[SunHELP] E3000 & E3500 wierd situation

[Stefan Molnar]

Well, Two things scream out as proformance hitters.  Going from 6
spindles to 4 spindles is one.  Also RAID 5 will hurt on writes, and
RAID5 with Oracle does not give that great proformance anyways.
RAID0+1 is better.   Are you using the internal FC bay on the 3500
or something like a D1000 externaly?
