Lenovo ThinkSystem DB720S Gen7 FC SAN Switch Specification and Datasheet
Brand Name: Lenovo
Product Name: Lenovo ThinkSystem DB720S Gen7 FC SAN Switch
Machine type:7D5J
System Architecture:
Fibre Channel Ports:
Switch mode (default): Minimum of 24 ports and maximum of 64 ports. Ports are enabled in increments of 8 ports up to 64 ports via Ports on Demand (PoD) licenses; E_Ports, F_Ports, M_Ports, D_Ports, and EX_Ports.
Up to 48 autosensing ports that support 32Gb or 64Gb SFP+ transceivers
Up to 8 double density (DD) ports that support either SFP+ (32Gb or 64Gb) transceivers for a single connection, or SFP-DD transceivers that each support two 64G connections, thus providing an additional 16 ports at 64Gb.
Access Gateway default port mapping: 56x SFP+ F_Ports, 8x SFP+ N_Ports.
The SFP+ ports are capable of auto-negotiating to 8, 16, 32, or 64Gb speeds depending on the SFP+ model and the minimum supported speed of the optical transceiver at the other end of the link.
Scalability:Full-fabric architecture with a maximum of 239 switches
Certified maximum:4K active nodes; 56 switches, 19 hops in Brocade Fabric OS® fabrics
Performance:
Non-blocking architecture with wire-speed forwarding of traffic:
8GFC: 8.5 Gb/sec line speed, full duplex
10GFC: 10.53Gb/s line speed, full duplex; 10Gb/s optionally programmable to fixed port speed.
16GFC: 14.025 Gb/sec line speed, full duplex
32GFC: 28.05 Gb/sec line speed, full duplex
64GFC: 57.8 Gb/sec line speed, full duplex
Traffic load balancing:
Frame-based ISL Trunking load balances supports up to eight SFP+ ports per ISL trunk; up to 512Gb/s per ISL trunk when using 64Gb/s optics
Dynamic Path Selection (DPS) provides exchange-based load balancing across all available ISLs.
Aggregate bandwidth:4.096 Tb/s
Maximum fabric latency: Latency for locally switched ports is 460 ns (including FEC).
Maximum frame size:2112-byte payload
Frame buffers: 24K per switching ASIC
Classes of service:Class 2, Class 3, Class F (inter-switch frames)
Port types:
D_Port (ClearLink Diagnostic Port), E_Port, EX_Port, F_Port, M_Port
Optional port-type control
Brocade Access Gateway mode: F_Port and NPIV-enabled N_Port
Data traffic types:Fabric switches supporting unicast
Media types:
