NEW QUESTION 19
To which bus is the Dell EMC Unity 880F DPE connected?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
The DPE on 480/F, 680/F, and 880/F systems is internally connected to Bus 99 which is a separate bus than the first SAS expansion port that is connected to Bus 0. Therefore, the DPE is recognized by the system as Bus 99 Enclosure 0 while the first DAE connected to the first SAS expansion port would be Bus 0 Enclosure 0. This is different than X00/F, X50F, and 380/F systems. Furthermore, this means that the twenty-five drives in front of the DPE for 480/F, 680/F, and 880/F systems are internally recognized as Bus 99 Enclosure 0 Drive 0 - Bus 99 Enclosure 0 Drive 24. In Unisphere, the drives are seen DPE Drive 0 -DPE Drive 24
