My other concern is what happens when one drive goes down if we use
gmirror? Is it completelly transparent
and bad drive can be hot swapped while server is running and rebuild
started?
I am thinking now about gpt+gmirror (including boot and swap)

Yes. In fact, you can test this by

I am planning to use mirror configuration of two SATA 7200rpm 2TB disks.
I personally vote for gmirror in this case; I've used it a lot and found
it very good wrt to both performance and robustness.

Server Class drives buy you some improvement, but my recent experience with

There seems to be one more advantage to gmirror
If i understood correctly
gmirror label -v -b split -s 2048 data da0 da1 da2
will create a tripple mirror raid 1, that is
triple redundancy, which is hardly available on any hardware raid.
Am i correct here?
Also, does anyone know how to choose

GPT partitions should work, just limit it to one mirrored partition per
drive.
Please, clarify what you mean here.
If only one GPT partition on a drive is mirrored with another GPT partition
on another drive, head

Also, not being able to boot if first disk has some error in boot
section or just strangly dead is not an option too. However, i was
just thinking, if i use gmirror then bios does not know anything about
it. I may set both harddisk as boot disk, but if

The server is going to be a web server with many sites and with mysql

and cpu load is about 5% :) Everything is quick and responsive.

As far a gmirror is concerned, yes, drives can be removed and new drives

the hardware. I have not tried it with SATA drives, although I think

Hello!
I have to made a decision on choosing a dedicated server.
The problem i see is that while i can find very affordable and good
options they do not
provide hardware raid or even if they do it is not the best hardware for
freebsd.
The server base conf is 8core 32gb ram 2.8+ ghz.
So, maybe
