MSA Hub 2/3
The MSA Hub 2/3 is an optional input/output device designed to replace the
single port Fibre Channel I/O Module that comes standard with the MSA1000.
This option is designed to provide an inexpensive and easy way for a clustered
pair of servers to access the storage controller (using the arbitrated loop
configuration) without having to buy an external hub or switch. Two SFP ports are
presented to the user while internally a third port accesses the controller.
If a second controller is added for additional functionality, an MSA SAN Switch
2/8 or an MSA Hub 2/3 may be installed.
If you are using the MSA Hub 2/3 and an additional controller is installed for
redundancy, a second MSA Hub 2/3 must be ordered and installed. In redundant
configurations, the interconnect devices must be a matching pair.
