[Xen-users] Re: Memory and other settings for xen server, help needed....

[Robin van Leeuwen <rvl@xxxxxxxxxxxxxx>]

The MB is:

K8 Triton GA-K8NS-939:
nVidia nForce3 chipset
1x8speed AGP
5 pci slots
usb 2.0
Sata Raid controller : Nvidia nForce3 Ultra up to 150MB Sec,
    raid 0 and 1 , but only one disk installed.
No problems whatsoever with the sata, all brand new computers.

there is only one disk installed, since i have a HA failover cluster with
an extract replica machine standing on another side of the building.
