Component Description
SAN storage system Single-controller with 4 host ports
HBA or NIC
iSCSI initiators, preferably PCIe TCP/IP ofoad engine (TOE)-capable
cards
GbE cables GbE network cables
Software
MPIO to manage the fault-tolerant paths with failover/failback and load
balance capabilities.
RAID conguration
• Four logical partitions (created from two logical volumes)
• Two logical volumes (each contains a logical drive)
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.
