Yes, that's a production system. However when some disk fails, I don't care. This system is somewhat overmirrored. There are three (maybe even more) levels of mirroring. Everything is placed on Symetrix EMC storage system. There are:

1) "Classic mirroring" - Oracle database on mirrored disk sets
2) Internal fail-over mirroring by EMC
3) Storage system mirroring - we have two of these EMCs in

geographical cluster solution (two placements with few kilometres distance between them).

So I think that we would have no problem, even if some disk would die.

can call it an overture to bankruptcy) on that server. I'm still using
this email to prevent SPAM. Maybe one day I will change it and have a
proper mail even for news, but right now I can be reached by this
