High Availability IP SAN with Port Trunk (Remote Replication-enabled)
Component
Description
Storage system
Redundant controllers with eight host ports
HBA
iSCSI initiators, preferably PCIe TOE (TCP/IP offload engine)-capable
cards
GbE cables
GbE network cables; port trunking marked in orange rectangles
GbE switch
Ports divided into 2 virtual LANs. Both controllers are linked to both
virtual LAN zones.
Software
MPIO to manage the fault-tolerant paths with failover/failback and load
balance capabilities. Use MPIO multipathing software for the operating
system to identify the alternative paths to the same logical drive.
RAID configuration
•
Two logical drives; each has eight member drives. You can create
more logical drives from the drives in the expansion systems.
•
LD0 mapped to CH0 AID, CH1 BID. LD must be assigned to
controllers A and B to enable remote replication.
•
LD1 mapped to CH1 BID, CH0 AID. LD must be assigned to
controllers A and B to enable remote replication.
