A multi X-Brick XtremlO X1 cluster is being installed. How many BBU connections, and of which type, are required per X-Brick?
- A. 1 BBU providing protective power to the bottom Storage Controller
2 BBU COM ports; one connected to each Storage Controller - B. 2 BBUs providing protective power to the Storage Controllers
1 BBU COM port connected to the bottom Storage Controller - C. 1 BBU providing protective power to the Storage Controllers
2 BBU COM ports; one connected to each Storage Controller - D. 2 BBUs providing protective power to X-Brick 1 and 2 Storage Controllers only
4 BBU COM ports connected to each Storage Controller
Answer: C
Explanation:
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.

NEW QUESTION # 29
In a multi X-brick cluster, what happens when both DAE Controllers in a single X-Brick fail?
- A. Cluster performance is degraded
- B. Entire cluster shuts down
- C. Cluster operations continue normally
- D. Only LUNs with data on that DAE go offline
Answer: D
Explanation:
In a multi X-brick cluster, each X-brick consists of multiple Disk Array Enclosures (DAEs) that work together to provide storage and data redundancy.
If both DAE controllers in a single X-Brick fail, the impact is localized to the LUNs (Logical Unit Numbers) that store data on that particular DAE.
The entire cluster does not shut down; rather, only the data on the affected DAE becomes unavailable.
This design ensures that the rest of the cluster continues to operate normally, albeit with potential performance degradation depending on the data distribution and workload.
