Description

RAID system

iSCSI RAID managed by a single controller, with 4 host

ports

HBA or NIC

iSCSI initiators, preferably PCI-E TOE cards

GbE cables

GbE network cables

Software

EonPath to manage the fault-tolerant paths with

failover/failback and load balance

RAID configuration

4 logical partitions (created from 2 logical volumes)

2 Logical Volumes (each contains a logical drive)

2 Logical Drives

* Each logical partition appears on two different host

links for the purpose of fault tolerance. Use EonPath

multi-pathing software so that your operating system can

identify alternate paths to the same logical drive.
