1.4.5.3. MUX Transition Cards

SATA disk drives require an Active/Active (A/A) MUX transition card,

sometimes referred to as a dongle. The MUX transition card is in-

stalled on the SATA disk drive interface and provide a specialized

interface to the drive plane. The Active/Active MUX transition card

allows both controllers to see the drive at the same time, therefore

there is no concept of ownership, normally a behavior of SATA disk

drives (Fig. 19).

1.4.5.4. Dummy Carrier Modules

Dummy Carrier modules are provided for ﬁlling all unused drive

slots (Fig. 20). They are designed as integral drive module front cap

and must be installed to maintain a balanced airﬂow.

The dummy carrier modules plug into the empty drive bay by push-

ing them into place.
