Intel H2000WP Technical Product Specification - Page 42

Product Architecture Overview Intel® Server Board S2600WP TPS security information. The RTC also supports a date alarm that allows for scheduling a wake up event up to 30 days in advance, rather than just 24 hours in advance. 3.4.12 GPIO Various general purpose inputs and outputs are provided for custom system design. The number of inputs and outputs varies depending on the Intel® C600-A PCH configuration. 3.4.13 Enhanced Power Management The Intel® C600-A PCH power management functions include enhanced clock control and various low-power (suspend) states. A hardware-based thermal management circuit permits software-independent entrance to low-power states. The PCH contains full support for the Advanced Configuration and Power Interface (ACPI) Specification, Revision 4.0a. 3.4.14 Fan Speed Control The Intel® C600-A PCH integrates four fan speed sensors (four TACH signals) and four fan speed controllers (three Pulse Width Modulator signals), which enables monitoring and controlling up to four fans on the system. With the new implementation of the single-wire Simple Serial Transport (SST) 1.0 bus and Platform Environmental Control Interface (PECI), the PCH provides an easy way to connect to SST-based thermal sensors and access the processor thermal data. 3.4.15 Intel® Virtualization Technology for Direct I/O (Intel® VT-d) The Intel® Virtualization Technology is designed to support multiple software environments sharing same hardware resources. Each software environment may consist of an OS and applications. The Intel® Virtualization Technology can be enabled or disabled in the BIOS setup. The default behavior is disabled. Note: If the setup options are changed to enable or disable the Virtualization Technology setting in the processor, the user must perform an AC power cycle for the changes to take effect. The chipset supports DMA remapping from inbound PCI Express* memory Guest Physical Address (GPA) to Host Physical Address (HPA). PCI devices are directly assigned to a virtual machine leading to a robust and efficient virtualization. 3.4.16 KVM/Serial Over LAN (SOL) Function These functions support redirection of keyboard, mouse, and text screen to a terminal window on a remote console. The keyboard, mouse, and text redirection enables the control of the client machine through the network without the need to be physically near that machine. Text, mouse, and keyboard redirection allows the remote machine to control and configure the client by entering BIOS setup. The KVM/SOL function emulates a standard PCI serial port and redirects the data from the serial port to the management console using LAN. KVM has additional requirements of internal graphics and SOL may be used when KVM is not supported. 3.4.17 IDE-R Function The IDE-R function is an IDE Redirection interface that provides client connection to management console ATA/ATAPI devices. When booting from IDE-R, the IDE-R interface will send the client's ATA/ATAPI command to the management console. The management console will then provide a response command back to the client. A remote machine can setup a diagnostic SW or OS installation image and direct the client to boot from IDE-R. The IDE-R 30 Revision 1.2 Intel order number G44057-003
