I'm just spec'ing a G5 Xserve for my company and had planned to mirror the System volume using Apple's Software RAID.
I discussed this idea with my supplier (a relaible authorised dealer) and he said that his technical department had found that trying this resulted in continual system crashes... Obviously not very satisfying and I have to say I can't see why this should be.
We will test this ourselves once we purchase the kit, but I wondered if anyone here has any experience of this and if they also have had problems?
