EonStor DS S12/S16/S24 Series Hardware Manual
Example 3: In a multiple host scenario (Host 0, Host 1, Host 2 and Host 3), users
can create four LDs (LD 0, LD 1, LD 2 and LD 3) and map the LDs via a channel
(channel 0 or channel 1) up to four Host support.
As shown below LD 0 > Ch 0 (Host 1), LD 1 > Ch 1 (Host 2), LD 2 > Ch 0 (Host 3)
and LD 3 > Ch 1 (Host 4).

Multi-path I/O is required at each Host HBA

LD 0 should only be mapped to Host 0 through Channel 0. In this case, Host
1, 2 and 3 can also see LD0 but requires LUN filtering.
