How are data centers managed?

Operating a data center with maximum efficiency and reliability requires the shared use of facilities and IT.

IT systems:

servers, storage devices and the network must be properly maintained and updated. This includes, for example, operating systems, security patches, applications, and system resources (memory, memory, and processor).

Facility infrastructure:

All support systems in a data center are exposed to heavy loads and must be properly maintained to ensure satisfactory operation. These systems include cooling, humidification, air treatment, power distribution, emergency power generation and more.

Monitoring:

When a device, connection, or application fails, business-critical operations may be interrupted. Sometimes a system failure applies to other applications based on failed drive data or services. For example, many systems such as inventory control, credit card processing, accounting, and more are integrated into a complex process, such as e-commerce purchasing processing. One mistake will endanger everyone else. In addition, modern applications generally have a high degree of interdependence between devices and connections. To ensure maximum availability, key applications, systems, and connections involved in a company’s various workflows must be constantly monitored.

Building management system:

For larger data centers, the building management system (BMS) allows constant and centralized monitoring of the system, including temperature, humidity, electricity and cooling.

The management of IT systems and data centers is often outsourced to third-party companies that specialize in monitoring, maintaining and renovating systems and facilities based on shared services.

What is a green data center?

A green data center can operate with maximum energy efficiency and minimal environmental impact. This includes mechanical, lighting, electrical and IT devices (server, storage, network, etc.). Within companies, the focus on green data centers is primarily driven by a desire to reduce the enormous costs of electricity associated with running a data center. This means that greening is a way to significantly reduce operating costs for IT infrastructure.

The federal government is also stimulating interest in green data centers. In 2006, Congress passed Public Law 109-431 and called on the EPA to “analyze the rapid growth and energy use of data centers by the federal government and private companies.”

In response, the EPA produced a comprehensive report that analyzed current trends in energy consumption and energy costs for data centers and servers in the United States and identified existing and emerging opportunities to improve energy efficiency. It also made recommendations for pursuing these energy efficiency opportunities at the national level through the use of information and incentive programs.

According to the EPA report, the two largest energy consumers in the data center are:

• Support infrastructure – 50% of the total

• General servers – 34% of the total

Since then, important steps have been taken to improve server efficiency. Blade servers and high-density storage now offer much more computing power per watt of power. Server virtualization allows companies to reduce the total number of servers they support. With the introduction of EnergyStar servers, numerous options have been offered for both the public and private sectors to reduce energy consumption by 34% for general servers.

The biggest opportunity for additional savings is, of course, in the data center support infrastructure. According to the EPA, most data centers consume 100% to 300% more energy for support systems than is used for core IT operations. A combination of best practices and migration to improved fast-reimbursement (such as ultrasonic humidification and airflow adjustment) can reduce this overrun to about 30% of IT load.
