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

Show Suggested Answer Hide 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.

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.
