Hi Laura, great information [shown below] and an excellent perspective
in outages. A couple of points: 1) IBM has unified their Power based
product lines from the old "p" series and "i" series lines into the
Power Systems. Any new Power 6 based system would be considered a Power
system if it were running AIX, Linux or IBM i (did you survey any IBM i
customers?) 2) Did you take into consideration the scalability of Power
Systems vs Intel. Typically you will have 10s or 100s or even 1000s of
Intel servers vs 1 or 10s of Power servers. If each Intel server suffers
a 2-3 hour outage, the impact on a business is significantly higher than
if fewer Power System iare down for 15 minutes.

Hello,
Thanks for your feedback. Yes, we did survey IBM i customers. And the
full Report does go into detail regarding : 1) the workloads of the IBM
(and also HP and Sun SPARC) systems being much heavier by 35% to 60%
than a typical Wintel box and OS and 2) the full Report does not the
greater impact and domino effect of downtime when the less powerful, but
more numerous Wintel systems running Linux or Windows are down. I'm
happy to discuss with you in more detail. If you have any further
questions, feel free to contact me directly via Email at
ldidio@xxxxxxxxxxxxxx
Best Regards,
Laura

r-os-reliability-survey-results/
For the second year in a row, IBM AIX UNIX running on the Power or "P"
series servers, scored the highest reliability ratings among 15
different server operating system platforms - including Linux, Mac OS X,
UNIX and Windows.
Those are the results of the ITIC 2009 Global Server Hardware and Server
OS Reliability Survey which polled C-level executives and IT managers at
400 corporations from 20 countries worldwide. The results indicate that
the IBM AIX operating system whether running on Big Blue's Power servers
(System p5s) is the clear winner, offering rock solid reliability. The
IBM servers running AIX consistently score at least 99.99% or just 15
minutes of unplanned per server, per annum downtime.
Overall, the results showed improvements in reliability, patch
management procedures and an across-the-board reduction in per server,
per annum Tier 1, Tier 2 and the most severe Tier 3 outages. Among the
other survey highlights:
* IBM leads all vendors for both server hardware and server OS
reliability as well as the fewest number of Tier 1, Tier 2 and Tier 3
unplanned server outages per year. IBM AIX running on the System p5s had
less than one unplanned outage incident per server in a 12 month period.
More impressively, the IBM servers experience no Tier 3 outages. Tier 3
outages are the most severe and usually involve more than four hours or
a half-day worth of downtime and can also result in lost data.
* HP UX also performed well though HP servers notch approximately
25 minutes more downtime than IBM servers, depending on model and
configuration - or just under 40 minutes per server, per annum downtime.
* IT managers spend approximately 11minutes to apply patches to
IBM servers running the AIX operating system, which is again, the least
amount of time spent patching any server or operating system. The open
source Ubuntu distribution is a close second with IT managers spending
12 minutes to apply patches, while IT managers in the Apple Mac OS X
10.x. Novell SuSE and customized Linux distribution environments each
spend 15 to 19 minutes applying patches.
* IBM also took top honors in another important category: IBM
Power servers and AIX experience the lowest amount of the more severe
Tier 2 and Tier 3 outages combined of any server hardware or server
operating system. The combined total of Tier 2 and Tier 3 outages
accounted for just 19% of all per server, per annum failures.
* Microsoft Windows Server 2003 and Windows Server 2008 showed the
biggest improvements of any of the vendors. The Windows Server 2003 and
2008 operating systems running on Intel-based platforms saw a 35%
reduction in the amount of unplanned per server, per annum downtime from
3.77 hours in 2008 to 2.42 hours in 2009. The number of annual Windows
Server Tier 3 outages also decreased by 31% year over year and the time
spent applying patches similarly decline by 35% from last year to 32
minutes in 2009.
* This year's survey for the first time, also incorporated
reliability results for the Apple Mac and OS X 10.x OS platform. The
survey respondents indicated that Apple products are extremely
competitive in an enterprise setting. IT managers spend approximately 15
minutes per server to apply patches and Apple Macs recorded just under
40 minutes of per server, per annum downtime.
