<font size=2 face="sans-serif">I think there are two points here:</font><br><br><font size=2 face="sans-serif">A) RAID striping is probably a "loser"
for GPFS metadata. </font><br><font size=2 face="sans-serif">B) RAID mirroring for your metadata
may or may not be faster and/or more reliable than GPFS replication. Depending
on your requirements and assumptions for fault-tolerance one or the other
might be the winner.</font><br><br><font size=2 face="sans-serif">But .. if you're serious about performance
- measure, measure, measure and pick the winner. (And we'd like to know
what you found!)</font><br><font size=2 face="sans-serif">And if you want the best performance,
you'll probably need to (re)measure whenever you acquire new equipment.</font><br><br><font size=2 face="sans-serif">GPFS can do and does striping for high
performance when reading and writing metadata and data...<br></font><BR>
