Xiao Bian Teach You An Initial Understanding Of Blade Servers And Technologies
In business and enterprise networks, generally adopt C? S model, which is “the client? Server” mode, according to authoritative forecasts, the future network development has presented a centralized computing trend. The emergence of the data center server configuration density higher and higher demands, it is in such a situation, the individual performance of the server to break the limit, a new generation of clustered servers?? Blade server, a timely. In business and enterprise networks, generally adopt C? S model, which is “the client?

Large-scale computing and network servers with parallel processing capacity needs on the further development of the “collective power” cast a strong capacity for blade servers have become increasingly high regard. Blade server technology in recent years the development of a major breakthrough, its significance is much greater than the frequency of the upgrade processor and memory, hard drives and other storage media surge capacity, why the blade server has such an important position, following the writer’s According to his own knowledge, combined with some relevant technical information as we explain:
First of all, in business and enterprise networks, generally adopt C? S model, which is “the client? Server” mode, according to authoritative forecasts, the future network development has presented a centralized computing trend. The emergence of the data center server configuration density higher and higher demands, it is in such a situation, the individual performance of the server to break the limit, a new generation of clustered servers?? Blade server, a timely.
Why is it called blade servers, this is based on the characteristics of product form is named, because the composition of the blade server modules are flat, flat shape, looks like a blade, so when the product manufacturer also introduced logical name it so; blade server, we usually say is that the standard height rack chassis can plug in multiple cassette server unit (ie blades, which in fact is in line with industry standards board, on which there are processors, such as memory and hard drive and install the operating system, so a “blade” is a small server.), which combine a picture of the blade, for data exchange and sharing of software in the system can work under the coordination of simultaneous into a new type of high availability and high-density servers.
Features: Overall, blade servers have the following characteristics, but also about the advantages of its location is:
1, high-density computing High-density blade server is the biggest feature, regardless of their work areas for high or low, just from the calculated density, is still second to none. Of course, the computing power not only decided by the number of processors, a pile of a single system, a powerful high-performance computing power of computers is not because only 4 to 8 processors reduced. So what blade servers rely on to capture the market? In general, both the operating system or application software, have significantly lagged behind the pace of hardware development, Web and other distributed applications closer to distributed computing?? The same time a large number of process parallel, and the calculation of a single process and very low processing requirements, are consistent emphasis on high-density blade server distributed computing architecture. For blade servers, the increased compute density data centers can be used to make less room to serve more customers, but also allow Web site hosting costs lower.
2, distributed computing Even with the group-level server
than as a single blade server blade configuration and a disadvantage, so they need load balancing / clustering software can be achieved with the use of good results for high-density areas is limited to the distributed computing environment: IDC, Web, domain name resolution and so on.
