1 Gbps Fibre Channel/FICON is mapped into:
–
STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-18c, STS-24c, STS-48c
–
VC4-1c, VC4-2c, VC4-3c, VC4-4c, VC4-6c, VC4-8c, VC4-16c
–
STS-1-Xv where X is 1 to 24

2 Gbps Fibre Channel/FICON is mapped into:
–
STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-18c, STS-24c, STS-36c, STS-48c
–
VC4-1c, VC4-2c, VC4-3c, VC4-4c, VC4-6c, VC4-8c, VC4-12c, VC4-16c
–
STS-1-Xv where X is 1 to 48

6.2.2.2 SW -LCAS
VCAT group (VCG) is reconfigurable when the software link capacity adjustment scheme (SW-LCAS)
is enabled, as follows:
• Out-of-service (OOS) and out-of-group (OOG) members can be removed from VCG
• Members with deleted cross-connects can be removed from VCGs
• Errored members can be autonomously removed from VCGs
• 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)
6.2.2.3 Distance Extension
This following list describes the FC_MR-4 card distance extension capabilities:
• Enabling of a storage access networking (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)
