New feature descriptions

This section describes the new features that were introduced in Fabric OS 6.2.0a, and brought forward

with Fabric OS 6.2.0g.

Virtual fabrics

•Virtual Fabrics (VF) is a new capability supported on the HP StorageWorks DC SAN Backbone

Director, DC04 SAN Director, HP StorageWorks 8/80 SAN Switch, and HP StorageWorks 8/40

SAN Switch. Once enabled, VF allows the user to divide a single physical chassis or switch into

multiple logical switches by assigning individual ports to a logical switch. Each logical switch is

managed as a completely independent layer 2 Fibre Channel switch, and can be deployed in

independent fabrics known as logical fabrics.

•VF also allows the user to create a special logical switch known as the base switch, which is used

for connectivity to other base switches and also as a backbone fabric for Fibre Channel Routing.

Individual logical fabrics can utilize this shared base fabric for connectivity to other switches,

providing efficient use of resources by sharing common ISL and ICL connections among multiple

logical fabrics.

•VF is part of the base Fabric OS and does not require a license. VF is fully compatible with legacy

Brocade products as well as M-series switches and directors.

FCR and FCIP enhancements

•FCIP (SCSI) Read Tape Pipelining anticipates host read operations and buffers data to reduce

latency from the FCIP WAN.

•LSAN Tagging provides special behavior for designated LSAN zones using either a new speed

tag or enforce tag. The enforce tag allows individual FCRs to be configured only to import devices

in specific LSAN zones, increasing scalability. The speed tag allows designated targets to remain

imported, allowing sensitive hosts to discover targets much faster. This is useful when performing

boot over LSAN operations

•SoTCP Enhancements improve network congestion management in Slow Start Mode and helps

prevent host I/O timeouts.

•Support for Pathinfo over MetaSAN. The Pathinfo command has been enhanced to provide

path information across routed fabrics, which is especially useful when troubleshooting connectivity

problems across routed fabrics.

•FSPF cost in the FCR backbone fabric uses the most efficient route to reach a destination fabric,

preventing the use of an FCIP link when an ISL is available.

•In-band management link over FCIP connections for the 400 MP Router allows a management

station to communicate with a remote 400 MP Router through the GE ports. This allows a single

management station located on the WAN side of the 400 MP Router to communicate with the

management interface on the CP for management tasks such as firmware downloads, SNMP

polling, SNMP traps, trouble shooting, and configuration.

Enhanced Native Connectivity with McDATA products

•Fabric OS 6.2 and M-EOS 9.9 now support Frame Redirection in McDATA Open Fabric Mode

(interopmode 3) fabrics. Frame Redirection zones must be created and activated from Fabric OS

platforms.

•Fabric OS platforms now support EX_Port connections to McDATA Open Fabric Mode Mi10Ks

using the 239 DID setting.

Security enhancements

•Configurable stateless IPv6 auto-configuration is supported.

HP StorageWorks Fabric OS 6.2.0g release notes 5

•IPsec with IPv6 support provides greater security for management ports and configurable security

policies for IPv4/6 addresses.

•A switch-wide policy requiring HBA authentication requires that the FC-SP bit be set in FLOGI. If

the bit is not set, the FLOGI is rejected and the port is disabled.

•A new warning for RADIUS login allows users to specify how many days in advance they should

be notified of password expiration.

•An LDAP enhancement adds the ability to provide an alternate UPN (userPrincipalName) to domain

authentication.

Contact your switch vendor for information about other backup applications.

Optionally licensed software

The following are optionally licensed features in Fabric OS 6.2:

•Ports on Demand allows customers to instantly scale the fabric by provisioning additional ports

via 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 platform, the distance can be up to 3000 km).

•ISL Trunking provides the ability to aggregate multiple physical links into one logical link for en-

hanced network performance and fault tolerance. This also includes Access Gateway ISL Trunking

on the products that support Access Gateway deployment.

•Advanced Performance Monitoring enables performance monitoring of networked storage resources.

This license includes the TopTalkers feature.

•High-Performance Extension over FCIP/FC (formerly known as FC-IP Services) for the HP Storage-

Works B-series Multi-protocol Router blade and 400 MP Router). This license key also includes the

FC-Fast Write feature and IPsec capabilities.

•The 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 Multi-protocol Router blade.

•Fabric Watch monitors mission-critical switch operations, and now includes new Port Fencing

capabilities.

•The FICON Management Server (also known as CUP or Control Unit Port) enables host-control of

switches in mainframe environments.

