Data Centre - Consolidation

Aberdeen University, Robert Gordon University, Aberdeen College and Banff & Buchan College.

Existing data centre facilities across all four institutions inadequate for future requirements, and unsustainable based on existing performance.

Introduce a shared service approach to data centres, backed by energy efficient design (North East of Scotland Shared Data Centre).

Carbon emissions reduced by 1,400 tonnes per annum (£250K per annum).

  • First Prize (Public Sector category) Computer Weekly European User Awards.
  • Data Centre Project of the year, Computing UK.

Data Centre - Virtualisation

Sheffield Hallam University

Excessive server count leading to space and outage problems.

Replace 120 physical servers with 300 'virtual' servers.

  • More services for less cost - £2500 saving on hardware each time a virtual machine is deployed.
  • Better server utilisation (50-70% versus an average of 5% for physical servers).
  • 20% saving in energy consumption.

Data Centre - Cooling

Fife Council

Existing air conditioning in data centres is 10 years old and does not take into account significant developments in cooling over time.

Redesign the layout of racks to reduce the amount of cooling required (switch to "cold isle" layouts and introduce a "free cooling" system to filter cold air from outside the building).

Electricity bills reduced by £42,000 per annum (equating to carbon savings of 135 tonnes per year).

Print Reduction

Department For Work and Pensions

Unsustainable printing costs and energy usage in printing.

Introduce a managed print service - 30,000 legacy printers replaced with 8,200 energy star rated multifunctioning devices.

Electricity consumption reduced by 63%.

Financial savings via default double-sided printing.

Help desk calls halved (and 90% reduction in the number of site visits by engineers to deal with faulty printers).
