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.
