Data???????????

Why do companies need data Center?

What is data Center ?

A data Center is a facility used to house computer systems and associated components, such as

telecommunications and storage systems. It generally includes redundant or backup power

supplies, redundant data communications connections, environmental controls (e.g., air conditioning, fire

suppression) and various security devices. Large data Centers are industrial scale operations using

as much electricity as a small town.

Connection??Is it simple!!!!!

How is India connected to the internet?

Surprise!!

– More than 24% of the internet’s traffic goes through TATA Cables.

– TATA Communications is one among the few Global tier-1 Internet service providers in the world.

Requirements for modern data Centers.

– The minimum requirements for telecommunications infrastructure of data Centers

– Computer rooms– Single tenant enterprise data Centers – Multi-tenant Internet hosting data Centers.

– The topology

Target

•Standardization/consolidation

•Virtualize

•Automating

• Securing

•

Carrier Neutrality– Today many data Centers are run by Internet service

providers solely for the purpose of hosting their own and third party servers.

– However traditionally data Centers were either built for the sole use of one large company, or as carrier hotels or Network-neutral data Centers.

– These facilities enable interconnection of carriers and act as regional fiber hubs serving local business in addition to hosting content servers.

Design considerations

– occupy one room of a building, one or more floors, or an entire building.

– form of servers mounted in 19 inch rack cabinets(aisles) – This allows people access to the front and rear of each cabinet. Servers

differ greatly in size from 1U servers to large freestanding storage silos which occupy many square feet of floor space.

– Some equipment such as mainframe computers and storage devices are often as big as the racks themselves, and are placed alongside them.

– Very large data Centers may use shipping containers packed with 1,000 or more servers each; when repairs or upgrades are needed, whole containers are replaced (rather than repairing individual servers).

– Local building codes may govern the minimum ceiling heights.

Design programming

– Facility topology design (space planning),

– Engineering infrastructure design (mechanical systems such as cooling and electrical systems including power)

– Technology infrastructure design (cable plant).

Mechanical engineering infrastructure designs

– Heating– Ventilation– Air conditioning – Humidification– Dehumidification equipment– Pressurization

– Electrical engineering infrastructure design– Technology infrastructure design– Site selection– Modularity and flexibility– Environmental control– Greenhouse gas emissions– Energy efficiency– Green data Centers – Network infrastructure
