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.

Power Connectors for XtremIO X2 Dual X-Brick Configuration: Each X-Brick typically requires multiple power connections for redundancy and reliability. A dual X-Brick configuration without a physical XMS would need to account for these requirements.

Calculation:

Each X-Brick has 2 storage controllers, each requiring 2 power connections, totaling 4 power connections per X-Brick.

For a dual X-Brick configuration: 4 power connections per X-Brick * 2 X-Bricks = 8 power connections.

Each DAE (Disk Array Enclosure) typically requires 2 power connections. In a dual X-Brick setup, there are 4 DAEs, totaling 8 power connections.

Total power connections: 8 (for X-Bricks) + 8 (for DAEs) = 16 power connections.
