  1. HEAnet's relocation: Moving the Network and Services Brian Nisbet Network Operations Team BN227-RIPE

  2. Moving, Step-by-Step • Planning • Informing • Moving • Services • Schools • Office • Network • Cleaning-Up

  3. Planning • Move announced in early 2006, to be completed by July 2006. • Five month timeframe to move all equipment and personnel out of Brooklawn House. • Company-wide activity. • Aim to minimise cost and disruption to all users of the network and services.

  4. External Dependencies • Two Landlords. • Two groups of Building Contractors. • One firm of Furniture Movers. • Two providers of Co-lo services. • Four Telecommunications Companies. • A large number of very patient Clients.

  5. Spreading the Word • Clients had priority… • …but detailed information was slow to come. • Important dates were difficult to pin down from a long way off. • Some important events were at short notice due to availability of people/equipment. • Continued attempts to give as much warning and flexibility as possible.

  6. Services Move • HEAnet services supported by: • > 70 servers • 6 switches • 2 routers • Client co-location equipment requirements amount to 10 racks • Moved from Brooklawn House, Ballsbridge to ServeCentric, Blanchardstown • Move commenced planning in January 2006 • Tendering & ordering commenced in February 2006, completed in May 2006. • Move of equipment commenced mid May 2006, ended July 2006. • Project commenced and completed on schedule, within budget!

  7. Schools Services Move • Schools services moving from Brooklawn House to Servcentric. • Ten servers and some networking equipment. • And the email solution – more than forty pieces of equipment and over one kilometre of cat5! • No actual interruption to IP connectivity to individual schools.

  8. Exodus • 1st Floor, 5 George’s Dock, IFSC, Dublin 1. • New office was built from scratch, completely different requirements to old tenants. • Fewer offices, much bigger comms room. • Slow dismantling of Brooklawn House, prior to a one weekend move of furniture, fixtures and people.

  9. Exodus • Left work in Ballsbridge on Friday 21st July, went to work in the IFSC on Monday 24th July. • Office fully recabled and connected to the outside world (phone & data) by Sunday evening. • Full onsite NOC operations resumed by 09:00 on Monday morning. • Everything fully back to normal by Tuesday.

  10. Client/Network Moves (1) • Aim to remove the Brooklawn House (BH) PoP from the network and move all clients to other PoPs with minimal downtime. • Not everything was possible within the timeline. • All clients moved by 8th September, some remaining work to do due to provider capacity issues. Expected to be resolved by the end of 2006. • Longest outage – 48 hours. • Shortest outage – 1 minute.

  11. Client/Network Moves (2) • Stage 1: Create full access PoP in Citywest. • Stage 2: Set-up temporary HEA PoP. • Stage 3: Migrate BH clients to either Citywest or DCU on a per Telco/per technology basis. • Stage 4: Client moves out of temporary HEA PoP and final moves/reconnects of any remaining circuits.

  12. Stage 1 – Access PoP for Citywest • Temporary equipment taken from testlab and put back into production. • Freed-up production equipment moved to Citywest. • Circuit migration started from BH -> CWT.

  13. Step 2 – Temporary HEA PoP • Layer2 PoP only. • Space allocated by the HEA. • Two sets of fibre cuts and rack moves. • One evening’s work in both cases. • Unexpected fibre runs, both into and within BH. • PoP connected to the backbone via Bluenet circuit. • Not a viable long-term solution, planned to be in use until late 2006.

  14. Stage 3 – Client Migration • Citywest PoP • Technologies – SDH & Ethernet • Clients – DIAS, DIT, EPA, HEA, HETAC, HRB, ICHEC, IUA, ITB, ITnet, NCAD, NCI, NUIM, RCSI, TippInst, UCD. • DCU PoP • Technologies – Serial • Clients – CDVEC Crumlin, CDVEC Killester, CDVEC Liberties CDVEC Whitehall, NQAI, NUI, RIA. • Largest single move was six clients.

  15. Stage 4 – Final Steps • Current clients using the HEA PoP should be migrated out by end of 2006. • Notification that capacity issues have been solved and lead time of twenty days. • Chasing final circuit reconnects with Telcos. • Final audits of all network monitoring and documentation.
