Data centers

Measuring over longer periods

Rittal has updated its monitoring and remote management system for data centers. The company’s entire sensor portfolio is now based on CAN. Measuring and checking data over longer periods of time has become easier.

MONITORING AND REMOTE MANAGEMENT CAN DELIVER maintenance and operating cost savings, and increase up-time for data centers. Rittal’s Computer Multi Control III (CMC III) solution and its monitoring, measurement, and control capabilities minimize outages and enable the user to take preventive action. High availability is critical to in-house data centers: according to a recent study carried out for the company’s by market intelligence researchers IDC, 93 % of IT managers believe their internal data center is key to long-term competitiveness.

Rittal has added further functionalities to CMC III – for greater control and reliability. It is now easier to measure and check data and consumption figures over a longer period. In addition, the German company has converted its entire sensor portfolio to CMC III technology based on CAN, simplifying the task of managing and monitoring key data-center parameters. Processing units are integral to the solution. The Compact Processing Unit has up to four additional CAN monitoring components. The higher-performance processing unit enables users to connect up to 32 additional monitoring components.

The firmware enables users to observe and record measurements obtained over longer periods. Data can be stored on SD cards and USB sticks with a capacity of up to 32 GiB. In addition, the user interface allows the operator to enter measurement intervals ranging from five seconds to 24 hours. Trend data for periods of up to 48 hours can be displayed on the unit itself, while observations recorded over longer periods can be exported to analytics software.

All sensors from the previous CMC II system have been converted to the CMC III connector format. The sensors – which include smoke detectors and a 15-meter-long leakage sensor that can trace the precise location of a leak – can now be connected directly to the unit without an adapter. In addition, the unit can be used to monitor the DET-AC III extinguisher system via CAN.

Intelligent door control systems

The company has also expanded its range of automatic door opening systems. During normal operation, electromagnets keep the door closed. However, in an emergency – such as if the enclosure’s cooling mechanism fails – a gas-pressurized spring pushes the door open in a controlled manner. The CMC III unit performs the task itself. A solution is also available for enclosed cooling systems with liquid cooling packages (LCP). If an alarm is triggered, the LCP can switch to full load, and the extreme negative pressure keeps the door closed despite the gas-pressurized spring. The high-performance fans found in modern servers can also keep doors closed in an emergency. CMC III, in conjunction with Rittal’s door kit extension comprising two additional motors (one for each door), offers a solution: The motor pushes the door open mechanically using a bar – overcoming the powerful force of the negative pressure.

Data centers at too low temperatures

“Business growth through IT”, a white paper published by the international market intelligence specialists IDC, describes how data centers contribute to the success of mid-sized enterprises. The results show that internal data center resources are key to long-term competitiveness. According to the study, IT professionals are typically operating data centers at far too low a temperature, hampering energy efficiency. Instead of cooling entire rooms, it is more efficient to work with direct cooling within the rack or in the individual aisles. As a result, a higher overall temperature is allowed in the room, reducing the costs of cooling.

The analysts conclude that modular data centers offer a viable solution to upgrading IT infrastructure. The findings are based on a survey of 500 IT decision makers in Germany, the United Kingdom, Italy, the Netherlands, and Sweden.
