Single Controller with Fault-Tolerant Path

Component

Description

Storage system

Single controller with 4 host ports

HBA or NIC

iSCSI initiators, preferably PCIe TOE (TCP/IP offload engine)-capable

cards

GbE cables

GbE network cables

Software

MPIO to manage the fault-tolerant paths with failover/failback and load

balance capabilities.

RAID configuration

•

Four logical partitions (created from two logical volumes)

•

Two logical volumes (each contains a logical drive)

•

Two logical drives

NOTE:

Each logical partition appears on two different host links for

fault tolerance. Use MPIO software so that your operating system

can identify the alternate paths to the same logical drive.
