, and panel switches)
■ Alert messages when problems occur
■ Remote control of server operations (boot, shutdown, and reboot of the server’s
operating system, turning the server’s power on and off, stopping the server’s
boot process in BIOS, and upgrading the BIOS)
Note – In this document, you might see references to a Baseboard Management
Controller (BMC). A BMC is a dedicated IPMI controller. The SP found in these
servers is a general-purpose, embedded CPU that contains software to emulate a
BMC.
Server-Management Interfaces
These servers include local and remote server-management capabilities through the
SP; the SP supports four server-management interfaces:
■ IPMI using a Keyboard Controller Style (KCS) interface and an IPMI kernel driver
(in-band)
■ IPMI over local area network (LAN) (out-of-band)
■ SNMP integration with third-party SNMP management consoles
■ Command-line-interface (CLI) LOM
