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.

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.
o The 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.

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
Email 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.
