As promised, we’re constantly refreshing content on the VxRail Interactive Journey. For those not familiar with the awesomeness of the VxRail Interactive Journey, you can check out this short blog. In the latest release, there is a brand-new whiteboard video to walk you through the architectural framework of SaaS multi-cluster management in VxRail HCI System Software. As customers look to scale their VxRail footprint, the need for simple global management grows.
In this whiteboard video, you will learn how we’re able to extend the operational simplicity in VxRail to SaaS multi-cluster management and deliver that experience to you on an easy-to-use web portal. The video covers three key areas of SaaS multi-cluster management.
- Monitoring – The Adaptive Data Collector service in VxRail HCI System Software gathers telemetry data from the HCI stack for more streamlined monitoring of all your clusters.
- Multi-cluster management – The added use of the Secure Remote Services gateway for bi-directional communication between the VxRail clusters and the web portal enables LCM services at scale.
- Security – The need for managing who has access to clusters becomes even more important with cluster configuration capabilities.
I invite you to check out this new whiteboard video in the VxRail Interactive Journey. You can find it in the SaaS multi-cluster management module.

The signs of autumn are all around us, from the total takeover of pumpkin-spiced everything to the beautiful fall foliage worthy of Bob Ross’s inspiration. Like the amount of change autumn brings forth, so too does the latest release of VxRail ACE, or should I preface that with ‘formerly known as’? I’ll get to that explanation shortly.
This release introduces multi-cluster update functionality that will further streamline the lifecycle management (LCM) of your VxRail clusters at scale. With this active management feature comes a new licensing structure and role-based access control to enable the active management of your clusters.
Formerly known as VxRail ACE
The colors of the leaves are changing and so is the VxRail ACE name. The brand name VxRail ACE (Analytical Consulting Engine), will no longer be used as of this release. While it had a catchy name and was easy to say, there are two reasons for this change. First, Analytical Consulting Engine no longer describes the full value or how we intend to expand the features in the future. It has grown beyond the analytics and monitoring capabilities of what was originally introduced in VxRail ACE a year ago and now includes several valuable LCM operations that greatly expand its scope. Secondly, VxRail ACE has always been part of the VxRail HCI System Software offering. Describing the functionality as part of the overall value of VxRail HCI System Software, instead of having its own name, simplifies the message of VxRail’s value differentiation.
Going forward, the capability set (that is, analytics, monitoring, and LCM operations) will be referred to as SaaS multi-cluster management -- a more accurate description. The web portal is now referred to as MyVxRail.
Cluster updates is the first active management feature offered by SaaS multi-cluster management. It builds on the existing LCM operational tools for planning cluster updates: on-demand pre-update health checks (LCM pre-check) and update bundle downloads and staging. Now you can initiate updates of your VxRail clusters at scale from MyVxRail. The benefits of cluster updates on MyVxRail tie closely with existing LCM operations. During the planning phase, you can run LCM pre-checks of the clusters you want to update. This informs you if a cluster is ready for an update and pinpoints areas for remediation for clusters that are not ready. From there, you can schedule your maintenance window to perform a cluster update and, from MyVxRail, initiate the download and staging of the VxRail update bundle onto those clusters. With this release, you can now execute cluster updates for those clusters. Now that’s operational efficiency!
When setting a cluster update operation, you have the benefit of two pieces of information – a time estimate for the update and the change data. The update time estimate will help you determine the length of the maintenance window. The estimate is generated by telemetry gathered about the install base to provide more accurate information. The change data is the list of the components that require an update to reach the target VxRail version.

Role-based access control
Active management requires role-based access control so that you can provide permissions to the appropriate individuals to perform configuration changes to your VxRail clusters. You don’t want anyone with access to MyVxRail to perform cluster updates on the clusters. SaaS multi-cluster management leverages vCenter Access Control for role-based access. From MyVxRail, you will be able to register MyVxRail with the vCenter Servers that are managing your VxRail clusters. The registration process will give VxRail privileges to vCenter Server to build roles with specific SaaS multi-cluster management capabilities.
MyVxRail registers the following privileges on vCenter:
- Download software bundle: downloads and stages the VxRail software bundle onto the cluster
- Execute health check: performs an on-demand pre-update health check on the cluster
- Execute cluster update: initiates the cluster update operation on the clusters
- Manage update credentials: modifies the VxRail infrastructure credentials used for active management

VxRail Infrastructure Credentials
We’ve done more to make it easier to perform cluster updates at scale. Typically, when you’re performing a single cluster update, you have to enter the root account credentials for vCenter Server, Platform Services Controller, and VxRail Manager. That’s the same process when performing it from VxRail Manager. But that process can get tedious when you have multiple clusters to update.
VxRail Infrastructure Credentials can store those credentials so you can enter them once, at the initial setup of active management, and not have to do it again as you perform a multi-cluster update. MyVxRail can read the stored credentials that are saved on each individual cluster for security.
Big time saver! But how secure is it? More secure than hiding Halloween candy from children. For a user to perform cluster update, the administrator needs to add the ‘execute cluster update’ privilege to the role assigned to that user. Root credentials can only be managed by users assigned with a role that has the ‘manage update credentials’ privilege.

