is a bare metal approach?<br>

Your point is well taken about what I am doing and whether the approach is<br>
good or not. I need the box for two operating systems for computational<br>
work. I need to run a Windows flavor and I need to run Linux. There will<br>
be a performance hit, but based on what I have read, the hit is less for<br>
"bare metal" virtual approaches ... than it is for the situation where it<br>
runs within another platform.<br>

</div><div><div></div><div>In order to install a 64 bit version of an operating system in ESXi<br>
(probably ESX too but I know this for a fact with ESXi) the processors<br>
need to have virtualization capabilities built in, Intel refers to it<br>
as VT and AMD uses AMD-V IIRC. The x850 stuff from Dell pre-dates<br>
virtualization capabilities being embedded in processors, or at least<br>
they didn't ship any of it in the x850 series.<br>
<br>
If you wanted to run virtual 64 bit linux instances on there you<br>
should be able to do so with XenServer or one of the other Linux based<br>
virtualization solutions. If you're looking to use it as a compute<br>
resource I'm not sure that virtualization is the right track for you<br>
to b following but there you go.<br>
