VxRail REST APIs
The Challenge
VxRail Manager, available as a part of HCI System Software, drastically simplifies the lifecycle management and operations of a single VxRail cluster. With a “single click” user experience available directly in vCenter interface, you can perform a full upgrade off all software components of the cluster, including not only vSphere and vSAN, but also complete server hardware firmware and drivers, such as NICs, disk controller(s), drives, etc. That’s a simplified experience that you won’t find in any other VMware-based HCI solution.
But what if you need to manage not a single cluster, but a farm consisting of dozens or hundreds of VxRail clusters? Or maybe you’re using some orchestration tool to holistically automate the IT infrastructure and processes? Would you still need to login manually as an operator to each of these clusters separately and click a button to maybe shutdown a cluster, collect log information or health data or perform LCM operations?
This is where VxRail REST APIs come in handy.
The VxRail API Solution
REST APIs are very important for customers who would like to programmatically automate operations of their VxRail-based IT environment and integrate with external configuration management or cloud management tools.
In VxRail HCI System Software 4.7.300 we’ve introduced very significant improvements in this space:
- Swagger integration - which allows for simplified consumption of the APIs and their documentation;
- Comprehensiveness – we’ve almost doubled the number of public APIs available;
- PowerShell integration – that allows consumption of the APIs from the Microsoft PowerShell or VMware PowerCLI.
The easiest way to start using and access these APIs is through the web browser, thanks to the Swagger integration. Swagger is an Open Source toolkit that simplifies Open API development and can be launched from within the VxRail Manager virtual appliance. To access the documentation, simply open the following URL in the web browser: https://<VxM_IP>/rest/vxm/api-doc.html (where <VxM IP> stands for the IP address of the VxRail Manager) and you should see a page similar to the one shown below:

This interface is dedicated for customers, who are leveraging orchestration or configuration management tools – they can use it to accelerate integration of VxRail clusters into their automation workflows. VxRail API is complementary to the APIs offered by VMware.
Would you like to see this in action? Watch the first part of the recorded demo available in the additional resources section.
PowerShell integration for Windows environments
Customers, who prefer scripting in Windows environment, using Microsoft PowerShell or VMware PowerCLI, will benefit from VxRail.API PowerShell Modules Package. It simplifies the consumption of the VxRail REST APIs from PowerShell and focuses more on the physical infrastructure layer, while management of VMware vSphere and solutions layered on the top (such as Software-Defined Data Center, Horizon, etc.), can be scripted using similar interface available in VMware PowerCLI.

To see that in action, check the second part of the recorded demo available in the additional resources section.
Bringing it all together
VxRail REST APIs further simplify IT Operations, fostering operational freedom and a reduction in OPEX for large enterprises, service providers and midsize enterprises. Integrations with Swagger and PowerShell make them much more convenient to use. This is an area of VxRail HCI System Software that rapidly gains new capabilities, so please make sure to check the latest advancements with every new VxRail release.

