Overview of Brocade 7840 Extension Switch
The Brocade 7840 Extension Switch is intended as a platform for Fibre Channel over IP (FCIP). This enables transmission of Fibre
Channel data over long distances by way of IP networks by wrapping Fibre Channel frames in IP packets. Each end of the FCIP
communication path must be a compatible FCIP device.
The switch can operate independently or in a fabric containing multiple extension switches.
Brocade 7840 software features
The Brocade 7840 provides the following software features:
• Multiple logical FCIP tunnels with maximum tunnel bandwidth up to 20Gbps allow for scalable connectivity between sites. Note
that the 7840 does not support FCIP connectivity with any other products including the Brocade 7800 and FX8-24.
• FCIP Trunking feature allows multiple IP source and destination address pairs (dened as FCIP circuits) via multiple 1/10GbE
or 40GbE interfaces to provide high bandwidth FCIP tunnel and lossless failover resiliency. In addition, each FCIP circuit
supports four QoS classes (Class-F, High, Medium and Low Priority), each as a TCP connection.
• ARL feature meets minimum bandwidth guarantee for each tunnel while making the full utilization of the available network
bandwidth without adverse throughput performance impact at high trac load.
• Hardware-based compression delivers the ability to maximize throughput over lower bandwidth links in the wide area network,
optimizing the cost eciencies of FCIP. The 7840 compresses FC frames before they are encapsulated into FCIP packets.
• Key protocol features are enabled in the FCIP implementation to optimize performance of Extension over IP networks, including
FX8-24 and WAN Optimized TCP (WO-TCP), 9K jumbo frame and end-to-end Path MTU auto discovery.
• Hardware-based IPsec supports mix of secure and non-secure tunnels on the same Ethernet port, jumbo frames, and VLAN
tagged connections. The Brocade 7840 IPsec function is capable of supporting both IPv4 and IPv6.
• FastWrite, Open Systems Tape Pipelining and Advanced Accelerator for FICON mitigate the latency eect of a long distance
FCIP distance connection over IP WAN.
• FCIP HCL (Hot Code Load) provides In-service rmware upgrade for supporting 24/7 non-stop business operations
• Built-in WAN link tester generates trac over an IP connection to test for maximum throughput, congestion, loss percentage,
out of order deliver, latency, and other network conditions. It helps determine the health of a WAN link before deploying it for
use.
• Fabric Vision advanced monitoring provides the following functions:
– Policy based monitoring monitors FCIP connectivity and WAN anomalies using multi-layer metrics.
– Flow monitoring reports IOPS and data rate of individual I/O ows of inter-DC replication and tape backup operations.
– Flow generator generates FC frames for a dened ow with default or custom size and pattern and sent across FCIP tunnel
to help validate end to end network setup and conguration.

• One RJ-45 Ethernet management port with 10/100/1000 Mbps autonegotiating capability
• One USB port that provides storage for rmware updates, output of the supportSave command, and storage for conguration
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.
DANGER
Batteries used for RTC/NVRAM backup are not located in operator-access areas. There is a risk of explosion if a battery
is replace by an incorrect type. Dispose of used components containing batteries according to the local ordinance and
regulations.
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-specic 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.

Recommendations for cable management
Cables can be organized and managed in a variety of ways, such as by using cable channels or patch panels. Note the following
recommendations:
• Plan cable management before installing the device in a rack.
• Leave at least 1 meter (3 feet) of slack for each port cable. This provides room to remove and replace the device, allows for
inadvertent movement of the rack, and helps prevent the cables from being bent to less than the minimum bend radius.

Brocade 7840 Extension Switch Hardware Installation Guide
NOTE
A 50-micron cable should not be bent to a radius less than 2 in. under full tensile load and 1.2 in. with no tensile load. Tie
wraps are not recommended for optical cables because they are easily overtightened.
