New Feature Descriptions
Enhanced Optical ICL Topology Support for DCX8510
FOS v7.0.1 supports the following enhanced topologies using optical ICLs:
Support for up to nine DCX8510 chassis in full mesh configuration using optical ICLs
Support for ICL connectivity with up to eight DCX8510 chassis in core-edge topology
This increased support delivers massive scalability, significantly reduces cabling complexity, and also makes
more ports available for device connectivity.
FOS v7.0.1 also adds support for Enterprise ICL license on DCX8510 platforms. Description of this license can
be found in the ―Optionally Licensed Software‖ section of this document.
Support for Dynamic Fabric Provisioning: Fabric Assigned World Wide Name
In order to simplify and accelerate server deployment and improve operational efficiency, FOS v7.0.1 provides
Fabric Assigned WWN or FA-PWWN capability. This feature allows users to create a virtual WWN for a server
instead of using the server’s physical port WWN (PWWN) to create zoning and LUN mapping/masking. When a
FA-PWWN capable server is attached to the SAN, this feature allows the fabric to assign this virtual WWN to
that server. This feature requires servers to be using Brocade HBAs/Adapters. Please consult Brocade
HBA/Adapter driver documentation and Release Notes to confirm minimum requirements for this feature. For
Brocade Network Advisor support, please consult Brocade Network Advisor documentation and Release Notes.
VCS/VDX6730 to FC SAN Connectivity
This feature enables connectivity between hosts (using FCoE) connected to VCS/VDX platforms and FC storage
connected to FC SAN via FCR. An E-port on a VDX6730 platform running NOS v2.1.1 is connected to an
EX_port on an FCR running FOS v7.0.1 to enable this functionality.
Note:
Integrated Routing license is not required to share devices between VDX/VCS Ethernet fabric and FC
SAN fabric.
It is recommended to use 5300, DCX/DCX-4S, DCX8510-8, DCX8510-4 for FCR functionality for higher
scalability.
A new FCR EX_port mode 5 is used to connect VCS/VDX6730 to FCR
FCIP Enhancements
FOS v7.0.1 enables ESCON and Bus/Tag printer emulation support on FCIP platforms.
This feature provides near native performance for FICON Extended paths to remote ESCON or Bus and Tag
printers. Enabling FICON Printer emulation requires the Advanced FICON Acceleration license. This feature is
supported on 7800 and FX8-24.

Optionally Licensed Software
Fabric OS v7.0.1 includes all basic switch and fabric support software, as well as optionally licensed software
that is enabled via license keys.
Optionally licensed features supported in FOS v7.0.1 include:
Brocade Ports on Demand—Allows customers to instantly scale the fabric by provisioning additional ports via
license key upgrade. (Applies to select models of switches).
Brocade Fabric or E_Port—This license enables a switch to connect to a multi-switch fabric via E_Ports, forming
ISL connections. Note: This license is only required on select embedded switch models and does not apply to
any fixed-port or chassis-based platforms. All fixed-port and chassis-based platforms support E_Ports as part
of their default FOS capabilities.
Brocade Extended Fabrics—Provides greater than 10km of switched fabric connectivity at full bandwidth over
long distances (depending on platform this can be up to 3000km
Brocade ISL Trunking—Provides the ability to aggregate multiple physical links into one logical link for
enhanced network performance and fault tolerance. Also includes Access Gateway ISL Trunking on those
products that support Access Gateway deployment.
Brocade Advanced Performance Monitoring—Enables performance monitoring of networked storage resources.
This license includes the Top Talkers feature.
Brocade Fabric Watch —Monitors mission-critical switch operations and provides notification if established
limits or thresholds are exceeded. Fabric Watch includes Port Fencing capabilities.
High Performance Extension over FCIP/FC (formerly known as ―FCIP Services‖) (For the FR4-18i blade) —This
license key also includes the FC-FastWrite feature and IPsec capabilities.
