A famous term associated with Data Centers is tier standards. Tier standards can be defined as standardized channels used to figure out availability in a data centers. Tier system is very much important for all the data centers let it be Fully Managed Data Centers India or partially managed data centers. Tier system was developed by Uptime institute. It helps companies to calculate performance and ROI (return on investment).

There are 4 tiers in a tier system, with tier 4 being the best and tier 1 being in the bottom. Do decide which data center facility belongs to which tier Uptime Institute issue a certificate. This reduces the risk from companies which falsely claims for the certification for their facility. Till the start of the year 2008 more than 25 data center round the world had been certified by the Uptime Institute.

This certificate helps customers to figure out the standard of the data center facility in which their servers will be placed. In the fast jet age it is very important for a customer to check the standard of a facility, since e downtime of few seconds can cost million of bucks. Process of certification begins with engineers at Uptime Institute review submitted documents of the design.

Following the review Uptime employees visit the site and examine whether the site is newly built or just an expansion from a older facility. The inspection also includes various other service checks at the data center services india. In order to amplify the sustainability of the tier standards, Uptime Institute also added an grading system.

Tier 3 data center Tier System in Data Center

Below is a brief explanation of the four tiers of data center:-

Tier Level Requirements from data center
Tier 1 1) Non-redundant capacity IT equipments

2)Non-redundant and Dedicated distribution path for all the equipments.
Tier 2 1) Redundant IT equipments including all Tier 1 requirements
Tier 3 1) Distribution paths for the IT equipments are independent and normally one path serves equipment at a given time.

2) IT equipments should be completely compatible with the topology of the site architecture and also they should be dual powered.

3) other than these all the Tier 1 and 2 requirements
Tier 4 1) Cooling facility should include HVAC systems and chillers along with being dual powered.

2) All the distribution networks should be fault tolerant, let it be storage or electrical.

3) All Tier 1, 2 and 3 requirements.

A System which permit computer system to be separated from output/input devices like mouse, keyboard, display monitors, audio speakers is called a Remote Graphics Unit (RGU). Graphics sub-system of the computer is the main part being remoted. Typically there are three main causes behind using separate user interface of a computer from the actual computer are:

  • Decrease noise and heat from the rooms where many computer operators are working.
  • Smooth the progress of  computer maintenance by placing all computers in very close closeness to each other.
  • Locking computers away from users for government or commercial security.

RGU or Remote Graphic Unit originated with researches on graphics controller on mainframe computers in the 70s era. Earlier Remote graphic units are associated with high end workstations running Unix-like operating systems and later with Windows. Normally RGUs are used for some unique applications like Computer Aided Drafting, Financial Services Commodity Trading Desks, Remote Sensing e.t.c. Dedicated X terminals are also included, depending on the choice of the user how he wants to use RGU. A Remote Graphics Unit effectively split computers PCI-Express bus or PCI and then transmit only bus command over to the user side. RGUs process of working is different from that of DVI Extension and KVM Extension. Traditional graphics unit or GPU perform processing in DVI and KVM Extensions. Bus data however is way too small then rendered graphics data, theory behind the working of RGU is like it is possible to achieve better graphics and resolutions performance if only the distance of separation is large between the computer side and user side input/output devices.
