In fact, according to Moore’s Law (named after the co-founder of Intel, Gordon Moore), computing power doubles every few years. Data Centres 104 105 Tier Requirement Tier 1 Tier 2 Tier 3 Tier 4 Power Supply to Data Centre 1 1 2 (One Primary, One Backup) 2 (Both Primary) M&E Systems Supporting IT Equipment (e.g. Not All Data Centers Have to be Tier-4 Choosing an optimal criticality is a balance between a business’s cost of downtime and a data center’s total cost of ownership Choices may be limited depending on whether a new data center is being built, or changes are being made to an existing one Existing data center projects (i.e. It is also the most expensive one. Data Center Multi-Tier Model Design This chapter provides details about the multi-tier design that Cisco recommends for data centers. It is fully redundant with multiple cooling systems, sources of power and generators to back it up. The data center has been verified as standing up to real-world challenges and reaching the requirements of the organization. A Tier 3 data center combines and exceeds features and capabilities of Tier 1 and Tier 2 data centers but with redundant capacity and data center infrastructure components. These standards classify Data Centers into 4 Tiers based on critical systems that determine uptime—1 being the lowest, 4 the highest. . With a fully redundant infrastructure, a Tier 4 data center meets and exceeds all of the requirements of the aforementioned three tiers. Data center owners turn to Uptime Institute during both of these phases, for an unbiased review of their work, to ensure that data center designers, contractors and service providers are delivering against their requirements and expectations. )There)is)sufficientMEP)capacity)to) meetthe)needs)of)the)dataprocessing)systems)even)when)one)of)these)redundantMEP) … The multi-tier design model supports many web service architectures, including those based on Microsoft .NET and Java 2 Enterprise Edition. Certifying Data Centers Datacenters are certified as Tier 3 or Rated 4 by certifying bodies like TIA and Uptime. Data centers range from Tier I to Tier IV, with each tier incorporating the lower tier’s requirements. Each tier is progressive, with Tier I being the simplest and Tier IV being the most resilient. At minimum, Tier 4 data center uptime must guarantee 99.995% availability. . Dazu hat das US-amerikanische Uptime Institute in der TIA-942 (Telecommunications Infrastructure Standard for Data Centers) eine vierstufige „Tier“-Klassifizierung vorgenommen, wobei der englische Ausdruck Tier für Rang oder Schicht steht.. Verfügbarkeitsanspruch und Redundanz sind die Unterscheidungskriterien für die Tier-Kategorien 1 bis 4. The Data Centre should have an AMF Panel connecting the DG, UPS such that automatic switchover takes place during power failure. Adequate units of cameras should be installed to cover all areas SDS Requirements . This is a model for a data center with a 5 kW per cabinet design density (approximately 160 W/ft2 or 1,722 W/m2). . Not all data centers are created equal. . The modern data center is an exciting place, and it looks nothing like the data center of only 10 years past. Tier 5 Sets New Standard for Excellence in the Data Center Industry. Green certifications, such as LEED, Green Globes, and Energy Star are also considered optional. . . Industry Standards and Legal Requirements 3 Optimum Physical Security: Layering is the Key 4 Why Inner Layers are Important 4 First Layer: Perimeter Security 5 Overcoming Perimeter Restrictions 5 Second Layer: Facility Controls 5 Third Layer: Computer Room Controls 6 Fourth Layer: Cabinet Controls 7 The Secure Data Center 7. Schneider Electric – Data Center Science Center White Paper 122 Rev 2 4 Institute’s Tier Data Center Site Infrastructure Tier Standard, TIA 942, and Syska Hennessy Group’s Criticality Levels™. An ideal target value for an existing data center is 1.5 or less (new centers should aim for 1.4 or less, according to Federal CIO targets and benchmarks. A Tier I data center represents an availability of 99.67% and has no built in redundancy. Guidance. . Tier 4 data center adheres to all the requirement of Tiers 1, 2 & 3 as well as ensuring that all equipment is fully fault-resistant. Bell Data centers seldom meet the operational and capacity requirements of their initial designs. The rack arrangement on the data center raised floor can also have a significant impact on cooling-related energy costs and capacity, as summarized in the next section. 4 UPTIME INSTITUTE WHITE PAPER Tier Classifications Define Site Infrastructure Performance Tier Performance Standards Tier I: Basic Site Infrastructure The fundamental requirement(s): • A Tier I basic data center has non-redundant capacity components and a single, non-redundant distribution path serving the computer equipment. . You need to know what to look for. 1.4 Surveillance 1.4.1 Video Surveillance Video Surveillance or CCTV System has to be provided mainly for security purposes. . Calculating Space and Power Density Requirements for Data Centers ... lower cost Tier 2 design data center, and the upper curve is a Tier 4 design. . A Tier 4 data center has all the infrastructure of Tiers 1, 2 and 3, with additional components that qualify it as Tier 4. As it stands now, there are four tiers, and as you would expect, they are defined precisely. ANU ITS DATA CENTRE OPERATIONS 4 | A NU D A T A C E N T R E S T A N D A R D S M a r c h 2 0 1 4 1 Executive Summary This document outlines the standards that are enforced within the data centres at the Australian National variables involved, successful data center design and construction begins with professional engineering. .

Data Center Tier IV requirement is design to accomplish 99.995% available operations. . Show stakeholders and clients that your data center meets rigorous standards and can support the needs of the company, as determined by an unbiased third party. A PUE of 2.0 or higher indicates a need for review. . Each level is progressive, incorporating the requirements of all the tiers below that. Not only do these data centers, preferred by enterprise corporations, provide 99.995% uptime per year (less than 0.5 hours of downtime per year), they also are complete with at least 96-hour power outage protection. o An example of a non-emergency stationary application would be producing power for normal operations of a facility or supplying power to an electric grid for utility peak shaving. This option might be sufficient for a small business, website, or blog hosting but certainly not for an enterprise with mission critical applications. .
