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.
