The Lenovo ThinkSystem DB400 Series Fibre Channel Switch is a purpose-built Gen7 64Gb FC fabric platform designed to serve as the high-performance backbone of modern all-flash and all-NVMe storage area networks. Built on Broadcom's Gen7 ASIC architecture, the DB400 Series delivers per-port bandwidth of 64Gbps with aggregate non-blocking throughput engineered to eliminate fabric congestion in latency-sensitive workloads. The switch supports NVMe over Fibre Channel (NVMe-oF) natively, enabling direct-attach NVMe storage arrays and NVMe-oF initiators to communicate across the fabric with sub-microsecond latencies that are unachievable with legacy SCSI-based FC implementations. Advanced ISL trunking and Dynamic Path Selection ensure maximum bandwidth utilization across inter-switch links without manual administrator intervention.
The DB400 Series integrates Lenovo's enterprise SAN management toolchain, including compatibility with ThinkSystem Director and Brocade SAN Health analytics for proactive fabric diagnostics, performance monitoring, and automated anomaly detection. The platform supports advanced fabric services including Fabric Vision technology with IO Insight, allowing administrators to identify slow-drain devices, monitor buffer credit health, and perform non-disruptive diagnostics at wire speed. Zoning, RBAC-based access control, and FIPS 140-2 compliant management plane security are all standard, making the DB400 Series suitable for regulated industries including healthcare, financial services, and government.
Launched in Q3 2025, the DB400 Series addresses the growing demand for Gen7 FC fabrics driven by the proliferation of NVMe-based primary storage arrays from vendors such as NetApp, Pure Storage, IBM, and Lenovo's own ThinkSystem DE and DM series. The switch is available in fixed-port and modular director-class configurations, enabling deployment from edge data center SAN islands to core enterprise fabric architectures requiring hundreds of ports with full redundancy, non-disruptive firmware upgrades, and hot-swap field-replaceable units including power supplies and cooling modules.
