RE: [Xen-users] Diskless xen

[Nathan Eisenberg <nathan@xxxxxxxxxxxxxxxx>]

My alternative implementation has been to use solid state storage - 
thumbdrives, CF cards with CF to SATA/IDE adapters, or disk-on-module SATA or 
IDE devices.

Any of these will do the trick and leave you with enough space on the module 
for log files, etc.  It's not quite diskless, but it's very low power and heat, 
and significantly less prone to failure than hard disks.

Also, I strongly recommend you consider getting something like this for 
connectivity to the iSCSI SAN:

Bond those 4 into a dedicated 4gbit interface to the SAN.  My configuration 
actually has two of these in each server - one for SAN, and one for migration 
traffic (live migration goes FAST over 4gbit :) ).

Hope this helps a bit.

Subject: [Xen-users] Diskless xen

Hello,

I want to implement a diskless xen hypervisor. The way I suppose it will work 
is xen booted over pxe and 
getting iscsi san storage to store vm images.

Is solution like that usable ?
