Migration Guide

Migration to the new INF high-speed server room network will happen in multiple stages.

Stage 1 - Move all storage host connections from old hs100 network to new high-speed network

The old hs100 “100GbE ring” network used for storage connections between INF servers and the DFSc Ceph service will no longer be available after mid-October. This is due to the existing fiber connections running across the DC-MC-M3 pedestrian bridge which will be demolished during the construction of the Mathematics 4 building.

* The new 10.1.244.0/23 server room storage network will be using a standard MTU of 1500 going forward. This is to prevent confusion with misconfigured hosts.

Since the new INF high-speed network and the old “100GbE ring” network use the same switches, users do not need to change any cabling. Every host with a layer 1 connection to the current “100GbE ring” network will be able to access the new high-speed storage network by adding the 3244 tagged network to their server network configuration.

Every host with a connection to the old “100GbE ring” storage networks should already have vlan 3244 tagged on their network interface. -dmerner

In the meantime, users can begin to create new IP addresses for their servers on the new high-speed server network and can add their tagged interfaces to their network configurations.

Hosts on the new high-speed storage network should use the storage.cs.uwaterloo.ca domain and should register their IP addresses using Inventory/IPAM.

The new vlan 3244 storage network is layer 2 only. It is not routed to campus (although that might change in the future).