Note: The FC-FastWrite feature is not supported on FR4-18i in FOS v7.0 or later.
Brocade Accelerator for FICON –This license enables unique FICON emulation support for IBM’s Global Mirror
(formerly XRC) application (including Hitachi Data Systems HXRC and EMC’s XRC) as well as Tape Pipelining for
all FICON tape and virtual tape systems to significantly improve XRC and tape backup/recovery performance
over virtually unlimited distance for FR4-18i.
FICON Management Server—Also known as ―CUP‖ (Control Unit Port), enables host-control of switches in
Mainframe environments.
Enhanced Group Management —This license enables full management of devices in a data center fabric with
deeper element management functionality and greater management task aggregation throughout the
environment. This license is used in conjunction with Brocade Network Advisor application software and is
applicable to all FC platforms supported by FOS v7.0 or later.
Adaptive Networking with QoS—Adaptive Networking provides a rich framework of capability allowing a user to
ensure high priority connections obtain the bandwidth necessary for optimum performance, even in congested
environments. The QoS SID/DID Prioritization and Ingress Rate Limiting features are included in this license,
and are fully available on all 8Gb and 16Gb platforms.
Server Application Optimization —When deployed with Brocade Server Adapters, this license optimizes overall
application performance for physical servers and virtual machines by extending virtual channels to the server
infrastructure. Application specific traffic flows can be configured, prioritized, and optimized throughout the
entire data center infrastructure. This license is not supported on the Brocade 8000.
Integrated Routing—This license allows any port in a DCX8510-8, DCX8510-4, Brocade 6510, DCX-4S, DCX,
5300, 5100, 7800, or Brocade Encryption Switch to be configured as an EX_Port or VEX_Port (on some
platforms) supporting Fibre Channel Routing. This eliminates the need to add a dedicated router to a fabric for
FCR purposes.
Encryption Performance Upgrade —This license provides additional encryption processing power. For the
Brocade Encryption Switch or a DCX/DCX-4S/DCX8510-8/DCX8510-4, the Encryption Performance License

Fabric OS v7.0.1 Release Notes v1.0 Page 8 of 67
can be installed to enable full encryption processing power on the BES or on all FS8-18 blades installed in a
DCX/DCX-4S/DCX8510-8/DCX8510-4 chassis.
DataFort Compatibility —This license is required on the Brocade Encryption Switch or DCX/DCX-4S/DCX8510-
8/DCX8510-4 with FS8-18 blade(s) to read and decrypt NetApp DataFort-encrypted disk and tape LUNs.
DataFort Compatibility License is also required on the Brocade Encryption Switch or DCX/DCX-4S/DCX8510-
8/DCX8510-4 Backbone with FS8-18 Encryption Blade(s) installed to write and encrypt the disk and tape LUNs
in NetApp DataFort Mode (Metadata and Encryption Algorithm) so that DataFort can read and decrypt these
LUNs. DataFort Mode tape encryption and compression is supported beginning with the FOS v6.2.0 release on
DCX platforms. Availability of the DataFort Compatibility license is limited; contact your vendor for details.
Brocade 8000 FC Ports on Demand —This license enables all eight FC ports on the Brocade 8000.
Advanced Extension –This license enables two advanced extension features: FCIP Trunking and Adaptive Rate
Limiting. The FCIP Trunking feature allows multiple IP source and destination address pairs (defined as FCIP
Circuits) via multiple 1GbE or 10GbE interfaces to provide a high bandwidth FCIP tunnel and failover resiliency.
In addition, each FCIP circuit supports four QoS classes (Class-F, High, Medium and Low Priority), each as a
TCP connection. The Adaptive Rate Limiting feature provides a minimum bandwidth guarantee for each tunnel
with full utilization of the available network bandwidth without impacting throughput performance under high
traffic load. This license is available on the 7800 and the DCX/DCX-4S/DCX8510-8/DCX8510-4 for the FX8-
24 on an individual slot basis.
