We are using several p7 frames and VIO.  We are consolidating all of our 
databases on six p7 frames to take advantage of CPU licensing and get rid of a 
pile of individual servers. 
So far no issues.

You might want to see this old thread I started on the same subject last year: 
   
http://www.freelists.org/post/oracle-l/Oracle-on-IBM-Power7 
   
I upgraded from P5 to P7 about 6 months ago and performance has been great 
except that we are actually allocating less CPU to the primary database server 
now
 since we also implemented a standby as part of the same project and had to 
transfer some of the CPU license over there.  With the decrease in CPU 
allocated to the primary DB server, concurrent activity slows down a bit during 
our weekly full backups, but other
 than that everything runs as fast or faster than on the old server. 
   
If you’re experiencing problems you might want to look into the TurboCore mode, 
or using Intelligent Threads technology to set it to just a single thread per
 core.  We didn’t use either of those here – our performance was fine with the 
default multi-threading.

Has anyone experienced hardware upgrade from IBM P6 to IBM P7. Any performance 
issues.
