p and i systems reliability

[Pete Helgren <Pete@xxxxxxxxxx>]

I haven't seen this referenced here and I came across this while 
scanning the weekly SANS bulletin. I was a reference to an article from 
The Register:  "IBM Power: good. Windows: not so much"

"Among the customers surveyed by ITIC, IBM's Power Systems running AIX 
experienced (this includes older System p and pSeries iron) the least 
amount of downtime per year, when averaged across all customers using 
these platforms. AIX shops reported an average of 0.42 Tier 1 incidents 
per year and 0.34 Tier 2 incidents, and not one customer reported a Tier 
3 outage on their AIX boxes. The Power Systems machines (and this 
includes older System i and iSeries iron) had an average of 0.56 Tier 1 
outages per year, 0.44 Tier 2 outages per year, and 0.12 Tier 3 outages. 
So in 2009 at least, the i platform fared a little worse than the AIX 
platform running on Power iron."

Pretty much a "duh" for us i folks but *just* in case some of you are 
fighting the "switch to Windows" battle, it might be some additional 
ammo for staying on the i.
