ILOM: Integrated Lights Out Management
Integrated Lights Out Management (ILOM) is the Service Processor. ILOM enables multiple in-band and out-of-band management
solutions. In-band management through the host operating system, or platform, is enabled by IPMI and SNMP OS-resident agents.
Out-of-band management is enabled through the serial port or dedicated Ethernet. There is a command line interface (CLI) provided
when out-of-band serial port conenctivity is used. The dedicated Ethernet connectivity to out-of-band management features includes:
• Web interface
• CLI via SSH
• IPMI 2.0
• SNMP v1, v2c, and v3
• CLI via SSH
• IPMI 2.0
• SNMP v1, v2c, and v3
ILOM Architecture
The Sun Fire X4100 M2 and X4200 M2 servers leverage the same ILOM design and part. ILOM is a Sun-designed Field Replaceable Unit
(FRU) daughtercard. The ILOM daughtercard has the following features:
• Motorola MPC8248 PowerPC processor
• 32-bit 266 MHz
• 16 Kb 4-way associative data cache
• 16 Kb 4-way associative instruction cache
• 64-bit data bus
• 66 MHz PCI bridge
• 64 MB PC-133 MHz SDRAM
• 16-bit 32 MB Flash ROM
• DVI output
• USB connections to AMD-8111 I/O Hub
• LPC (Low Pin Count) connection to AMD-8111 I/O Hub
• 10/100 Mb Integrated LAN
• 3 serial ports (Debug, RS485, external)
• Half-size standard PCI form factor
• 32-bit 266 MHz
• 16 Kb 4-way associative data cache
• 16 Kb 4-way associative instruction cache
• 64-bit data bus
• 66 MHz PCI bridge
• 64 MB PC-133 MHz SDRAM
• 16-bit 32 MB Flash ROM
• DVI output
• USB connections to AMD-8111 I/O Hub
• LPC (Low Pin Count) connection to AMD-8111 I/O Hub
• 10/100 Mb Integrated LAN
• 3 serial ports (Debug, RS485, external)
• Half-size standard PCI form factor
The ILOM daughtercard is a standalone system with no dependencies on the operating system. It has availability to physical inter-
faces through the connections listed above. The actual devices, however, are located on the main system board. The DVI output port
is connected to the ATI Rage XL via FPGA to enable remote graphics redirection from ILOM with a maximum VGA resolution of 1024 x
768. Three USB connections to the AMD-8111 I/O Hub are used to provide remote keyboard, mouse, and storage functionality. There
is an LPC connection to the AMD-8111 I/O Hub via FPGA. The 10/100 Mb Ethernet is connected to the onboard Broadcom BCM5221
10/100 Ethernet controller which automatically
detects straight or cross-over Ethernet cables. The external serial port is multiplexed with the main system serial port for access to
