Colocation

Like the years before we are, once more, providing a colocation at GPN22.

In case of problems, find us at the NOC desk or call DECT 6620.

Location

This year it is in the Pförtnerhäuschen, which is the locked space that housed the yolocolo back at GPN19.

This location has limited cooling and power budget and cannot accommodate for power hungry devices.

We will try to provide the colocation as best effort. Normal GPN-Network has priority.

You should be able to use the colocation starting Thursday afternoon.

We close the colocation on Sunday (Timestamp will be added soon), please fetch your devices before then!

Basic Rules and policy

be excellent to each other!
we reserve the right to disconnect your server
access is only allowed in the presence of NOC staff
devices must be labeled with an email-address and a DECT-Number (if you have one). Any other information is voluntary
prepare your server before placing it in colocation. We can only grant access to the colocation in exceptional cases outside of placing and picking up

How to connect

bring you own SFP(+) transceivers and cables (we do not have any cables or transceivers for the colocation)
add a label with your email(must) / dect(should) on any devices in the colocation
talk to noc
- you will receive a clothespin with an ip-address (v4 and v6)
- noc will provide access to the colocation
- noc will verify the label with the dect-number on the server
- exchange PSK with noc (you will need your dect or PSK to retrieve your server)

How to retrieve your server

shutdown your server remotely (minimize time spent in colocation)
talk to noc
- is your server powered off?
- noc will provide access to the colocation
- verify yourself with DECT or PSK
- collect your server

Pixelflut

Pixelflut is not hosted by NOC. Some people create a completely separated and isolated network with no access to the GPN-Network.

You will find a dedicated switch for Pixelflut on the YoloColo. Having two network-cards is recommended. You can find more information here: GPN22:Pixelflut

Connection/Uplink

YoloColo is connected with 100G to our core.

Your server can connect with 10G to our YoloColo-Switch.

Addressing

IP addressing is static only. We use "Laundry Clip DHCP": Get your laundry clip at the NOC Desk and attach it to your network cable. Please bring back the laundry clips after the event.

Configure your network interfaces like this (X is your laundry clip number):

IPv4

Address: (will be added soon)
