Networking and I/O

Networking and I/O are provided by the following:

• PCI Express Interface

• Base and Fabric Interfaces

• Serial Interface and Port

• Compact Flash Support

• IPMC

• Hardware Monitoring

• Temperature Monitoring

• USB Ports

PCI Express Interface

All I/O is provided through the SPARC T3 PCI-express interface.

Dual x8 PCIe 2.0 ports can negotiate 1.0 and 2.0 speeds. The blade server uses the PCIe switch in a configuration of eight PCIe 2.0 port interfaces that are configured as follows:

• x8 PCIe 2.0 upstream port-to-processor

• x4 PCIe 2.0 to Ethernet management (front or rear Zone 3)

• x4 PCIe 2.0 to Base interface

• x1 PCIe 2.0 for PCIe to PCI bridge

• x8 PCIe 2.0 for ARTM (Zone 3)

Base and Fabric Interfaces

The Base interface extends from the Intel 82576 NIC connected to the PCIe switch through a x4 connection. The PCIe switch then connects to the SP and to the Base interface.

Dual (redundant) 10/100/1000BaseT Ethernet links are connected to the midplane base interface channels.

The x4 PCIe 2.0 lane port is connected from the PCIe switch to a 1GbE Intel 82576EB controller to provide control for Base interface.Also, the Base connects to the H8 micro-controller through the sideband interfaces for NetConsole requirements.

Two 10-G Ethernet XAUI ports provide the Fabric interface. The XAUI ports are multiplexed between the Zone 2 connector on the midplane and the Zone 3 connector on the midplane (ARTM). Switching between the midplane and ARTM is controlled by the IPMC through the FPGA.

For more information on controllers, refer to Intel’s web site www.Intel.com.

Serial Interface and Port

An RS-232 serial port is available on the front panel using an RJ-45 connector. This same port is wired through the Zone 3 connectors to provide a copy of this port to the ARTM.

The blade server detects a valid RS-232 connection to either the front or rear port and automatically disconnects the serial port used for NetConsole from the IPMC to the external ports.

Trusted Platform Module

The blade server uses the Infineon SLB9635, a TPM chip, which enables various security features, including hardware and software authentication. This chip is reserved for future use.

Compact Flash Support

The blade server supports a single 32-GB capacity compact flash card.

Hardware Monitoring

The blade server uses an ADM1026 hardware monitor device for monitoring on-board voltages. Other functions of the ADM1026 are not used by the blade server.

The monitored voltages are as follows:

• Primary blade voltages (12V, 5V, and 3.3V)

• Standby voltages (3.3V)

• Five core and chipset voltages

• Four DDR3 voltages

• Battery voltages

Sensors are created for each voltage that is monitored.

For detailed mapping of the sensors, refer to the Sun Netra CT900 Server Software Developer’s Guide.

Temperature Monitoring

CPU temperatures are measured using a maximum 6631 device across the ADM1026.

The Intel processor junction temperature is monitored for each CPU. The internal memory temperature is monitored for each installed DIMM.

• Upper Non-Critical 85^oC (185 ^oF)

• Upper Critical 95^oC (203 ^oF)

• Upper Non-Recoverable 110^oC (230 ^oF)

For detailed mapping of the sensors, refer to the Sun Netra CT900 Server Software Developer’s Guide.

USB Ports

Two USB 2.0 ports are routed from the NEC USB to the front panel.
