Response to Jeff Savit Blog
As part of the announcement of z10 IBM made some marketing claims about the large number of distributed Intel servers that could be consolidated with zVM on a z10. The example cited used Sun rack optimized servers with Intel Architecture CPUs. Sun Blogger Jeff Savit objected strenuosly to the claims mainly because of the low utilization assumed on the Sun machines that the claims compared to. You can read it here:
http://blogs.sun.com/jsavit/entry/no_there_isn_t_aI responded, he responded. When I was out of pocket for awhile and did not respond soon enough and his blog cut off replies on that thread. I am putting my latest response here. Thanks to Mainframe blog for providing the venue to do so. My latest responses to Jeff are in blue italics.

This diaglogue was very interesting. As a user in need of a means to compare zLinux to other options, I need be able to do so without making an investment in z. I've been fairly sucessful in using the public benchmarks that Jeff refers to in plannng a virtual infrastructure around VMware or in implementing large complex applications on Sun. We'd like to explore Z but not knowing how to translate our workloads into Z capacity is turn off.

Larry MC. I can help you compare z to other servers. IBM has the capability to compare z to other machines in a variety of ways. You can do two things. First, ask IBM for a discussion about "Fit for Purpose" with an IBM System Architect or cSM (SA). These folks come from a variety of backgrounds but work on cross platform archietctural decisions to find "Fit for Purpose". Second you can get hold of my CMG paper on relative capacity which will be presented at CMG2008 and published in 1Q09. Third you can contact me through email at IBM. Put Temple III in the field of the "employee directory" on the IBM website to get the email address.

I guess they have not been hyper tuned and specifically designed for. They have a better chance of representing reality.

The hyper tuned system is going to be the future. This writeup was perfect, I could,t have expressed it better myself.
