9. The NS388S storage enclosure with dual 12G SAS Expanders (model: NS388S-DE)
supports redundant application that allows two host computers to connect to each
12Gbps SAS Expander module within the Netstor unit at the same time. Therefore,
when one 12G SAS Expander module accidentally fails, the other host computer will
still be able to access the data files stored on the Netstor storage in support of the failover.
The connection diagram for NS388S-DE storage redundant usage is shown as follows:
