Enterprises often face a bunch of server configuration parameters at a loss when purchasing servers. How can users choose the appropriate server based on the data provided by the manufacturer? Below is a list of common configuration data for everyone:
nine hundred
1. Is Dual Path Equal to Dual Core
Regardless of the server's single, dual, four, or even eight paths, of which& Ldquo; Road& Rdquo; Both refer to the number of physical CPUs in the server, which is the number of CPU slots on the server motherboard< Br/>
A dual core processor encapsulates two CPU cores within a physical CPU, which has the advantage of allowing users to have stronger performance without increasing costs. Moreover, it can significantly reduce the performance to power ratio, which has a positive significance for enterprise users to save usage costs< Br/>
2. The difference between Xeon and Pentium
(1) Since the beginning of the Intel Pentium 4 processor, it has been classified as a personal processor. Users cannot use two Pentium 4 processors to construct a 2-way server system, and instead develop Xeon processors with higher computational efficiency. Xeon processors are currently divided into Xeon DP and Xeon MP< Br/>
(2) The second level cache is different. The maximum second level cache is between 1MB and 16MB, while the second level cache of P4 is between 512KB and 1MB. The capacity of the second level cache is also an important factor determining the server's processing efficiency. The Xeon series CPUs mostly have 604 interfaces, while the P4 CPUs mostly have 478 pin or 775 architecture< Br/>
3. Several types of servers
According to the external structure, it can be divided into three types: tower servers, rack servers, and blade servers< Br/>
(1) Tower servers
A typical tower server chassis is similar to the commonly used PC chassis, while a large tower chassis is much thicker, and overall, there is no fixed standard for overall dimensions. The functions and performance of tower servers can basically meet the requirements of most enterprise users, and their costs are usually relatively low, so they have a very wide range of application support< Br/>
(2) Rack mounted servers
Rack mounted servers are a type of server with a standard width of 19 inches and a height ranging from 1U to several U, designed to meet the intensive deployment of enterprises. Placing the server on a rack is not only beneficial for daily maintenance and management, but may also avoid unexpected failures. Placing the server does not take up too much space, and the connecting cables can also be neatly packed into the rack. The power and LAN cables can all be laid in the cabinet, reducing the accumulation of connecting cables on the ground and preventing accidents such as kicking off wires< Br/>
(3) Blade servers
Blade servers are a high availability, high-density, and low-cost server platform designed specifically for special application industries and high-density computer environments, where each block is; Ldquo; Blade& Rdquo; It is actually a system motherboard, similar to individual servers. In this mode, each motherboard runs its own system, serving designated different user groups, without any correlation between them. However, system software can be used 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< Br/>
