Figure 5-4A DAS Configuration With Four Servers, a Dual-Controller SANnet II 200 SATA Array, and Two Expansion Units

Establishing complete redundancy and maintaining high availability requires the use of multipathing software such as SANpath software. To configure for multipathing:

1.Establish two connections between each server and the array.

2.Install and enable multipathing software on the server.

3.Map the logical drive each server is using to the controller channels that the server is connected to.

Set up an IP address for the controller 5.1.1 Point-to-Point Configuration Guidelines Caution - If you keep the default loop mode and connect to a fabric switch, the array automatically shifts to public loop mode. As a result, communication between the array and the switched fabric runs in half duplex send or receive instead of providing the full duplex send and receive performance of point-to-point mode 5.1.2 A Sample SAN Point-to-Point Configuration Remember these important rules Map LG1 to SIDs 45 and Note - These illustrations show the default controller locations however, the primary controller and secondary controller locations can occur in either slot and depend on controller resets and controller replacement operations 2.
