For security you can look at centos with selinux and opensuse with novell apparmor but you can also do this with Ubuntu or any other distro. LVM is now standard in LInux  there is no problem with dealing with zoning SAN and mounting LUNs with your server; you can also zone two-gigabit cards per server and avoid single point of failure and also heartbeat for high availability cluster.

Actually the most significant problem that you will encounter are not about security or SPOF. If you will be using your servers for databases make sure that you tuned your system to the database requirement. DBAs ang pinkamakulit to deal with; they refuse all reasons  that they are at fault for improperly tuning their databases  required for the system.

I want to set up a mission critical (i.e. a lot of critical
information is being shuttled to and from the server/system) solution
on Linux, and I have a choice on the distribution.

I don't want to start a distro war (again), but I would like to know
how many people in the list will actually trust Ubuntu on the Server
as compared to something like CentOS/RHEL, SuSE, or Debian ?

I have the following criteria for evaluation:

* Vulnerability Assessment
* Security Update Frequency and Relevance
* Robustness (no unstable/untested software installed)
* Stability (predictable and non-erratic behavior)
* Unbloatedness (contains only essential components in base system)
* Scalability with Hardware (should support hardware for scalability
(SAN, RAID, Gigabit Ethernet Channel Bonding, Hot Swappable Drives,
Failover Power Systems Support, Clustering (HPC/HA) ) ).

So far, for all these items Ubuntu still doesn't rank as well as
CentOS/RHEL, SuSE, and even Debian.

I might be alone in this view, but can someone please enlighten me
about how well Ubuntu is doing on the server side?
