Switchless Configurations

In a switchless configuration (Sun StorEdge 3900SL, 6910SL, or 6960SL series system) you can upgrade the switches that are connected to the Solaris server to the Sun StorEdge SAN 4.1 Release firmware. For a list of the supported switches visit the http://www.sun.com web site.

Direct attachment to the StorEdge 3900 and 6900 Series arrays with 1 Gbit or 2 Gbit HBAs require no changes.

Before making any changes to the Sun StorEdge 3900 or 6900 series, you must have a Sun StorEdge SAN 4.1 infrastructure already in place and functional. This includes at a minimum:

■A Solaris host on the SAN management network loaded with SANbox2 Manager.

■Sun StorEdge 2 Gbit 16-port switch network configured in desired topology (ring, star, mesh, or cascade) with healthy ISL links.

Note –Whereas 1 Gbit switch port numbers are numbered starting with 1 (one), 2 Gbit switch port numbers are numbered starting with 0 (zero).
