On Monday December 6, Marcy Cortes arranged the electrons to say:
In my SHARE user experiences presentation I usually warn people
against even
answering that question.
Stephen has a good approach to an answer.
My boss thinks I'm a smart xxx when I turn it around and ask him
How many = rocks can
how many servers can run,
effectively, on 1 IFL for your comparison...

Here we go again!

z/Linux since 2003!
Our zVM licence has been recently cancelled, and I have just had a request
This might be obvious, but when attempting to estimate the number of servers
you can load on a Z10 - keep in mind that a z10 EC is aprroximately 40%
faster than a z10 BC.

John,
I've built the cost model and justification for zLinux at BBT and can
share with you what I have. Feel free to contact me directly at
rbur...@bbandt.com. I can send you some spreadsheets and other info.
We have 2 z10 EC machines and 4 zVM LPARs - 1 prod LPAR on each of the
z10s, 1 test

Our zVM licence has been recently cancelled, and I have just had a request from
our Enterprise Architects for some costing for z/Linux as they need to compare
server virtualisation
If you are comparing VM and VMware, I would estimate that 1 IFL will
support about the same load as 5-10 HP blades running ESX. How many
virtual severs will VMware support? Depending on the workload sometimes
only 1 sometimes 70 per ESX. How many will VM support? Between a few and
a thousand per

How about savings in power consumption. If configured correctly a
virtual server won't cost you anything. Well, hardly anything.
Running a dedicated server you must size the server for it's peak load.
In VM you run multiple servers and if their peak load doesn't overlap
you don't need to size for

1. Disaster recover is much easier on the mainframe. In effect, no matter
what hardware is replaced with what hardware, it is all the same. With PC type
servers, the hardware, hence the software drivers are constantly changing.
