ESXi 4 Update 2 Release Notes

Noted in the release is the official support for AMD’s IOMMU in Opteron 6100 and 4100 processors – available in 1P, 2P and 4P configurations. This finally closes the (functional) gap between AMD Opteron and Intel’s Nehalem line-up. Likewise, FT support for many new Intel processors has been added. Also, the addition of NFS performance counters in ESXTop will make storage troubleshooting a bit easier. Grab you applicable update at VMware’s download site now (SnS required.)
