EMC D-XTR-OE-A-24 - Dell XtremIO Operate Achievement

According to Dell XtremIO documentation, when upgrading an XtremIO X2 two X-Brick cluster, the minimal number of SSDs that can be ordered is 12.

XtremIO clusters use a scale-out architecture, and each X-Brick requires a specific number of SSDs for proper functioning.

The upgrade process is designed to maintain the performance and resilience of the storage system.

The specific requirement of 12 SSDs ensures balanced data distribution and optimal performance across the cluster.

To double the throughput on an existing dual XtremIO X1 10 TB X-Brick cluster, adding a dual 10 TB X-Brick Expansion Kit is recommended.

XtremIO uses a scale-out architecture, and adding a dual X-Brick expansion will increase both storage capacity and performance.

This expansion ensures balanced performance improvement and leverages the best practices configuration already in place for the existing setup.

To create an iSCSI portal using the XtremIO X2 XMS WebUI, an administrator should navigate to Cluster Settings.

Within Cluster Settings, the configuration options for creating and managing iSCSI portals are available.

This is the starting point for setting up network configurations and ensuring the proper operation of iSCSI connections.

In EMC’s AppSync, the Service Plan Administrator role is responsible for managing service plans and RPOs (Recovery Point Objectives).This role includes the ability to register applications for protection and configure their RPOs, which aligns with the responsibilities described for the new administrator1.

The Service Plan Administrator has the privileges needed to assign service levels and manage protection policies within AppSync.This role is crucial for ensuring that applications are protected according to the organization’s specific recovery requirements and service level agreements1.

The other roles mentioned, such as Data Administrator, Security Administrator, and Resource Administrator, have different sets of responsibilities and privileges that do not specifically align with the task of registering applications for protection and configuring RPOs within AppSync1. Therefore, the correct privilege level for a new administrator with these responsibilities would be the Service Plan Administrator.

Each X-Brick in an XtremIO environment requires at least one RecoverPoint Appliance (RPA) to manage replication tasks effectively.

RecoverPoint provides both synchronous and asynchronous replication, ensuring data integrity and disaster recovery capabilities.

The RPA is crucial for handling replication operations and maintaining data consistency across XtremIO clusters.

The Compression ratio in the XtremIO X1 web interface dashboard is calculated by dividing theLogical Space in Useby thePhysical Space Used. This ratio provides an indication of the data reduction achieved through compression by comparing the amount of logical data (the size of data before compression) to the actual physical space it occupies after compression.

Logical Space in Use: This represents the total size of the data as it would appear without any compression. It’s the amount of space the data would consume if it were stored uncompressed.

Physical Space Used: This is the actual amount of storage space used on the SSDs after the data has been compressed. It reflects the efficiency of the compression algorithm in reducing the size of the data.

Compression Ratio Calculation: The compression ratio is obtained by dividing the Logical Space in Use by the Physical Space Used. A higher ratio indicates more effective compression, meaning that the data occupies significantly less physical space compared to its original size.

The compression ratio is a critical metric in storage systems as it directly impacts the total effective capacity of the array.In the context of XtremIO, which is known for its data reduction technologies, monitoring the compression ratio helps in understanding the efficiency of storage utilization and planning for capacity1.

Please note that while I can provide general information on how compression ratios are typically calculated in storage systems, for the verified answer as per the Official Dell XtremIO Operate Achievement documents, you would need to consult the document directly or seek information from a Dell-certified professional who has access to the latest materials and training.

The RESTful API method used to retrieve an existing configuration from a system like XtremIO is the HTTP GET methD.The GET method is used to request data from a specified resource and is one of the most common HTTP methods used in RESTful APIs1.

In the context of the XtremIO REST API, the GET method would be used to access various types of information about the array’s configuration.For example, to retrieve details about the volumes configured on an XtremIO array, you would issue a GET request to the appropriate endpoint of the XtremIO REST API2.

The HTTP POST method, on the other hand, is typically used to send data to the server to create or update a resource.The terms HTTP RETRIEVE and HTTP GATHER are not standard RESTful API methods and are not used in the context of the XtremIO REST API or any RESTful API1.

Minimum 4 Datastores:Based on best practices for VMware Horizon environments, with 1000 linked clones, it is recommended to have a minimum of 4 datastores connected to XtremIO.

This configuration helps distribute the load and ensures optimal performance and manageability.

The transfer rate for disk 19F shown in the exhibit is 2 MB/s. The exhibit indicates that the scale for "Disk Bytes/sec" is set to 0.00010000. Given this scale, the displayed value of approximately 200 (in the highlighted blue line) corresponds to 200 x 0.00010000 MB/s, which equals 2 MB/s.
