failover/failback and load balance. Use EonPath
multi-pathing software so that your operating system can
identify alternate paths to the same logical drive.
RAID configuration 2 logical drives (each has 8 member drives). More
logical drives can be created from drives in JBOD.
LD0 mapped to CH0 AID, CH1 BID, CH2 AID and CH3
BID; LD has to be assigned to both controllers A and
B to enable remote replication
LD1 mapped to CH1 BID, CH0 AID CH3 BID and CH2
AID; LD has to be assigned to both controllers A and
B to enable remote replication
NOTE
In the event of single controller failure, a logical drive is accessed through the host
IDs managed by the alternate RAID controller. Host IDs and port IPs do not fail-over
to the surviving controller. Therefore, the EonPath multi-pathing driver is necessary
for path redundancy and controller failover.
