INTRODUCTION




Blade servers are stripped down computer servers with a
modular design optimized to minimize the use of
physical space.
Blade server saves space, minimize power consumption
and other considerations, while still having all the
functional components to be a computer.
The blade architecture allows a number of servers, on
the blade cards, to be housed with a single chassis.
The blade server combines the hardware of the
computer server, such as a processor, a memory and a
network connection, in one extension card, also known
as one server blade.




The blade server has a higher calculation capacity and
higher stability, and occupies less space than a
traditional computer server.
The blade server reduces the cost and the working
temperature; moreover many functions and performance
thereof are better than those of traditional computer
servers.
Network access for all server blades in a chassis
reduces cabling complexity and allows for relocation of
server resources.
A server blade, along with storage, networking and other
blades, are typically installed in a rack-mountable
enclosure that houses multiple blades that share
common resources such a cabling, power supplies and
cooling fans.
ORDINARY SERVER & BLADE SERVER…



Regular server or a personal computer or a
laptop includes at least a mother board, processor,
memory, hard drive, keyboard, display, network adapter,
video card, and power supply.
A blade server on the other hand has many components
removed for space, power, and other considerations
while still having all the functional components to be
considered a computer.
A blade server in the narrow definition is a thin, modular
electronic circuit board capable of performing
computational tasks.





A blade server in this sense is literally a server on a
board containing processors, memory, integrated
network controllers, an optional fiber channel host bus
adaptor (HBA), and other input/output (IO) ports.
Server blades typically come with 1 to 4 processors and
integrated Ethernet.
Blade servers typically have a front panel containing a
number of informational LEDs, relating to power and
system activity.
There may additionally be indicators of system failure,
which may be general or specific to blade components.
Together these components form a blade system, or
shortly often called a blade server.

SPECIFICATIONS
BLADE CHASSIS:






Blade chassis shall be 19" Width rack mountable and
provide appropriate rack mount kit.
Blade chassis shall support at least ten 1 height unit
(1U) hot swappable Blades.
Blade chassis shall be shipped with all cables and parts
required to attach all included peripherals to other blade
chassis as required for normal operation.
Blade chassis shall provide a device capable of reading
a 1.44 MB floppy.
Blade chassis shall provide a device capable of reading
a CD-ROM disc at a minimum 48x speed or provide an
alternate way of installing operating system and
application software.
The Blade Chassis power supply shall operate at a
nominal input voltage of 200VAC to 240VAC.
BLADE:



Each blade shall have a minimum of two
CPUs.
The blade shall be hot swappable.
They use pentium chipset
BLADE MEMORY:



Blade shall contain a minimum Random Access
Memory of 2GB and can be expanded to at least 8GB
without requiring replacing the initial memory.
Blade Random Access Memory (RAM) shall include an
error correcting feature.
The cache contains the data that is accessed most
often the CPU and memory. Cache memory accounts
for a small amount of high-speed RAM and is the
memory that the processor most often uses. The cache
runs almost as fast as the processor.
CONNECTIVITY:
The possible network connections are:

10Base-T Ethernet
10Base-2 Ethernet
Fast Ethernet
Token Ring
Fibre Channel

Fieldbus

FUTURE ENHANCEMENTS


Blade infrastructures are maturing to address the most
pressing issues that trouble CIOs, data center architects
and facilities managers with emerging technologies for
virtualization, converged I/O and networks, and systems
management for power and cooling.
According to the official, blade servers are the "growth
engine" of the server market, citing an International Data
Corporation (IDC) study which said the growth rate for
blades in the next five years is continuously rising,
posing 235 percent year-on-year growth in sales as of
the second quarter of this year. Also in mid-2007, HP's
blade server segment grew no less than 200 percent
year-on-year.
CONCLUSION




With the blade server, you can build vital solutions to
support your business that are more affordable, take less
time to maintain, use less power and are ready to grow
with you.
In an all-in-one design, you have the essentials to build
and maintain your infrastructure from start to finish.
You can host a choice from thousands of applications on
Windows, Linux, HP-UX and more.
We can connect to a variety of the most popular
networking brands and standards including Ethernet,
Fibre Channel.
