Page 6:

"Each card houses two POWER7
processors" should read "Each card houses one POWER7

Page 13: The streams are crossed!

The lines for memory channels B, C, and D should be distinct. The image makes it appear as though these three memory channels are somehow connected.

@Mark Good eyes. The lines *were* unique, but as you pointed out overlapping. The next update wil have the updated image and the single POWER7 per card update.

Pages 28 & 29, section 2.1.1
You have given the POWER7 processor rather a lot of L2 cache.
I think "256 MB" should read "256 kB" in 2.1.1 and in table 2-1 shouldn't it?

$ lsattr -El L2cache0
size 256 Size of L2 cache in Kbytes False

The RAID section is incomplete and not clear. Please expand the internal RAID discussion, FC 5923, etc.

The book still was listed on the "System i" side on, it's true? :-)

Thanks for the comment. Since these systems support System i and System p, we had them put on those lists. I've updated the list so it is just Power Systems to avoid confusion.
