(4) System Reliability (A) System components of servers, storage and network devices must have appropriate redundant configurations to avoid SPOF. (B) The service level of this system will be the best effort level (Maintenance time is expected and system downtime might occur in case of a critical failure.) (C) In order to verify the results of processes, logs will be maintained. (D) A remote disaster recovery (DR) site will be set up in the server room of the CBM Nay Pyi Taw Head Office. See also (7). (E) Data backups will be stored on tape in preparation for data corruption and for system audits. (5) System Scalability/Flexibility (A) Appropriate server resource allocations will be possible using virtualized servers, and physical servers can be added for extra workloads. (B) Storage resources can be extended by adding HDDs and drawer units.24 (6) System Neutrality (A) Regarding system equipment, network devices, UPS and racks, which can be procured in Myanmar, will be preferentially adopted. Especially, equipment requiring additional procurement and expendable items, such as printer toner, must be procured at an appropriate price in Myanmar. (B) As far as possible, the system should not depend on specific manufacturers and products. (7) Business Continuity (A) A remote disaster recovery (DR) site will be set up in the server room of the CBM 24 The drawer unit is an equipment for install HDDs for expanding storage resources, and is connected with the storage controller unit. 85
