system can identify alternate paths to the same logical
drive.
RAID configuration
Remote replication functionality is not supported
using this configuration. For remote replication
setup, please refer to page 72 "High Availability IP
SAN (Remote Replication Enabled) or page 74 "High
Availability IP SAN with Port Trunk (Remote
Replication Enabled).
4 logical drives (each has 4 member drives; for better
performance, you can include drives from JBOD)
LD0 mapped to CH0 AID and CH0 BID; LD assigned to
controller A
LD1 mapped to CH1 AID and CH1 BID; LD assigned to
controller A
LD2 mapped to CH2 AID and CH2 BID; LD assigned to
controller B
LD3 mapped to CH3 AID and CH3 BID; LD assigned to
controller B
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.
