My hosts are 3.5U4 with Dual-XEON, 32 Gb of ram and ISCSI (with 9K jumbo frame) links. My users experience slowdown if more than 40 VMs/hosts. On eavy load,with 40 users, i didn't saw more than 25Mo/s per LUN on the storage. It's not a storage limitation because it could give us more than 16 000 I/Os on SATA disks : http://ds45.blogspot.com/2009/06/la-bonne-surpise-du-matin.html Another information : ISCSI is enough ... (i had bench 120 Mo/s max by link) Hi Scott,

I stopped taking notes when I realized the numbers they were using were the same ones I saw back in VMworld and HP Tech Forum in 2007. Their numbers were junk and the info was dated. Bad session. Scott,
