Dell EMC D-XTR-MN-A-24 Exam - Topic 2 Question 3 Discussion

Actual exam question for Dell EMC's D-XTR-MN-A-24 exam

Question #: 3
Topic #: 2

A multi X-Brick XtremlO X1 cluster is being installed. How many BBU connections, and of which type, are required per X-Brick?

A2 BBUs providing protective power to the Storage Controllers
1 BBU COM port connected to the bottom Storage Controller

B1 BBU providing protective power to the bottom Storage Controller
2 BBU COM ports; one connected to each Storage Controller

C1 BBU providing protective power to the Storage Controllers
2 BBU COM ports; one connected to each Storage Controller

D2 BBUs providing protective power to X-Brick 1 and 2 Storage Controllers only
4 BBU COM ports connected to each Storage Controller

Show Suggested Answer

Suggested Answer: C

For a multi X-Brick XtremIO X1 cluster, each X-Brick requires one Battery Backup Unit (BBU) that provides protective power to both Storage Controllers within the X-Brick. Additionally, there are two BBU COM (communication) ports required, with one connected to each Storage Controller. This configuration ensures that in the event of a power failure, the BBU can maintain power to the Storage Controllers, allowing them to safely shut down and protect data integrity1.

The installation process would typically involve:

Installing the BBU in the designated slot within the X-Brick.

Connecting the BBU power cable to the power supply of both Storage Controllers.

Connecting a BBU COM port to each Storage Controller for communication and monitoring purposes.

This setup is crucial for maintaining the high availability and data protection standards that XtremIO systems are known for1.

Really? I thought we only needed 1 BBU for the whole setup!

Wait, 4 COM ports? That seems excessive!

I remember something about needing 2 COM ports, but I can't recall if it's one for each controller or something else.

Based on my understanding, the correct answer is option C. The X-Brick requires 1 BBU providing protective power, and 2 BBU COM ports connected to the Storage Controllers.

I'm a bit confused by the different options. I'll need to carefully read through each one and consider the specifics of the X-Brick configuration.

Okay, let me think this through step-by-step. The key information I need to focus on is the number and type of BBU connections required per X-Brick.

Okay, I think I've got this. The key is to select the line before the "Room Cleaning" heading, then either go to the Insert tab and select Page Break, or just press Ctrl+Enter. Simple enough!

I wonder if the exam writers were feeling a little 'X-treme' when they came up with this question. Maybe they were listening to some 'Xtreme' music while writing it.

I think the answer is C. It makes the most sense to have 1 BBU providing protective power to all the Storage Controllers, and 2 BBU COM ports to connect to each one.
