Up to 300 km
Optical 2 Gb/sec ISLs extended through Cisco 2 Gb/sec CWDM optics
Up to 100 km
Optical 4 Gb/sec ISLs extended through Cisco 4 Gb/sec CWDM optics
Up to 40 km
Optical 10 Gb/sec ISLs extended through Cisco Extended Reach optics
Up to 40 km
DWDM optics installed in MDS series switches and directors may be used
for 2 Gb/sec links

Up to 300 km
DWDM optics installed in 9200/9500 series switches and directors may be
used for 10 Gb/sec links
used for 10 Gb/sec links
Up to 100 km
Note: 8 Gb/sec ISLs were not tested at extended distance through CWDM or DWDM due to no availability of extension equipment with an 8
Gb/sec interface – When equipment is available this will be tested.
Table 7) Supported Software
It is anticipated that the tested switches and directors will operate with supported versions of System z operating systems - z/OS, z/VM, z/VSE,
z/TPF, and Linux on System z that support FICON.

Notes:
1.
FCIP distance support is for up to 300 km. Testing was performed with both emulated distance and with real fiber over DWDM.
2.
Performance characteristics can vary depending on environment. Professional assistance should be sought when implementing this technology.
3.
The 14+2 and the 18+4 port cards can be plugged into the MDS-9500 directors.
4.
Contact Cisco for further extending FCIP links through use of the FICON XRC Acceleration (XRCA) feature.
5.
Contact Cisco for further extending FCIP links through use of the FICON Tape Acceleration (FTA) for tape writes feature.
