I'm a huge fan of thin interrupts, which (it turns out) we depend totally on to 
power our sandbox sysplex. However, we turn on thin interrupts on both sides of 
the share: sandbox and production. In the prospective case (single CEC only), 
the 'other side' of the share would be MVS, which has no notion of CFCC. It 
would be playtime for two toddlers, one well-schooled in sharing, the other 
clueless. An interesting prospect in any case.

BTW Tom's sig line induced me to curl up for a while with Wikipedia. We in the 
Southern 48 were never properly introduced to the Dead Dog Café.

A Coupling Facility Logical Partition can run on shared CPs.  It does not 
require an ICF engine.  Normally I would not recommend the use of a CP, but if 
you are careful not to use the CF a lot, and use DYNDISP=thin, it can be quite 
useful. If all the connectors to the CF are in the same CEC, then there is no 
real CF link hardware required. Connecting multiple CECs will require 
purchasing hardware CF links.

This box is for DASD mirroring (SDM) and system recovery. It has only one CP 
except when CBU is fired up. No data host at all under normal circumstances. As 
modestly priced as a CF might be, I don't think we could sell the idea just for 
the benefit of sysprogs.
