Chapter 4: AMI BIOS

Execute-Disable Bit Capability (Available when supported by the OS and the CPU)

Set to Enabled to enable the Execute Disable Bit which will allow the processor to designate areas in the system memory where an application code can execute and where it cannot, thus preventing a worm or a virus from flooding illegal codes to overwhelm the processor or damage the system during an attack. The default is Enabled. (Refer to Intel and Microsoft Web Sites for more information.)

Simultaneous Multi-Threading (Available when supported by the CPU)

Set to Enabled to use the Hyper-Threading Technology, which will result in increased CPU performance. The options are Disabled and Enabled.

Active Processor Cores

Set to Enabled to use a processor's Second Core and beyond. (Please refer to Intel's web site for more information.) The options are All, 1 and 2.

Intel® EIST Technology

EIST (Enhanced Intel SpeedStep Technology) allows the system to automatically adjust processor voltage and core frequency in an effort to reduce power consump- tion and heat dissipation. Please refer to Intel’s web site for detailed informa- tion. The options are Disable and Enable.

Intel® Turbo Boost Technology (Available if Intel® EIST technology is Enabled)

This feature allows processor cores to run faster than marked frequency in specific conditions. The options are Disabled and Enabled.

C1E Support

Select Enabled to use the "Enhanced Halt State" feature. C1E significantly reduces the CPU's power consumption by reducing the CPU's clock cycle and voltage during a "Halt State." The options are Disabled and Enabled.

Intel® C-STATE Tech

If enabled, C-State is set by the system automatically to either C2, C3 or C4 state. The op- tions are Disabled and Enabled.

Intel® C-STATE Architecture

C-State, a processor power management architecture developed by Intel, can further reduce power consumption from the basic C1 (Halt State) state, which blocks clock cycles to the CPU. C-State is an idle state, and instructions are not processed by the CPU. A brief explanation of all the C-States are as follows:

C0 - Active. The CPU is processing instructions.

X8SIL-V, X8SIL-F, X8SIL specifications

SUPER MICRO Computer X8SIL, X8SIL-F, and X8SIL-V are advanced server motherboards designed to meet the demanding needs of today's data centers and enterprise environments. These motherboards from Supermicro deliver exceptional performance, scalability, and reliability, making them suitable for a wide range of applications, including virtualization, cloud computing, and database management.

One of the main features of the X8SIL series is its compatibility with Intel's Xeon 5500 and 5600 series processors. This allows users to harness the power of multi-core technology, ensuring optimal performance for both single-threaded and multi-threaded applications. With support for up to 144GB of DDR3 ECC memory, the X8SIL motherboards provide ample memory bandwidth, enhancing the overall system performance and efficiency.

The X8SIL-F variant includes an integrated IPMI (Intelligent Platform Management Interface) feature, which enables remote management and monitoring of the system. This technology allows IT administrators to proactively manage server health, perform remote troubleshooting, and ensure minimal downtime. Additionally, the X8SIL-F supports Supermicro's Green Computing technology, which helps reduce power consumption and enhance energy efficiency, leading to lower operational costs.

In terms of storage, the X8SIL series offers multiple SATA and SAS interface options, facilitating a wide range of storage configurations. The motherboards feature six SATA II ports and optional SAS capabilities, allowing users to implement RAID setups for improved performance and data redundancy. This flexibility in storage solutions is crucial for environments that require high availability and reliability.

The X8SIL motherboard series is equipped with a range of I/O ports, including multiple USB ports, PCI Express slots, and Gigabit Ethernet interfaces. This extensive connectivity ensures that users can easily expand and customize their systems according to specific application needs. The onboard Gigabit Ethernet ports provide fast network access, which is essential for data-intensive workloads.

Furthermore, the X8SIL, X8SIL-F, and X8SIL-V boast an efficient thermal design. These motherboards feature robust heat sinks and fan headers, which help maintain optimal operating temperatures, even under heavy workloads. This thermal efficiency is critical in extending the lifespan of components and ensuring consistent performance.

In summary, SUPER MICRO Computer's X8SIL, X8SIL-F, and X8SIL-V motherboards stand out with their strong performance, advanced management features, flexible storage options, and efficient thermal design. These characteristics make them ideal choices for businesses looking to build reliable and scalable data center solutions.
