Hi,
I'm planning to migrate my current server configuration:
AMD Athlon/X2
FreeBSD 62-Release
2 x 250GB HW RAID1 (all partitions RAIDed, incl. swap)
to a Xen/CentOS config:
AMD Athlon/X2
Dom0
CentOS 51
Xen 31
Dom1/1
FreeBSD 7
Dom1/2
CentOS 51
...
To "best preserve" RAID1 mirroring protections of OS, Data, etc
*AND*
optimize performance, how should I setup RAID for the "new"
configurations?
Should DOM0 be RAIDed?
Each DOM1, as well?
Should I continue to use HW RAID or switch to SW? A mix?
I understand I can do any/all ... choosing the "right" option is the
goal,
here.
Advice is appreciated.
Regards,
Bob Tompkins

You can do things like take LVM snapshots and have a clone of your system available for testing, for instance. In a recent Red Hat class that I took (RH436 - clustering and storage) we had a dom0 and several domU's - all of the domU's were actually snapshots of one "gold master" if you will, so that: 1) The amount of storage required is reduced 2) The ability to quickly rebuild one of the domU's to a "known-good" configuration. Let me know if you have any further question! -Jon
