Theory of Controller
Operation
In this Appendix
This chapter provides a functional overview and understanding of
the supported topologies and operating modes for the
DuraStor 6320SS and 7320SS storage subsystems. With this
information, you will be able to make the best choice based on the
supported topologies, to set up your storage solution.
The DuraStor 6200S and 7200S RAID controllers can be set up to
operate in one of three different modes:
■
Stand-alone
■
Active-active
■
Active-passive
These provide a configuration that includes different host
connections, disk channel connections, internal hub configurations,
single or dual RAID controllers, and whether the controllers are
operating in single or dual port modes.
