Supersedes
FOS 6.3.0a, released October 2009
New features
This section describes new features introduced with FOS 6.3.0.
FCIP enhancements
•FC traffic—Traffic can be transported over an IP network when the 1-GbE or 10-GbE ports are
configured to support FCIP. FOS 6.3.0 and later supports up to 20 FCIP tunnels on a DC SAN
Director Multiprotocol Extension Blade, and 8 FCIP tunnels on the 1606 Extension SAN Switch.
The FCIP tunnels on the local and remote GbE ports act as the Virtual E_Ports (VE_Ports), connecting
the local and remote fabrics. Performance is optimized for FCP and FICON traffic using batch-
ing/debatching operations on all data and command frames/IUs. This prevents fragmentation of
multiple 2,112-size FC frames (batch) into smaller IP frames, compared to single-frame exchanges
(for example, FC frame generators).
•FCIP Trunking—This is a new feature available on the DC SAN Director Multiprotocol Extension
Blade and 1606 Extension SAN Switch that virtualizes two or more TCP connections as part of a
single FCIP tunnel. These connections, called circuits, are configured explicitly to be part of an
FCIP tunnel. Their primary purpose is to increase the tunnel bandwidth and provide failover paths
in the event of a network failure. FCIP Trunking functionality and the additional TCP connections
are transparent to the applications using the FCIP tunnel. FCIP Trunking requires the optional Ad-
vanced Extension license.
•Advanced Compression—The 1606 Extension SAN Switch allows FC data frames to be compressed
on a per-tunnel basis before they are sent over the tunnel as FCIP frames. The FC command frames
and all frames generated from or destined for the CP are not compressed, even when compression
is enabled on a tunnel. The uncompressed and compressed packets and bytes are counted and
maintained on a per-tunnel basis. The compression ratio can be found for a given polling interval
by reading the number of compressed and uncompressed bytes. The compression is performed
by the hardware on a frame-by-frame basis, and is performed on FC data frames in the ingress
direction before they are encapsulated as FCIP frames.
HP StorageWorks FOS 6.3.0b Release Notes 5

NOTE:
Advanced Compression is supported only with FOS 6.3.0a and later.
•Adaptive Rate Limiting (ARL)—The DC SAN Director Multiprotocol Extension Blade and 1606
Extension SAN Switch allow an FCIP tunnel connection to dynamically change the rate at which
the tunnel transmits data through the TCP connections. ARL uses the information from the TCP
connections to determine and adjust the rate limit for the FCIP tunnel dynamically. This allows FCIP
connections to use the maximum available bandwidth. ARL requires the optional Advanced Extension
license.
FCR enhancements
•EX_Port Trunking—This feature was first introduced with FOS 5.2.0. In that release, when a
master EX_Port in a trunk group goes offline, you must select a new area (master port). This causes
all slave EX_Ports of that trunk group to be disabled and brought online to select a new master
EX_Port. The Masterless EX_Port feature (introduced with FOS 6.3.0a) uses the dynamic port
binding capability first introduced with FOS 6.2 to reassign the trunk area from the old master
port to the new master port. With the master port offline condition, one of the slave ports becomes
the new master port, and all of the other slave ports remain online. The new master port uses the
old master port’s area, and the old master port gets a new/unused area. The PID of the trunk does
not change with the master port offline condition.
•Adaptive Networking—New features were first introduced with FOS 6.0, including FC QoS, which
allows users to establish flow-based prioritization of traffic over a SAN. FOS 6.3 extends QoS
over FCR configurations, allowing support of QoS for traffic flows originating in an edge fabric,
passing through the FC backbone fabric, and then continuing to a destination edge fabric. This
feature requires configuration of both LSAN zones and QoS zones, and requires that the Adaptive
Networking license be installed on switches in both the edge and backbone fabrics.
Adaptive Networking enhancements
If one or more applications running on the data center fabric are slowing down, the administrator
can enable the new Bottleneck Detection feature on all suspected edge switches to which F_Ports are
attached. Using this feature, the administrator can determine whether there are any slow-draining
devices causing network congestion. When this feature is enabled and a switch detects a condition
where the offered load exceeds the rate at which the destination device can accept frames, a RASLog
message is generated and the administrator can view historic statistics logs for the port to investigate
the problem. This new capability is considered part of the Adaptive Networking feature set, but does
not require a license. This feature is available on all 4-Gb and 8-Gb ports.
