The Big 3 project has successfully concluded

(12 March 2021)

Following on from the delivery of the highly successful first phase of The Big 3 in 2019, CIS has undertaken and now completed the second phase of the project to further enhance the University’s IT network. Director of Operations, Crispin Bloomfield said, “We have now completed both phases of the Big 3 project which has given us a much more robust, resilient foundation from which our IT services can grow in the future. We know that in the coming decade, the demands on our network to provide reliable, fast connectivity are only going to increase. By having this solid infrastructure in place, we will have the confidence and capacity to ensure this can happen”. Watch our short video to find out more about The Big 3 and how we’ve improved the University’s IT infrastructure for the future. Read on for more information about The Big 3.

The Big 3 work has now been successfully concluded on time and within budget, resulting in many impressive benefits that will future-proof the University’s IT infrastructure.

By simplifying the design of the network, we have provided more bandwidth and a scalable architecture that simplifies management and enables future growth.

The Big 3 Data Centre and Core Network brought forward planned investment to upgrade the University’s datacentre networking equipment and our ability to support the future needs of the University for core activities such as research and teaching.

We can now connect buildings, such as our new Mathematical Sciences and Computer Science Building, at up to 100Gbps. Coupled with our work at a national level with Jisc, we will be in a strong position in future to bid for research that is dependent on fast internal and external network connectivity.

Work also took place to replace old switches, ensuring there were no vulnerabilities or weak links in the chain. This work has also improved the time it takes to retrieve documents from the University’s servers, due to simplified routing. This has enabled us to press on with the current Wi-Fi replacement project that is currently bringing next generation wireless connectivity to the whole campus.
