Analysis of Blade server creating desktop Cloud computing Architecture

In the Desktop cloud computing solution, the server plays an important role, carrying all the user data, applications, and computing tasks, in other words, the server is related to the performance of the entire Desktop cloud computing architecture. So, in the server selection, which kind of server is more suitable for desktop cloud computing infrastructure construction? Blade server is an ideal solution, its high-density, centralized management, easy to expand, easy to manage features such as desktop cloud computing applications are very compatible with the implementation of more efficient virtualization, hosting desktop cloud computing applications.





Higher computing density: blade is a more centralized server type, each blade is only 1U rack server 1/2 or even 3/1 size, but the processor, chipset, memory, I/O control chip, hard disk and other major components readily available, storage, switch module, Management module, Components such as cooling fans are concentrated in a standard height rack chassis and are shared by all blade modules. For example, IBM BladeCenter E chassis can accommodate 14 blades in 7U space to achieve optimal deployment density, helping enterprises to greatly save room space.





more convenient management: Crammed with tower, rack servers in the data center of the complex cable is also the nightmare of IT administrators, connectivity failures are common, failure to troubleshoot after it is also very difficult. The blades are more centralized, and the chassis integrates power supplies, fans, switches, KVM, and other modules, greatly reducing the number of cables, fewer connecting cables reduces the likelihood of connectivity failures, and makes the data center cleaner. In the manageability, Blade server has a more complete fault diagnosis function, can be centralized management, this is the rack can not match.





lower cost: The price of a single blade is often higher than that of a configured rack server, and a huge blade chassis is also difficult to give a low cost impression. Indeed, if the enterprise only uses a small number of blades, then the cost relative to the rack is higher. But because the blade server shares power supply, heat dissipation, exchange, Management module, as the number of blades increases, the cost of a single blade also decreases. According to IBM estimates, when the number of more than 6 units, Blade server price advantage can be reflected. Cost savings in a large-scale deployment environment are even more pronounced, considering that blades can save space and human costs.





In addition, in addition to the common features of these blades, some products have the unique characteristics of the blade can be more consistent with the needs of desktop cloud computing. The IBM EX5 Architecture Blade Server, released last year, introduces innovative MAX5 memory expansion technology that allows blades to multiply memory without adding processors, such as the IBM HX5 Blades with 16 DIMMs, which can be expanded to 40 DIMMs via a connection MAX5 module, Maximum support for 640GB of memory, can support more virtual machines, and reduce the cost of software license by CPU charging.





IBM HX5 Blade also introduced Flexnode smart zoning technology, two HX5 blades can be combined into a four-way blade, more flexible configuration, while increasing system availability, once a node failure, another node can host all applications, to ensure that the system will not completely downtime, This is of great importance for desktop cloud computing applications that require high availability. In addition, IBM system Director management software can help users achieve unified IT infrastructure management, not only to support the server, storage and other hardware, but also to support Linux, Windows, VMware and other mainstream operating systems, Enables users to implement physical and virtual system management in a Web interface that greatly reduces management difficulty.
