For an XtremIO X2 dual X-Brick cluster configuration without a physical XMS installed, the total number of power connectors required in a customer rack is 8. This is based on the system specifications which state that a 2 Brick Cluster requires 16 x IEC C14 power sockets1. Since the physical XMS would typically require additional power sockets, and it is not included in this configuration, the total number of power connectors needed would be less than the specified 16.

Here's the breakdown:

Each X-Brick in a dual X-Brick configuration would require power for its controllers and DAEs.

The InfiniBand switches included in a multi X-Brick system would also require power.

Without the physical XMS, which would normally need its own power connectors, the total comes down to 8 connectors required for the dual X-Brick setup1.

Answer : A

For the integration of Oracle with XtremIO, the best practice for HBA drivers includes setting the LUN-queue depth to optimize performance. If a single host is connected to the X-Brick, the LUN-queue depth can be set to the maximum supported by the HBA, which is 256 for QLogic HBAs1. As additional hosts are added, this setting should be reduced proportionately until reaching a minimum of 32 to maintain optimal performance1.

Assess Host Connection: Determine the number of hosts connected to the X-Brick.

Set Queue Depth: For a single host, set the queue depth to 256. Adjust as necessary when more hosts are added.

Configure HBA Settings: Apply the queue depth setting in the HBA configuration.

Test Performance: Monitor the system's performance to ensure the settings are optimal.

Adjust if Necessary: If performance issues are observed, adjust the queue depth settings as needed.