The last topic is licensing. While all the capabilities you have been using on MyVxRail come with the purchase of the VxRail HCI System Software license, multi-cluster update is different. This feature requires a fee-based add-on software license called ‘SaaS active multi-cluster management for VxRail HCI System Software’. All VxRail nodes come with VxRail HCI System Software and you have access to MyVxRail and SaaS multi-cluster management features, except for cluster update. For you to perform an update of a cluster on MyVxRail, all nodes in the clusters must have the add-on software license.
That is a lot to consume for one release. Hopefully, unlike your Thanksgiving meal, you can stay awake for the ending. While the brand name VxRail ACE is no more, we’re continuing to deliver value-adding capabilities. Multi-cluster update is a great feature to further your use of MyVxRail for LCM of your VxRail clusters. With role-based access and VxRail infrastructure credentials, rest assured you’re benefitting from multi-cluster update without sacrificing security.

Protecting VxRail From Unplanned Power Outages: More Choices Available

Read Time: 0 minutes
In my previous blog, Protecting VxRail from Power Disturbances, I described the first API-integrated solution that helps customers preserve data integrity on VxRail if there are unplanned power events. Today, I'm excited to introduce another solution that resulted from our close partnership with Schneider Electric (APC).
Why is it important?
Over the last few years, VxRail has become a critical HCI system and data-center building block for over 15,000 customers who have deployed more than 220,000 nodes globally. When HCI was first introduced, it was often considered for specific workloads such as VDI or ROBO locations. However, with the evolution of hardware and software capabilities, VxRail became a catalyst in data-center modernization, deployed across various use cases from core to cloud to edge. Today, customers are deploying VxRail for mission-critical workloads because it is powerful enough to meet the most demanding requirements for performance, capacity, availability, and rich data services.
Dell Technologies is a leader in data-protection solutions and offers a portfolio of products that can fulfill even the most demanding RPO and RTO requirements from customers. In addition to using traditional data-protection solutions, it is best practice to use a UPS to protect the infrastructure and ensure data integrity if there are unplanned power events. In this blog, I want to highlight a new solution from Schneider Electric, the provider of APC Smart-UPS systems.
The APC UPS protection solution for VxRail
Schneider Electric is one of Dell Technologies’ strategic partners in the Extended Technologies Complete Program. It provides Dell Technologies with APC UPS and IT rack enclosures offering a comprehensive solution set of infrastructure hardware, monitoring, management software, and service options.
PowerChute Network Shutdown in version 4.5 seamlessly integrates with VxRail by communicating over the network with the APC UPS. If there is a power outage, PowerChute can gracefully shut down VxRail clusters using the VxRail API. As a result of this integration, PowerChute can run on the same protected VxRail cluster, saving space and reducing hardware costs.
- VxRail cluster with VxRail HCI System Software version 7.0.320, 4.7.540 or higher
- Dell Smart-UPS Online 5kVA DLRT5KRMXLT or Dell Smart-UPS Online 3kVA DLRT3000RMXLA
- UPS Network Management Card 3 (AP9640, AP9640, or AP9643) with NMC firmware version v2.2 or higher
- Either a 1-Year or 3-Year PowerChute license for each VxRail node in the cluster (PowerChute Network Shutdown software version 4.5 or higher)
Key benefits of this solution include:
- Unattended, graceful shutdown of virtual machines (VMs), followed by the VxRail cluster that avoids data corruption thanks to integration with the VxRail API.
- Minimal downtime after critical events have passed with a pre-configured automated start-up sequence, which is useful at remote or unattended sites.
- Full deployment within the VxRail cluster saves space and reduces hardware requirements since you don't have to deploy PowerChute on a separate machine outside the cluster.
- Edge-ready with support for Edge-ready vSAN architecture with vSAN 2-node clusters.
- Redundant VxRail API-based cluster shutdown. In a redundant UPS set-up, if one NMC3 is offline, PowerChute will connect to one or more available NMC3s to carry out the VxRail cluster shutdown.
How does it work?
This is easiest to describe using the following diagram, which covers the steps taken in a power event and when the event is cleared:
How PowerChute Network Shutdown works with VxRail
I highly recommend watching the demo of this solution in action, which is listed in the Additional resources section at the end of this blog.
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 practice ensures data integrity by enabling automated and graceful shutdown of VxRail clusters. Customers now have more choice in providing such protection, with the new version of PowerChute Network Shutdown software for APC UPS systems integrated with VxRail API and validated with VxRail.
