Sun Microsystems 2500 manual Array Data Host Connection Topologies

Note – For maximum hardware redundancy, you must install a minimum of two HBAs in each host. Dual-port HBAs give you two paths into the storage array but do not ensure redundancy if the HBA fails.

2540 Array Data Host Connection Topologies

You can connect data hosts to access the Sun StorageTek 2540 Array directly to the array, or through Fibre Channel (FC) switches to the array. The following figures illustrate four possible host connection topologies for the 2540 Array:

■Direct connection from a single data host server (FIGURE 3-2)

■Direct connection from two data host servers (FIGURE 3-3)

■Data host connection through Fiber Channel switch fabric (FIGURE 3-4)

■Mixed connection, direct and through switch (FIGURE 3-5)