Enhanced native connectivity with McDATA products
•FOS-based platforms operating in interopmode 3 can now participate in Mi10K fabrics using
239 DID mode. Previously, connecting to such fabrics could only be done through FCR.
•FOS-based platforms operating in either interopmode 2 or 3 can now participate in M-EOS fabrics
using nondefault DID Base Offset settings.
NOTE:
For specific information HP support for B-series and M-series interop fabrics, see the HP StorageWorks
Merging Fabrics Based on M-series and B-series Fibre Channel Switches Application Notes .

CEE/FCoE features
•802.1x defines a client/server-based authentication protocol for port access control. It prohibits
unknown/unauthorized clients from connecting to an Ethernet network through publicly accessible
ports. The authentication server component of the system authenticates each client device or host
connected to an authentication-enabled network port. Until the client is authenticated, 802.1x allows
only the authentication protocol traffic (EAPOL) on the connected port. Once authentication is
successful, the port is open for all network traffic.
•The FIP VLAN Discovery protocol is supported with the following caveat:
The FIP VLAN DISCOVERY request must be received with either a priority-only VLAN tag (VLAN
ID=0), or a VLAN tag with VLAN ID=FCoE VLAN. FIP VLAN DISCOVERY request received with
a valid VLAN ID in the tag that is not equal to the FCoE VLAN is dropped. The expected behavior
is that the converged network adapter (CNA) will send a priority-tagged FIP VLAN DISCOVERY
request.
Optionally licensed software
Optionally licensed features in FOS 6.3.0 are as follows:
•Ports on Demand—Allows customers to instantly scale the fabric by provisioning additional ports
through a license key upgrade (applies to select switch models).
•Extended Fabrics—Provides greater than 10 km of switched fabric connectivity at full bandwidth
over long distances. (Depending on the platform, the distance can be up to 3,000 km.)
•ISL Trunking—Enables aggregation of multiple physical links into one logical link for enhanced
network performance and fault tolerance. It also includes Access Gateway ISL Trunking on the
products that support the Access Gateway deployment.
•Advanced Performance Monitoring—Enables performance monitoring of networked storage re-
sources. This license includes the Top Talkers feature.
•High-Performance Extension over FCIP/FC (formerly known as FC-IP Services)—For the HP Storage-
Works B-series Multiprotocol Router Blade and 400 MP Router, this license key also includes the
FC FastWrite (FCFW) feature and IPsec capabilities.
•Accelerator for FICON 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 the 400 MP Router and B-series
Multiprotocol Router Blade.
•Fabric Watch—Monitors mission-critical switch operations, and now includes new Port Fencing
capabilities.
•FICON Management Server (also known as the control unit port [CUP])—Enables host control of
switches in mainframe environments.
•16 Link Inter-chassis links (ICL 16 link)—Provide dedicated high-bandwidth links between two DC
SAN Backbone Director chassis, without consuming valuable front-end 8-Gb ports. Each DC
Backbone Director must have the ICL license installed in order to enable ICL connections (available
on the DC Backbone Director only).
•8 Link Inter-chassis links (ICL 8 link)—This license activates all 8 links on ICL ports on a DC04 SAN
Director chassis for connection of two DC04 directors, or half of the ICL bandwidth for each ICL
port on the DC SAN Backbone Director platform by enabling only 8 of the 16 links available.
This allows users to purchase half the bandwidth of DC SAN Backbone Director ICL ports initially,
and then upgrade with an additional 8-link license to utilize the full ICL bandwidth.
This license is also useful for environments in which you want to create ICL connections between
a DC SAN Backbone Director and a DC04 SAN Director. (The DC04 SAN Director can support
HP StorageWorks FOS 6.3.0b Release Notes 7

only 8 links on an ICL port.) This license is available on the DC04 SAN Director and DC SAN
Backbone Director platforms only. It replaces the original ICL license for the DC04 SAN Director
and is new for the DC SAN Backbone Director.
