How to choose IDC user virtualization server

Internet Data Center (IDC), which is developed along with the growing needs of the Internet, is an Internet content provider (ISP), enterprise, media And various types of websites provide large-scale, high-quality, secure and reliable professional server hosting, space rental, network wholesale bandwidth and ASP, EC and other services. So, in a sense, it evolved from the ISP's server hosting room.

IDC is not only the center of data storage, but also the center of data circulation. It provides a high-end data delivery service, which is a high-speed access service. It can be said that it appears in the most concentrated place of data exchange in the Internet. So, what kind of virtualization server is suitable for IDC? In this article we will introduce virtualization server selection for IDC users.

First, the application characteristics of the IDC room

Evaluation of the IDC room level, in addition to the network resources, is equipped with hardware conditions. Network bandwidth can be seen or can be felt, while in hardware and facilities, some considerations are computer room construction, area, security monitoring, power supply, and disaster prevention capabilities; the other part is hardware devices such as servers and firewalls.

The selection of server devices is crucial, and it is inevitable to consider how to improve the high performance, high availability, high computing power, good scalability, and load balancing of servers. problem. Due to the differentiation of IDC network structure design, it is generally divided into front-end server, application layer server and back-end database server and storage server.

Each layer of server application is different, and the selected server is different. For example, the front-end server directly interacts with different application requirements of users, such as Web, FTP, email, newsgroups, and cache and security applications. From the perspective of performance, reliability, and manageability, the server should prefer the rack. The middle-tier application server mainly deploys business logic, such as ERP, e-commerce, etc., requires high-performance, highly computing servers, and also supports load balancing through proprietary hardware switching devices. The back-end data support server deploys large databases, and the SAN intelligent storage area network is responsible for centralized storage and backup of data.

From the level and scale of IDC equipment room, there are carrier-class computer room, A-class or backbone node level, network company level, space rental-type machine room, and internal data center. It can be said that IDC machine room The models are different, and the models of the servers vary widely.

Considering the type of server, it is generally recommended to choose a rack server. Because of the small size and manageability of the rack server, IDC can take advantage of the limited space to place the largest number of servers. In addition to being small and easy to stack, rack-mounted servers are easy to manage and maintain, providing high-density computing power with good redundancy and scalability.

The above is only an analysis of some considerations for server selection in different application levels in the IDC room, combined with today's mainstream virtualized servers. Servers in the front-end and middle-application layers are common in the marketplace. While the backend supports large databases, using SAN storage and storage servers, we do not recommend this in this article.

two, the IDC room distal end server virtualization server selection


IDC room, and is usually based access server, in the conventional machine vendors The rack server is available in 1U and 2U types.

HP has launched a virtualization server for the data center, such as the new generation of G7 series servers based on the Intel Xeon 5600 platform, multi-node server ProLiant DL2x170h G6, these models users can query on HP's official website . And in the virtualization server on the middle-tier application side, HP's model performance is even stronger.

The C1100 in Dell's Power Edge C-Series servers is a product for high-density data centers and cloud computing centers. The two-socket 1U rack is designed to save space and meet the needs of Web, virtualization and data center analysis, while the Xeon 5600 provides sufficient performance.

domestic manufacturers to do more thorough in the front-end access server. Inspur NF5280 M2 can be used as a web access server, mail server, database server, video on demand server, etc. It is also suitable for business applications such as IDC/ISP/ICP/ASP and information carriers. Designed for Internet service providers, Lenovo's SD 2104X is ideal for integrated portals, online video, blogs, personal spaces on social networking sites, and much more. The R510G7 and R520G7 are also two data center optional models for the Internet, online games, video sites, and unattended SMBs. Dawning's I620r-G and I640r-G are designed for demanding industrial data centers and remote enterprise environments.

IV. IDC server market for the supply and price


the recommended products and models, can be found in markets and channels, product prices after nearly a year of adjustment, the already very reasonable. For the multi-node servers of various manufacturers, it is generally not shipped in the regular channels, and is sold directly by the salesperson of the manufacturer. Between different brands and dealers, users need to evaluate their own room conditions, as well as application needs and trade-offs.




In fact, IDC equipment room requirements for the server is relatively strict, not only need to consider the use of the equipment room and the service object, the most critical is the performance, energy consumption, scalability of the server Excellent selection of factors such as reliability. The birth of virtualized server technology ensures that applications are deployed to ensure that systems, applications, and data are continuously available, reducing risk, reducing costs, and improving the flexibility of the entire IT environment.
