Broadcaster and telecoms giant Sky operates a multi-channel and multi-platform television service in the UK, Ireland, Italy, Germany and Austria. It covers 20 million households and extending from TV to mobile devices, on linear and On Demand. It also offers a range of broadband and telephone services.
The company has recently rolled out a data centre infrastructure management (DCIM) solution across its UK data centre estate. The project was awarded to and led by leading data centre specialists Keysource, who were chosen in partnership with Schneider Electric.
Riccardo Degli Effetti, head of data centre operations at Sky said: “DC Operations is the foundation of IT at Sky and it needs to enable our business to grow. Uptime is the primary goal and responsibility of the operations team, but maximising capacity and efficiency while minimising our carbon footprint is high on the agenda too. As a company, Sky has set bold environment targets to reach by 2020.”
With the existing asset management solution approaching end of life, Riccardo and his data centre operations team sought a new solution which would help Sky understand how it’s servers could be better utilised, whether idle equipment could be safely turned off, and what impact that could have on available capacity throughout the data centre estate, as well as the energy consumption of the system.
“Capacity costs money,” Riccardo said. “The most efficient data centre is the one you don’t have to build. At Sky, we want to be able to measure what capacity we have as a resource, and understand how long it will be before we need additional infrastructure. We want to know which of our servers are working efficiently and which ones are not and therefore are candidates for decommissioning or further virtualisation. In a sense, PUE is not that useful to us – our key metrics are CPU utilisation and power consumption.”
Operating data centres throughout the UK, technology is at the heart of ensuring Sky can meet the demands of its business and customers both now and in the future. Sky’s IT estate includes over 1000 server racks located in a combination of Sky owned and operated facilities along with some co-located facilities. The range of challenges the operations team faces include: delivering service availability with the highest levels of performance, improving resource and operational efficiency and lowering costs.
The exciting and ambitious aim of the project is to raise awareness of IT usage across the whole of the Sky business. It is also one which Riccardo Degli Effetti believes will enable DCIM to show its full potential “The objective is to be at the forefront of innovation – not to follow but to lead – and this project will achieve that”.
By developing the requirements further to encompass a range of other desired and required functionality, Sky produced a performance specification and went to the market in a competitive tender. The process involved eight potential suppliers, but Keysource saw the opportunity to focus not only on the software but on the project outcome as a whole and the need for ongoing collaboration with the rollout of further functionality. The partnership between Keysource and Schneider Electric provided Sky with the benefit of a leading data centre specialist working together with an industry-leading DCIM solution provider.
With such a transformational project it was crucial to get all relevant people engaged and on board with the overall project objectives and timelines. So, once appointed, Keysource’s initial focus was to identify the key stakeholders across all businesses and establish the respective roles.
Keysource organised several workshops where the proposed approach to the project was modelled, the core functionality of the toolset was explained and demonstrations of its impact on current systems and ways of working could be discussed.
The workshops incorporated demonstrations and virtual examples of real infrastructure to help visualise the overall end goal. By getting early buy-in, Riccardo’s team and Keysource could ensure that stakeholders were fully on board with the plan, shared ownership of what was being proposed and were positive about the future potential. Rob Elder, Director at Keysource said, “With any roll out of DCIM, the success will be derived by what is achieved as a result of the data from the tool, not by deploying the tool itself.”
The next step was to ensure the relevant technical, security, network and operational resource was available from all sides to plan the implementation and scope of integration. Spanning multiple systems and teams, more than 30 subject matter experts were required at various stages to ensure a successful and ultimately workable outcome.
Phase 1 commenced in June 2014 and was delivered in early October 2014 for the pilot facility. Within this time all aspects of the planning, engineering and development, as well as deployment and validation testing, were conducted.
The second phase, currently being implemented, involves integrating the DCIM solution with the BMS across all sites. This will unlock further benefits and functionality, and will require further collaboration and interfacing with a range of service and solution providers.
Prior to the implementation, Sky had been using a number of different tools, which were not integrated; therefore rendering the capacity and performance management of the data centre estate very time consuming. Furthermore, the incumbent asset management tool did not have some of the required functionalities; it was apparent that a new approach was needed.
The Schneider Electric StruxureWare for Data Centers software suite includes a comprehensive DCIM toolset combined with the integration and functionality to make it central to Sky’s data centre operations.
Out of the box components included asset management, change management, capacity planning, it optimisation and BMS integration. Keysource ensured that StruxureWare was populated from existing data and interfaced with other business tools for service delivery and ticketing. The aim was not to alter the way Sky ran their operations to fit in with the new tool, but rather to develop an approach which optimised and streamlined the whole process. This resulted in a single dashboard in which assets, racks and BMS data can be viewed through a single screen.
One of the key aspects of the project, covered by the functionality of the IT Optimize software module, was to give Sky the ability to identify assets through CPU utilisation which could be candidates for virtualising, re-provisioning or retiring. Armed with this insight the operations team could go back to the different parts of the business, who were responsible for the specific platforms or applications, and engage with them about how their IT was put to use.
Impact failure analysis through linking the BMS to the IT assets enables real time changes in status or availability to be flagged via alarms through the tool. Either due to a planned or unplanned event, workloads can be deployed or managed based on suitable data centre capacity and availability on current conditions.
Combined with real time data the operations team out in the field can access the DCIM data and tools through mobile devices. Providing a dashboard and the ability to drill down into different areas improves service delivery by allowing for better more informed decisions and reduces the need for duplication. Despite the range of operational and technical benefits the real driver comes back to efficiency and reducing cost.
Riccardo Degli Effetti believes that the industry-standard measurement of data centre performance, power usage effectiveness (PUE), has limitations when it comes to actually showing how usefully a data centre is performing, relative to its specific IT workload. “PUE has changed the industry, but it is not a final indication. It doesn’t tell you whether a data centre is doing something useful or not. To do that, you need to go very granular on the IT, and previously where we had the capacity to do that, we didn’t have the intelligence in the tools to enable it,” he said.
The benefits include
Maximised efficiency of the existing data centre estate, avoiding building new data centre facilities.
Enabled centralised holistic monitoring of whole the data centre estate via a single dashboard, saving time.
Reduced human error and improved workflow through integrated change management.
Provided full visibility of server hardware utilisation correlated with power consumption for long term planning.
Provided business intelligence through reports showing utilisation, performance and capacity planning.
Improved service availability and operational performance through impact alerts and mobile apps.
Achieved compliance and reduced time with a full audit trail.
Lower carbon footprint can be achieved via automatic notification of server under-usage.
Engaged users and informed them of potential improvements in terms of performance / usage, budget and carbon savings from better provisioned resources.
