Infrastructure Group

The Infrastructure Group are a team of multi-discipline software engineers, system administrators and researchers. They design and build the testbeds in use in TSSG to meet current and future research needs. Their role is to support and enable experimenters get the most out of the computing resources and testbeds they use. They also operate and manage TSSG’s High-Density Water-Cooled Data Centre facility which is home to many Testbed Infrastructures such as Unified Communications, IoT, Cloud, SDN/NFV, and SDR Testbeds, as well as an AI cluster and ICHEC’s Super Computer.

In addition to their testbed work the Infrastructure Group work on a range of EI, EU, InterReg and SFI projects ranging from security, radio technologies, advanced networking protocols, automation and virtualisation, as well as building prototypes for SMEs.

The Infrastructure Group take a DevOps ethos to everything they do and as such heavily use Software Defined Infrastructure (SDI), including Software Defined Networking (SDN), Software Defined Storage (SDS), and Orchestration as means of delivering services quickly and effectively.

Data Centre

The TSSG house and operate their own Data Centre facility to support over 50 concurrently active ICT research projects through the provisioning of Internet services, Cloud Computing resources, an AI cluster, and project bespoke testbeds (such as Unified Communications, SDN/NFV, Internet of Things, etc.) and research equipment.  The TSSG Data Centre also houses research infrastructure for other research groups and centres, such as ICHEC’s Super Computer ‘Kay’ and CONNECT’s Pervasive Nation Testbed.


The Data Centre was designed for functional modularity, with separate rooms for servers, networking equipment, UPSs and batteries, with the generator and cooling equipment located outside. Each room in the Data Centre is designed to use the best cooling option for that function. For example, the UPSs and batteries are located in exterior rooms using natural ventilation and small fans for cooling.


As a result, the Server Room of the Data Centre has no hot or cold aisles. All the heat/cooling is contained inside the server cabinets, making the server room both comfortable and quiet.

The Data Centre has an IT power load of 300kW, with cabinets engineered to house 30kW of IT equipment. 1+1 300kW UPSs and an 800kW Generator provide the backup power. The Data Centre uses Rittal LCP technology, which uses chilled water (at 15°C) and provides free cooling 80% of the time.


As the Data Centre is Water-cooled, higher densities than traditional air-cooled systems can be achieved allowing a smaller overall footprint as more servers can be packed into the cabinets and there is no need for the traditional CRAC units in the server room.

The TSSG Data Centre currently supports over 160 physical servers, providing more than 1,000 cpu cores for processing and 400 virtual servers for cloud computing.  In addition, there is over ½ PB (that 512 TB) of Data Storage, and ~3,000 network ports. All of which provide a high-level of interconnectivity and flexibility for TSSG’s research projects.
