This white paper describes six real case studies that show the current environment, alternative outline solutions and the financial benefits of consolidating and integrating UNIX and Microsoft Windows servers. One major lesson learned from these cases is that the type of savings achievable vary considerably by target platform. In some cases, the hardware is dramatically reduced, in others the software, in others the people productivity is significantly increased. tech news

Today most large enterprises have thousands of UNIX and Microsoft Windows servers. But how do you begin to analyze this quantity of servers? This paper contains actual data from various major clients and is based on practical experience of many IT consulting engagements. It describes many of the key factors to be considered and their interpretation. In particular it shows a roadmap of activities and analysis that can peel the layers of the onion and reveal significant technical opportunities to help reduce the cost and complexity of the server infrastructure. tech news

Calculating the total aggregate server load in the 'wrong' way can result in significant (>2 x) over-provisioning of total server capacity. This is an especially important consideration when calculating the total capacity required for a single large server needed to virtualise and replace many small, often under-utilized servers. This paper illustrates the method and useful graphical representations of some of the more important considerations. tech news

This paper is a comprehensive guide covering the IBM eServer p5 570 UNIX servers. It introduces major hardware offerings and discusses their prominent functions. This paper expands the current set of IBM eServer documentation by providing a desktop reference that offers a detailed technical description of the p5-570 system. The IBM p5 570 rack-mount server is designed for greater application flexibility, with innovative technology, to capitalize on the e-business revolution at the midrange level for server environments. tech news

This paper is a comprehensive guide covering the IBM eServer p5 550 UNIX servers. This paper expands the current set of IBM eServer documentation by providing a desktop reference that offers a detailed technical description of the p5-550 system. The IBM eServer p5 550 deskside and rack-mount servers are designed for greater application flexibility, with innovative technology, to capitalize on the e-business revolution at the entry-level or server environments. Introduced with the POWER4 and POWER4+ technology in 2001, available from the 1-way entry-level through the 32-way high-end pSeries systems, the IBM POWER architecture achieved a new stage of capability characteristics by including features such as logical partitioning (LPAR). tech news
