When the significant Intel/zSeries annual price/performance improvement gap is overlaid on these projections, it becomes clear that any business case for mainframe Linux will evaporate by 2005/06, in the face of the Linux on Intel juggernaut.</p><p>(Meta Group, Mainframe Linux Server Consolidation: The Near-Term Business Case, Delta 2107 Mar 03)TCO versus TCA!</p></li><li><p>Action Item: Investigate all options to consolidate. Closely evaluate the migration costs, all assumptions (including staffing efficiency and over-provisioning for peak workloads), availability requirements and alternative mechanisms for reducing TCO.
