Brocade Extension concepts
Brocade Extension products support FC/FICON based data ows as well as IP based storage data ows.
Brocade Extension enables you to use the existing IP wide are network (WAN) infrastructure to connect Fibre Channel and IP fabrics.
Brocade Extension supports applications such as remote data replication (RDR), centralized backup, and data migration over very long
distances that are impractical or very costly using native Fibre Channel or IP connections. Extension tunnels, built on a physical
connection between two extension switches or blades, allow Fibre Channel and IP I/O to pass through the IP WAN.
The extension tunnel and TCP connections ensure in-order delivery of Fibre Channel (FC) and IP frames and lossless transmission. The
Fibre Channel fabric and all targets and initiators, whether FC or IP, are unaware of the presence of the IP WAN.
Brocade IP Extension concepts
The Brocade 7840 Extension switch supports IP based storage data ows as well as FC/FICON based data ows. IP extensions provide
enterprise-class support for IP storage applications, using existing IP wide area network (WAN) infrastructure. IP Extension features are
oered only on the Brocade 7840 Extension Switch platform.
IP data ows across Brocade tunnels are referred to as IP Extension. IP Extension provides storage administrators with the means to
monitor and manage their IP storage ows across an IP infrastructure.
IP Extension enables you to use the existing IP WAN infrastructure to connect IP storage. Additionally, IP Extension gives you visibility
and control of ows using various diagnostic tools, IPsec, compression, QoS, Extension Trunking, and lossless tunnel resiliency. IP
Extension supports applications such as array native IP remote data replication (RDR), IP based centralized backup, VM replication; host
based and database replication over IP, NAS head replication between data centers, data migration between data centers and others.
Brocade WAN Optimized TCP (WO-TCP) ensures in-order lossless transmission of IP Extension data. IP Extension establishes a proxy
TCP endpoint for local devices. Local devices are unaware and unaected by the latency and quality of the IP WAN. This accelerates end
device native TCP. IP Extension data across the IP WAN uses WO-TCP, a highly ecient and aggressive TCP stack for moving data
between data centers.
IP Extension provides the following advantages:
• Data Center Interconnect (DCI) — Unied support and management of both FC/FICON and IP
• Storage Administrators — Provision once and over time connect many devices
• High performance for high speed WAN links (one or more 10 Gbps and 40 Gbps links)

• WAN bandwidth pooling — pool bandwidth from multiple links/providers
• Lossless link loss (LLL)
• Adaptive Rate Limiting (ARL)
• Network resiliency and high availability using Extension Trunking
• Ecient protocol transport — negligible added overhead

VE_Ports and VEX_Ports
Any FC communications between switches that include fabric services needs to communicate across an ISL using E_Ports. There are
various types of E_Ports:
• E_Port
• EX_Port
• VE_Port
• VEX_Port
VE and VEX ports are virtual because they are extension tunnel facing. These are the ports that enable communication across an
extension tunnel. EX and VEX ports are FC Routed ports. Router ports are the demarcation point of fabric services for a fabric. Fabric
services do not extend beyond an EX or VEX port.

E port types No FCR FCR
Native FC E_Port EX_Port
Extended over tunnel VE_Port VEX_Port
NOTE
VEX_Ports are not supported on the Brocade 7840 switch.
Once the tunnels are congured and the WO-TCP connections are made for a circuit, a logical interswitch link (ISL) is established
between the switches. VE_Ports operate like E_Ports for all fabric services and Fabric OS operations, except that VE_Ports use TCP/IP
and Ethernet as the transport instead of FC.
A "virtual" EX_Port exposed by the extension tunnel to form an ISL connection allows you to congure a virtual EX_Port or VEX_Port to
support FCR demarcation. From the point of view of a switch in an edge fabric, a VEX_Port appears as a normal E_Port. It follows the
same Fibre Channel protocol as other E_Ports. However, VEX_Ports terminate the attached fabric at the port and do not allow fabrics to
merge by propagating fabric services or routing topology information beyond that edge fabric. This provides edge fabric,or remote edge
fabric isolation outward from the EX_Port or VEX_Port.
NOTE
VE_Ports or VEX_Ports cannot connect in parallel to the same domain at the same time as Fibre Channel E_Ports or
EX_Ports.
An extension tunnel is assigned to a VE_Port or VEX_Port on the switch or blade at each end of the tunnel. Because multiple VE_Ports
and VEX_Ports can exist on the extension switch or blade, you can create multiple tunnels.
Fibre Channel frames enter an extension tunnel through virtual E_Ports (VE_Ports) or virtual extension ports (VEX_Ports) and are
encapsulated and passed to TCP layer connections. A Data Processing (DP) complex on the switch or blade handles the FC frame
encapsulation, de-encapsulation, and transmission to the TCP link.
Extension interfaces, circuits, and trunks
A circuit is a connection between a pair of IP addresses that are associated with source and destination endpoints of an extension tunnel.
Circuits provide the links for trac ow between source and destination interfaces that are located on either end of the tunnel. For each
tunnel, you can congure a single circuit or a trunk consisting of multiple circuits. Multiple circuits can be congured per Ethernet port by
assigning them unique IP interfaces (IPIFs). When you congure a circuit, you provide the IP addresses for its source and destination
interfaces.
You must congure unique IPIFs at the endpoint of each circuit. An IPIF consists of an IP address for a circuit endpoint, subnet mask,
and an MTU size. For the Brocade 7840 switch, the IPIF can also contain a VLAN ID for VLAN tagging and the ability to enable PMTU.
If the remote IPIF is not on the same subnet as the local IPIF, you must congure an IP route to that destination specifying the gateway
to use. You can dene a specic number of routes per IPIF based on the extension platform. Refer to Tunnel and circuit requirements on
page 57 for specications. An Ethernet interface can contain multiple IPIFs.
NOTE
In this publication, the "source" or "local" is the switch you are conguring, while the "destination" or "remote" is the switch on the
other end of the tunnel.
Congure an extension tunnel by specifying a VE_Port for a source and destination interface. When you congure a circuit on the tunnel,
you will provide two IP addresses, one for the source and one for the destination IP interface.
For Extension Hot Code Load (HCL) tunnels, four IP addresses are congured per circuit, which includes both endpoints. The four
addresses are the local and remote IP addresses, and the local and remote HA IP addresses used by HCL. In most instances, the two
local IP addresses are in the same subnet and the two remote IP addresses are in the same subnet. All IP addresses must be able to

