At PSR, IBM mainframes are our business—our only business. Unlike other vendors, we don't also dabble in blades and PCs and other products. We're 100% focused on selling IBM System z processors, system software and related storage hardware—and on providing unmatched procurement, migration, support and recovery services for System z-based data centers.

As a result, we're truly mainframe experts. Our staff has over 300 years' collective experience on IBM mainframes. Whenever IBM introduces a new mainframe product, we purchase one for ourselves, test it rigorously, and put it to work in our own data center. We don't sell anything we don't use ourselves.

Most important, our exclusive approach ensures a successful purchase and implementation. Our thorough assessment of your data center and detailed knowledge of IBM's pricing structure ensures you'll get the right equipment for the best possible price. And our exclusive ServerAssure and SystemBuild processes—in which we configure, integrate and test your hardware or system software at our site before we deliver it to yours—ensures that your new mainframe solution will be ready to run, without incident, from the moment we install it.
