Fibre Channel connections between SAN Volume Controller and the switch can
be up to 100 m using the standard small form-factor pluggable (SFP)
transceivers that are provided by SAN Volume Controller. Connections of up to
10,000 m are supported through longwave SFP transceivers. The supported
longwave SFP transceivers are available to order from IBM.

1. Is the 100 m figure correct?
2. If not, how can I submit documentation feedback so that this gets fixed?
I left a comment on the document download page (http://www-01.ibm.com/support/docview.wss?uid=ssg1S7003981) but I don't know what happens to those comments.