communicate across the IP infrastructure. Extension HCL is supported only on the Brocade 7840. For additional information, refer to
Conguring Extension HCL on page 82.
FIGURE 2 Extension tunnel and circuits
An extension trunk is a tunnel consisting of multiple circuits.
For specications and restrictions on tunnels, circuits, and trunks for the Brocade 7800 Extension Switch, 7840 Extension Switch, and
the FX8-24 Extension Blade, refer to the Extension Features on Brocade Extension Switches and Blades chapter.
Extension Trunking
Extension Trunking is a method for managing the use of WAN bandwidth and providing redundant paths over the WAN that can protect
against transmission loss due to WAN failure. Extension Trunking also provides granular load balancing on a weighted round-robin basis
per batch. Trunking is enabled by creating multiple circuits within a tunnel so that the tunnel utilizes multiple circuits to carry
trac
between multiple source and destination addresses. For circuit capacities for Brocade extension switches and blades, refer to Tunnel and
circuit requirements on page 57.
Redundancy and fault tolerance
Multiple extension tunnels can be
dened between pairs of extension switches or blades, but doing so defeats the benets of a multiple-
circuit extension tunnel. Dening two tunnels between a pair of switches or blades is not as redundant or fault-tolerant as having multiple
circuits in one tunnel.
Extension Trunking provides lossless link loss (LLL). LLL ensures all data lost in ight is retransmitted and placed back in order prior to
being delivered to upper layer protocols. This is an essential feature to prevent interface control checks (IFCCs) on mainframes using
FICON and SCSI timeouts for open-system-based replication. For more information about LLL on specic Brocade extension switches
and blades, refer to Circuit failover on page 61.
NOTE
When you create multiple parallel tunnels between the same switch domains, you must enable Lossless Dynamic Load Sharing
(DLS). This is because there can be routing updates that will occur when tunnels come up or go down. Each routing update can
cause dropped, or unrouteable frames if the destination is via the peer tunnel connected switch domain.

