Can you describe the hardware of the private cloud
and the hardware of the non-cloud machine in the
location where you were involved in the installation
or configuration?
I would like to  know what is being compared to what
when claims of doubling the performance are made.

For example if the cloud has a total of 400 cpus,
100 TB of mirrored raid 5, 200 ports of 10GigE, and
1600 GB ram,...etc...etc
is the performance benchmark compared to a similarly
equipped large scale SMP machine with same type and
speed of cpus and ram, same type and size of storage,
same OS and same app, and same backplane as the
machines in the cloud?
