1. Ways to save money: Start up application first

"If you want to do a good job, you must first sharpen your tools." IT procurement is not only to help improve internal work efficiency and save costs, but also reasonable IT equipment can help to obtain greater benefits, especially for start-ups that focus on services. At present, in the context of Internet+, it can be said that all people talk about entrepreneurship and everyone is the boss, but it is almost the consensus of all entrepreneurs to know what is easy and do what is difficult. As a startup company, how to balance the relationship between equipment performance and cost under the condition of "poor money".

For many start-ups, the so-called procurement is nothing more than making a list to go around Zhongguancun, looking for prices among various product advertisements, and deciding the final procurement equipment and scheme through a balance point. In addition to the daily expenses of rent, water, electricity and manpower, IT equipment The server How to spend the purchase money is one of the most important "money" scenarios for entrepreneurs.

1. What factors do start-ups value when purchasing? (Price, brand, configuration, appearance, service, etc.)

2. What are the common IT applications of start-ups (within 2 years)? (web, mail, terminal, database, etc.)

3. What do start-ups pay most attention to when purchasing IT infrastructure solutions? (Ease of use, rapid deployment, reliability, scalability, etc.)

Here we mainly explain the requirements of start-ups for server procurement applications. After understanding the different requirements of start-ups, the next step is to configure the corresponding server for procurement. Compared with large and medium-sized enterprises, the IT architecture system of start-ups is often weak, and their server deployment is usually highly oriented to the actual business.

The way to save money: Start up application first

When it comes to start-ups, the first impression is that they are relatively weak in scale and strength, which is mainly reflected in financial strength. At the initial stage of development, the company was small in scale and business volume, and would not invest too much money in information construction. The purchase server generally pursued TCO from the perspective of application based on the principle of "less money, more work".

In addition, in some non IT entrepreneurship, the lack of strength also reflects the lack of IT talents. In general, when selecting server deployment, it provides suggestions on server availability, manageability, and scalability. In particular, the initial purchase cost only accounts for a part of the total cost of ownership of the enterprise, while the later hardware upgrade costs, management and maintenance costs, etc. will be close to or exceed the initial purchase cost. Therefore, only products with high cost performance, easy management, stability and reliability under the premise of application business are more suitable for start-ups and can reduce the total cost of ownership for enterprises.

At present, the most basic server applications include mail server, Web server, terminal server, file server, database server, etc. For different server configuration priorities, the configuration requirements of these applications will be analyzed one by one. Due to different business applications, the price will vary (no specific price will be provided). Here, only a reference configuration scheme is provided for enterprises.

2. Build mail, terminal and file server application solutions

Mail server scheme

Generally speaking, start-ups' mail servers do not require high processor performance, but they have certain requirements for network subsystems and memory because they need to support a certain number of concurrent connections. The mail server software also has a high demand for memory, and requires a large storage space for mail and files. However, for start-ups, Cmail The number of servers is generally less than 100, so the requirements for server configuration are not high. An entry-level server can fully carry the needs of clients. The hardware requirements of the mail server are memory, disk, network system and processor.

Dell entry-level tower server

According to the degree of hardware, a mail server software should be selected first to build a corporate mailbox server. The server configuration should be determined according to the number of users of the mailbox. Considering the future growth of the number of users (200-300 mail users), certain configurations should be met:

● Server software: Winmail Exchange、Coremail、U-Mail、TurboMail、 E-mail, etc.

● Server hardware: medium and low-end server, Xeon E3, 8G memory or more, four 146GB SAS hard disks or more, set as RAID5, and equipped with one gigabit network card.

● System requirements: Linux operating system is recommended for stability, but small enterprises with simple operation mostly use Windows version.

Terminal server scheme

In the era of mobile internet, client application has become a trend. The terminal server applies all the load of the client to the server, so it has certain requirements for the server's processing capacity. The processor should be able to carry a certain number of concurrent requests and provide fast response speed. High speed and large capacity memory can improve the response speed of the terminal server, and it is also one of the necessary conditions to improve the overall performance.

In addition, because the data transmission volume between the terminal server and the client is not very large, the network requirements are not very high, and the terminal server is mainly used in the internal network of enterprises. The internal high-speed LAN environment can fully meet the bandwidth requirements between the terminal server and the client. The priority of terminal server for hardware requirements is processor, memory, disk and network system.