10GbE FCIP/10G Fibre Channel –This license enables the two 10GbE ports on the FX8-24 or the 10G FC
capability on FC16-xx blade ports. On the Brocade 6510, this license enables 10G FC ports. This license is
available on the DCX/DCX-4S/DCX8510-8/DCX8510-4 on an individual slot basis.
FX8-24: With this license assigned to a slot with an FX8-24 blade, two additional operating modes (in
addition to 10 1GbE ports mode) can be selected;10 1GbE ports and 1 10GbE port, or 2
10GbE ports
FC16-xx:Enables 10G FC capability on an FC16-xx blade in a slot that has this license
Brocade 6510: Enables 10G FC capability on the switch
Advanced FICON Acceleration –This licensed feature uses specialized data management techniques and
automated intelligence to accelerate FICON tape read and write and IBM Global Mirror data replication
operations over distance, while maintaining the integrity of command and acknowledgement sequences. This
license is available on the 7800 and the DCX/DCX-4S/DCX8510-8/DCX8510-4 for the FX8-24 on an individual
slot basis.
7800 Upgrade –This license allows a Brocade 7800 to enable 16 FC ports (instead of the base four ports) and
six GbE ports (instead of the base two ports). This license is also required to enable additional FCIP tunnels
and also for advanced capabilities like tape read/write pipelining.
ICL 16-link, or Inter Chassis Links -- This license provides dedicated high-bandwidth links between two Brocade
DCX chassis, without consuming valuable front-end 8Gb ports. Each chassis must have the 16-link ICL license
installed in order to enable the full 16-link ICL connections. Available on the DCX only.
ICL 8-Link –This license activates all eight links on ICL ports on a DCX-4S chassis or half of the ICL bandwidth
for each ICL port on the DCX platform by enabling only eight links out of the sixteen links available. This allows
users to purchase half the bandwidth of DCX ICL ports initially and upgrade with an additional 8-link license to
utilize the full ICL bandwidth at a later time. This license is also useful for environments that wish to create ICL
connections between a DCX and a DCX-4S, the latter of which cannot support more than 8 links on an ICL port.
Available on the DCX-4S and DCX platforms only.
ICL POD License –This license activates ICL ports on core blades of DCX8510 platforms. An ICL 1st POD
license only enables half of the ICL ports on CR16-8 core blades of DCX8510-8 or all of the ICL ports on CR16-
4 core blades on DCX8510-4. An ICL 2nd POD license enables all ICL ports on CR16-8 core blades on a
DCX8510-8 platform. (The ICL 2nd POD license does not apply to the DCX8510-4.)
Enterprise ICL License –This license enables connecting more than four DCX8510 platforms within a single
fabric using optical ICLs to deliver massive scalability. This license augments but does not replace existing
licensed ICL support (ICL POD licenses are still required to enable ICL ports) for larger ICL-based topologies of 5

Fabric OS v7.0.1 Release Notes v1.0 Page 9 of 67
to 10 DCX8510 chassis per fabric. This license is required to be installed on every DCX8510 chassis with ICLs
in a fabric when an ICL based topology exceeds the four chassis limit. This license is only
recognized/displayed when operating with FOS v7.0.1 and later.

Recommended Migration Paths to FOS v7.0.1
Migrating from FOS v7.0
Any 8G or 16G platforms running any FOS v7.0.0x release can be non-disruptively upgraded to FOS v7.0.1.
Migrating from FOS v6.4.x
DCX/DCX-4S units running any FOS v6.4.x release can be non-disruptively upgraded to FOS v7.0.1.
Any 8G platforms (other than DCX/DCX-4S) that are currently operating at lower than FOS v6.4.1a must be
upgraded to FOS v6.4.1a or later before non-disruptively upgrading to FOS v7.0.1 Upgrading these platforms
from any FOS V6.4.x release lower than FOS v6.4.1a to FOS v7.0.1 will cause disruption to FC traffic.
