When comparing XtremlO X1 to XtremlO X2, how much memory is installed in a Storage Controller that has a DAE attached with 400 GB SSDs?
Answer : B
When comparing XtremIO X1 to XtremIO X2, the amount of memory installed in a Storage Controller with a DAE attached with 400 GB SSDs differs. For the X1, it is 256 GB, while for the X2, it is 512 GB. This increase in memory in the X2 model supports higher performance and improved handling of data operations.
In an XtremIO X2, what is the maximum number of lifetime cycles for NVRAM?
Answer : D
In an XtremIO X2 system, the maximum number of lifetime cycles for NVRAM is 10,000. This number represents the total count of write and erase cycles the NVRAM can endure throughout its lifespan, ensuring data integrity and reliability over time.
Why is an extra rack unit space used between X-Bricks when installing a multi X-Brick XtremIO X2?
Answer : B
An extra rack unit space is used between X-Bricks when installing a multi X-Brick XtremIO X2 to accommodate the cable management duct. This space is essential for organizing and managing the cables, ensuring proper airflow, and making maintenance tasks easier.
How many expansions are required to expand a Starter X-Brick cluster to an eight X-Brick cluster?
Answer : D
To expand a Starter X-Brick cluster (which typically begins with one X-Brick) to an eight X-Brick cluster, a total of three expansions are required. Each expansion step in XtremIO can typically double the number of X-Bricks, thus:
First expansion: From 1 X-Brick to 2 X-Bricks.
Second expansion: From 2 X-Bricks to 4 X-Bricks.
Third expansion: From 4 X-Bricks to 8 X-Bricks.
This sequence ensures that the storage array scales properly, maintaining performance and redundancy.
What is indicated when the XtremIO X2 NVRAM status LED is flashing red at one second intervals?
Answer : D
The steps to address this issue usually involve:
Investigating the system logs to identify the specific nature of the error.
Contacting Dell EMC support for guidance on diagnosing and resolving the issue.
Following the recommended procedures for troubleshooting or replacing the affected NVRAM module, as per the support team's instructions.
=========================
In addition to the cluster name, which parameters are required for creation of the cluster?
Answer : C
When creating a cluster, in addition to the cluster name, the following parameters are required: the expected number of X-Bricks, the IP address of X1-SC1 (the first Storage Controller), and the package name. These parameters are essential for setting up the cluster configuration and ensuring proper communication between components.
What is the minimum XtremlO software version required for expanding a Starter X-Brick cluster?
Answer : C
The minimum XtremIO software version required for expanding a Starter X-Brick cluster is 4.0.4. This version includes the necessary features and improvements to support the expansion process, ensuring compatibility and optimal performance.
