Three major manufacturers of mainstream blade server sharp

The so-called http://www.aliyun.com/zixun/aggregation/13737.html "> Blade server" means that multiple-cassette 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 disks, similar to individual servers, in which each motherboard runs its own system, serving a specified group of users, with no association with each other.

Blade servers are designed with low power consumption, small space, the price of a single machine, and it also inherits some of the traditional server's technical indicators, such as hot Plug and redundancy applied to the blade server, these designs meet the needs of a dense computing environment for server performance, and some also through the built-in load balancing technology , the stability of the server and the core network performance are improved effectively. From the appearance, compared with the traditional rack/tower server, Blade Server can maximize the use of the server space and cost, and provide users with flexible, convenient means of extending the upgrade.

DELL PowerEdge1955 Blade Server

The Dell PowerEdge 1955 Blade Server enables extremely high rack density. A 7U-high chassis accommodates up to 10 blade servers that share power, heat, server management, and integrated I/O permeability devices. This reduces the physical footprint of the data center, reducing the number of cables by 70%, and installing and maintaining them more easily.

The Dell PowerEdge 1955 server is compact and delivers exceptional processing power efficiently. Each blade can be equipped with 2 dual-core Intel Xeon processors with High-performance next-generation processors. It also features fully buffered DIMM memory with higher performance to shorten latency and increase throughput. Integrated I/O connectivity options, including redundant Gigabit Ethernet layer 2nd switches and pass-through modules, Fibre Channel switches and straight-through modules, and InfiniBand (TM) pass-through modules. High availability is another important advantage of Dell's PowerEdge 1955 servers. All key support modules, including power, cooling, and management functions, are hot-swappable and redundant. Furthermore, each blade supports single device data correction (Device) memory technology that enables the system to tolerate multiple bit-bit errors.

For high-density data centers, simplifying management is of great importance. The PowerEdge 1955 server design takes into account the need to reduce deployment, management, and maintenance complexity. Each PowerEdge system is equipped with Dell OpenManage Itadministrator and Serverassistant software to guide you through installation and setup. The PowerEdge Blade server chassis also comes with the Dell remote Access card (DRAC)/MC Management module and integrated KVM for remote administration. Furthermore, the Dell PowerEdge 1955 Blade Server is available for existing Dell Modular server chassis to protect users ' technology investments and reduce total cost of ownership.
