ThinkSystem DB720S system specifications.

Component	Specification
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	64Gb/s: Brocade Secure hot-pluggable SFP-DD, SN connector; 64Gb/s SWL 64Gb/s: Brocade Secure hot-pluggable SFP+, LC connector; 64Gb/s SWL, LWL 10 km, ELWL 25 km 32Gb/s: Brocade Secure hot-pluggable SFP+, LC connector; 32Gb/s SWL, LWL 10 km, ELWL 25 km 10Gb/s: Brocade Secure hot-pluggable SFP+, LC connector; 10Gb/s SWL, LWL 10 km Fibre Channel distance is subject to fiber-optic cable and port speed.
USB port	One standard USB port for firmware download, support save, and configuration upload or download.
Fabric services	BB Credit Recovery; Brocade Advanced Zoning (Default Zoning, Port/WWN Zoning, Peer Zoning); Congestion Signaling; Dynamic Path Selection (DPS); Extended Fabrics; Fabric Performance Impact Notification (FPIN); Fabric Vision; FDMI; FICON CUP; Flow Vision; F_Port Trunking; FSPF; Integrated Routing; ISL Trunking; Management Server; NPIV; NTP v3; Port Decommission/Fencing; QoS; Registered State Change Notification (RSCN); Name Server; Slow Drain Device Quarantine (SDDQ); Target-Driven Zoning; Traffic Optimizer; Virtual Fabrics (Logical Switch, Logical Fabric); VMID+ and AppServer. Access Gateway mode : Some fabric services do not apply or are unavailable in Access Gateway mode
Extension	Fibre Channel, in-flight compression (Brocade LZO) and encryption (ES-GCM-256 encryption on FC ISLs, E_Port); integrated optional 10Gb/s Fibre Channel for DWDM MAN connectivity
Power supplies	Dual, hot-swappable redundant power supplies (80 PLUS Gold) with integrated system cooling fans (3 built into each power supply), N+N cooling redundancy