•Inter Chassis Links (ICLs) provide dedicated high-bandwidth links between two HP StorageWorks

DC SAN Backbone Directors or DC04 SAN Director switch chassis, without consuming valuable

front-end 8G ports. Each DC Backbone Director/DC04 SAN Director must have the ICL license

installed in order to enable the ICL connections (available on the DC Backbone Director/DC04

SAN Director only).

•Adaptive Networking allows a user to ensure high priority connections and obtain the network

resources necessary 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 8G platforms.

•The Integrated Routing license allows ports in an HP StorageWorks DC SAN Backbone Director,

HP StorageWorks DC04 SAN Director, HP StorageWorks 8/80 SAN Switch, or HP StorageWorks

8/40 SAN Switch to be configured as EX_Ports, supporting Fibre Channel Routing. This eliminates

the need to add a B-series Multi-protocol Router blade or use the 400 MP Router for FCR purposes,

and also provides double the bandwidth for each FCR connection (when connected to another

8G-capable port).

•The Server Application Optimization license (introduced with Fabric OS 6.2) when deployed with

server adapters, 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.

Included licensed software

The Enhanced Group Management license is included with all HP 8Gb switches. Enhanced Group

Management enables full management of the device in a datacenter fabric with deeper element

management functionality and greater management task aggregation throughout the environment.

This license is used in conjunction with Data Center Fabric Manager (DCFM) application software.

Temporary license support

Temporary licenses are not currently supported by HP.

Previously licensed software now part of base Fabric OS

The following capabilities are included as part of the base Fabric OS and no additional purchase or

licensing is necessary.

NOTE:

Advanced Zoning and Web Tools licenses are no longer necessary, beginning with Fabric OS 6.1.

These features are automatically enabled on all products running Fabric OS 6.1 or later

Standards compliance

This software conforms to the Fibre Channel standards and to accepted engineering practices and

procedures. In certain cases, HP might add proprietary supplemental functions to those specified in

the standards. For a list of standards conformance, see the HP Web site: http://www.hp.com.

Update recommendations

NOTE:

With the introduction of Fabric OS 6.1.1, certain features and functions were removed from Web

Tools (resident in the firmware) and migrated to the Data Center Fabric Manager (DCFM) management

application. HP recommends that, before you upgrade to Fabric OS 6.1.1x or later, if DCFM is not

running on your fabric, you review the Web Tools functionality moved to DCFM, page 30 in these

release notes and take note of what has changed so you can assess the impact on your fabric.

All products supported by Fabric OS 6.0.x can be upgraded to Fabric OS 6.2.0g. If applicable, HP

recommends that you upgrade to Fabric OS 6.2.0g as soon as possible to take advantage of the

latest fixes and features.

it does not support Access Gateway. The same applies to the HP StorageWorks 8/8 and 8/24 SAN

Switches. Both use the same hardware, but only the 8/24, which has all ports licensed, has Access

Gateway support. Also, Access Gateway mode is not supported with the Brocade 4-Gb SAN Switch

for HP p-Class BladeSystem (Brocade 4012) if any half-height BladeServers (BL3xp) are configured

in the same sleeve in the p-Class enclosure. For the latest updates, see the HP website:

http://www.hp.com

Access Gateway connectivity is supported by the switches listed in Access Gateway support and also

by the following B-series switches:

•HP StorageWorks SAN Switch 4/32

•HP StorageWorks SAN Switch 4/32B

•HP StorageWorks SAN Switch 4/64

•HP StorageWorks SAN Director 4/256

•HP StorageWorks SAN Switch 8/80

•HP StorageWorks DC SAN Backbone Director

•HP StorageWorks DC04 SAN Director

•HP StorageWorks 400 Multi-Protocol Router

•HP StorageWorks EVA4400 Embedded Switch Module

Access Gateway was introduced with Fabric OS 5.2.1b. It allows a switch to operate in agmode ,

which allows simplified connectivity between large numbers of servers and the SAN. Access Gateway

leverages N_Port ID Virtualization (NPIV) to hide the complexity of the servers (both physical and

virtual) attached to it, while allowing easy SAN connectivity. The edge fabric switch provides all fabric

services, while Access Gateway connects to the edge switch by what appears as a host bus adapter

(HBA) connection. This architecture allows the deployment of many additional servers without requiring

a domain and the associated fabric rebuild traffic. Rebuild traffic is prevalent when switches are

powered on, added, or removed from a fabric.
