EMC D-XTR-DY-A-24 - Dell XtremIO Deploy Achievement

The largest size supported for each volume in a new XtremIO X2-S single X-Brick cluster, as per the Official Dell XtremIO Deploy Achievement documents, is 64 TB. This information is verified through the official documentation which outlines the capabilities and specifications of the XtremIO X2 systems. The documents provide a detailed description of the critical components, features, and implementation solutions in customer environments, which includes the storage capacity specifications for XtremIO systems1.

In XtremIO, configuring email notifications involves several steps, including setting up the email server and defining alert definitions. While the email server may be correctly configured and tested, notifications will not be sent unless the alert definitions are also set up. Alert definitions specify the conditions under which notifications are sent, including the severity level of issues. If major severity alerts are not defined, the email server will not trigger notifications for those events.

Understanding XtremIO XMS Requirements: The XtremIO Management Server (XMS) is a dedicated server that manages one or more XtremIO clusters. Each XMS can manage multiple clusters, but there are limitations depending on the software version.

Software Version Compatibility:

XtremIO Software 4.0.4-41: This version can manage multiple clusters with a single XMS server.

XtremIO Software 3.0.3-11: This version has more stringent requirements and typically requires a separate XMS server for each cluster due to its older architecture and limitations.

Cluster Configuration:

For the two clusters running 4.0.4-41, a single XMS server can manage both.

For the two clusters running 3.0.3-11, each cluster will require its own XMS server.

Calculation of Minimum XMS Servers:

1 XMS server for the two clusters with software version 4.0.4-41.

2 XMS servers for the two clusters with software version 3.0.3-11.

Therefore, the total minimum number of XMS servers required = 1 (for 4.0.4-41) + 2 (for 3.0.3-11) = 3.

Understanding X-Bricks: X-Bricks are the fundamental building blocks of an XtremIO storage array. Each X-Brick consists of a pair of storage controllers and a set of SSDs.

XtremIO X1 Cluster Configuration:

An XtremIO X1 cluster can scale by adding more X-Bricks.

The scalability and configuration limits depend on the hardware and software capabilities of the XtremIO X1 system.

Maximum Number of X-Bricks:

The XtremIO X1 cluster can be configured with up to 4 X-Bricks.

This means the maximum configuration for an XtremIO X1 cluster would include 4 X-Bricks.

Cable Management: Proper cable management is crucial for maintaining an organized and efficient data center environment.

Rack Units: For an XtremIO X2-R four X-Brick cluster, it is recommended to allocate 6U for the cable management ducts.

Space Allocation: This ensures that there is enough space to manage and organize cables without causing congestion or interfering with airflow.

show-clusters-info Command: This command is used to display the status and information of an XtremIO cluster.

Healthy State: For a healthy XtremIO cluster, the state displayed is "Active and enabled".

Verification: This state indicates that the cluster is operational and all services are functioning as expected.

When configuring Linux hosts to support XtremIO storage, it is recommended to set the LUN queue depth to 64. This setting helps to optimize the performance of the host when communicating with the XtremIO storage system.

Access Host Configuration: Log into the Linux host that will be connected to the XtremIO storage.

Modify HBA Parameters: Locate the HBA (Host Bus Adapter) parameters within the host’s configuration files.

Set Queue Depth: Adjust the queue depth parameter for the HBA to 64. This can typically be done by editing the options.conf file or similar, depending on the HBA driver in use.

Apply Changes: Save the changes and reload the HBA driver or reboot the host to apply the new configuration.

Verify Configuration: Confirm that the new queue depth setting is active and functioning as expected.

When initializing an XtremIO cluster for the first time using the create-cluster command, it is essential to provide the cluster's unique identifier, known as the cluster-psnt (Product Serial Number Tag). This parameter ensures that the system can accurately identify and manage the cluster throughout its operational lifecycle. Other parameters, such as hw-package, profile, and package, may be relevant in different contexts, but the cluster-psnt is a mandatory parameter for initial cluster creation.

Power the PDUs: The Power Distribution Units (PDUs) need to be powered first as they supply power to all the other components.

Power on the BBUs: The Battery Backup Units (BBUs) are powered on next to ensure that the system has emergency power in case of a power failure.

Power on the Storage Controllers: The storage controllers are responsible for managing the storage array, so they need to be powered on before the server.

Power on the physical XMS Server: Finally, the XMS server, which provides management and monitoring capabilities, is powered on.
