INTRODUCTION What is the difference between a server and a blade server? A blade server is a stripped down server computer with a modular design optimized to minimize the use of physical space and energy. Price: entry-level server blade for some $700,. Entry-level chassis start at around $2,500, When you add the cost of support, setup, infrastructure, cooling, maintenance, and other, you can easily get to $20,000 for an entry-level blade server just to start. 7.9% 92.1% 21.6% 78.4% Blade Servers Other Servers

ENCLOSURE/CHASSIS Chassis refers to any backplane module that has empty slots where the front end modules (like blade servers) & add-on modules can be inserted. oThe major components of the Blade Server Chassis are listed below : Server modules (Blades) with Multi-Core Processors, RAM, hard disks, etc. These blades are inserted in to the empty front end slots of the Chassis. Common Power Supply Modules. Common Fan/Cooling Modules. Midspan connections (usually specialized cables) that connect specific add-on/integrated Chassis modules and Blade modules. Common Input/Output expansion modules (Eg. PCI Express modules). Specialized expansion modules (Like RAID expansion modules, etc). Storage Module(s). Networking Module(s) (Switch ports, Ethernet cables, etc).

HARDWARE CONFIGERATION OF BLADE SERVERS Chassis (exterior): The components of blade servers are placed in a chassis. The chassis can hold a number of server blades. This blades can be switched and we can use it by user’s convenience. Intel corporation had made a blade server chassis which can hold up to 30 servers. Components in chassis : Server blade Switch blade Management blade: The management blade is to manage the blades in the chassis.The management of blades is the main issue of using blade servers.

HARDWARE CONFIGERATION OF BLADE SERVERS CPU: Central processing unit NIC: Network interface card Middle plane: Middle plane is for connecting the switch blades.Swich blades are the switches in which server blades are connected. NIC Hard disk Memory CPU

Figure will explain the hardware configuration of blade servers.

ISSUES Business systems that use blade servers have a large number of server blades, and when a large number are in use, it is important to ensure they do not degrade system reliability. Although many factors can degrade a system’s reliability, the most important ones to consider are : 1) Hardware faults. 2) Software faults. 3) Insufficient resources to deal with unexpected load increases. 4) Human error.

Features 1. To reduce power consumption. 2. Simplified deployment and maintenance. 3. To maximize the use of data center space 4. Lower hardware costs

APPLICATION Blade servers can be found in many applications, such as Web page serving and caching SSL encrypting of Web communication Infrastructure applications such as DNS or Active Directory Streaming audio and video content File sharing and serving Terminal services messaging Databases hosting (Ms SQL, Oracle) ERP hosting (for example SAP) Virtualization (VMWare, Microsoft Virtual Server, etc.)

Disadvantages Expensive configuration Expensive tool, i.e. economies of scale Vendor-lock Business case Heating and cooling

BENEFITS OF BLADE SERVER Condensed, high-density Load balancing and failover Power consumption & power management Lower management cost Network and other cabling Flexibility, modularity, and ease of upgrading Deployment and scalability Disaster management

FUTURE DEVELOPMENTS In the future, systems themselves will perform analysis, make decisions autonomously based on business requirements, and reconstruct systems organically. The key technologies for achieving these functions are considered to be system composition and autonomic control.

BLADE SERVER TECHNOLOGY OVERVIEW

CONCLUSION Blade servers can greatly improve the reliability of business systems. Provisioning realizes swift action and efficient resource utilization when faults and load increases occur. In order to realize provisioning, resource management for configuration management, pool management, and automation is indispensable. System walker Resource Coordinator offers provisioning solutions on blade servers. In the future, provisioning solutions will have extended support ranges and these new solutions will form the basis of autonomic provisioning.
