Avoided by whom? By HP, may be, that just recently started to sell it in DL1xx (180) line and still has no 5100-based machines in DL3xx line, but not by customers and not by other server vendors.
IMHO, HP should replace DL320 with 1S 5100-based gear ASAP.


replacing the 8x2GB for 4x4GB modules costs $202, for the LP versions it's

Is the performance test used in SpecPower identical to regular Jbb2005? 338,577 sounds a bit too good to believe. The best official Barcelona score on BEA JVM=219,269.
338,557 is even a bit higher than 2x3.33 QC Penryn on IBM JVM.
