Storage Administrator D-XTR-DY-A-24 Book

The RESTful API method used to retrieve an existing configuration from an XtremIO system is the HTTP GET methD. This is a standard method used in RESTful APIs for retrieving resources. In the context of XtremIO, the GET method would be used to call endpoints that return information about the system’s configuration. For example, a GET request to /api/json/v2/types/clusters would retrieve information about the clusters1. The Official Dell XtremIO Deploy Achievement document will contain specific details on the API calls and should be referred to for the most accurate instructions.

Understanding XtremIO X1 DAE Power Cables: The Disk Array Enclosure (DAE) power cables are critical components in ensuring that the storage system remains operational. Removing these cables disconnects power to the DAE, which should only be done under specific circumstances.

Scenarios for Power Cable Removal:

Normal Shutdown Procedure: In a normal shutdown, the system is powered down gracefully using management interfaces and proper shutdown commands. Physical removal of power cables is typically not part of this process.

Shutdown after Initial Installation: After the initial installation, the system is powered on and configured. A shutdown would again follow a graceful procedure and not involve removing power cables unless there's a specific issue.

Shutdown due to Power Loss: In the event of power loss, the system would already be down, and there would be no need to remove the power cables as the system has lost power.

Emergency Shutdown Procedure: In an emergency, where the system must be immediately powered down to protect data or hardware, it may be necessary to remove the power cables quickly.

Best Practices and Safety:

Removing power cables as part of an emergency shutdown is typically a last resort measure when immediate power disconnection is required to prevent damage or ensure safety.

Following manufacturer guidelines for emergency shutdown ensures that the system is protected and can be safely restarted when the emergency is resolved.

XtremIO X1 User and Maintenance Guide

For a customer with an 80 TB database that will not benefit from compression and deduplication, and with no projected future growth, the minimum recommended XtremIO X1 offering would be the one that provides at least 80 TB of raw storage capacity.

Based on the options provided:

A. 20 TB 4 X-Brick model

B. 40 TB 4 X-Brick model

C. 10 TB 8 X-Brick model

D. 20 TB 6 X-Brick model

The most suitable option that meets the requirement of providing at least 80 TB of raw storage capacity would be B. 40 TB 4 X-Brick model. This is because each X-Brick in the XtremIO X1 system contributes to the total raw storage capacity, and with a 4 X-Brick model, each X-Brick would need to provide at least 20 TB to meet the 80 TB requirement. Since the 40 TB 4 X-Brick model offers 40 TB per X-Brick, it would exceed the required capacity, ensuring that the customer’s needs are met without any shortfall.

The image provided shows the back of an XtremIO X1 storage system with numeric labels next to the communication cable ports. To ensure the correct communication cables are connected:

Locate the ports on the back of the X-Bricks corresponding to the numeric labels.

Match each communication cable to its respective port based on the numeric label:

The right-side Battery Backup Unit (BBU) communication cable for X-Brick 5 (X5-BBU-COM-R) connects to port labeled 3.

The left-side BBU communication cable for X-Brick 5 (X5-BBU-COM-L) connects to port labeled 1.

The right-side BBU communication cable for X-Brick 6 (X6-BBU-COM-R) connects to port labeled 4.

The left-side BBU communication cable for X-Brick 6 (X6-BBU-COM-L) connects to port labeled 2.

After connecting the cables as per the matching, verify the connections according to the Official Dell XtremIO Deploy Achievement document to ensure they are correct and secure1.
