if two are dead then you will have lost 50% of your data - and most likely you wont be able to boot.
your best bet is to try and fix one of the drives - it may be a dead controller board and the actual disk is ok

Did both of the failed disks go out at the same time?  If so check your controller, backplane, and cable connections.  Also try reseating the disks if they are hotplug.  You need 2 of the 3 to work to boot.

Unfortunately with 2 disks failing at the same time you won't be able to use the array.

If i put them in an identical server, they still show as failed.They did not go out at the sametime but just days apart.  Is it possible at this point to get another hd and rebuild?

Unfortunately not.  If only 1 was failed then you can rebuild, but if 2 of 3 are gone then the data is lost.

No, you would have had to rebuild after the first drive failed.

Once the second drive went the parity was destroyed making it impossible to recover anything from the failed array.

Your only option at this point is a professional data recovery service and they charge thousands of dollars.

You said that the two failed disks did not fail at the same time.  If you don't know which it is, then you either take a 50/50 chance of guessing the right disk, or call data recovery.  If you need to call data recovery, do that first.  If you do know which disk failed first, then ignore it.  Force Online the other disk (the last disk to fail) ... do this in CTRL-M, Objects, Physical Disks.  In order for this to work, the disk that did not fail must be online, and the last disk to fail must show as Failed.
