New feature descriptions This section describes the new features that were introduced in Fabric OS 6.2.0a, and brought forward with Fabric OS 6.2.0d. 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 HP StorageWorks 400 Multi-protocol Router allows a management station to communicate with a remote 400 Multi-protocol Router through the GE ports. This allows a single management station located on the WAN side of the 400 Multi-protocol 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 6.2.0d release notes 5
