First time using Xen, I come from a vmware world but would like to expose myself to some Xen technology. With that said, I have a spare server (Dual proc, 8G of RAM w/ 2 x 500G sata drives). Stupid thing doesn't have HW raid so I'm forced to use software based. With that said, is it worth using software? I've read that software-based RAID could be slow, and I'm fine with syncing my data elsewhere for backup purposes.

Sounds like your 'playing'/testing - software RAID will be fine for that, some here are more than happy to use in production too. Obviously if you're doing a lot of writes it'll be slower overall as it'll have to write everything twice but iirc reads are pretty comparable.

Either way just get on with learning and when you look to go into production then look at performance :)

Came across another thread that says the dom0 can't sit on a RAID1? Is that true? – luckytaxi Jun 23 '11 at 14:22
