If you want any support, then it has to be one of the Red Hat Enterprise
Linux versions, or a non-Red Hat version (e.g. SuSe).

That is not true. 8/9 add a lot of server features like LVM, SW Raid support
at install time, experimental ACL support, better kernel VM and kernel utils
(e.g. irqbalance), Native Posix Threading in the kernel, newer mailman
software, a different ftp server, apache 2.x and newer php, devlabel support,
etc. Plus some security upgrades to sendmail (runs as two processes instead
of one), ssh, iptables is the default instead of ipchains, etc.
It is not just desktop stuff, there is a lot of server updates in there.

Yes, it is sufficient. But I would run something newer. For example, I
waited for years for LVM so I can do snapshots. I've upgraded all my
servers so I could use LVM.

If you need something that is only available or supported on 7.x, then
I would recommend 7.x. RHEL 2.x is based on RH 7.x, so it would probably
work also. RHEL 3.x is based on RH 9, so beware of that.

Dell OM should run on any Dell Supported version. I would stay clear of
RH 7.0 as it was a terrible release with lots of strange quirks (2.4 kernel
ready but running the 2.2 kernel, shipped with lots of security bugs, out
of RH support, etc).

Only slightly. You should be able to run OM on any release.
