Multi-Port Mirrored Dual Host System-Quad Connection

Multi-Port Mirrored Dual Host System-Quad Connection

This topology provides one of the more robust active-active RAID storage solution for
dual host systems with dual fibre ports. It has the following advantages: high availability
and high-performance where each host requires access to all logical drives (LUNs),
redundant active-active Wahoo2 RAID Controllers, transparent failover and failback, and
shared storage between two host systems.

Its disadvantages are the requirement for dual ported HBA’s and multiple cables.

Duplex Mode Logical View - Multi-Port Mirrored Dual Host System-Quad Connection

In this topology the Host I/O card switch 1, 2, and 6 are set to the “Up” position.

Switch 1 sets the bus speed mode on the Host I/O card to 2 GB/sec.

Switch 2 configures the enclosure for the Wahoo2 RAID Controller.

Switch 6 enables automatic internal hub failover during a controller failure.
