I''m trying to boot a PV guest using the "old method" of passing kernel= and ramdisk= and it appears to work fine with a "small" initrd but not with a "large" one. (Small is 4MB, large is 154MB.) I''m sure both of the initrd''s are properly gzip''ed etc. Unpacked, the large one approaches 400M. By doing some kernel startup debugging, it appears that the large initrd never finds its way into memory. Or at least not completely or properly. So I''m guessin...

...some sort of write bottleneck and I am not sure how to solve it. I was hoping for a write speed of 300MB/second. With ZFS on top of a firmware managed RAID 0 across all 12 drives, I hit a peak of 200MB/second. With each drive exported as a LUN and a ZFS pool of 6 pairs, I see a write rate of 154MB/second. The number of drives used has not had much effect on write rate. Information on my pool is shown at the end of this email. I am driving the writes using ''iozone'' since ''filebench'' does not seem to want to install/work on Solaris 10. I am suspecting...
