This article shows you what is the difference between the configuration data in the server, the content is concise and easy to understand, it can definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Enterprises are often at a loss in the face of a pile of server configuration data when renting a server. what does the data in the configuration mean and what kind of help can be provided for my needs? these are all issues that enterprises consider when renting servers. Today, I would like to explain it to you in the way of question and answer:

Is a two-way equal to a dual core?

Answer: no

Regardless of the single-way, dual-way, four-way, or even eight-way server, the "path" refers to the number of physical CPU of the server, that is, the number of CPU slots on the server motherboard.

Dual-core processors encapsulate two CPU cores in a physical CPU, which has the advantage of enabling users to have stronger performance without much increase in cost. And it can significantly reduce the ratio of performance to power consumption, which is also of positive significance for enterprise users to save costs.

2 the difference between Zhi Qiang and Pentium

Answer: the core of the Xeon processor used on the server is basically the same as that of the ordinary P4 processor.

One of the differences is that the Intel Pentium 4 processor began to classify the Pentium 4 processor as a personal processor. Users cannot use two Pentium 4 processors to build a 2-way server system, but develop a highly powerful processor with higher computing efficiency. Xeon processors are currently divided into Xeon DP (* * supports dual processing) and Xeon MP (* * supports 8-way processing).

The second difference is that the secondary cache is different. The strong second-level cache is 1MB cache 16MB P4 the second-level cache is 512KB~1MB, and the capacity of the second-level cache is also an important factor that determines the server's processing efficiency.

The most powerful series of CPU is 604 interface, while the CPU of P4 is mostly 478pin or 775architecture.

Note: under the X86 architecture, in addition to using Intel Pentium and Xeon series processors, AMD also provides specialized processors for servers-Haolong Opteron,*** can support 8-way.

3 several types of servers

Answer: at present, according to the shape structure, the server can be divided into three types: tower type, rack type and blade type.

Tower server

The general tower server chassis is similar to our commonly used PC chassis, while the large tower chassis is much thicker, and generally speaking, there is no fixed standard for external dimensions.

Rack server

Rack servers are designed to meet the intensive deployment of enterprises, resulting in a server type with a 19-inch rack as the standard width, ranging from 1U to several U in height. Putting the server on the rack is not only conducive to daily maintenance and management, but also may avoid unexpected failures. First of all, placing the server does not take up too much space. Rack servers are neatly arranged in the rack and do not waste space. Secondly, the connecting cable can also be neatly put into the rack. Power cord and LAN cable can all be laid in the cabinet, which can reduce the connection lines accumulated on the ground, so as to prevent accidents such as kicking off wires.

The specified dimensions are the width (48.26cm=19 inches) and height (multiples of 4.445cm) of the server. A rack that meets this requirement is sometimes called a "19-inch rack" because it is 19 inches wide.

Blade server

Blade server is a HAHD (High Availability High Density) low-cost server platform, which is specially designed for special application industry and high-density computer environment, in which each "blade" is actually a system motherboard, similar to individual servers. In this mode, each motherboard runs its own system, serves a specified different user group, and is not related to each other. However, you can use system software to assemble these motherboards into a server cluster. In cluster mode, all motherboards can be connected to provide a high-speed network environment, share resources and serve the same user group.

What is 4 "U"?

Answer: "U" in the server field specifically refers to the rack server thickness, is a unit that represents the external size of the server, is an acronym for unit, and the detailed size is determined by the American Electronic Industry Association (EIA), an industry group.

The reason for setting the size of the server is to keep the server in the right size so that it can be placed on an iron or aluminum rack. There is a screw hole for fixing the server on the rack. Align it with the screw hole of the server and fix it with screws.

The thickness is based on 4.445cm. 1U is 4.445cm.2U is twice as much as 1U and 8.89cm. In other words, the so-called "1U rack server" is the product whose appearance meets the EIA specification and the thickness is 4.445cm.

5 what is the difference between a server and a workstation?.

The server provides all kinds of services to workstations, including network communication services, file sharing services, hardware sharing services, and various resource services. The workstation can also help the server to divert computing and other tasks while obtaining various resources of the server.

Servers and workstations are high-performance computers, but relatively speaking, the server focuses on data throughput, so it supports more peripherals (hard disk, IUnip O slot, etc.), while workstations focus on graphics processing capacity, so there are relatively few peripherals, but the use of specially designed for graphics processing architecture, the use of high-end display cards, support 3D image processing. Workstations are mainly used in various design and multimedia production fields.
