Primary Site Secondary Site Disaster Recovery Solution at DIAS : Based on IBM Shark Synchronous Data Mirroring (Peer to Peer Remote Copy - PPRC) Primary Site Secondary Site Alternate S/390 Server S/390 Server ESCON to ATM converters/bit racers S/390 user S/390 user IBM Enterprise Storage Server IBM Enterprise Storage Server 3490 Tape Units 3490 Tape Units ESCON links ATM links ESCON links ESS/PPRC Requirements : Alternate IBM Enterprise Storage Server with PPRC function ESCON to ATM converters/bit racers ATM telecommunication line Implementation time : 1 month

Benefits of the Disaster Recovery Solution to DIAS Insures data consistency and integrity with NO data loss Recovery Point objective : Latest Write Operation Recovery Time objective : < 30 minutes Solution is application/platforms/volumes independent Distance Independent (PPRC, PPRC/XD, XRC options) Seamless implementation Provides multi-platform support Fully scalable to handle growth Adaptable to change Simplified operations from a single point of control Independent of other IT projects / Application Transparent Based on expansion of existing infrastructure Protected previous IT investments (Shark, 3490 Tape) Leverages existing infrastructure / skills

Implementation Details Phased Approach PPRC Implementation at Primary Site (in-house) Thorough PPRC Function Test and Recovery : normal and abnormal termination, data/cpu switch, full recovery via restart Education : Hands-on training, skills transfer Performance impact analysis over ESCON : NO performance impact Infrastructure Preparation for Cross-Site Connectivity and Remote Mirroring ATM line activation (OTE) Network Converters Installation and Setup Tests with ATM and Converter

Implementation Details (cont.) PPRC Implementation Cross-Site (primary and secondary site) Thorough Disaster Recovery Solution Test over ATM Hands-on training, skill transfer Performance impact analysis over ATM : NO performance impact IBM Integrated Solution (A-to-Z solution) Solution Design Physical Planning at Alternate Site Analysis of Telecom Bandwidth & Line IT Infrastructure Communications Infrastructure Implementation Services Disaster Recovery Solution Testing Disaster Recovery Plan Education : Hands on training/skill transfer/formal education

The Implementation Experience Practically a 'plug and play' solution Carefully Planned Easy to Implement Fast implementation - Less than a month No performance overhead Easy to test Safe to test Easy to administer and maintain Easy to adopt to current running procedures Functionality as expected : Full recovery (restart) in a few minutes

Why we chose IBM Established IT Vendor in the Finance/Private Sector DIAS Technology Partner for over 10 Years Excellent Support Structure - IBM Greece 350 People Has Good Knowledge of DIAS IT Infrastructure/Needs Succesfuly Executed/partnered in numerous projects Studied DIAS specific BRS needs/objectives Leverages Worldwide Expertise drawn from Multiple BRS Engagements Performed Similar Engagements in Greece

Disaster Recovery Solution exceeded DIAS expectations Meets the Recovery Point Objective (RPO) and Recovery Time objective (RTO) of the business Ensures data consistency and integrity with no data loss Solution is application independent Provides multi-platform support Fully scalable to handle growth Simplifies operations from a single point of control Easy implementation Allows for thorough/regular testing

Future Enhancements Include cross-site tape extension / remote tape mirroring Implement Geographically Dispersed Parallel Sysplex (GDPS) that allows for Automatic Site Switch and Application Restart Integrate Unix/Wintel mission critical applications by consolidating (SAN) their data on the Shark and by expanding PPRC to mirror this data together with the mainframe data
