34 Compaq StorageWorks Data Replication Manager HSG80 ACS Version 8.5P Operations Guide
Before you connect the fiber optic cables, Compaq recommends that you tag each end of
the cables with the following information:
Host-to-Switch Connections
Rank number or PCI slot number of the host bus adapter
Port number on switch
Switch-to-Controller Connections
Fibre Channel switch name (top or bottom)
Fibre Channel switch port number (0-15)
Site name (initiator or target)
Controller name
Controller port number (1 and 2)
Host port number
Host Bus Adapter worldwide name
The DT solution requires two different types of fiber optic cables, depending on where the
connections are made. Cabling at each individual site that involves the controller, the
switch, and the host is made with 50 micron multi-mode fiber optic cables. The maximum
length that these cables will support is 500 meters. When cabling between initiator and
target sites that are more than 500 meters apart and using GBIC, you must use a 9 micron
single-mode fiber optic cable, which can run a distance of up to 10 kilometers.
NOTE: The 9-micron single mode fiber optic cable may also be referenced by some
manufacturers as an 8.3-micron cable. In addition, to increase the reliability of the cable or to
reduce the likelihood of having to re-pull or re-install the cable over a long distance, it is
recommended that multiple conductor cable be used.
Data Replication Manager uses other long distance transport modes. For connection
