To be fair -- and I used to work for Incyte, but as a programmer not a
sysadmin -- the sysadmin group was *much* bigger than that. Yes, Stu
started off the Linux clustering as a stealth project between him and
one other guy, whose name I'm ashamed I forget, but you have to
remember that a lot of the routine sysadmin stuff like DNS,
networking, authentication, account management, backups, and whatnot,
were out of their hands, handled by the [really quite large] central
system administration team. By the time they were up to a couple of
thousand nodes, there were definitely more of them running it. For a
start, IIRC there was no PXE provisioning, so it was one unfortunate
sysadmin's job to go round with a crash cart and a boot floppy
whenever a machine needed installing.
Incyte's systems team model was a central team which did all the core
infrastructure stuff, and then individual teams around the company had
dedicated embedded local sysadmins.
As always, my memory is subject to error, so if there are any ex-Palo-
Alto-Incyte sysadmins on the list, feel free to correct me...
