EonStor S12S-R/G1032 Installation and Hardware Reference Manual
Expansion Links:
The “
Exp.
” port connects to expansion enclosures, e.g., Infortrend’s
S12S-J1002R or S12S-J1002S. For a dual-controller subsystem,
each expansion port connects a RAID controller to a corresponding
JBOD controller making fault-tolerant links for distinguished SAS
domains. Although the single-controller S12S models come with a
single RAID controller, it is still highly feasible to create fault-tolerant
cable links to application servers as shown in the following
discussion.

The maximum number of expansion enclosures for the combination
of dual-controller RAID and JBODs is 3.
