Server

• Any device or computer program that enables other
  devices or programs to have functionality is
  referred to as a server. A server refers to any
  computerized process which is used or called upon
  by a client in order to share resources and
  distribute work. Servers can be application
  servers, database servers, computing servers, web
  servers etc.
• Web servers are those servers that are provided
  by web hosting companies for storing the files of
  websites in order to make websites accessible.
  These web hosting companies provide the necessary
  services and technologies that make websites
  accessible over the Internet and are often termed
  as the Best Website Hosting Company, the Best
  Windows Hosting Company or the Top Cloud
  Hosting Company when their services are
  exceptional.

Types of
Servers (based on their structure)

• YELLOW
• There are essentially three types of servers
  based on their structure. These are rack servers,
  blade servers and tower servers. The focus of
  this PPT will be on blade servers and rack
  servers. The major difference between these two
  is that a rack server refers to an independent
  server that is installed in a case whereas blade
  servers work with one another in one server
  chassis.

Rack Servers

• A rack server is a rack-mounted server. It can
  fit into a server rack. It is efficiently
  configured to support a wide variety of
  requirements. It is wider and flatter and can fit
  into any server rack. A rack server is very
  beneficial when a small number of servers are
  required as it incurs low upfront cost. Hence, it
  is highly economical. Moreover, a rack server
  aids in reducing space consumption. This is
  because this type of a server can be mounted
  inside a rack and is designed in a way where it
  can be positioned in a bay which is accomplished
  by stacking servers vertically one over the other
  along with other devices that include SAN
  devices, batteries, storage units, cooling
  systems, network peripherals etc. With regard to
  processors, RAM and storage, rack servers are
  expandable but one would need to make the
  necessary arrangements when it comes to space in
  a rack for accommodating such upgrades.

Features of Rack
Servers

• YELLOW
• Deliver powerful performance for running high-end
  applications.
• Consume less space and fit conveniently.
• Equipped with internal fans that make cooling
  easier.
• Highly efficient when more than one server is
  required as these do not need a huge chassis.

Benefits of Rack Servers
There are many benefits of rack servers which
shall be discussed in this slide and in the next
three slides. The first of these benefits is
mentioned in this slide. Self-standing Every rack
server is equipped with the necessary hardware,
which enables it to perform all the tasks that a
server is supposed to perform. This versatile
server is a stand-alone server that can be used
for running high-end applications.

Increased Security

• YELLOW
• Enclosed rack servers that have locking
  mechanisms aid in not only organizing IT related
  hardware in a single location but also prove to
  be an important choice for organizations that are
  concerned about security. A locked rack ensures
  that ones IT equipments physical accessibility
  remains under ones control.

10

Better Access and
Organization

• YELLOW
• When ones servers are located in one place and
  are accessible easily, it saves time. Since all
  the hardware is organized, maintenance and
  troubleshooting become easier and more efficient.
  All the devices are housed together in a rack,
  which makes cable management more organized.

11

Failure Containment and
Economical

• YELLOW
• Failure Containment
• Rack servers require very less amount of effort
  with regard to identifying, removing and/or
  replacing a malfunctioning server with another.
• Economical
• A rack server delivers computing power along with
  efficiency at the most cost-effective price.

12

Disadvantages of Rack Servers

• YELLOW
• The main disadvantages of rack servers are
  mentioned below, in no particular order.
• Difficult to Maintain- In this type of an
  arrangement, multiple devices are stacked in
  racks, which makes it harder to maintain these
  when the number of racks increase significantly.
• More Power Usage- The high component density of
  rack servers requires additional cooling systems
  which results in more power consumption.

13


Blade Servers

• YELLOW
• A blade server is not only the latest but also
  the most advanced type of server that is
  available. It can be referred to as a hybrid rack
  server. In this type of an arrangement servers
  exist inside a blade enclosure and form a blade
  system. Blade servers are the smallest servers
  that are available at present. Hence, these aid
  significantly in conserving space. Very few
  internal components are required by blade
  servers. This is because multiple blade servers
  can be slid and fitted on a large blade chassis
  for efficient operation. These servers are
  usually used for higher computing requirements
  and provide the type of architecture that aids in
  scaling a higher processor density.

14

Features
of Blade Servers

• YELLOW
• Reduced total power consumption. This is due to
  the fact that the massive chassis of blade
  servers enable these to supply power to multiple
  servers.
• Minimal requirement of space. Blade servers not
  only require minimal space but also provide high
  processing power.
• Promotes hot-swappable features. This makes it
  easier to replace a blade that is encountering
  problem.
• Reduced usage of individual cables for each blade
  chassis server. This happens because blade
  servers need a single cable.

15

Benefits of
Blade Servers

• YELLOW
• There are numerous benefits of blade servers,
  which are mentioned below.
• Simpler Load Balancing- Since blade servers have
  a simple infrastructure, load balancing among the
  servers becomes much easier.
• Minimal Requirement of Space- Blade servers are
  the smallest and the most compact servers which
  ensures that these require the least amount of
  physical space.
• Centralized Management- All the blades in a blade
  server can be connected through a single
  interface. This renders the task of maintenance
  and monitoring easy.
• Reduction in Cabling- The usage of cables is next
  to negligible in it in comparison with rack
  servers.

16

Disadvantage of
Blade Servers

• YELLOW
• Expensive- Its initial configuration is
  expensive. Despite it being easy to upgrade a
  blade server, the initial costs related to
  capital, configuration and its deployment can be
  quite high.
• HVAC Energy Costs- Blade servers are not only
  very powerful but have high component density.
  Hence, adequate measures need to be taken to
  ensure that these dont get overheated. HVAC
  (heating, ventilation, and air conditioning)
  systems need to be managed efficiently for blade
  servers and often incur additional expenses.
