• Secure Fabric OS—Provides flexible security and policy-based administration to protect data
from unauthorized access and corruption. All Secure Fabric OS features are included in the
base Fabric OS beginning with 5.3.0 firmware. Secure Fabric OS can coexist in a fabric
running Fabric OS 5.3.x firmware, but this is not supported with later versions of Fabric OS.
Features of Fabric OS 6.x follow (see the appropriate Fabric OS administrator guide for
configuration restrictions and more information):
• Adaptive Networking with QoS (optional licensed feature)—Provides tools to support high
bandwidth on high-priority connections, ensuring optimum performance, even in congested
networks. This option includes two features: QoS SID/DID Prioritization and Ingress Rate
Limiting. Fabric OS 6.3 includes QoS support for domain, index and WWN zone definitions,
and bottleneck detection for F_Ports. For configuration restrictions, see the HP StorageWorks
Fabric OS 6.x Administrator Guide.
• ICLs (DC SAN Backbone Directors and DC04 SAN Directors only)—Provides dedicated
high-bandwidth links between two DC SAN Backbone Director chassis, without using the
front-end 8 Gb/s ports. Each DC SAN Backbone Director must have the ICL license installed
to enable ICL connections.
• Top talkers (requires Advanced Performance Monitor license)—Provides real-time information
about the top bandwidth-consuming flows passing through a specific point in the network.
• Traffic isolation zones—Enables application segregation, guaranteeing separate paths through
the fabric. You can isolate traffic assigned to ISLs in the fabric.
• Virtual Fabrics—Enables division of a single physical chassis into logical switches, allowing
you to create logical fabrics with other switches. This feature was introduced with Fabric OS
6.2x and is supported on the DC SAN Backbone Director, DC04 SAN Director, and 8/40
and 8/80 SAN switches. Virtual Fabrics is enabled by default on these switches with V6.3.1a
(or later) factory installed.
• Fibre Channel routing and FCIP enhancements—Support for EX_Port Masterless Trunking and
QoS, enhanced compression, FCIP Trunking, and ARL features for the 1606 Extension SAN
Switch and DC Dir Switch MP Extension Blade.
NOTE: Masterless EX_Port Trunking is not supported when using FCIP links in Fabric OS
6.3.0. It is supported in Fabric OS 6.3.0a (or later).
• Encryption enhancements—Supports the System card and Quorum card, tape encryption and
HA clustered key vault beginning with Fabric OS 6.3.0.
NOTE: Advanced Zoning and WebTools are automatically enabled without additional licensing
starting with Fabric OS 6.1x.
Features of Fabric OS 7.x follow (see the HP B-series Fabric OS 7.x Release Notes and appropriate
Fabric OS administrator guide for configuration restrictions and more information):
• In-flight encryption and compression on 16 Gb/s capable ISLs—Provides security for frames
while they are passing between two switches. Compression improves bandwidth utilization
on the ISLs, especially over long distance. Encryption and compression are both disabled by
default but may be enabled at an individual port level.
• Buffer credit loss detection and automatic recovery on 16 Gb/s capable ISLs—Provides support
for the detection and automatic recovery of buffer credits on 16 Gb/s capable ISLs (both ends
of the link must terminate on 16 Gb/s capable ports).
