Fibre Channel Switch Notes
The Fibre Channel switches that can be connected depend on the connection configuration that is used (the
OS and the ETERNUS DX/AF). Refer to the "Server Support Matrix for FC-SWITCH" before starting.
When a Fibre Channel switch (ETERNUS SN200 series, Brocade series) is to be used between the server and
ETERNUS DX/AF, follow the preparation-in-advance and Fibre Channel switch setup procedures given in the
"Configuration Guide -Server Connection- (Fibre Channel) Fibre Channel Switch Settings".
If AIX server is connected to a Fibre Channel switch, the Fibre Channel switch port link speed must be set.
•
Set the link speed of the Fibre Channel switch ports according to the link speeds of the server-side Fibre
Channel cards, as follows:
Combination of devices
Maximum link speed of Fibre Channel
card
16Gbit/s
8Gbit/s
4Gbit/s
2Gbit/s
If the devices being connected together both have automatically set link speeds, the resulting link speed
may be less than optimal. The default link speed setting for Fibre Channel switch ports is "Automatic". The
link speed setting of a true IBM Fibre Channel card cannot be changed to other than "Automatic", so the
Fibre Channel switch port link speeds must be fixed to match the actual speed of the server-side Fibre
Channel cards, as per the above table, so that the same link speed is always used.
