Daisy-Chaining
Recognizing the typical insignificance of the performance variance
between the “Fan-Out” and “Daisy-Chaining” configurations, the primary
reason for using this one would be limitations on physical space. This
could be the number of available slots on the host computer
motherboard, or a lack of desk or rack space.
In the daisy-chain configuration, successive PCIe expansion systems
are added to the "end" of the PCIe expansion hierarchy, which adds
"depth" to the Local Bus by increasing the number of the logical PCI
levels active in the system configuration.
Verify your configuration
Before you start installing your PCI cards (refer to Chapter 4 Install
Cards and Drives for more information), you should confirm that
everything is in proper working order. Refer to
Chapter 3 Verify
Installation for guidance in verifying the proper installation of your
Expansion System.
NOTE
Notice that each Daisy-Chained unit appears in the Device Manager
in the reverse order of its place in the configuration.