•Adaptive Networking—Ensures high-priority connections and obtains the network resources neces-
sary for optimum performance, even in congested environments. The QoS SID/DID Prioritization
and Ingress Rate Limiting features are the first components of this license and are available on all
8-Gb platforms.
•Integrated Routing license—Allows ports on a DC SAN Backbone Director, DC04 SAN Director,
1606 Extension SAN Switch, HP StorageWorks 8/80 SAN Switch, or HP StorageWorks 8/40
SAN Switch to be configured as EX_Ports, supporting FCR. This eliminates the need to add a B-
series Multiprotocol Router Blade or to use the 400 MP Router for FCR purposes, it also provides
double the bandwidth for each FCR connection (when connected to another 8-Gb-capable port).
•Encryption Performance Upgrade—This license provides additional encryption processing power.
The Encryption Performance License enables full encryption processing power on the HP Storage-
Works Encryption SAN Switch or on all HP StorageWorks DC Switch Encryption blades installed
in the DC SAN Backbone Director/DC04 SAN Director chassis.
•Server Application Optimization license (introduced with FOS 6.2)—When deployed with Brocade
HBAs, 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 data center infrastructure.
•1606 Extension SAN Switch Port Upgrade—This new license allows a 1606 Extension SAN Switch
to enable 16 FC ports (instead of the base 4 ports) and 6 GbE ports (instead of the base 2 ports).
This license is also required to enable additional FCIP tunnels and advanced capabilities, such as
tape read/write pipelining. A 1606 Extension SAN Switch must have the Port Upgrade license
installed to add FICON Management Server (CUP) or Advanced Accelerator for FICON.
•Advanced Extension—This new license enables two advanced extension features: FCIP Trunking
and ARL. The FCIP Trunking feature allows multiple IP source and destination address pairs (defined
as FCIP circuits) via multiple 1-GbE or 10-GbE interfaces to provide a high-bandwidth FCIP tunnel
and failover resiliency. Each FCIP circuit also supports four QoS classes (Class-F, Hi, Medium,
and Low Priority), each as a TCP connection. The ARL 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 1606 Extension
SAN Switch and DC SAN Backbone Director/DC04 SAN Director for the DC SAN Director
Multiprotocol Extension Blade on an individual slot basis.
•10-GbE FCIP—This new license enables the two 10-GbE ports on the DC SAN Director Multiprotocol
Extension Blade. With this license, two additional operating modes (in addition to 10 1-GbE ports
mode) can be selected:
•10 1-GbE ports and 1 10-GbE port
•2 10-GbE ports
This license is available on the DC SAN Backbone Director/DC04 SAN Director for the DC SAN
Director Multiprotocol Extension Blade on an individual slot basis.
Included licensed software
•Enhanced Group Management—This license is included with all HP 8-Gb switches. Enhanced
Group Management enables full management of the device in a data center fabric, with increased
element management functionality and management task aggregation throughout the environment.
This license is used in conjunction with the DCFM application software.
•2408 FCoE Converged Network Switch FC Ports on Demand—This new license enables all eight
FC ports on the 2408 FCoE Converged Network Switch.
8

IMPORTANT:
Most 2408 FCoE Converged Network Switch units shipped with FOS 6.1.2_cee1 did not include
this license and must have it installed before upgrading to FOS 6.3.0. Failure to do so will result
in the disabling of FC ports after the upgrade. Contact HP Support to obtain this license key if
your 2408 switch does not already have it installed.
•FCoE—This license enables Fibre Channel over Ethernet functionality on the 2408 FCoE Converged
Network Switch. Without the FCoE license, the 2408 FCoE Converged Network Switch is a pure
Layer 2 Ethernet switch and will not support FCoE bridging or FCoE Forwarding (FCF) capabilities.
Temporary license support
HP does not currently support temporary licenses or Universal Temporary Licenses.
Previously licensed software now included with base FOS
The capabilities described in this section are included as part of the base FOS. No additional purchase
or licensing is necessary.
NOTE:
Starting with FOS 6.1, Advanced Zoning and WebTools licenses are not necessary. These features
are enabled automatically on all products running FOS 6.1 or later.
