Flexible front-end director installation
The maximum number of FEDs that can be installed in the controller depends on the
number of VSD pairs and back-end directors (BED) that are also installed.
As shown in the following gure, the controller is built with 12 I/O slots, eight of which
ar
e dual-purpose. This pr
o
vides a wide r
ange of conguration exibility.
Note: Each fr
ont-end dir
ector
and
back-end director consists of a set of two
blades, as indicated by the numbers in the gure. A VSD pair, however, uses a
single slot, but is sold and installed in pairs.
The following list describes the purpose of the slots.
■
Eight of the 12 I/O slots support dierent types of devices.
■
Slots 1C/2C and 1D/2D are reserved for the rst two front-end directors.