● Server hardware: quad core tower or 1U dual rack server, Xeon E5600 or above, 4G memory, low hard disk capacity requirements, equipped with dual gigabit network card.

● Server software: Windows Server 2003/2008 and above

File server scheme

As far as file servers are concerned, enterprises are used to manage files and share some PPT, software, etc. Users need to download or upload files through sharing or FTP. The data transmission between the server and the user's disk has certain requirements for the network bandwidth, otherwise it will affect the user's file sharing and access experience.

In addition, file sharing has certain requirements for the capacity and speed of the disk subsystem. The disk with high speed and large capacity cache can effectively improve the speed of file transfer on the disk. At the same time, large capacity memory can reduce the number of times to read and write to the hard disk, provide a buffer for file transmission, and improve the data transmission speed. To sum up, the priority of file server hardware requirements is network system, disk system and memory.

● Server software includes server-u, Microsoft FTP Server, etc.

● Server hardware: dual way four core server, Xeon E5600 and above, 4G memory and above. Due to the increase in data volume, it is recommended to use a large capacity TB hard disk, which can be set as RAID5 to effectively protect data, and equipped with dual gigabit network card.

● System requirements: Windows Server 2008 R2 and above.

The above relevant application scheme configuration is only for reference, and the configuration and software use need to be adjusted according to the special requirements in different businesses. The scheme is applicable to the general business application requirements of start-ups.

3. Build web and database server application solutions

Web server scheme

Different website content has different hardware requirements for the Web server. The static Web has different hardware requirements for the server from high to low: network system, memory, disk system, CPU. If the Web server mainly performs intensive computing (such as dynamically generating Web pages), then the hardware requirements for the server are in the following order: memory, CPU, disk subsystem, and network system.

HP Proliant Rack Server

● Server hardware: dual rack server, Xeon E5, 4G memory, low requirements for hard disk capacity (SAS hard disk is selected for video), set as RAID5, and equipped with dual gigabit network card.

● WEB server software: Apache and Microsoft IIS. IIS is mainly aimed at small Internet environment and runs 2000/XP/2003 Server platform and above, while Apache has Windows, Linux and Unix versions. In terms of performance, Apache+PHP has a slight advantage over Windows NT+IIS.

Database server scheme

As the core business application of the enterprise, the database server has high requirements on all aspects of the system. It needs to handle a large number of random I/O requests and data transmission, and has certain requirements on the computing ability of memory, disk and CPU. In terms of memory, the database server needs high capacity and high speed memory to save the time for the processor to access the hard disk and improve the response speed of the server.

IBM System x Rack Server

For processor performance, the database server needs to query according to conditions, meet the needs of a large number of users to query at the same time and respond quickly. In terms of disks, the high-speed disk subsystem can also improve the query response speed of the database server. At present, many large devices are gradually transitioning to the mixed use of HDD and SSD, which helps to improve disk I/O, reduce costs, energy consumption and ease of use.

With the continuous development of processor technology, it not only provides comprehensive process technology and RAS features to help users quickly and accurately query, but also enables millisecond level statistics and analysis. For start-up users, the mainstream two-way Xeon chips can fully meet the demand. As mentioned above, the database server is mainly used to store, query, and retrieve information within the enterprise, so it needs to be matched with a dedicated database system, which has high requirements on server compatibility, reliability, and stability.

● Server software includes ORACEL, MS SQL, etc.

● Server hardware: rack server, dual quad core Xeon E5 processor and above, SAS hard disk, RAID 1 or RAID5, equipped with dual gigabit network card.

● System requirements: Windows Server 2003 and above. Specifically, Windows 2003 Server Enterprise Edition is highly efficient and can be considered for SQL Server users.

From the application point of view, in combination with the different technical specifications of the server, relevant scheme configuration instructions are provided. Among them, the server requires high performance and fast response speed, such as WEB, database server, etc., and dual rack server is recommended. However, the storage space of the server is large (such as video, FTP server, etc.), the processing speed and data storage of the server are not high, but the stability and security are high. For example, tower servers are recommended for file and mail server applications, and we hope to provide better solutions through the following feedback.
