D-XTR-MN-A-24 Exam Dumps : Dell XtremIO Maintenance Achievement

To successfully operate Technician Advisor on an XtremIO X2, TCP ports 80 and 443 need to be open between the XMS (XtremIO Management Server) and X1-SC1 (Storage Controller). These ports are used for HTTP and HTTPS communication, respectively, allowing for secure management and operation of the storage system.

The show-storage-controllers command is used in XMCLI to verify the IP addresses of the Storage Controllers after they have been changed. This command provides detailed information about the status and configuration of the storage controllers, including their IP addresses.

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.
