Ok, cool. If you’re just paying for the rack space and power, make sure you know what the rates are for going over power allotment (and bandwidth if it includes burst, some ISPs might still charge extra of you burst above the bandwidth you’re paying for). Confirm if you’ll have access to 120v or 240v or both. What power cables you’ll need for your PDU or servers if they’re providing the PDU.
This really depends on the services you’re paying for from the colo.
Assuming they offer internet services, you can probably chooses between a static or dynamic IP for your WAN IP. For your internal network, you would be responsible for DHCP or static assignment.
You’ll also need a security device like a firewall or router that can perform NAT for your internal addresses.
This info is assuming a lot, I’m not sure if you’re paying for a service that might include the WAN networking component, or if you’re just paying for power and real estate.
Happy to help with any more info if you have specific questions.
Also, you should be able to physically access your gear yourself so you’re not paying for smart hands. I would ask the colo of their access hours are anything other than 24/7.
Have an old Dell Optiplex with a E3-1200 Xenon running esxi with 32GB RAM and an Nvidia k620.
Just got a smoking deal on a DS1819+ that I’ll be loading with 12TB drives.
