Blade Server Purchase Analysis High performance data center

Blades are becoming more and more fashionable today, and many of the servers that require higher server performance are also considering whether to buy blades. As a server architecture for high-end business applications, this kind of server high price, has been in a very high-end position, ordinary users know little about it, if you want to buy, it may really is not the appropriate audience, the following author to share with you about Blade server related information.

What is a blade server? The blade is a Low-cost server platform for HAHD (high availability height density, highly available high-density) designed specifically for special application industries and high-density computer environments where each "blade" is actually a system motherboard, Similar to a separate server. In this mode, each motherboard runs its own system, serving a specified set of different user groups, with no association to each other. However, you can use system software to assemble these boards into a single server cluster. In cluster mode, all the motherboard can be connected to provide a high-speed network environment, you can share resources for the same user group services. There are two main types of blades in the current market: one for the telecom industry, the interface standard and the size specification PICMG (PCI Industrial Computer manufacturer ' s Group) 1.x or 2.x, and will be rolled out in line with PICMG 3. X's products, using the same standards of different manufacturers of blades and cabinets in theory can be mutually compatible; another type for the general calculation design, the interface may adopt the above standards or manufacturer standards, but the size specification is the manufacturer, pay attention to the performance price ratio, currently belong to this category of products mostly. Blades are currently best suited for cluster computing and IXP providing internet services.

What are the characteristics of a blade server? The biggest feature of the blade is the high density, for example, the IBM Blade chassis with 6U height, up to 14 blades, these blades can carry dual-core or quad-core processor, the performance of the entire blade server is greatly improved. HP, another international server manufacturer, has a higher density of blade chassis, and its Blp-class 30p series can install 16 blades in a 6U height chassis, and it is also a dual-path processor. In this way, high density, space-saving features should be the channel to purchase Blade server's first emphasis. In addition, the blade has the power to save energy, for example, IBM's blade server can save up to 40% of the electricity.

Which users need a blade server? Blade server space minimization and performance of the most characteristics also determines the scope of his use. For ordinary small and medium-sized enterprise users, two or three or several ordinary rack-type server or tower server can meet their requirements, the server occupied by the space is not too high requirements, then no longer need blade server. For the space and server performance is more sensitive to users, more in the telecom value-added areas, as well as the traditional needs of cluster computing customers, the former is mainly some network game operators or some large enterprises IDC data center, the latter is some oil, meteorology, manufacturing and scientific research units. At present, the high-speed development of the network game can be said to be a blade server needs to vigorously develop a major area, network game operators or telecom value-added operators are generally rented telecommunications or network operators such as the computer room, the rental of such rooms are based on the size of the server to be settled, and a unit of rent is quite expensive, So the largest possible reduction in the size of the server is the primary goal of this type of operator, and the blade is exactly the same feature. Prior to the Nineth city procurement of HP nearly 2000 blade server on the side to prove the above view.

Although there are many enterprises to the blade of high density and energy-saving features, but the current trends and facts have amply demonstrated the large number of enterprises on the blade server's huge demand. The following author recommended several blade servers to meet the needs of the enterprise User bulk procurement to form a large data center or other application services.
