Tier design

All IT Rooms can design and check your design for the Tier standards of Uptime Institute. This can result in a certification of the datacenter by Uptime Institute. For datacenters this is an important issue. With this approval a datacenter can convince potential customers on the reliability and uptime of the datacenter by given the Tier class that has been certified.

Checking the relevant design document scan only be done by an approved Accredited Tier Designer. After the approval of the Accredited Tier Designer, Uptime Institute can give the datacenter the certificate according the Tier class that has been checked. Our Senoir Consultant Mr. Pieter Carlier has successfully passed the Uptime Institute training in Singapore. He will be happy to help you with the certification of your datacenter.

Tier classification

The Uptime Institute provides education, publications, consulting, certifications, conferences and seminars, independent research, and thought leadership for the enterprise data center industry and for data center professionals. The Institute has pioneered and continues to develop numerous innovations that subsequently have become industry standards, including hot/cold aisles, site infrastructure energy overhead metrics and measurements, cost modeling, the dual-power specification, and the Tier Classification system for rating the concurrent maintainability and fault tolerance of data center facilities.

All IT Rooms uses the Tier classification for rating server rooms/datacenters. The desired Tier classification is the starting point for the design and determines the availability and reliability of your server room/datacenter.

The Tier norm at a glance:

  • Tier I is a basic datacenter featuring a single path for distributing power and cooling, without the use of any redundant components. These datacenters have a high risk of unplanned down time.

Tier design

  • Tier II is a datacenter with redundant components, but still has a single path for power and cooling. An Uninterruptible Power Supply (UPS) and an Emergency Power Generator make this type of datacenter less sensitive to unplanned down time.
  • Tier III datacenters feature two paths for power and cooling, where the first path is always active and the second path standby.  Unplanned activities and outages still may lead to unplanned down time.
  • TierIV datacenters have multiple redundant paths for the distribution of power and cooling resulting in a high availability rating (99,995%).

Furthermore Tier V and Tier VI are defined. These datacenters offer an even higher availability rating where two identical datacenters are used for redundancy purposes with a safe geographical distance in between them.
