To interact with an XtremIO cluster using the REST API, the application that can be used is cURL. cURL is a command-line tool and library for transferring data with URLs and is commonly used for various types of HTTP requests.

The steps to use cURL with the XtremIO REST API are as follows:

Install cURL: Ensure that cURL is installed on your system. It is available for a variety of platforms including Windows, Mac, and Linux.

Prepare the API Request: Formulate your REST API request. This will include the XtremIO cluster’s endpoint and the specific API call you wish to make.

Execute the cURL Command: Use the cURL command in your terminal or command prompt to execute the API request. The general syntax for a cURL request is:

curl [options] [URL]

For example, to list all volumes on an XtremIO cluster, you might use:

curl -u username:password -X GET " "

Replace username:password with your actual credentials and XMS_IP_Address with the IP address of your XtremIO Management Server (XMS).

Analyze the Response: The response from the XtremIO cluster will be output to your terminal. It will typically be in JSON format, which you can then parse and analyze as needed.

Reference Documentation: For detailed information on the REST API calls available and their usage, refer to the official Dell XtremIO Deploy Achievement document1. This document will provide comprehensive guidance on implementing solutions using XtremIO systems, including the use of REST API for cluster interaction.

By following these steps and referring to the official documentation, you can successfully use cURL to interact with an XtremIO cluster via the REST API.

Understanding Execution Throttle: The Execution Throttle setting controls the maximum number of concurrent I/O operations that can be sent from a host to a storage array. This setting is crucial for optimizing performance and preventing overloading of the storage array.

QLogic Fibre Channel HBAs: QLogic Host Bus Adapters (HBAs) are used for connecting servers to Fibre Channel storage networks. The recommended settings for these HBAs can significantly impact the performance and reliability of the storage network.

Best Practices for XtremIO and VMware:

According to best practices for connecting VMware clusters to XtremIO arrays, especially when using QLogic Fibre Channel HBAs, the Execution Throttle value is set to optimize performance.

The recommended value for the Execution Throttle setting for QLogic HBAs in a VMware environment connected to an XtremIO array is 65535. This value helps ensure that the host can handle a high number of I/O operations efficiently without overwhelming the storage array.

The RESTful API method used to retrieve an existing configuration from an XtremIO system is the HTTP GET methD. This is a standard method used in RESTful APIs for retrieving resources. In the context of XtremIO, the GET method would be used to call endpoints that return information about the system’s configuration. For example, a GET request to /api/json/v2/types/clusters would retrieve information about the clusters1. The Official Dell XtremIO Deploy Achievement document will contain specific details on the API calls and should be referred to for the most accurate instructions.
