The Challenge

Paragon is a highly dynamic organisation that continues to grow both organically and through acquisitions. The Group launched its banking subsidiary in 2014, a year which also saw a massive 82 percent increase in its mortgage lending business. Ongoing growth and changes in the business naturally present challenges to the IT function, which must be prepared to handle whatever the future may bring.

The Northdoor Solution

  • Designed, sized and deployed new Power Systems landscape.
  • Completed non-disruptive migration from POWER7 to POWER8-based servers
  • Deployed IBM PowerHA, and Storwize V7000
  • Northdoor implementation and support services

Paragon has used the IBM i (formerly AS/400, iSeries) platform to support its core business systems for more than 30 years. Alongside these systems, which run on IBM Power Systems servers, Paragon has a large VMware landscape on Intel servers. The POWER7 servers were beginning to show the strain as workload grew. As this is the most critical element in their infrastructure, Paragon wanted to upgrade to ensure they were ready for the next phase of Paragon’s success. After reviewing the credentials of a number of potential implementation partners, Paragon decided to engage Northdoor plc .


  • Completed non-disruptive migration from POWER7 to POWER8-based servers
  • Accelerated overnight batch runs from three hours to one hour
  • Deployed IBM PowerHA, improving and simplifying high availability
  • Gained a stable, secure platform that will support future business growth
