I've been doing SysAdm and running several =large= sites (like the one that runs Hilton Hotels reservations systems) for something like 15 years now <ALT=greybeard.jpg>, but I'm about to move a datacenter into a CoLo site for the first time. Up until now, I've always owned the datacenter. We're still thinking about What All That Means. And I'm frustrated by the access I'll no longer have. But one thing I intend to do is cross-wire the serial ports of each redundant machine pairs we install and run serial consoles on them. That is, the pair of machines that are performing firewall duty (and database duty, and web server duty, and Java servlet container duty...) will be able to see each other's consoles on their serial ports. That way, I should be able to re-boot (and debug) the offline guy via the online machine. Elsewise, I'd put in a Shiva/TrailBlazer/<mumble> terminal server to see =all= the serial ports. But the above method eliminates a SPOF (single-point-of-failure) and saves me one unit of rack space. -crl -- Chad R.