VxRail API—Updated List of Useful Public Resources
Fri, 20 Nov 2020 18:16:21 -0000
|Read Time: 0 minutes
Well-managed companies are always looking for new ways to increase efficiency and reduce costs while maintaining excellence in the quality of their products and services. Hence, IT departments and service providers look at the cloud and Application Programming Interfaces (APIs) as the enablers for automation, driving efficiency, consistency, and cost-savings.
This blog helps you get started with VxRail API by grouping the most useful VxRail API resources available from various public sources in one place. This list of resources is updated every few months. Consider bookmarking this blog as it is a useful reference.
Before jumping into the list, it is essential to answer some of the most obvious questions:
What is VxRail API?
VxRail API is a feature of the VxRail HCI System Software that exposes management functions with a RESTful application programming interface. It is designed for ease of use by VxRail customers and ecosystem partners who want to better integrate third-party products with VxRail systems. VxRail API is:
- Simple to use—Thanks to Swagger and PowerShell integration, you can consume the API easily using a supported web browser or from a familiar command-line interface for Windows and VMware vSphere administrators.
- Powerful—VxRail offers dozens of API calls for essential operations such as automated life cycle management (LCM), and its capabilities are growing with every new release.
- Extensible—This API is designed to complement REST APIs from VMware (such as vSphere Automation API, PowerCLI, and VMware Cloud Foundation on Dell EMC VxRail API), offering a familiar look and feel and vast capabilities.
Why is VxRail API relevant?
VxRail API enables you to use the full power of automation and orchestration services across your data center. This extensibility enables you to build and operate infrastructure with cloud-like scale and agility. It also streamlines the integration of the infrastructure into your IT environment and processes. Instead of manually managing your environment through the user interface, the software can programmatically trigger and run repeatable operations.
More customers are embracing DevOps and Infrastructure as Code (IaC) models because they need reliable and repeatable processes to configure the underlying infrastructure resources that are required for applications. IaC uses APIs to store configurations in code, making operations repeatable and greatly reducing errors.

Protecting VxRail from Power Disturbances
Fri, 12 Jun 2020 13:03:51 -0000

Preserving data integrity in case of unplanned power events
The challenge
Over the last few years, VxRail has evolved significantly -- becoming an ideal platform for most use cases and applications, spanning the core data center, edge locations, and the cloud. With its simplicity, scalability, and flexibility, it’s a great foundation for customers’ digital transformation initiatives, as well as high value and more demanding workloads, such as SAP HANA.
Running more business-critical workloads requires following best practices regarding data protection and availability. Dell Technologies specializes in data protection solutions and offers a portfolio of products that can fulfill even the most demanding RPO/RTO requirements from our customers. However, we are probably not giving enough attention to the other area related to this topic: protection against power disturbances and outages. Uninterruptible Power Supply (UPS) systems are at the heart of a data center’s electrical systems, and because VxRail is running critical workloads, it is a best practice to leverage a UPS to protect them and to ensure data integrity in case of unplanned power events. I want to highlight a solution from one of our partners – Eaton.
The solution
Eaton is an Advantage member of the Dell EMC Technology Connect Partner Program and the first UPS vendor who integrated their solution with VxRail. Eaton’s solution is a great example of how Dell Technologies partners can leverage VxRail APIs to provide additional value for our joint customers. Having integrated Eaton’s Intelligent Power Manager (IPM) software with VxRail APIs, and leveraged Eaton’s Gigabit Network Card, the solution can run on the same protected VxRail cluster. This removes the need for additional external compute infrastructure to host the power management software - just a compatible Eaton UPS is required.
The solution consists of:
- VxRail version min. 4.5.300, 4.7.x, 7.0.x and above
- Eaton IPM SW v 1.67.243 or above
- Eaton UPS – 5P, 5PX, 9PX, 9SX, 93PM, 93E, 9PXM
- Eaton M2 Network Card FW v 1.7.5
- IPM Gold License Perpetual
The main benefits are:
- Preserving data integrity and business continuity by enabling automated and graceful shutdown of VxRail clusters that are experiencing unplanned extended power events
- Reducing the need for onsite IT staff with simple set-up and remote management of power infrastructure using familiar VMware tools
- Safeguarding the VxRail system from power anomalies and environmental threats
How does it work?
It’s quite simple (see the figure below). What’s interesting and unique is that the IPM software, which is running on the cluster, delegates the final shutdown of the system VMs and cluster to the card in the UPS device, and the card uses VxRail APIs to execute the cluster shutdown.
Figure 1. Eaton UPS and VxRail integration explained
Summary
Protection against unplanned power events should be a part of a business continuity strategy for all customers who run their critical workloads on VxRail. This ensures data integrity by enabling automated and graceful shutdown of VxRail cluster(s). Eaton’s solution is a great example of providing such protection and how Dell Technologies partners can leverage VxRail APIs to provide additional value for our joint customers.
