Lenovo ThinkSystem SR650 Xeon Silver 4208 Slide Rail

Processor
Processor manufacturer The manufacturer that produced the processor.	Intel
Processor family A family of processors is a group of processors produced by one company over a short period of time e.g. Intel Pentium processors.	Intel Xeon Silver
Processor model The model number for the processor in a computer.	4208
Processor frequency The speed that the microprocessor executes each instruction or each vibration of the clock. The CPU requires a fixed number of clock ticks, or cycles, to execute each instruction. The faster the clocks rate, the faster the CPU, or the faster it can execute instructions. Clock Speeds are usually determined in MHz, 1 MHz representing 1 million cycles per second, or in GHz, 1 GHz representing 1 thousand million cycles per second. The higher the CPU speed, the better a computer will perform.	2.1 GHz
Processor boost frequency The turbo boost is an automatic, managed accelleration of the processor when one of the cores is overloaded.	3.2 GHz
Processor cache	11 MB
Motherboard chipset The chipset connects the microprocessor to the rest of the motherboard.	Intel® C624
Number of processors installed Number of processors in the product.	1
Execute Disable Bit
Embedded options available

Memory
Internal memory A computer's memory which is directly accessible to the CPU.	16 GB
Internal memory type The type of internal memory such as RAM, GDDR5.	DDR4-SDRAM
Memory clock speed The frequency at which the memory (e.g. RAM) runs.	2933 MHz
Memory layout (slots x size) The slots and size of the memory for the CPU.	1 x 16 GB

Storage
Optical drive type An optical drive uses laser to read optical discs such as CDs, DVDs and Blu-Ray. Some types of optical drive are: CD ROM drive, CR-RW (CD writer) drive, DVD-ROM.

Graphics
On-board graphics card Graphics hardware which is built into the motherboard or CPU, as opposed to a separate graphics adapter (video card). On-board graphics uses CPU and RAM for graphics processing.
On-board graphics card model "Graphic adapter" is the hardware that produces images on a display. "On-board" means that the graphics adapter is intergrated inside the motherboard.	Matrox G200e
Maximum graphics card memory Graphics memory is determined by the (graphic) processor. Graphics memory is often shared with system memory so that it varies depending on the amount of system memory installed and system load.	16 MB

Network
Ethernet LAN An Ethernet LAN (Local Area Network) interface is present, for a wired conection via a cable.
Cabling technology Type of cable technology performance.	10/100/1000Base-T(X)

Ports & interfaces
USB 2.0 ports quantity Number of USB 2.0 ports (connecting interfaces) in the device. USB 2.0 was released in April 2000 (now called "Hi-Speed"), adding higher maximum signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s or 280 Mbit/s), USB 2.0 ports are usually black.	1
USB 3.2 Gen 1 (3.1 Gen 1) Type-A ports quantity	3
VGA (D-Sub) ports quantity Number of VGA (D-Sub) ports (connecting interfaces) in the device. The VGA (D-Sub) connector is a 15 pin connector between a computer and a monitor. It was first introduced in 1987 by IBM.	1

Design
Chassis type The type of rigid framework onto which is the hosuing for device components.	Rack (2U)
Product colour The colour e.g. red, blue, green, black, white.	Black, Metallic
Rack mounting The type of mounting that can position devices in a shelving system (rack).
Redundant fans support
Rack rails

Processor special features
Enhanced Intel SpeedStep Technology
Intel Virtualization Technology for Directed I/O (VT-d) <b>Simplify Virtualization and Reduce Overheads</b> Intel® Virtualization Technology (Intel® VT) helps make virtualization practical by eliminating performance overheads, reducing complexity, and improving security with hardware assistance. Virtualization allows multiple workloads to share a common set of resources so that a variety of workloads can co-locate while maintaining full isolation from each other.
Intel Trusted Execution Technology
Intel VT-x with Extended Page Tables (EPT)
Intel TSX-NI
