Description
Product overview
The Lenovo ThinkSystem DB820S Gen 8 FC SAN Switch, with its unmatched 128Gbps performance and industry-leading port density, provides a building block that supports data growth, demanding workloads, and data-center consolidation. Its advanced Brocade Gen 8 technology combines quantum-safe security, and AI-powered autonomy, to enable the most reliable and efficient way to protect and deliver critical information.
Key capabilities
- Machine type: 7DMA
- Enclosure: Back-to-front airflow; non-port-side intake (NPI); 1U; Front-to-back airflow; non-port-side exhaust (NPE); 1U
- Fibre Channel Ports: Switch mode (default): 56 128G SFP+ ports, each supporting E_Ports, F_Ports, N_Ports, M_Ports, D_Ports, and EX_Ports; 24-port base configuration; additional ports are enabled with four 8-port SFP+ PODs (Ports on Demand), scaling the switch from 24 ports to 56 ports; Brocade Access Gateway default port mapping: 56 F_Ports, 8 N_Ports
- Scalability: Full-fabric architecture with a maximum of 239 switches
- Certified maximum: 4K active nodes; 56 switches, 19 hops in Brocade Fabric OS® fabrics
