International Business Machines Corporation (IBM) and Cisco Systems, Inc. have successfully completed connectivity testing of the Cisco MDS
family of switches (9216, 9134, and 9222i) and directors (9506, 9509, and 9513) in IBM System z server environments with Cisco NX-OS
4.1(1c) and Cisco Fabric Manager 4.1. This release contains support for the initial release of the 24 port, 48 port, and 4/44 port 8 Gb/sec port
blades.

It is anticipated that the Cisco switches and directors could attach to any System z FICON supported device and other FICON devices that
adhere to the FICON architecture.

∗
It is also anticipated that the Cisco switches and directors will operate with System z and operating systems such as z/OS V1.7 and later,
System Automation for OS/390 (SA OS/390), z/VM, z/VSE, and z/TPF that currently support FICON and FCP.

∗
Fibre Channel over IP at distances up to 300 km (performance characteristics can vary depending on environment)
∗
FICON Tape Acceleration with compression and encryption over FCIP links up to distances of 3000 km for supported devices.
∗
Optical (2, 4, and 10 Gb/sec InterSwitch Links (ISLs) extended up to 300 km through supported extension products – 8 Gb/sec ISLs were
not extended due to availability of extension equipment for 8 Gb/sec traffic

∗
Optical 2 Gb/sec ISLs extended up to 100 km through Cisco extended long wave CWDM optics
∗
Optical 4 Gb/sec ISLs extended up to 40 km through Cisco extended long wave CWDM optics
∗
DWDM optic installed in MDS series switches and directors may be used for 2 Gb/sec links up to 300 km
∗
DWDM optic installed in 9200/9500 series switches and directors may be used for 10 Gb/sec links up to 100 km
Notes:
1)
1)
Machine environments mentioned previously should be at the latest release patch levels as of December 1, 2008.
2)
Cascading of directors and switches is limited to one hop for a FICON environment
3)
Testing was completed on Cisco NX-OS 4.1.1c with Cisco Fabric Manager 4.1

Deployment and Design Considerations:
o
FICON Tape Pipelining over FCIP was not tested – refer to IBM storage compatibility for current status.
o
8 Gb/sec ports were only tested as ISLs (no host or device attachment is available). All host and I/O device attachment was done on 4
Gb/sec interfaces.
Gb/sec interfaces.
o
The preferred method of connection for 8 Gb/sec short wavelength (SX) small form factor pluggable optics (SFPs) is through 50 micron
multimode fiber optic cabling rated at 2000 MHz-km (OM3 fiber). Other 50 micron and 62.5 micron multimode fiber may be used as an
alternative, but distance limitations may exist.
