** I know Fake RAID is a no-no
Not if you considered using it, ever. It's not a "slightly not recommended" kind of thing, it's totally and absolutely out of the question for any workload where you want any kind of reliability. You would never have RAID 1 on FakeRAID, it makes no sense at all. All the cost of redundancy and then destroying the reliability with FakeRAID. And Intel FakeRAID is worse than most, too!

Though we are talking about software RAID...what to do?
If you don't have hardware RAID, then you use enterprise software RAID that is part of XenServer. There shouldn't be anything to ponder. There are just the two options.

How does that look?
a single boot drive that has XS on it? and that loads a driver that create the software RAID on the remaining drives in the system? Or can you include the boot drive? -

MD supports boot RAID. This isn't Windows
Is this the preferred method vs XS booting off SATA DOM, USB, HDD etc.?

SATA DOM is probably the way to go. Built just for this.

How about redundancy for the SATA DOM?
I remember there was a previous thread about a USB stick, but that involved physically removing the stick & making a copy.
Whatever happened to having a "live" 2nd copy? -

Whatever happened to having a "live" 2nd copy?Assuming the system has ports and space for 2 DOM, then you just RAID them with MD as Scott mentioned earlier.

SuperMicro recommends no redundancy.

Yup, if there are two they will handle software RAID just like any other hard drive.

Whatever happened to having a "live" 2nd copy?You can still make a copy of a SATA DOM to a USB stick.

SuperMicro recommends no redundancy.
Wonder why?

Can you automate this ?

Not realistically, no.
