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 6-1)
■ Direct connection from two data host servers (FIGURE 6-2)
■ Data host connection through Fiber Channel switch fabric (FIGURE 6-3)
■ Mixed connection, direct and through switch (FIGURE 6-4)
