DWDM Solution Technical Requirements ==================================== High Level Diagram SITE A / DC-A SITE B / DC-B +---------------------+ +---------------------+ | Chassis #1 |==============================| Chassis #1 | | | Provider-A ACTIVE | | | |------------------------------| | | | Provider-B STANDBY | | +---------------------+ +---------------------+ +---------------------+ +---------------------+ | Chassis #2 |==============================| Chassis #2 | | | Provider-C ACTIVE | | | |..............................| | | | Provider-D STANDBY | | +---------------------+ +---------------------+ ======== Active / primary path -------- Standby path for Chassis #1 ........ Standby path for Chassis #2 Distance between SITE A / DC-A and SITE B / DC-B is 30KM. Protection Logic ---------------- • Provider-A is the normal working path for both chassis • Chassis #1 fails over from Provider-A to Provider-B • Chassis #2 fails over from Provider-C to Provider-D • Each chassis has only one standby provider • Switchover occurs on path failure or degradation • Target switching time of the path switchover <50ms Technical Requirements ---------------------- • Minimum 2x SAN 32Gb/s ports and 2x 25G network ports per chassis (transceivers should be included). Ability to add additional client ports 2x SAN 32Gb/s ports and 2x 25G network ports. • Each Chassis should support two independent links for redundancy • Solution should support data encryption • Each chassis should have redundant power supply • Solution should support automatic protection switching without manual intervention • Solution should support reliable operation between two data centers separated by approximately 30 km of fiber distance without any intermediate hardware • Each chassis should support minimum aggregate throughput 200Gb/s. Ability to increase throughput capacity without requiring hardware upgrades will be considered advantageous. • Solution should have comprehensive monitoring functionality 24/7 vendor support. Customer should have ability to independently open support tickets.
