How do I configure the SME server?

Prior to the "Quest for SME server performance requirements" introduced in the small and medium-sized enterprises for the performance requirements of the server, in understanding the requirements of server performance, then it should be configured to the corresponding server.

Compared to large and medium-sized enterprises and IDC Data center, SMEs are often weak it architecture systems, usually its server deployment to the actual business is very strong. As a result, we know more about databases, mail, multimedia, printing, terminal servers, and so on that are more common and close to real needs.

So, what are the metrics for the servers that consider these specific applications? Are the configurations all the same for different application servers? This article will introduce you to this.

Small and medium-sized enterprises in the size and strength are relatively weak, the most mainly reflected in the financial strength. In the initial stage of enterprise development, the company scale is small, business volume is small, information construction needs are not strong, the effect is not obvious, so in the initial phase of the information construction will not invest too much money, procurement server generally in the spirit of less money, more work principle, the pursuit of capital return.

In addition, the strength of the deficiencies also reflected in the corresponding lack of IT personnel. Dedicated IT staff can add an extra amount of money, and in general, small, smaller businesses typically have little or no dedicated IT staff for cost reasons. It is worth mentioning that the traditional focus on investment costs, now more and more attention to operating costs. When choosing a server deployment configuration, an enterprise cannot blindly pursue low costs while ignoring server availability, manageability, and scalability. The initial purchase cost is only a part of the total cost of ownership of the enterprise, and the hardware upgrade cost, management maintenance cost, personnel cost and so on may close or exceed the initial purchase cost. Therefore, low prices, easy to manage, stable and reliable server products are more suitable for small and medium-sized enterprises, can reduce the total cost of ownership.

Message and Web server configuration considerations

At present, the most basic server applications are file servers, database servers, mail servers, Web servers, multimedia servers, terminal servers, and so on. These applications to the server configuration requirements of different emphases, according to different applications procurement of different configurations of servers can be fully utilized server resources, to avoid the waste of funds and server resources. In the following will each of these types of server configuration requirements of the focus of analysis for the enterprise to provide a reference.

Mail server

In today's era, few companies do not use mail to work. Generally speaking, the mail server does not have high processor performance requirements, but due to support a certain number of concurrent connections, there are certain requirements for the network subsystem and memory. The mail server software also has a higher demand for memory. At the same time, the mail server needs a large storage space to store mail and some files, but for small and medium-sized enterprises, the number of enterprise mailboxes in general only hundreds of below, so the server configuration requirements are not high, an entry-level server can fully host hundreds of mail client needs. The level of hardware requirements for the mail server is memory, disk, network system, and processor in turn.

Web server

Different Web site content for the requirements of the Web server hardware is also different, if the Web site is static, the Web server hardware requirements from high to Low: network system, memory, disk system, CPU. If the Web server is focused on intensive computing (such as dynamically generating web pages), the server hardware needs are: memory, CPU, disk subsystem, and network system.

Terminal Server

The terminal server, because it adds all the load on the client to the server side, therefore, the processing capacity of the server has certain requirements, the processor to be able to host a certain number of concurrent requests, provide rapid response speed, if the processing capacity is not enough, easy to cause the server slow response, software running errors or even downtime. High-speed, large-capacity memory can improve the response speed of the terminal server, but also one of the necessary conditions to improve the overall performance. Because the terminal server and the client data transfer is not very large, so the network requirements are not very high, and the terminal server is mainly applied to the enterprise internal network, the internal high-speed LAN environment can fully meet the Terminal server and client bandwidth requirements.

Customers who use Terminal Services can access the server remotely as a graphical interface, and can invoke applications, components, services, and so on in the server. The priority of a terminal server for hardware requirements is the processor, memory, disk, and network system in turn.

File and database server configuration considerations File Server

A file server is an intranet server that uses the network to provide users with access requests and service delivery, and file servers are used to manage shared files. In the enterprise needs to share some files, such as PPT, software and so on, users need to share the way or ftp file download or upload. The file server hosts bulk data transfer between the server and the user disk. Therefore, the file server is highly dependent on the network, and the quality of network bandwidth directly affects the user's file sharing and access experience.

In addition, file sharing will naturally involve disk read and write operations, therefore, the disk subsystem capacity and speed have certain requirements. Select High speed, high interface speed, high-capacity cache disk, and build disk array, such as RAID 0, RAID 5, can effectively increase the speed of the disk system transfer files. In addition, the large capacity of memory can reduce the number of read and write hard disk, to provide buffer for file transfer, improve data transmission speed. In summary, the priority of the file server for hardware requirements is network system, disk system and memory.

Database Server Topology

Database server

Database server is very high in all aspects of the system, to handle a large number of random I/O requests and data transfer, the memory, disk and CPU computing power have certain requirements. On the memory side, the database server needs high speed memory to save the processor time to access the hard disk and improve the server's response speed. Today's Xeon processors generally support multiple memory channels, each of which can support multiple memory slots, and memory support is already strong for cloud computing's work virtualization applications and private cloud deployments. To this end, in the memory of this piece, the current memory technology and product development is very mature.

The database server also has a high demand for processor performance. The database server needs to query based on requirements, and then feedback the results to the user. If the query request is very much, such as a large number of users at the same time, if the server's processing capacity is not strong enough to handle a large number of query requests and answer, then the server may be slow to respond or even panic.

On the disk side, high-speed disk subsystem can also improve the database server query response speed, which requires the disk with high-speed interface and speed, many large machines are gradually transition to the HDD and SSD plug-in applications, which can greatly improve disk I/O, reduce costs and energy consumption, improve ease of use.

The database server also has a high demand for processor performance. The database server needs to query based on requirements, and then feedback the results to the user. If the query request is very much, such as a large number of users at the same time, if the server's processing capacity is not strong enough to handle a large number of query requests and answer, then the server may be slow to respond or even panic. The current processor technology development is very advanced, not only can quickly and accurately query, and can realize the millisecond level of large data query, statistics, analysis. For small and medium-sized users, the use of the mainstream of the two-way, four-way Xeon Chip, can fully meet the demand.