Brocade Fabric OS Extension Conguration Guide, 7.4.x

Tunnel restrictions for Fibre Channel Protocol and FICON Acceleration
Multiple extension tunnels within the same switch are not supported between pairs of extension switches or blades when protocol
optimization features—FastWrite, OSTP, and FICON Acceleration—are enabled on the tunnel, unless Trac Isolation (TI) zones or logical
switch/logical fabric (LS/LF) congurations are used to provide deterministic ows between the switches. These features require
deterministic FC frame routing between initiators and targets when multiple tunnels or VE_Ports exist. Non-controlled, parallel (equal-
cost multi-path) tunnels are not supported between domains when protocol optimization is enabled on one or more tunnels without
controlling the routing of SID/DID pairs to a specic tunnel using TI Zones or Virtual Fabrics (VF) LS/LF congurations.
Note the following additional restrictions:
• FICON networks with or without FICON Acceleration do not support exchange-based routing (EBR) congurations.
• The recommended best practice is to have identical FOS versions at both ends of an extension tunnel.
• When planning Fabric OS upgrades or downgrades, it is recommended that you upgrade or downgrade both endpoints of an
extension tunnel with the same FOS version.
• When conguring tunnels to support large numbers of devices, consider memory limitations of the Brocade extension switch or
blade if you are enabling any type of protocol optimization feature. If too many devices are present or activated at one time,
protocol optimization such as FICON Acceleration can be negatively impacted. Refer to Memory use limitations for large-
device tunnel congurations on page 26.
IP WAN network considerations
Because Brocade Extension tunnels use TCP connections over an existing wide area network, consult with the WAN carrier and IP
network administrator to ensure that the network hardware and software equipment operating in the data path can properly support the
TCP connections. Keep the following considerations in mind:
• Routers and
rewalls that are in the data path must be congured to pass trac through a specic TCP port on the switch. If
IPsec is used, the network must allow Encapsulating Security Payload (ESP) trac to pass through (UDP port 500). The
Brocade WO-TCP implementation selects a port between 49152 and 65535 as the ephemeral (or initiating) port to open up
to port 3225 and 3226.
• On the Brocade 7840 switch, the TCP URG ag is frequently set. This ag indicates the beginning of a tunnel header in the
TCP packet. Make sure these ags are not dropped from ports 3225 and 3226.
• The Brocade 7800 switch and Brocade FX8-24 blade use TCP port 3225.
• The Brocade 7840 switch uses ports 3225 and 3226.
• To enable recovery from a WAN failure or outage, be sure that diverse, redundant network paths are available across the WAN.
• Be sure the underlying WAN infrastructure can support the redundancy and performance expected in your implementation.
Adaptive Rate Limiting
Adaptive Rate Limiting (ARL) is performed on circuits to change the rate in which the tunnel transmits data through the IP network. ARL
uses information from the TCP connections to determine and adjust the rate limit for the circuit dynamically. This allows connections to
utilize the maximum available bandwidth while providing a minimum bandwidth guarantee. ARL is
congured on a per-circuit basis
because each circuit may have available dierent amounts of bandwidth.
ARL is supported only if Fabric OS v7.0.0 and later is running on both ends of the tunnel. For Fabric OS v7.0.0 and later, you can
congure minimum and maximum rates for each circuit of a tunnel using the following ports:
• XGE (10 GbE) ports on the Brocade FX8-24 blade (xge0 and xge1).
Adaptive Rate Limiting
Brocade Fabric OS Extension Conguration Guide, 7.4.x
53-1003507-09 19
• 10G (1/10 GbE) ports on the Brocade 7840 switch (ge2-ge17).
• 40 GbE ports on the Brocade 7840 switch (ge0 and ge1).
• 1 GbE ports on the Brocade 7800 switch (ge0-ge5) and Brocade FX8-24 blade (ge0-ge9).
ARL applies a minimum and maximum trac rate, and allows the trac demand and WAN connection quality to determine the rate
dynamically. If trac is owing error-free over the WAN, the rate grows towards the maximum rate. If TCP reports an increase in
retransmissions, the rate reduces towards the minimum. ARL never attempts to exceed the maximum congured value and reserves at
least the minimum congured value.
For ARL limitations and features specic to supported products, refer to the Extension Features on Brocade Extension Switches and
Blades on page 31 chapter.
Brocade 7840 Switch support for ARL
ARL on the Brocade 7840 has been enhanced to react ten times faster to varying
trac patterns that compete for WAN bandwidth or
use shared interfaces.
ARL has always accommodated shared bandwidth; however, the amount of storage data using Extension connections continues to grow
and consume larger and faster links. On the Brocade 7840, the enhanced response time of ARL provides faster rate limiting adaptation,
which permits optimized throughput of not only Extension trac, but also the competing ows.
The back-o mechanism implemented by ARL is optimized to increase overall throughput. ARL dynamically preserves bandwidth and
evaluates network conditions to see whether additional back-os are required.
ARL maintains Round Trip Time (RTT) stateful information to better predict network conditions and to allow intelligent and granular
decisions about proper adaptive rate limiting. When ARL encounters a network error, it looks back at prior stateful information, which will
be dierent relative to the current state. Rate limit decisions are then modied using the ARL algorithm. When congured for automatic
selection, ARL will dynamically determine which algorithm to use based on the changing network conditions.
FSPF link cost calculation when ARL is used
Fabric Shortest Path First (FSPF) is a link state path selection protocol that directs
trac along the shortest path between the source and
destination based upon the link cost. When ARL is used, the link cost is equal to the sum of the maximum trac rates of all established,
currently active low metric circuits in the tunnel. The following formulas are used:
• If the bandwidth is greater than or equal to 2 Gbps, the link cost is 500.
• If the bandwidth is less than 2 Gbps, but greater than or equal to 1 Gbps, the link cost is 1,000,000 divided by the bandwidth in
Mbps.
• If the bandwidth is less than 1 Gbps, the link cost is 2000 minus the bandwidth in Mbps.
When running multiple parallel tunnels, set the static link costs if you want all tunnels used at all times. Otherwise, a circuit outage can
take a tunnel out of service because of a link cost change. If multiple parallel tunnels are used, congure Lossless DLS. This avoids circuit
bounce because of disruptive bandwidth updates.
Conguring ARL
To congure the minimum and maximum committed rates for ARL on a circuit, refer to Tunnel conguration options on page 80.
