Janne Hankaankorpi says: “We knew that accelerating our reporting and streamlining our operations would enable us to deliver an even better experience to both our B2C and B2B customers.”
Reinventing digital reach to customers
DNA set its sights on modernizing its core IT environment to achieve the performance it needed to support rapid reporting. The company chose to start afresh and consolidate to two new datacenters, and selected IBM Power System S822 servers and IBM® FlashSystem® 900 storage to provide the platform for its growing Oracle Database and Oracle applications environment.
Janne Hankaankorpi explains, “Over the years we have developed a very strong relationship with IBM, and past experience has given us immense confidence in IBM Power Systems™. The price was also highly compelling: if we had gone with another solution, license costs would have been triple what they were with POWER8® processor-based systems.
“The project went smoothly, just as we expected. Working with IBM is always a positive experience.”
DNA runs its Oracle Database in one main datacenter supported by a secondary datacenter. The two sites operate in active-active and active-passive set-ups, depending on the applications in use. In addition, existing IBM Storwize® V7000 storage capacity has been extended with new IBM FlashSystem 900 storage solutions.
Arto Pelkonen, Specialist at DNA, says: “By using FlashSystem storage for our most critical applications, for example our billing system and our customer-facing services, we can improve response times and ensure processing is always complete.”
DNA virtualizes its storage with IBM Spectrum Virtualize™, and manages the virtual storage using IBM Virtual Storage Center, which includes IBM Spectrum Control™.
Arto Pelkonen comments: “Whenever we renew our storage hardware, we have to move very large quantities of data onto the new systems, and we have to achieve this without disrupting ongoing processes. We’ve found IBM Virtual Storage Center to be the best data migration tool on the market. It provides a single point of control for all storage resources, making it easy to move massive volumes of data.”
To compress the Oracle Database onto fewer physical disks, DNA takes advantage of IBM Real-time Compression™. Designed from the ground up to compress active primary data, IBM Real-time Compression supports workloads that are often not candidates for traditional compression solutions, enabling storage administrators to free up disk space without having to clean up or archive data.
“IBM Real-time Compression is hugely cost-effective—delivering the greatest savings in the entire project. The solution enabled us to shrink our Oracle data by 70 percent, dramatically reducing our storage space requirements and operational expenses.”
Connecting to satisfied customers
With the new IBM solutions in place, DNA has successfully modernized its IT infrastructure and is realizing its vision of having the most satisfied telecoms customers in Finland.
Janne Hankaankorpi takes up the story: “We have completely eliminated reporting delays. We’ve cut load time for our overnight batch processing by approximately 30 percent. Daily reports are ready by 8 am every morning without fail, so decision-makers can get to work straight away, without having to hang around waiting for reports. This enhances our agility and enables us to react to new opportunities as soon as they arise, capitalizing on successful campaigns more effectively than ever. Reporting has improved across the board, not just for marketing—all internal stakeholders are very happy.”
Arto Pelkonen adds “DNA is capturing significant cost savings as a result of the project. We’ve already reduced our data center footprint considerably. This has resulted in great savings in terms of energy costs. We’ve cut the footprint of our data warehouse to a single, standard 19-inch rack—roughly an 80 percent reduction. We’re still in the process of consolidating our various datacenters, and the more we consolidate the more we will save.”
Looking to the future, the flexibility of the Power System servers will enable DNA to incorporate new applications, and scale up to support increasing data volumes as the business grows.
Janne Hankaankorpi concludes: “Now that we have Oracle Database running on state-of-the-art IBM Power Systems servers, we’re better positioned than ever to deliver outstanding levels of service to all of our customers.”
