Oracle and SUN "Sun announced Niagara 2 the other day, an evolution of the older Niagara 1, now called the UltraSPARC T1. From the 10000-foot view, it all looks quite familiar, but once you delve into the details, it quickly becomes apparent that almost everything has changed."

Performance of the T1 processor really depends on the workload you throw at it. Every one of those you listed, we've thrown at it, and it has walked away hands down the winner. We're replacing the majority of our NetBackup infrastructure with T2000s, because they kicked everything else's rear ends up and down the evaluation track (Dell PE2950 and HP DL585 running either Windows or Linux). In one of our web-based application services, we're replacing V1280s with T2000s and seeing performance *increases*. For LDAP, we've seen 3:1 better performance over a V440 class system.

Haven't had a chance to play with LDom on the T5220, so I can't comment on how it changes the performance. However, considering that very few server workloads are actually that FP intensive, it rarely matters.
