A by-product of the widespread use of computers-heat-has become the number one enemy of the enterprise data Center. Excessive heat can continue to "torment" the CPU, "torture" the processor, reduce computer efficiency, and increase the burden of cooling systems, and ultimately consume more power. As the server cabinets in the data center become more dense, the temperature is hotter than ever, and the cooling problem becomes more severe, and the entire IT industry struggles to avoid data center paralysis caused by the overheating of the server. Using water cooling method is one of the solutions, so ...

This user account can only be dedicated to ...

SMP English is all called symmetrical multi-processing, meaning "symmetric multiprocessing" refers to the collection of a set of processors on a computer-that is, multiple CPUs, shared memory subsystems between CPUs, and bus structures.     It is a widely used parallel technology in the relative asymmetric and multi processing technology. In this architecture, a computer is no longer composed of a single CPU, while the operating system is run by multiple processors ...

The so-called Blade server (which is precisely called a blade server) means that multiple, modular server units can be plugged into a standard, rack-mounted chassis to achieve high availability and high-density. Each "blade" is actually a system motherboard. They can start their own operating system via "onboard" hard disk, such as Windows nt/2000, Linux, and so on, like a separate server, in which each motherboard runs its own system ...

The rapid growth of the Internet makes multimedia network servers, especially the http://www.aliyun.com/zixun/aggregation/17117.html ">web servers, face a rapid increase in the number of visitors, Network servers require the ability to provide a large number of concurrent access services. For example, Yahoo receives millions of requests per day for access, so CPU, I/O processing capacity will quickly become a bottleneck for servers that provide large-load Web services. &n ...

What is multi-core technology? Multi-core refers to the integration of two or more complete compute engines (kernels) in one processor. The development of multi-core technology stems from the understanding of engineers that simply increasing the speed of a single core chip generates too much heat and does not bring about performance improvements, as previously http://www.aliyun.com/zixun/aggregation/2578.html "> This is the case with the processor product. They realized that at that rate in the previous product, the heat generated by the processor would soon exceed the surface of the sun. Even if ...

What is Cluster? There are two common Cluster (clusters) architectures, one is Web/internet Cluster system, which is to place data on different hosts, that is, multiple hosts are simultaneously responsible for one service, and the other is the so-called parallel operation! Parallel operation is actually the work of the same operation, to the entire Cluster inside the CPU to perform a synchronous operation of a function. Because of the use of the operation of multiple CPUs ...
