Booming demand for accessibility and performance in Multi-Tenant Data Centers (MTDCs) is driving demand for advanced Data Center Interconnect (DCI) technologies. As the migration to cloud services continues to pick up steam, MTDCs are growing in popularity as a way to reduce capital costs required by traditional data center operations. However, within MTDCs today, difficulties delivering dedicated bandwidth to current customers—along with long lead times for network orders, static bandwidth, and bandwidth contention issues—are growing challenges. This paper explores these challenges and describes Ciena’s expertise in planning, designing, and deploying networks in support of MTDC operations.
