in M-EOS fabrics running in McDATA Fabric Mode. M-EOS products in the fabric must be running M-EOS 09.07.00 or later. • M-EOS Open Fabric Mode support-HP supports Interop Mode 3 on Fabric OS 6.1.x with the 4/256 SAN Director & DC SAN Backbone Director. This allows Directors to participate directly in M-EOS fabrics running in Open Fabric Mode. M-EOS products in the fabric must be running M-EOS 09.07.00 or later. Interop Mode 3 scalability limits have also been increased to match those of Interop Mode 2. • Traffic Isolation Zones supported in mixed fabrics in Interop Mode 2-Fabric OS 6.1.x allows the Traffic Isolation Zones capability to be used in fabrics with M-Type products. The M-EOS based products can also provide analogous capability through the use of Preferred Path configurations. • Frame Redirection-Fabric OS 6.1.x allows Frame Redirection to be used on FOS products that are operating in either of the native connectivity modes (Interop Mode 2 or 3). This provides even greater flexibility and support for environments that are interested in using the powerful Frame Redirection capability. Access Gateway Access Gateway enhancements include: • Trunking with Access Gateway-Enables frame distribution across a set of available paths linking Access Gateway to an adjacent switch. The adjacent switch to the Access Gateway has to be an HP StorageWorks switch running Fabric OS 6.1.x or later. This feature also enhances availability by enabling seamless fail-over of traffic from a failed N_Port to other ports within a trunk group. Trunking is an optionally licensed feature. • Advanced Device Security Policy (ADS)-Extends the DCC policy to a switch module in Access Gateway mode. DCC policy support enables a user to restrict N_port logins through an F_port of an Access Gateway. The user must provide a list of device Port WWNs for an F_Port in order to enable those devices to login through that F_port. This policy is also supported for NPIV connections on F_ports. • 16-bit routing enhances interoperability of Access Gateway with Cisco fabrics. This capability only applies to 8Gb platforms. Integrated Routing This new licensed capability allows ports in a DC Director, 8/40 SAN Switch, or 8/80 SAN Switch to be configured as EX_Ports supporting Fibre Channel Routing. This eliminates the need to add an MP Router blade (FR4-18i) or use the 400 MP Router for FCR purposes. Integrated Routing provides double the bandwidth for each FCR connection (when connected to another 8G-capable port). Traffic Isolation zones over FCR This enhancement enables traffic isolation across EX ports and VEX ports. This benefits applications like Tape Pipelining and Fast Write that traverse VE ports where customers want to control the exact path and ports that are used. Port Mirroring Fabric OS 6.1.x adds support for Port Mirroring to 8Gb ports. The Port Mirroring feature mirrors traffic in both directions between a source and destination ID pair to a single mirror port. The user may connect an FC analyzer to this mirror port to capture all the mirrored traffic and perform troubleshooting or other analysis. Buffer credit recovery Fabric OS 6.1.x implements credit recovery protocol as described in FC-FS standards. This feature is supported only on E-ports and allows switches to automatically recover buffer credits that were accidentally "lost" over time. Buffer credit recovery prevents link performance degradation that can otherwise occur due to loss of credits over time. HP StorageWorks Fabric OS 6.1.0c release notes 7
