• Intel Xeon

  Intel 系列处理器。

  Intel Xeon is a distinct product line from the similarly-named Intel Xeon Phi.

  From , Xeon is a brand of x86 microprocessor designed, manufactured, and marketed by Intel, targeted at the non-consumer workstation, server, and embedded system markets.

  It was introduced in June 1998.

  Xeon processors are based on the same architechture as regular desktop-grade CPUs, but have some advanced features such as :

  1. support for larger amounts of RAM, larger cache memory and extra provision for enterprise-grade reliability, availability and serviceability (RAS) features responsible for handling hardware execptions through the Machine exception (MCE)
  2. some also support multi-socket systems with two, four, or eight sockets through use of the Quick Path Interconnect (QPI) bus

• clock rates vs. core counts

  Some shortcoming that make Xeon processors unsuitable for most consumer-grade desktop PCs include lower clock rates at the same price point(since servers run more tasks in parallel than desktops, core counts are more important than clock rates)

  (时钟频率，也就是常说的计算机频率), typically refers to the frequency at which the clock generator of a processor can generate pulses, which are used to synchronize the the operations of its components, and is used as an indicator of the processor’s speed.

  Clock generator

  From , a clock generator is an electronic oscillator (circuit) that produces a clock signal for use in synchronizing a circuit’s operation.

  Electronic oscillator

  From , an electronic oscillator is an electronic circuit that produced a periodic, oscillating electronic signal, often a sine wave or a square wave.

  Oscillators convert direct current (DC) from a power supply to an alternating currect(AC) signal.

  Electronic circuit

  From , electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow.

  To be referred to as elctronic, rather than electronical, generally at least one active component must be present.

  Clock signal

  From , a clock signal (historically also known as logic beat) oscillates between a high and a low state and is used like a meronome to coordinate actions of digital circuits.

• ECC DDR4 DIMM

  From , Double Data Rate 4 Synchronous Dynamic Random-Access Memory, offically abbreviated as DDR4 SDRAM, is a type of synchronous dynamic random-access memory with a high bandwidth(‘double data rate’) interface.

  ECC(), Error-Correcting Code memory, 指能够实现错误检查和纠正错误技术的内存。ECC广泛应用与服务器，本身并不是一种内存型号，也不是一种内存专用技术，它是一种广泛应用于各种领域的计算机中的纠错技术。

• RDIMMS/LRDIMMS

  Dual In-Line Memory Module (DIMM) : RDIMMs vs. LRDIMMs.

  LRDIMM : Load-Reduced DIMM

  RDIMM : Registered DIMM

  UDIMM : Unbuffered DIMM

• MT/s

  From , transfer per second and its more common secondary terms gigatransfers per second (abbreviated as GT/s) and megatransfers per second (MT/s) are informal language that refer to the number of operations transferring data that occur in each second in some given data-transfer channel.

  It is also known as sample rate, the number of data samples captured per second, each sample normally occuring at the clock edge.

  MT/s is a measurement of bus and channel speed in millions of ‘effective’ cycles per second.

  MHz/s is used to measure the transmission speed of electronic devices.
