Chapter 6 Storage Access Networking Cards
6.2.2 Enhanced Card Mode
6.2.2 Enhanced Card Mode
Features available in enhanced card mode are given in this section.
6.2.2.1 Mapping
1 Gbps Fibre Channel/FICON is mapped into:
• SONET CCAT: STS1c, STS3c, STS6c, STS9c, STS12c, STS18c, STS24c, STS48c
• SONET VCAT: STS3c-Nv (N is 1 to 8), STS1c-Nv (N is 1 to 24)
• SDH CCAT: VC4-1c, VC4-2c, VC4-3c, VC4-4c, VC4-6c, VC4-8c, VC4-16c
• SDH VCAT: VC4-Nv (N is 1 to 8)
2 Gbps Fibre Channel/FICON is mapped into:
• SONET CCAT: STS1c, STS3c, STS6c, STS9c, STS12c, STS18c, STS24c, STS36c, STS48c
• SONET VCAT: STS3c-Nv (N is 1 to 16), STS1c-Nv (N is 1 to 48)
• SDH CCAT: VC4-1c, VC4-2c, VC4-3c, VC4-4c, VC4-6c, VC4-8c, VC4-12c, VC4-16c
• SDH VCAT: VC4-16v (N is 1 to 16)
6.2.2.2 SW-LCAS
Virtual Concatenation Group (VCG) is reconfigurable with the software link capacity adjustment
scheme (SW-LCAS) enabled, as follows:
• Out of service and out of group members can be removed from VCG
• Members with deleted cross connect can be removed from VCG
• Errored members can be autonomously removed from VCG
• Degraded bandwidth VCGs are supported
• VCG is flexible with SW-LCAS enabled (VCG can run traffic as soon as the first cross-connect is
provisioned on both sides of the transport)
6.2.3 Distance Extension (Enhanced Mode Only)
This following list describes FC_MR-4 card distance extension capabilities.
• Enabling of SAN extension over long distances through buffer-to-buffer (B2B) credit spoofing.
–
2300 Km for 1G ports (longer distances supported with lesser throughput)
–
1150 Km for 2G ports (longer distances supported with lesser throughput)
• Negotiation mechanism to identify if far end FC-over-SONET card supports Cisco proprietary B2B
mechanism.
• Auto detection of FC switch B2B credits from FC-SW standards-based ELP frames.
• Support for manual provisioning of credits based on FC switch credits.
• Automatic GFP buffer adjustment based on roundtrip latency between two SL ports.
• Automatic credit recovery during SONET switchovers/failures.
