Technical data

‐ Policy based monitoring monitors FCIP connectivity and WAN anomalies using multi-layer
metrics.
‐ Flow monitoring reports IOPS and data rate of individual I/O flows of inter-DC replication
and tape backup operations.
‐ Flow generator generates FC frames for a defined flow with default or custom size and
pattern and sent across FCIP tunnel to help validate end to end network setup and
configuration.
• Brocade Fabric OS delivers distributed intelligence throughout the network and enables a wide
range of value-added applications.
Brocade 7840 hardware features
The Brocade 7840 provides the following hardware features:
• 24 Fibre Channel ports with link speeds of 2, 4, 8, and 16 Gbps, compatible with short wavelength
(SWL), long wavelength (LWL) and extended long wavelength (ELWL) SFP+ transceivers
• Rack-mountable 2U chassis
• Sixteen 1 GbE/10 GbE ports, compatible with copper, ultra short reach (USR), short reach (SR) and
long reach (LR) SFP/SFP+ transceivers
• Two 40 GbE ports, compatible with short reach (SR) and long reach (LR) QSFP transceivers
• One RJ-45 Ethernet management port with 10/100/1000 Mbps autonegotiating capability
• One USB port that provides storage for firmware updates, output of the supportSave command,
and storage for configuration uploads and downloads
• Two redundant, hot-swappable 1100 W AC/DC power supply units (PSUs) with integral fans
• 3 port-side exhaust DC fan FRUs
NOTE
QSFPs used in the FC16-64 blades (and 8510 core blades) are not compatible with the Brocade 7840.
Brocade 7840 feature licensing
The Brocade 7840 provides the following licensing features:
• Tiered WAN throughput licensing provides coverage of multiple customer segments with one
physical platform:
NOTE
The application throughput numbers shown in the following table assume that some degree of data
compression is occurring. However, Brocade makes no promises, guarantees, or any indication that
some level of compression is possible for customer-specific data. Some data is highly compressible
and some data cannot be compressed. The amount of application throughput varies depending on
data compressibility and the selected compression mode.
