I think you guys know better than me, but I'll try to summarize here:
* rack space and power for 3 x 1U servers.
* 4 public IP addresses
* If possible. global IPv6 addresses should be routed as well
(otherwise we'll use 6to4)
* Isolated gigabit LAN to interconnect the machines.
(this could be done with port management in the switch or
with a small dedicated switch).
* Contacts of on-site sysadmins who could assist us in case of
emergencies (best-effort, no obligation).
* Provide physical access to Sugar Labs sysadmins for initial
setup and future maintenance. The initial setup will be carried
on by Stefan "dogi" Unterhauser.
* Bandwidth usage is projected to peak at 15-20Mbit/s during
morning hours (GMT+3).
* We don't need space for backups as these servers won't store
valuable data and are easy to reconstruct from scratch
If RIT agrees to host it, at a later time we might add one more 1U or 2U
server running our primary websites: wiki.sugarlabs.org,
planet.sugarlabs.org, lists.sugarlabs.org and others. It's expected to
use less bandwidth than ASLO, though.
