After talking to Phil about this some last night, the one thing that came to my mind was containable growth with scale!
While working with customers, visiting datacenters and reviewing workloads for consolidation I've sadly yet to come across a case where mainframe growth is causing the need for more power then an areas grid can provide, or the floor space with people required to accomodate server sprawl. If you map out your datacenter, look at the z footprint, understand the services it's providing for your business and then really dig into and understand the true cost of everything else. Make sure you include the cost of moving, growing or building a new datacenter into that "cost of everything else" model you're creating, unless you really have unlimited reasources to work with. z Systems is of course not the answer for everything. Some x86 server sprawl can also be tamed by looking at Power. With our Linux everywhere and open directives, Power systems are starting to be used by customers that were born on x86: http://openpowerfoundation.org/ Hopefully this information is helpful, Kurt Acker Cell: 607-348-8197 IBM Smarter Planet, Smarter Data Centers Virtualization and Enterprise System Management Technologies ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
