Remodeling Data Center Servers
Large hardware buyers such as Google and Facebook are often buying systems for these products. These systems usually have more functions and are separated from enterprise servers. "

This means giving up some functions of embedded life cycle controller, such as providing standardized and lowest cost bare bone system. This does not mean that these are second-class rack systems because they usually install a lot of memory and the latest processors.
On the contrary, enterprise customers tend to run in a more complex environment, so there will be more types of servers, including rack and blade systems, and even some tower servers. Blade servers can be traced back to the early stages of adding more computing power to a given space. Typically, multiple server modules or "blades" are tightly squeezed into one enclosure to provide power, cooling, and connectivity to other facilities, and then each enclosure is installed in a rack in the data center.
However, according to Gartner's survey, blade server systems account for about the total expenditure of servers, with little or no standardized design. This means that the chassis produced by one manufacturer cannot be compatible with blade servers of other manufacturers, which will lead to the risk of locking customers.
At the same time, in the past few years, more and more enterprises have accepted another density optimization server, which combines the functions and features of blade servers and rack servers. These usually provide multiple server nodes or chassis chassis, which can flexibly mix and match different modules to meet customer requirements.
For example, Dell provides customers with a series of computing and storage modules, including two slot and one four slot server nodes. A node contains four independent modules in a single high-density configuration module.
However, rack optimized servers still account for the largest share of the server market, usually accounting for half of the total.
",, rack server system optimization, which still occupy a considerable market share, more traditional service providers, secondary and tertiary service providers are still purchasing a considerable number of framework optimization systems." said.

Infrastructure integration
Although the integrated infrastructure () system is a small part of the entire server market, its market share has increased. The electrical system uses the direct attached storage inside the node cluster to create a shared storage pool, and extends it by simply adding more nodes.
However, very large customers can use their mass purchase customization design capabilities. For example, Facebook's open computing project () provides a set of specifications that can design original design manufacturers（
