Infortrend EonStor DS S16E-R2142 - Switched Fabric Connection (Dual-Controller)

EonStor DS S12/S16/S24 Series Hardware Manual
If a server ha
s multiple data paths to a RAID system, a multi-path software is
necessary, e.g., Infortrend’s EonPath driver.
The two logical drives in the above drawing cannot leverage the full computer power
of the system. You may attach 1 or 2 more JBODs to acquire more end-to-end
performance
3.2.6 Switched Fabric Connection (Dual-Controller)
NOTE
A logical partition presented through LUN Mapping can be seen by all servers across
SAN. Make sure you have access control such as file-locking, switch zoning, port
binding, etc., to avoid access contention.
