Description

RAID system

Single-Controller 4-port iSCSI RAID

HBA or NIC

iSCSI initiators, preferably PCI-E TCP/IP offload engine

(TOE) capable 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

multipath software so that your operating system can

identify alternate paths to the same logical drive.
