[Info-vax] ITIC 2014 - 2015 Global Server Hardware, Server OS Reliability Report (was Re: BASIC compiler in the hobbyist distribution)

Here's the basis for the statistics that were referenced in that Lenovo 
document — the URL that was cited in the Lenovo document over at IBM is 
stake, so here's the present location:

http://www.lenovo.com/images/products/system-x/pdfs/analyst-reports/XSL03126USEN.PDF 


That graph was for four or more hours of outage per server per year.  
For "over four (4) hours of per server/per annum unplanned downtime."

The information in that presentation is interesting, and is rather more 
readable than that Lenovo slide, too.

Interestingly, Integrity reportedly had 3% with outages over four 
hours, per box, per year.  So better than ProLiant, per that report.

The x86 outages are attributed to folks that buy cheaper boxes and/or 
that run those boxes for years: "The breakdown in x86 server 
reliability generally occurs not because of any inherent flaws in the 
underlying server hardware because x86 customers tend to “push their 
luck” and retain their server hardware for 4 1⁄2 to sometimes 6+ years 
without retro-fitting, upgrading. Hence, the business ends up 
overloading old, outmoded servers and start to experience availability 
problems. This is particularly true of organizations that purchase 
entry level or inexpensive commodity servers."

Much love for Xeon E7 V2, too.
