Advanced Diagnostics Support on 16 Gbps FC Platforms • D_Port support Fabric OS 7.0.0a introduces the concept of the Diagnostic port or D_Port. The D_Port feature allows diagnosis of components associated with a link, such as SFPs and cables. This test performs connectivity checks between various components on the ISL, drives link saturation and measures link distance. This feature is supported on ISLs between 16 Gbps FC platforms using 16 Gbps SFP+ transceivers. • Forward Error Correction (FEC) The FEC feature allows recovery of error bits in a 10 Gbps or a 16 Gbps data stream. It can correct up to 11 error bits in every 2112-bit transmission. This feature is enabled by default on all ISLs of 16 Gbps FC platforms. • Real-time Power Monitoring The new 16 Gbps blades (HP SN8000B 16 Gbps 32-port or 48-port Fibre Channel Blades and the Core blades) support real-time measurement of power being consumed by those blades. The real-time power consumption of 16 Gbps blades can be displayed using the chassisshow command. • Advanced SFP Monitoring Fabric Watch has been enhanced to monitor 16 Gbps SFP+, 10 Gbps SFP+ and 16 Gbps QSFP. It also allows thresholds to be configured based on the type of the SFP. Dynamic Fabric Provisioning - Fabric Assigned WWN To simplify and accelerate server deployment and improve operational efficiency, Fabric OS 7.0.0a now supports Fabric Assigned WWN or FA-WWN, which uses a virtual WWN for a server instead of the server's physical PWWN to create zoning and LUN mapping/masking. Once the server is attached to the SAN, this feature allows the fabric to assign this virtual WWN to the server. This features requires servers to be using Brocade HBAs/Adapters with HBA driver version to be released in the future. Also, configuration is required at the HBA to utilize FA-WWN. FCIP Enhancements Fabric OS 7.0.0a implements the following FCIP enhancements: • 10 GigE lossless failover on HP DC SAN Director Multiprotocol Extension Blade The 10 GigE lossless failover feature allows users to configure a new set of IP addresses and allow a tunnel to failover to the secondary 10 GigE port. There are two types of configurations that are supported: active/active and active/passive. In the active/active case, the data is sent on both 10 GigE ports, thus load-balanced across 10 GigE ports. In active/passive case, the data is failed-over to a passive circuit (one with a higher metric) if all active circuit paths fail. This feature is supported on HP DC SAN Director Multiprotocol Extension Blade only in 10 Gbps mode. • Multi-Gigabit circuits on HP DC SAN Director Multiprotocol Extension Blade, which allows more than 1 Gbps to be configured on a single FCIP Circuit The Multi-Gigabit Circuit implementation has the following capabilities: • Support for circuits with a rate configured at more than 1 Gbps HP B-series Fabric OS 7.0.0a Release Notes 7
