The Beginning of the Computer Era - A Dedicated Room
While the data center as we know it was perfected during the dot com boom of the late 1990s, data centers actually have their roots in the earliest beginnings of the computer era. Early computer systems, which were huge, room-sized machines, required a lot of space and a controlled environment. The complexity of operating and maintaining these machines also led to the practice of secluding them in dedicated rooms.
While the data center as we know it was perfected during the dot com boom of the late 1990s, data centers actually have their roots in the earliest beginnings of the computer era. Early computer systems, which were huge, room-sized machines, required a lot of space and a controlled environment. The complexity of operating and maintaining these machines also led to the practice of secluding them in dedicated rooms.
Computer security became a consideration during this era. These early computers were incredibly expensive, and many of them were used for military purposes or important civilian business ventures. A dedicated room allowed businesses and organizations to control access to the machine.
Another factor influencing the trend toward separate computer rooms was the need to keep systems cool. Early computer systems used a great deal of power and were prone to overheating. Dedicated rooms could be climate controlled to compensate for the tendency to overheat.
These early computers required a multitude of component-connecting cables, and these cables needed to be organized. This led to the creation of some of the data center standards we know today. Racks were devised to mount equipment, and cable trays were created. Also, floors were elevated to accommodate these early computers.
The Advent of
Microcomputers
During the 1980s, the computer industry experienced the boom of the microcomputer era. In the excitement accompanying this boom, computers were installed everywhere, and little thought was given to the specific environmental and operating requirements of the machines.
Organization of information was difficult to achieve, and lost data became a major concern. Information technology teams were developed to maintain and install these early microcomputers, but clearly, the industry needed a solution.
The "Data
Center" is created
Soon
the complexity of information technology systems demanded a more controlled
environment for IT systems. In the 1990s, client-server networking became an
established standard. The servers for these systems began to find a home in the
old dedicated computer rooms left from the early computers.
In
addition to putting servers in a dedicated room, this time period saw the
invention of the hierarchical design. This design came about through the easy
accessibility of inexpensive networking equipment and industry standards for
network cabling.
The
term "data center" first gained popularity during this era. Data centers
referenced rooms which were specially designed to house computers and were
dedicated to that purpose.
The Internet Data Centre
As
the dot com bubble grew, companies began to understand the importance of having
an Internet presence. Establishing this presence required that companies have
fast and reliable Internet connectivity. They also had to have the capability
to operate 24 hours a day in order to deploy new systems
Soon,
these new requirements resulted in the construction of extremely large data
facilities. These facilities, called "Internet data centers" were
responsible for the operation of computer systems within a company and the
deployment of new systems. These large data centers revolutionized technologies
and operating practices within the industry.
However,
not all companies could afford to operate a huge Internet data center. The
physical space, equipment requirements, and highly-trained staff made these
large data centers extremely expensive and sometimes impractical.
Now - Private Data Centers,
Improved Standards
Private
data centers were born out of this need for an affordable Internet data center
solution. Today's private data centers allow small businesses to have access to
the benefits of the large Internet data centers without the expense of upkeep
and the sacrifice of valuable physical space.
These
days, operating and constructing data centers is a widely-recognized industry.
New standards for documentation and system requirements add a high level of
consistency to data center design. Disaster recovery plans and operational
availability metrics ensure the reliability of today's data center systems.
What the Future Holds
The
future of data center design is likely to reflect today's emphasis on
green practices. Environmentally responsible computer and networking systems,
as well as refined operation practice, are likely to shape the data centers of
the future.
