Sun and VMware just published benchmarks of ESX Server 3.0.2 running on a Sun Blade X8440 with 4 x dual core AMD Opteron CPUs (3GHz).
It’s interesting to report that the system achieved slightly worse performances than ESX Server 3.0.1 on Dell PowerEdge 6950 with a very similar configuration.
With this analysis Sun joined Dell and HP in VMwark adoption, the VMware benchmarking system launched in July 2007.
Read the detailed report here.
Thanks to the VROOM! blog for the news.
Update: VMware published a second version of this benchmark, performed with same equipment and VMware ESX Server 3.5 instead of 3.0.2.
Numbers demonstrate a performance increase of 5%.
