UCC Machines
The UCC runs a variety of different hardware. Not just your old Windows machines, or even the increasingly common GNU/Linux or Mac OS X machines. The UCC likes to run lots of other operating systems and architectures, which are sometimes uncommon or extinct out there in the Real World.
The list of machines is currently up to date in the list below.
If you want to know about our old machines, see the section Past Machines. To find out how we name our machines, see Nomenclature.

For the curious, here is a photo of our (ex) world class cooling system.
Server boot order
From time to time, the servers in the machine room go down and need to be restarted - to do so, there's a particular order that needs to be followed so things bounce back correctly.
Murasoi - Core routing / firewall - bring up first if networking is required.
Molmol - VMs will be hosted on this, we want them to be available when their hosts boot
Motsugo - Serves the user network home directories - needs to come up early as other things (eg. Mail) depend on it. Has an LDAP replica which avoids other complaints later.
Medico, Maltair and Loveday - host many virtual machines including Mussel and Samson
Mooneye - Internal UCC DNS and resolver
mailfish - mailfish must come up last - it relies on a number of other services (user home directories, routing etc.) Try and minimise the amount of time it's down - due to the UCC network design, it's the only MX for UCC. Most mailservers will requeue emails if they can't contact mooneye, but some will bounce after as little as a day.
All the other servers including Merlo. Especially check Dagon is on, since it lacks the ability to turn itself on after a power failure (it's the beige box in the left rack)
