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.

In an XtremIO X1 system, a full data protection group (DPG) can tolerate the loss of up to 5 drives before a data loss occurs. The XtremIO architecture ensures high availability andredundancy, but losing more than 5 drives within a DPG exceeds the system's ability to protect data, leading to potential data loss.

For an XtremIO cluster to use FTPS (File Transfer Protocol Secure) for the Connect Home feature, the firewall ports that need to be opened are989 and 990.These ports are used for data connections and control connections under implicit security for FTPS1.

When using explicit security, FTPS can also use port 21, but since the question specifies FTPS for Connect Home, which typically uses implicit security, the correct ports are989 for data transmissionand990 for the control connection1. It’s important to ensure these ports are open to allow secure file transfer capabilities for the XtremIO cluster.

When connected to the Tech port on a Dell XtremIO Storage Controller, the login name "xinstall" should be used to test the Storage Controller cabling. This special login is designated for installation and configuration tasks, including testing and verifying cabling connections to ensure proper setup and functionality of the storage system.

The XtremIO X2 storage system can be expanded for capacity (Scale-Up) or both capacity and performance (Scale-Out). The system begins with a single building block, called an X-Brick, with a minimum of 18 SSDs.When additional capacity is required, the system scales up, with up to 72 SSDs for a single X-Brick1. Therefore, to upgrade a single X-Brick XtremIO X2 cluster that already contains 36 SSDs, the minimum number of SSDs required would be 18, which is the base configuration for an X-Brick.

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

The correct racking order from bottom to top to expand an XtremIO X1 configuration from a dual X-Brick to a quad X-Brick is as follows:

X3-SC1

X3-DAE

X3-BBU

X3-SC2

As per the image provided, which appears to be a list or part of a document detailing the steps for racking components, the order listed for expanding an XtremIO X1 configuration is:

Begin with the bottom component, which is ‘X3-SC1’ (Storage Controller 1).

Above ‘X3-SC1’, install ‘X3-DAE’ (Disk Array Enclosure).

Next, install ‘X3-BBU’ (Battery Backup Unit) above ‘X3-DAE’.

Finally, at the top, place ‘X3-SC2’ (Storage Controller 2).

This order ensures that the heavier components are at the bottom for stability and likely follows Dell’s official guidelines for proper airflow and cable management within the rack1.

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

To replace a power supply unit (PSU) in a storage controller of an XtremIO cluster, a specific command needs to be executed.

The correct command to initiate this process is replace-storage-controller-psu sc-psu-id=1 cluster-id="ABC123".

This command specifies the action to replace the PSU (replace-storage-controller-psu), the PSU ID (sc-psu-id=1), and the specific cluster ID (cluster-id="ABC123").

Using this command ensures that the correct PSU in the specified cluster is prepared for replacement.

To successfully operate Technician Advisor on an XtremIO X2, TCP ports 80 and 443 need to be open between the XMS (XtremIO Management Server) and X1-SC1 (Storage Controller). These ports are used for HTTP and HTTPS communication, respectively, allowing for secure management and operation of the storage system.

In a single X-Brick XtremIO X2 configuration, the port SC1-IB1 should be connected to IBSW1-P01. This connection ensures proper communication and data flow between the storage controller and the InfiniBand switch, which is critical for system 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.
