"We believe that the IBM Power Systems platform, running AIX, offers the best performance for Oracle databases. Upgrading to IBM POWER8 processor technology has been a huge step up. We’ve practically doubled per-core performance and can now draw on up to 4.5 TB of memory. These enhancements mean we can process and deliver data to the business faster than ever before."

—Dale McGowan, Enterprise Architect, Celero

"Our processes are tightly integrated, and manufacturing systems around the globe need seamless access to our business data. IBM Power Systems, IBM AIX and IBM DB2 are highly reliable, helping us achieve the extremely high availability we need for our business-critical SAP ERP application."

—Hermann Burtscher, SAP Basis Manager, Hirschmann Automotive

"With IBM AIX® on POWER8® technology, we have been able to partition the platform into a number of LPARs [logical partitions]. We can dynamically adjust the LPARs according to the needs of the business, adding processor and memory resources to help us cope with peaks in demand. And in the event that demand really rockets, we can activate dormant resources within the systems through Capacity on Demand, allowing us to scale up rapidly while keeping costs under tight control."

—Alwyn Jones, IT Business Systems Integration Manager, Isle of Anglesey County Council
