"...the biggest limitation with ESX Server 3i and its
big brother, ESX 3.5 is that due to VMWare’s “closed
kimono” stance on software development, the storage drivers
are way behind in terms of hardware support when compared with
competitive solutions from Microsoft, Citrix and the various Linux
distributions/vendors. There isn’t a single system, whether
it be a PC or an entry-level server which use embedded SATA2 RAID
chipsets that will work with ESX 3i or ESX 3.5 out of the box. If
you boot ESX 3i on any of these systems, you’ll be presented
with a message that no suitable storage device has been
found."
