Technical Consideration in Disaster Recovery

2 And to think... those wimps at the power company use straps and cleats to get up this high!"

3 "Jack stands? Hah! Who needs 'em?"

4 I'm sure this guy still wonders why he got fired over this!

Business Continuance & Disaster Recovery are Different Business Continuance Focus is on avoiding disruption Deploy local and remote technology Disaster Recovery Focus is on recovering from disruption Deploy primarily remote technology Zero downtime can be achieved Close to zero downtime can be achieved Develop contingency plans Develop recovery plans Procedures to maintain business functions Procedures to recover business functions Train, Test, and Maintain Train, Test, and Maintain 8

Case 1 Use VPN to connect to DCs Pros: Bandwidth flexibility (1M to 1G) Easier upgrades Ethernet everywhere Ease of adding/removing nodes Any-to-any communication or specific point-to-point links Challenges No support for storage standards FC, ESCON, FICON No SLAs for latency and jitter Data rate typically limited to 1G Ethernet Access Ethernet Access Ethernet Access Metro (National) VPN [Layer 2 or Layer 3] Ethernet Access Ethernet Access 28

Case 2 Inter-DC Link Ring Options Pros: Greater bandwidth (up to 440G) Support all sort of interfaces: Ethernet, SONET, FC, FICON, etc. Protected service Fixed latency and no jitter Challenges Cost Only metro deployment Metro (National) VPN [Layer 2 or Layer 3] 29

Look at the full picture There is tendency to address business needs for BCDR one item at a time. The majority of the requests are intended to address an immediate need and not part of an overall design. The result is a less than optimal design. 31
