Dual vs PC: Teach you how to tell a fake server

Because of the lack of enterprise-class product contact to understand, many users, a contact server, Web page production, such as office information preparation, can not help but some confused. Not only that, the current chaotic medium and low-end server market also allows buyers to sigh, especially true and false server discrimination often let these laymen overwhelmed.

With the continuous deepening of the server differentiation and information process, the development of small and medium-sized enterprises can not be separated from the construction of local area network, server and other basic information needs. But at the same time, most of the requirements of small and medium-sized servers are general-purpose, performance requirements are very general, so manufacturers for such users, removed the complex calculation part, the introduction of low-end server product line. Inexpensive million-tier low-end servers are also being pursued by many new small businesses.

But through the reporter to know, now most users often equate the PC with the server, the dispute that their servers are from the market to spend tens of thousands of yuan, or even tens of thousands of yuan to assemble. For a time, the authenticity of the server has become a hot topic in the industry nowadays.

In the interview, the reporter took the opportunity to open several so-called "server", its built-in does not have any can be called "Server" reason. is only a large chassis, the motherboard is big enough, installed one or two hard drives, can not find any and ordinary PC has any obvious difference between the place, is actually a real PC, and the price is far in the same file PC. For example, a brand TS430 model server, its configuration is a single power e3-1220 (3.1G)/2g/500g SATA, although the brand, but in fact just a high-end PC. According to industry sources, high-end PC is not a true sense of the server, it is clear that they do not meet the real server's standard configuration.

In the information system, the server mainly applies to the database and the Web service, while the PC mainly applies to the multimedia technology and the network terminal, the fundamental application difference decides the server has the more powerful storage ability than the PC, the quicker recovery function and the broader expansion space, At the same time the server must also provide the PC does not have the data backup function. These specifications are a necessary element of a server, but also to some extent, to differentiate between PC and server standards. Specific performance in 4 areas, the need for 2 and above the number of CPUs, excellent performance, scalability, availability, usability, manageability, and so on.

Two-way is the basic server

In the server market, a single server as a low-cost, stable performance of the product has been a lot of entry-level users attention, in the past is almost a synonym for entry-level servers, And the single server is also due to the stability and manageability of high-end PCs as well as to the low cost of multiple servers by the SME user attention. However, in the current market, single-way server life is not easy, the reporter and a number of dealers have communicated, they agree that now a single path server market is relatively light, whether the channel market or retail market are shrinking, and some dealers are outspoken said "Now we do not say a single way, We prefer to sell two roads.

Indeed, as server technology continues to evolve, manufacturing technology continues to evolve, manufacturing costs are falling, and previously expensive servers are now becoming commonplace, as is the reason why few people today use a better PC to serve as servers. Comparatively speaking, the dual server performance is excellent, the upgrade space is big, the price is also relatively inexpensive, especially the double tower server becomes the most suitable choice for most small and medium-sized enterprises. Choose Dual server, whether tower or rack, enterprises do not need huge sums of money and a large technical team can achieve the entire information system operation and upgrade. such as Dell T610 Server, Dawning day wide A440-G servers are dual-road 4U Tower departmental server, with fast processing speed, strong availability, easy management, high expansion, low power consumption and low noise characteristics, can adapt to a variety of important task environments, for users from 32-bit applications to 64-bit application smooth transition to facilitate, Can greatly save the enterprise information system upgrades the cost of expansion.

Scalability is a necessity for the server

First, the server should be highly scalable, extensible refers to the server's hardware configuration, such as memory, adapters, hard disk, processor, etc., can be based on the original is very convenient to increase as needed. The server has more PCI, PCI and other slots, more drive support and larger memory expansion capabilities. Provide redundant power supplies, redundant fans, so that the user's network expansion, the server can also meet new requirements, protect the user's investment.

There are many brands that have a "high scalability" concept in terms of server extensibility, which is mainly concentrated in medium and low-grade servers. Dawning A440-g inherits the high stability and high scalability of the dawning server, which contains integrated RAID0/1/5 controllers, troubleshooting tools, hot-swappable support, remote management control, and standard and scalable IPMI 2.0 support to ensure easy installation, management, maintenance, Really do use worry-free.

Reliability and practicality are two major genes in the server

The availability of the server is in fact the requirements of the server has high reliability, with high stability, do not panic from time to time, out of trouble, as little as possible downtime to be repaired phenomenon. The server is very important because it requires continuous work in most cases, and it requires a quick way to recover the service in the event of a failure. When the PC occurs the system failure, generally uses restores the registration form, the reinstall system and so on the way to eliminate the fault and restores the system the normal operation, the data loses the loss also limited to the single computer. Server is completely different, many important data are stored on the server, many network services are running on the server, once the server failure, will lose a lot of data, resulting in the loss is difficult to estimate. Therefore, the requirements for server reliability are very high.

The utility of the server is from the server's processing capacity, in most cases, the server requires a high computational processing capacity, processing efficiency is high, so the selected configuration is typically for the server specifically developed, especially the CPU and motherboard, to select the server-specific. The server is serviced for other computers on the network. Because the server wants to provide its data, hardware to the network share, when running some applications to handle a large number of data, it is likely to need to respond to dozens of, hundreds of or even thousands of computer requests, so the server should be faster than the normal PC speed, Bandwidth is also much wider. At this point, the speed of the hard drive also has higher requirements, so the server hard disk usually select the SCSI interface. The capacity is certainly much larger than the average PC.

Manageability is the security of the server

The manageability aspect of the server not only refers to the software aspect, also needs to have the certain management performance in the server hardware aspect, like the pre-alarm function, the system monitoring function and so on. The management performance of server hardware can be achieved through ISC (Intel Server Control,intel server Control) technology. EMP (Emergency Management port, Emergency management ports) technology is also a server management technology. This is what the PC does not have.

Through the above comparison, it is not difficult to see that the server and PC are strictly defined, and the function of the server is not possible to replace the PC. In the server market, some channel vendors will high-end PC palmed low-end server, this confusion will eventually be the market and consumers despise.

At the same time, as the server technology matures, domestic and foreign server brand manufacturers have launched small and medium-sized enterprises to apply Low-cost server, at the same time the top domestic server brand, to the branch of the dawn as the representative of the Independent research and development of information industry companies also tailor-made for small and medium-sized enterprises to make more cost-effective server, and up to 5 years of warranty. As users can be assured to choose the brand server at the same time, in the long-term interest, combined with their own needs to choose the most suitable for their use of the server products.
