Project Overview

This project provided Aruba with an advanced real-time monitoring and control system for its new Global Cloud Data Center (ANSI/TIA 942 Rating 4 compliant), the largest data center campus in Italy (200.000 sqm).

Problem

Aruba wanted to build a modular and flexible data center designed primarily to offer its Italian and International customers colocation services. Aruba needs to control all its subsystems from a single fully integrated system.

The system includes:

• Data center electrical power distribution (medium voltage - low voltage) and continuity (UPS, batteries, and gensets)
• Renewable electrical power production (hydroelectric and photovoltaic)
• Data center firefighting and flooding (with more than 100 sensors)
• Geothermal use of groundwater for data rooms cooling with traditional chillers in backup
• Ambient conditions monitoring (temperature, humidity, air quality)
• Building automation (lighting, HVAC, and access management)

All this data collection and interaction must lead to:

• Plant monitoring
• Remote commands
• Automatic management procedures
• Real-time alarms, pipelines, and notifications
• Long-term historian
• Power consumption analysis
• Data center KPIs
• Maintenance

Solution

Ignition allowed MTech to easily connect to all the devices installed in the plant and collect a huge amount of data in a structured way (using UDTs). Developing PLC software with Ignition UDTs and templates in mind allowed MTech to create PLC elements using an object-oriented approach.

Some mandatory customer requirements were:

• Detailed graphic interface
• SQL database data storage
• Multiple concurrent clients access
• Structured alarm notification

All these were fulfilled by Ignition, and unlimited tags/clients licensing gave space for future (and really fast) growth of the system.

The solution includes:

• Audit log
• Scheduled data export (reports)
• Third-party software data access

The next step will be integrating Ignition Perspective (keeping in production the previously existing Vision pages) to give universal access to the system, especially from mobile devices. This integration will lead to new features, such as interactive maintenance.

Results

Ignition has shown its capability to be a flexible platform for creating powerful and beautiful HMIs, allowing developers to use incredible scripting with ease. Data collection is extremely reliable, and level of performance is satisfactory for end users even with massive amounts of data (billions of historical samples).

Online changes have guaranteed that Aruba will not need to interrupt its services in any case. Final cost of the entire Ignition solution is less than any “traditional” SCADA solution.
