Datacenter is a building with extremely good infrastructure to operate server systems, data storage and connect globally with other datacenter. Datacenter can serve the business needs of one or more technology businesses so it requires high availability and 24/7 continuous operation. Therefore, the data center infrastructure must integrate all leading technologies in terms of source and cooling solutions for servers.
The structure of the basic of Datacenter
DataCenter infrastructure will include elements such as a power supply system, cooling system, fire protection system, security monitoring system, network connection system, transmission, monitoring center. NOC operation and DR incident rescue center.
Requirements of a Data Center
Based on the international standards TIA-942 (TIA: Telecommunications Industry Association) on building a Data Center, the following requirements must be met:
– Provide mains power to the data center, to ensure continuous operation without power problems and must have backup power for data centers such as UPS and generators backup power.
– The air conditioning system must use the correct type of air conditioning because the data center environment requires very high-temperature stability to meet the coolness for equipment operating inside the Data Center. Whether.
– Data centers must be provided with fire-fighting systems using clean air for servers, networks and central control rooms. Walls and doors have high heat resistance for long periods.
– The raised floor system (optional), the floor is designed flat so that the upper device is not inclined and withstand the load for IT equipment placed on top. The floor is also used to cover the power cable, the network cable goes below to create the data center aesthetic.
– Security systems (Access control and Camera system) for data centers will use card readers or biometrics to enhance security. CCTV system can use IP camera or Analog camera to observe all activities inside Data Center.
– Data center will be provided with a lighting system in accordance with standards of a Data Center, providing adequate lighting in case of emergency. Improve work efficiency for operators.
– Monitoring environment to monitor regularly the operation of the Data Center can prevent incidents from the smallest to avoid affecting the entire Data Center system.
In addition, the data center must satisfy: expansion & development; energy saving; adapt many equipment of manufacturers; The system is always checked before deploying to ensure minimizing the time the system is down, always being monitored and alerted before the problem occurs.
Benefits of building Data Center infrastructure
Benefits that a complete Data Center brings to customers are:
– Has a centralized data system
– Meet the explosion of data
– Strict security control
– Minimize damages due to incidents due to power outages …
– Always have redundancy and high responsiveness
– Can be easily developed and upgraded
– Be alerted when any incident occurs
– Balance the development of the company and IT investment
– Reduce costs incurred.
Data Center international standards to meet what
The data center has four different levels and is evaluated based on service responsiveness, operation, and risk provisioning.
Uptime Institute, an American organization, has set the evaluation standards for the design, construction, operation, management and service stability of Data Center. The “Tier” standard offered by this unit is universally accepted and is rated as a leading certificate for data centers.
Specifically, the evaluation of Uptime Institute is divided into four levels, from low to high, including: Tier I, Tier II, Tier III, Tier IV. In particular, Tier I has a continuous uptime of 99.67% and has no integrated redundancy, can be interrupted (downtime) 28.8 hours per year, usually applied to small businesses, personal pages. Tier II has an uptime of 99,749%, a downtime of 22 hours per year and has a backup of power and cooling.
Tier III is the highest level Data Center in Vietnam can achieve, which requires up to 99.982% uptime, downtime of no more than 1.6 hours per year, N + 1 backup operations. Specifically, the Tier III data center must have a diesel generator with a fuel that runs for at least 12 hours, a backup with two oil tanks, and each tank has a fuel that can run for 12 hours. In addition, it must have an automatic transfer system (ATS) to automatically switch to standby if the main power fails.
The highest is Tier IV, but in Vietnam, no Data Center has received a certificate from the Uptime Institute and no data center has received it. In fact, Tier IV is equivalent to the Data Center used by the US Government. It has uptime 99,995% and a maximum downtime of 0.8 hours per year. Of course.
