When creating a cluster, in addition to the cluster name, the following parameters are required: the expected number of X-Bricks, the IP address of X1-SC1 (the first Storage Controller), and the package name. These parameters are essential for setting up the cluster configuration and ensuring proper communication between components.

When the NVRAM status LED on an XtremIO X2 is flashing red at one-second intervals, it indicates an uncorrectable error. This is a critical status that typically signifies a hardware malfunction or failure within the NVRAM module, which requires immediate attention. NVRAM, or Non-Volatile Random Access Memory, is crucial for retaining data integrity during power losses or system crashes1.

The steps to address this issue usually involve:

Investigating the system logs to identify the specific nature of the error.

Contacting Dell EMC support for guidance on diagnosing and resolving the issue.

Following the recommended procedures for troubleshooting or replacing the affected NVRAM module, as per the support team's instructions.

It is important to resolve such errors promptly to prevent potential data loss and to maintain the overall health and performance of the storage system1.

=========================

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.

The field replaceable units (FRUs) on an XtremIO X1 Storage Controller include the entire component and the Power Supply Unit (PSU). This information is verified as per the Official Dell XtremIO Maintenance Achievement document, which outlines the FRU replacement procedures for XtremIO products1.

The virtual XtremIO Management Server (XMS) OVA file can be found in the Tools & Utilities download section on support.emc.com. This is confirmed by the information provided in the Dell XtremIO Maintenance Achievement document, which details the resources and procedures for maintaining XtremIO products, including the deployment of the XMS1.

XtremIO X2 clusters are designed for efficient space utilization in data center racks.

A four X-Brick XtremIO X2 cluster requires specific rack space allocation.

Each X-Brick occupies 5U of rack space. Therefore, four X-Bricks would require 20U.

Additionally, the physical XtremIO Management Server (XMS) occupies 1U of rack space.

In total, the four X-Brick XtremIO X2 cluster with a physical XMS requires 21U of rack space.

In the event of a power failure, the XtremIO X2 array is designed to protect the journal data using a combination of Supercapacitor and NVRAM. The NVRAM (Non-Volatile Random Access Memory) ensures that the data remains intact without power, while the supercapacitor provides the necessary energy to maintain the power to the NVRAM during the outage. This design allows the XtremIO X2 array to preserve the integrity of the journal data until normal power can be restored1.

=========================

In an XtremIO X1 cluster, the system is designed to tolerate the failure of one DAE Controller SAS port without any impact on the service or data integrity. This is because the architecture of the XtremIO X1 includes redundancy and failover mechanisms that ensure continuous operation even when individual components fail. The failure of a single SAS port would trigger these mechanisms, allowing the system to maintain normal operations and prevent data loss, service degradation, or loss of service1.
