Question #: 3
Topic #: 2

[All Dell XtremIO Maintenance Achievement Questions]

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.

Alright, time to put on my 'BBU-tinizer' hat and really analyze this problem. I've got a hunch C is the way to go.

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 agree, it seems like they were trying to make it sound 'X-treme' for no reason.

I think they were trying to make it sound more complicated than it actually is.

Hmm, I'm stuck between B and C. I'll go with C, just to be safe. Can't go wrong with the middle option, right?

D looks good to me. Redundancy is key, so having 2 BBUs and 4 COM ports is the way to go.

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.
