Lenovo ThinkSystem DB720S Gen7 FC SAN Switch

The Lenovo ThinkSystem DB720S Gen7 FC SAN Switch is a purpose-built backbone for modern data centers, engineered to scale storage networks as data growth accelerates. With industry-leading port density and a bold commitment to high-speed Fibre Channel performance, this switch is designed to simplify SAN fabrics, reduce latency, and empower data-intensive workloads. The Gen7 model raises the bar for reliability and efficiency, delivering a 50% latency reduction over the previous generation while maintaining robust compatibility with existing storage arrays, virtualization platforms, and disaster-recovery architectures. Built to support consolidation, virtualized environments, and NVMe-based storage ecosystems, the DB720S Gen7 provides a solid foundation for organizations pursuing faster data access, streamlined management, and cost-effective growth across multi-site data centers.

• 64Gbps per-port performance with ultra-low-latency fabric: Each Fibre Channel port delivers 64 gigabits per second of throughput, enabling high-bandwidth storage traffic, rapid backup windows, and smooth data replication for mission-critical workloads. The Gen7 architecture optimizes I/O paths and reduces end-to-end latency, helping applications reach peak performance even under heavy I/O pressure.
• High port density for dense, scalable SAN fabrics: Designed to maximize rack space without compromising throughput, the DB720S Gen7 combines a compact 2U form factor with a dense port lineup. This enables enterprises to connect more servers and storage arrays in fewer devices, simplifying cabling, reducing footprint, and delivering scalable storage networks in growing data centers.
• Redundant power and resilient design: The switch supports hot-swappable, redundant power supplies and dual-management paths to minimize downtime. With built-in fault tolerance and streamlined failover capabilities, organizations experience higher availability, reduced maintenance windows, and improved service continuity for critical storage services.
• Integrated management and automation-ready control: Lenovo XClarity and REST API support provide centralized, intuitive fabric management. Automate provisioning, monitoring, and policy-based configurations across your SAN, enabling faster deployments, consistent configurations, and easier lifecycle management for administrators and IT teams.
• Advanced features for security, virtualization, and NVMe-FC readiness: The DB720S Gen7 supports zoning, NPIV, and NVMe over Fibre Channel (NVMe-FC) to facilitate modern storage architectures. These capabilities enable secure multi-tenant access, flexible host connectivity, and high-performance paths for NVMe-based storage arrays—delivering the benefits of NVMe with the reliability and simplicity of Fibre Channel fabrics.
