4.1.8 Sample Topology – Data Sharing

In the configuration shown in Figure 4-3, many servers share one (1) subsystem over the

Fibre Channel network. Data path redundancy makes sense when the following

configurations are available:

1. HA access software control is available or that each storage volume is

exclusively accessed through one ID/LUN on a host port.

2. Multiple storage volumes can each be optimized for a different kind of I/O

demands. Logical drive stripe size and write policy can separately be configured

3. Multiple Storage volumes are presented on either of the host ports. The host

management software should direct the data flow through a surviving path in the

event of single path failure.

♦ Connections: The input ports on the subsystem, FC-CH0 and FC-CH1, are

connected to a FC switch and then to HBAs on host computers.
