Network outage – 21 Nov 2010

Posted by on November 10th, 2010 · Kensington campus, network, Scheduled maintenance

To complete the upgrade of the UNSW core network, we need to complete an upgrade to the distribution or user network similar to the recently completed Data Centre upgrades. This will replace the existing Cisco Catalyst 6500 router with the Cisco Nexus 7000 router. The key benefits from this upgrade are:

  • providing significantly more backbone bandwidth including upgrade from 20 Gig to 40 Gig just by completing the upgrade
  • capacity to connect 10Gig connection to buildings
  • 15Tbps backplane capability
  • Maintaining currency of technology

This upgrade though won’t be as tight in terms of outages. While we were able to get it down for the data centre environment, there was far too much pressure and risk with this approach. This is a more moderate approach but focuses on a balanced approach to minimise interruption. The changes will also take longer with 54 buildings to have physical and logical environments moved. It is expected that during the upgrades each user will experience:

  • 1 x 15 minute outage while the physical connection of the building is migrated (layer 1)
  • 1 x 5 minute outage (campus wide) for spanning tree (layer 2) migration
  • 1 x 10 minute outage while the routing is moved (vlan outage as opposed to building – layer 3)

I am happy to run meetings again to explain, or if you have enough knowledge, requesting if you can please engage within your portfolio re seeking approval. We have picked Sunday 21st November 2010 as this is after exams, after the Saturday pay run and appears to have no key University dates.
