The IBM eServer initiative is much more than a server brand. IBM is responding to the unprecedented demands being made on infrastructures - in terms of both workload and user expectations. IBM combines the strengths of its hardware, software, financing and services, along with the strengths of its business partners, to provide customers with new ways to build, manage and sustain e-business infrastructures.Universal servers are designed to be the most scalable to allow for maximum internal expansion (flexibility under the covers). The versatility of these machines lends itself to function as a tower or in a rack as necessary. Ideally suited for small and mid-market business customers, the xSeries 220 power-packed, affordable system delivers leadership technologies at today's price. The IBM xSeries 220 is packed with power to support file and print serving, workgroup productivity applications and e-commerce. To maximize your investment today and tomorrow, this server can scale up to two processors. Hot Swap technology on some models allows you to replace hard drives without powering down the system, while the optional Remote Supervisor Adapter lets you manage your system remotely.
