Networking and I/O are provided by the following:
The Intel IbexPeak I/O PCH provides legacy function support similar to that of ICH-family devices, but with extensions in Serial-ATA technology and 64-bit and 66-MHz PCI-X support. The PCH I/O also includes integrated USB 2.0 support, an LPC interface, a system management interface, a power management interface, and PECI interface.
IbexPeak provides platform I/O extensions with the following features:
SATA port for CF access
PCIe 1.0 port x 1 for Management LAN
SPI Interface (BIOS)
LPC Interface (SuperIO and IPMC)
2 USB 2.0 ports
Integrated Trusted Platform Module
The blade server supports a compact flash card for user flash. The card is connected to the SATA interface from IbexPeak PCH using a SATA to IDE controller. The blade server supports 16-GB cards. Once installed, the cards are not externally accessible when the blade server is operating.
There is no support for drives mounted directly to the blade server, and the blade server itself does not contain any native support for SAS or SATA drives.
The PCIe 2.0 ports can negotiate 1.0 and 2.0 speeds. The LC5518 processor has four PCIe 2.0 port interfaces with x16 lanes that are configured as follows:
x8 PCIe 2.0 to 82599 controller
x8 PCIe 2.0 to AMC
x8 PCIe 2.0 to ARTM (zone 3)
x4 PCIe 2.0 to 82576EB controller Base
x4 PCIe 2.0 (One x4 root port is configured to an NTB device interface (for update channel), which is currently not supported.)
Two BIOS flash devices are connected through the SPI interface from the IbexPeak PCH.
The LPC bus is a multiplexed (command, address, and data) serialized 4-bit bus with optional side band signals. It replaces the ISA and X-bus and reduces pin count (approximately 40) over the ISA and X-bus.
The LPC is software transparent and does not require special drivers or configuration for its interface. The motherboard BIOS configures all devices at boot up. The motherboard BIOS has the ability to support a variable number of wait states, to have I/O and memory cycles retried in SMM handler, and to support wake-up and other power-state transitions. The design meets LPC 1.0 design guidelines.
The LPC bus provides system connectivity to the following devices:
TPM
IPMC
RS-232 serial ports
The blade server is the first Oracle ATCA blade server to use the Intel 82599 controller for 10-GbE extended fabric interface. It is connected to CPU0 through an x8 PCIe link.
The controller provides two 10-Gbit XAUI Ethernet connections to the ATCA backplane extended fabric, where four lanes are driven at 3.125 Gbyte per second (if the ATCA switch supports 10-Gbit Ethernet) or a single lane at 1.25 Gbyte per second if the switch is a 1-Gbit Ethernet device.
Note - The 82599 controller is supported only on 10G. Support for 1G on earlier generation blade servers is not available.
Two separate dual 1GbE Intel 82576EB controllers provide control for base and management interfaces.
The base interface controller is connected to the x4 PCIe 2.0 to 82576EB controller Base port from CPU0.
The management interface controller is connected to the x1 PCIe port from the IbexPeak PCH.
The blade server provides two BIOS PROMs attached to the SPI bus for increased reliability.
Each PROM is an 32-Mb flash device. The primary flash device (FWH0) contains the primary BIOS image, factory default settings, and user-configured settings. The primary BIOS chip is automatically selected for update during a firmware upgrade.
The secondary flash device (FWH1) contains a backup copy, normally of the last known good BIOS image, factory default settings, and last good user-configured settings. The secondary BIOS retains the original BIOS image, and can be used through manual configuration if the primary BIOS becomes corrupted.
In the event of checksum error or other failure during boot from primary BIOS image, you can switch the system over to the secondary BIOS image using H8 to allow system boot recovery.
The blade server supports a single IDE compact flash card, 16-GB capacity.
The Renesas H8S/2462 IPMC provides the IPM controller function on the blade server. The IPMC provides PICMG 3.0 board management functionality for monitoring, event logging, and recovery control,. The IPMC also provides management interfaces to the payload through a serial interface.
The IPMC provides the following:
Hot-swap latch input and LED control
Payload power control
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 (819-1178).
CPU temperatures are measured using a maximum 6631 device across the Intel proprietary PECI bus. An offset of 95oC is added to provide a normalized temperature reading.
The Intel processor junction temperature is monitored for each CPU. The internal memory temperature is monitored for each installed DIMM. There could also be one or more sensors on an installed AMC.
Upper Non-Critical 80oC
Upper Critical 86oC
Upper Non-Recoverable 94oC
For detailed mapping of the sensors, refer to the Sun Netra CT900 Server Software Developer’s Guide (819-1178).
An RS-232 serial port is available on the front panel using an RJ-45 connector. This same port is also wired through the Zone 3 connectors to provide a copy of this port on the ARTM. This connector shares the SuperIO chip Port A with the H8-IPMI controller, to allow console messages to be directed to the H8 when the external ports are not in use.
The blade server detects a valid RS-232 connection to either the front or rear port and automatically disconnects the SuperIO port from the H8 and connects to the external ports.
The blade server supports AMC drives that contain their own PCIe-based controller chip connecting to the system through the PCIe bus. The blade server supports an AMC that contains drives using Port 2 or 3 SAS connections, only when a Netra CP32x0 ARTM is present.
If present, the Sun Netra CP32x0 drives the AMC Port-2 signals. This support speeds up to 3 Gb per second.
There is no support for drives mounted directly to the blade server, and the blade server itself does not contain any native support for SAS or SATA drives.
The blade server uses the Infineon SLB9635 a 
TPM chip, which enables various
security features, including hardware and software authentication for the x86 platform. This chip is
reserved for future use.
