One of the more interesting attributes is that the machine will do everything possible to keep your work moving as best it can even if there's a double MRU failure. It can slow down the processors to reduce heat. WLM (assuming z/OS) is still in control, so heat-related forced slowdowns will tend

This kind of also ties into the *gas gauge* available for z9 with driver upgrade. I thought this little pdf interesting. ftp://ftp.software.ibm.com/systems/z/pdf/z9_Gas_Gauge_Driver_manual.pdf under http://www-03.ibm.com/systems/z/advantages/energy/index.html Timothy Sipples

Google IBM z9 cooling. Also check out http://www.research.ibm.com/journal/rd/511/harrer.pdf. The z9 has a MRU, modular refrigeration unit. Joel M Ivey [EMAIL PROTECTED] wrote: What safety guards are there on z9bc hardware to prevent over-heating? (Such as when the building's coolers are
