Justin Newton (Erols, AboveNet, ...) has a short artical on
DataCenters in WebTechniques, where the issue was on that topic:

Too vague; it all depends on what you want to do. Build a regional
provider, or run a mom-n-pop local ISP.
I've supported a couple of the latter-sized sites, 1-2K users. One
runs out of a converted closet, the other runs out of an unused
office. For us the most important and beneficial features were good
cooling, a couple of racks, and locks on the doors; a handful of
servers do the work and they're commodities. Getting rid of analog
modems and all that cable mess for digital access boxes (e.g.,
Livingston Portmaster 3 or Ascent Max series) helps loads. Think about
backups and disaster recovery.
Tolerance? I don't understand.
Security? Lots of things you can do here. Turn off everything you
don't absolutely need. Practice security in depth. Monitor stuff.
Balance? Like web load balancing? fault-tolerance? Check Foundry,
CoyotePoint, etc. This may not be an important issue until you get
large.
Admin? Couple it with security. Hire competent people so they can
educate more junior folks.
Monitoring? Part of security, and part of performance analysis. Lots
of security monitoring tools. MRTG is themost popular software I know
of for monitoring stuff like WAN links, ethernet load, or anything you
can query with SNMP (I monitor our number of modems in use to see when
we should buy more).
You should probably ask over on inet-access; that's what they do.
