Micro data centers are centralized- and have a display watching the power status, sub-system and temperatures and humidity status. It supports 365 days 7×24-hour unattended, minimizes IT operation, remote monitoring, and maintenance cost. It’s a closed micro-environment which is dust-proof and noise canceling, which reduces the IT equipment failure value and life cycle. It also has an emergency ventilation system and will be open when the AC is failing. It also comes with an automatic fire extinguishing system.
Plant operations are using Ethernet at all levels of manufacturing from 1/0 blocks and sensors, controllers, switches, and storage. It’s important to ensure that linkage between devices and systems is secure, protected from natural things like- heat or dirt, and optimized to speed the diagnostics. This factor leads to the systems ability to isolate networks when security threats produce risk.
Micro data centers, a multiple single, or partial cabinet/rack that secure storage, switches, servers, power supply DIN- rail device and backup systems.
The MDC provides the bridge between the industrial or corporate networks to provide these functions:
* Provide installation
* Maintain network uptime
* Manage network security
* Speed changes and troubleshooting
* Provide the ability to segregate network
An MDC is also a new concept, which brings the next phase in the transition from tower computers systems in an environment to rack and cabinet-based deployments. It also has the ability to serve a variety of enterprises. The MDC must run it applications with:
* Control network, recipe download, outer loop control
* Quality control, maintenance, asset management, material handling
* ERP Integration
* Process historian, event monitoring, production tracking and DEE reporting
In addition, the MDC can form a network hub that has servers, existing to the cabling and switches together. For large facilities or remote locations, it can serve as a data collection node that passes data up to the enterprise (such as Forward and Store). An MDC also can house virtual systems for high reliability and efficient utilization.
While large installation might require full-size racks/cabinets. The equipment layout in a rack or cabinet depends on the number weight and type of components, as well as segregation. Thermal loads is an industrial application are low, typically less than 25% of experienced data-center environment, for normal temperatures. Network cabling can be fiber-optic cabling or copper cabling. Regardless of the media selection, using a patch panel for connections in a MDC provides for essential testing and diagnostic points between equipment and connections for troubleshooting. The power and grounding must be supplied to the MDC. The incoming power feed typically include a UPS and one or more power outlet unit (POUs) to distribute power.
POUs includes features such as a power monitor to troubleshooting and diagnostic’s that are communicated via networks to displays. If you ground the MDC, it’s critical to optimize performance of all equipment located with the equipment located with the unit. This reduces downtime, caused by equipment failures and reducing the risk of data loss. Proper wire management is key for reliable connectivity and to speed up troubleshooting, changes, and diagnostic and moves. There are two areas in the MDC that requires wire management: Within the MDC- Patch cables and Input and Output to MDC- Horizontal cable. With this factor, bend radius control, identification, stack management, and strain relief creates challenges- leading to risk of downtime and troubleshooting.
An MDC helps secure networks, maintains flexibility and bridge gaps between the industrial and corporate networks while maintaining flexibility to disconnect the links of the network- if there is a problem. An MDC also protect the confidentiality control, integrity, and availability data. It facilitates the connectivity from the plant floor up to the enterprise, giving greater visibility into the process of identifying problems and making plans for the future.
