Situation as of 2 Q 2006 • UCSD had almost no DR plan in Situation as of 2 Q 2006 • UCSD had almost no DR plan in place • UCOP used IBM contract in Colorado – Cost $200 k / yr + $600 k/month if ever used – Had insufficient gear and network reserved, cautiously estimate would be > 50% more cost if updated appropriately – 40 hrs of testing / year limit, difficult to schedule – RPO (Recovery Point Objective) <= 7 days – RTO (Recovery Time Objective) <= 3 days – Required UCOP personnel to activate and operate – Past testing indicated decent mainframe recovery plan in place, limited distributed system capability RIDING THE WAVES OF INNOVATION • cenic 09. cenic. org 3

DR Concept • UCOP required shorter RPO & RTO • Found trusted partner (UCSD) DR Concept • UCOP required shorter RPO & RTO • Found trusted partner (UCSD) – Willingness to be “married” • Technical choices • Change management – ongoing • One “team” • Common principles • Use the WAN “stupid” RIDING THE WAVES OF INNOVATION • cenic 09. cenic. org 4

Keys to Approach – Buy enough storage, synchronize data in real or near real Keys to Approach – Buy enough storage, synchronize data in real or near real time, avoid loading data during an actual DR event – Mainframe – CBU option and buy memory – Other servers – buy sufficient gear to have capacity available to run at either location without having to repurpose servers during event – Must be able to test and retest – DR is not STATIC! The decision to do it! RIDING THE WAVES OF INNOVATION • cenic 09. cenic. org 5

Advantages of this Approach • Costs for UCOP are comparable to old DR plan Advantages of this Approach • Costs for UCOP are comparable to old DR plan • Costs for UCSD are <50% of a vendor solution • Capability is dramatically improved – RTO and RPO < 1 day (and will be far less) – Can test as often as needed (we need it!) – Equipment is there and operational – More services can be “easily” added (and have!) after the initial investment and can optimize over time – UC personnel “on other side” will assist in case of disaster, long term goal is to recover without any personnel from down location immediately available RIDING THE WAVES OF INNOVATION • cenic 09. cenic. org 6

Initial Critical Success Factors • UCOP assigned. 5 FTE staff dedicated to drive effort Initial Critical Success Factors • UCOP assigned. 5 FTE staff dedicated to drive effort • One Team – UCOP and UCSD • Agree to basic principles, including $$$ • Fight scope creep • Engage procurement personnel • Communicate, communicate • Test, Test • The WAN!

Services being Considered – UCOP California Institute for Energy and Environment – UCLA Med Services being Considered – UCOP California Institute for Energy and Environment – UCLA Med PPRC And what’s next? Broader discussions are now occurring, not just w/ UCOP, but between more and more UC players – nice “halo” effect with many leveraging the WAN!

Technical Details • SD & OP (and SB & SDMC) purchased comparable HW • Technical Details • SD & OP (and SB & SDMC) purchased comparable HW • IBM SAN & Cisco SAN switches, supports global mirroring (PPRC – Peer to Peer remote copy) • Mainframe – memory upgrade and CBU option – must have sufficient capacity on both sides to support total load • Worked through CENIC and local network teams to set up appropriate links for PPRC to ensure throughput • Wrote (and are writing) special monitoring tools • Setup remote tape capabilities so we don’t have to use outside vendor for offsite storage on tape copies • You need to remember that this hardware needs to be in normal refresh cycle just like hardware on your primary floor RIDING THE WAVES OF INNOVATION • cenic 09. cenic. org 18

Network concerns • Frame size • For low traffic, default end to end of Network concerns • Frame size • For low traffic, default end to end of 1500 bytes – works fine • OP/SD (more traffic) had to move into “jumbo frames” – 2300 bytes seems to work • On HPR today, need to move to DC • @ OP – likely upgrade to 10 Gb, at 1 Gb now • Must refine SLA’s & due diligence • Acceptable catch up (RPO issue) • Better understanding of traffic RIDING THE WAVES OF INNOVATION • cenic 09. cenic. org 19

Implications due to “Success” • OP WAN capacity connection upgrade • Change management is Implications due to “Success” • OP WAN capacity connection upgrade • Change management is a lot more complicated • Some technical “lock in” • Insufficient documentation and test plans – even now. • Better monitoring tools required • Org processes can be stressed RIDING THE WAVES OF INNOVATION • cenic 09. cenic. org 21
