7.4.3. SAN Topologies & Interoperability
The SilkWorm 2040 is a fabric switch, which can be interconnected with other Brocade fabric
switches (such as SilkWorm II, SilkWorm Express, SilkWorm 2000 series), regardless of the supplier
of the switch (Bull or other Brocade reseller). The switch has a single E-port.
The switch has been qualified for the point-to-point connection of
•
Escala servers
•
DAS and Symmetrix disk subsystems
•
Crossroads FC/SCSI bridges (model 4100 and 4200)
The SWL GBIC supports 500 m cables with 50 µm multi-mode optical fibers.
The LWL GBIC supports 10 km cables with 9 µm single mode optical fibers.
Any kind of device can be connected and mixed on the switch, provided that they are supported by
Bull or by a third party supplier.
