I don't think we need the top tier SLA.

Is this also considered the person who would triage issues with XenRT or 
osstest?
Meaning they would look at the test results and figure out where the bugs are 
happening?

CS: yes to troubleshooting problems with sw and hw test infrastructure, but no 
to detailed triaging of test results which would be responsibility of person 
invoking  the test run (although could support it).

I am not sure what that is. Is this an upfront cost to setup the network, 
switches, terminal servers, remote power on/off setups, DHCP, etc? I presume so.

CS: yes, and initially B could probably reuse the hardware in A

These would be one-time costs right? And I presume they could also be 
eliminated if vendors (AMD, Intel, Oracle, ARM) provided the hardware?

CS: yes, although there would be repeat costs if want to grow capacity, add new 
server/processor types etc.

With these numbers I am tempted to advertise my basement as a perfect place for 
it :-) Much cheaper costs - though there would be an upfront cost to get a new 
100AMP circuit installed.

Free cooling thanks to New England weather.

(and yes, my basement already has two racks of machines that do testing every 
night).
