442 IBM System Storage DS3000: Introduction and Implementation Guide
19.1 Cabling and zoning
In 3.5, “Host attachment” on page 36 we discussed the most common host cabling scenarios
for Fibre Channel. In this sample configuration we use a Blade as the host technology. We
use two FC Switches in the BladeCenter®, to provide redundant attachment between the
Blades and the DS3400. Our topology, even though we are using a BladeCenter, is as shown
in Figure 3-9 on page 41. The Blade has one dual port HBA installed. Each HBA port is
connected to one of the BladeCenter switches. One switch is connected to Controller A of the
DS3400, and the other switch is connected to Controller B. The two FC switches are not
interlinked. Figure 19-1 shows our specific configuration. Figure 19-2 shows the FC
connections in the BladeCenter.
