Everyone of us know that when we want to search for any query we will type the same in the GOOGLE search engine and wait for the results….we get very frustrated even if the time taken to show us the result is more than 3-4 seconds….

But the server has to go through many number of algorithms to compute the result….it has to compute more than billions of calculations in a second, so the characteristics of the server effects our search result….

DELL has come up with a new server technology called BLADE SERVER….Let us know what this technology is about….

WHAT IS 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. Whereas a standard rack-mount server can function with (at least) a power cord and network cable, blade servers have many components removed to save space, minimize power consumption and other considerations, while still having all the functional components to be considered a computer. A blade enclosure, which can hold multiple blade servers, provides services such as power, cooling, networking, various interconnects and management. Together, blades and the blade enclosure form the blade system. (Different blade providers have differing principles regarding what to include in the blade itself, and in the blade system altogether.)

In a standard server-rack configuration, 1U (one rack unit, 19″ [48 cm] wide and 1.75″ [4.45 cm] tall) defines the minimum possible size of any equipment. The principal benefit and justification of blade computing relates to lifting this restriction so as to reduce size requirements. The most common computer rack form-factor is 42U high, which limits the number of discrete computer devices directly mountable in a rack to 42 components. Blades do not have this limitation; As of 2009, densities of up to 128 discrete servers per rack are achievable with blade systems.

Improved Design

Traditional rack servers bundle components into individual cabinets along with separate energy consuming devices like graphics cards and keyboards. Each server requires a power source and extensive cabling and patching. A single optimized blade system can replace an entire room of rack servers and operate from a solitary source of power. The innovative design improves the effectiveness of internal fans and cooling systems, reducing current draw by as much as 65 percent for a fully loaded blade chassis over similarly configured rack systems. Since a single cabinet houses an entire block of servers, the need for external cooling systems or “cold rooms” drops as well.

Virtualization

Server virtualization improves power consumption by reducing the hardware requirements of businesses and institutions. A blade server can comfortably maintain information and applications that were formerly housed in a dozen or more rack servers. Standard servers that run only one application often operate at or below 20 percent capacity. Blade systems maximize efficiency by ensuring that each server component is working to its full capability. By allowing systems and applications to network freely between servers, blade systems increase productivity and eliminate unused or underutilized CPU storage space. Data transfers easily between machines. Once configured, individual components can be removed, repaired and/or replaced while the system is fully operating, decreasing the need for shutdowns.

Increased IT Performance

While utilizing blade servers increases the energy efficiency of your computer operations, they also reduce the energy expended by your IT personnel. Blade systems are easy to install, easy to manage and easy to maintain. Switching to a virtualized blade server limits end user responsibility, employee calls to IT, and the resulting time consumed in solving simple operator errors. Since they successfully integrate interfaces among many servers, blade systems also reduce the time spent in updating or installing new software and in reconfiguring applications.

Once employed exclusively by large corporations, small and mid-sized businesses are embracing new technology to become more environmentally friendly while increasing productivity and cutting costs. Dell blade servers can take your business to a higher level and a bite out of your utility bill.