Upgrading any 8G platform operating at FOS v6.4.1a or later to FOS v7.0.1 is non-disruptive to FC traffic.
Migrating from FOS v6.4.1_fcoe1
The upgrade from FOS v6.4.1_fcoe1 to FOS v7.0.1 is non-disruptive to both FC and FCoE traffic on DCX and
DCX-4S.
Note: Upgrading from FOS v6.4.1_fcoe or FOS v6.4.x releases other than v6.4.1_fcoe1 to FOS v7.0.1 will be
disruptive to FCoE traffic going through FCOE10-24 blades in DCX/DCX-4S. When loading FOS v7.0.1 with
Brocade Network Advisor v11.1.1/11.1.1a, there is no warning flagging this FCoE traffic disruption.
Migrating from FOS v6.3.x
To non-disruptively migrate from FOS v6.3.x to v7.0.1, units should first load FOS v6.4.1a or later (v6.4.1b
should be used for encryption platforms, units operating in Access Gateway mode, or units with ports
configured as EX or VEX for FCR), and then migrate to FOS v7.0.1.

Fabric OS v7.0.1 Release Notes v1.0 Page 13 of 67
FOS Upgrade and Downgrade Special Considerations
The DCX/DCX-4S units running any FOS v6.4.x can be non-disruptively upgraded to FOS v7.0.1. This upgrade is
non-disruptive to FC traffic only. When loading FOS v7.0.1 to a DCX chassis with FCOE10-24 blades with
Brocade Network Advisor v11.1.1/11.1.1a, there is no warning flagging FCoE traffic disruption.
The DCX/DCX-4S units running FOS v6.4.1_fcoe1 can be non-disruptively upgraded to FOS v7.0.1. This
upgrade is non-disruptive to both FCoE traffic through FCOE10-24 blades and FC traffic.
Non-disruptive upgrade to FOS v7.0.1 on 8G switches is allowed from FOSv6.4.1a or later.
Disruptive upgrades to Fabric OS 7.0.1 are allowed and supported from FOS 6.3 (up to a two-level migration)
using the optional ―-s‖ parameter with the firmwaredownload command.
If there are multiple node EGs (encryption groups) in a fabric, please complete firmwaredownload on one node
at a time before downloading on another node.
The Brocade 8000 does not support non-disruptive hot code loads (HCL). Upgrading the Brocade 8000 to FOS
v7.0 .1 will be disruptive to the I/O through the switch.
FC FastWrite , EX_Ports, and TCP byte streaming on FR4-18i must be disabled prior to upgrading to FOS v7.0.1.
Failure to do so will cause the upgrade to be blocked.
Upgrading a switch currently operating in interopmode 2 or 3 to FOS v7.0.1 is disruptive. The interopmode
must be changed to 0 prior to upgrading to FOS v7.0.1, as interopmodes 2 and 3 are not supported on FOS
v7.0.1. Changing the interopmode is an offline operation.

Brocade Network Advisor Compatibility
Brocade® Network Advisor provides the industry’s first unified network management solution for data, storage,
and converged networks. It supports Fibre Channel Storage Area Networks (SANs), Fibre Channel over Ethernet
(FCoE) networks, Layer 2/3 IP switching and routing networks, wireless networks, application delivery
networks, and Multiprotocol Label Switching (MPLS) networks. In addition, Brocade Network Advisor supports
comprehensive lifecycle management capabilities across different networks through a seamless and unified
user experience. It is the next-generation successor product to legacy Brocade management products (Brocade
Data Center Fabric Manager (DCFM), Brocade Fabric Manager (FM) and Brocade Enterprise Fabric Connectivity
Manager (EFCM)).
Brocade Network Advisor is available with flexible packaging and licensing options for a wide range of network
deployments and for future network expansion. Brocade Network Advisor 11.1.0 is available in
SAN-only edition
IP-only edition
SAN+IP edition.
For SAN Management, Network Advisor 11.1 is available in three editions:
Network Advisor Professional:a fabric management application that is ideally suited for small-size
businesses that need a lightweight management product to manage their smaller fabrics. It manages
one FOS fabric at a time and up to 1,000 switch ports. It provides support for Brocade FC switches,
Brocade HBAs / CNAs, and Fibre Channel over Ethernet (FCoE) switches.
Network Advisor Professional Plus: a SAN management application designed for medium-size
businesses or departmental SANs for managing up to four physical or virtual fabrics (FOS, M-EOS and
Mixed fabrics) and up to 2,560 switch ports. It supports Brocade backbone and director products
(DCX8510-4/DCX-4S, 48Ks, etc.), FC switches, Fibre Channel Over IP (FCIP) switches, Fibre Channel
Routing (FCR) switches/ Integrated Routing (IR) capabilities, Fibre Channel over Ethernet (FCoE) / DCB
switches, and Brocade HBAs / CNAs.
Network Advisor Enterprise:a management application designed for enterprise-class SANs for
managing up to 24 physical or virtual fabrics and up to 9,000 switch ports. Network Advisor SAN
Enterprise supports all the hardware platforms and features that Network Advisor Professional Plus
supports, and adds support for the Brocade DCX Backbone (DCX8510-8/DCX) and Fiber Connectivity
(FICON) capabilities.
More details about Network Advisor’s new enhancements can be found in the Network Advisor 11.1 Release
Notes, Network Advisor 11.1 User Guide, and Network Advisor 11.1 Installation, Migration, & Transition
Guides.
Note:
Brocade Network Advisor 11.0 and DCFM 10.4 cannot manage switches running FOS v7.0 or later.
Brocade Network Advisor 11.1.3 is required to manage Brocade 6505 platform.
DCFM Compatibility
DCFM is not qualified or support the management of switches operating with FOS v7.0 and later firmware
versions. You must first upgrade DCFM to Network Advisor 11.1 or later if you are planning to upgrade devices
to FOS v7.0 or you risk losing management connectivity.
WebTools Compatibility
FOS v7.0.1 is qualified and supported only with Oracle JRE 1.6.0 update 24.

Fabric OS v7.0.1 Release Notes v1.0 Page 15 of 67
SMI Compatibility
It is important to note that host SMI-S agents cannot be used to manage switches running FOS v7.0.1
If users want to manage a switch running FOS v7.0.1 using SMI-S interface, they must use Brocade
Network Advisor’s integrated SMI agent.
Fabric OS Compatibility
The following table lists the earliest versions of Brocade software supported in this release, that is, the earliest
supported software versions that interoperate. Brocade recommends using the latest software versions to get
the greatest benefit from the SAN.
To ensure that a configuration is fully supported, always check the appropriate SAN, storage or blade server
product support page to verify support of specific code levels on specific switch platforms prior to installing on
your switch. Use only FOS versions that are supported by the provider.

Fabric OS v7.0.1 Release Notes v1.0 Page 17 of 67
Zoning Compatibility Note:
Users are recommended to upgrade to the following versions of firmware when interoperating with a switch
running FOS v7.0 or later in the same layer 2 fabric to overcome some of the zoning operations restrictions
that otherwise exist:
Main code level
Patch code levels with full zoning
compatibility
FOS v6.2
FOS v6.2.2d or later
FOS v6.3
FOS v6.3.2a or later
FOS v6.4
FOS v6.4.1 or later
If there are switches running FOS versions lower than the above listed patch levels in the same fabric as a
switch with FOS v7.0 or later, then cfgsave and cfgenable operations initiated from these switches will fail if
the zoning database is greater than 128KB. In such scenarios zoning operations such as cfgsave/cfgenable
can still be performed successfully if initiated from a switch running FOS v7.0 or later.
