VxRail HCI System Software
15
Dell VxRail System Tech Book
A Hyperconverged Infrastructure System from Dell Technologies and VMware
VxRail LCM is built on ecosystem connectors to integrate vSAN cluster software and
PowerEdge server hardware so that the ESXi host can be managed as a single system.
This system integration enables automation and orchestration necessary to deliver
nondisruptive, streamlined HCI stack updates. VxRail LCM delivers differentiated value
through the ability to deliver prevalidated sets of software and firmware. Prevalidation
ensures compatibility and compliance of the HCI stack configuration while maintaining the
performance and availability required of the virtualized workloads running on the clusters.
Tested and validated VxRail software bundles that support every vSphere release, any-to-
any version update paths, and the millions of VxRail configurations are “Continuously
Validated States.” These Continuously Validated States are recorded on the Electronic
Compatibility Matrix. The VxRail team’s $125 million investment in equipment and more
than 100 team members dedicated to testing and quality make this possible.

Customer updateable software
The VxRail software bundle is customer updateable through a fully automated and
validated process. The automated software update is initiated from the VxRail Manager
plug-in. VxRail Manager automatically downloads all software that is ready to be updated
including VxRail HCI System Software, VxRail-managed vCenter Server, vSphere, and
server component firmware and drivers. Customer-managed vCenter Server, Secure
Connect Gateway, and RecoverPoint for VMs are not part of VxRail LCM and must be
updated separately. The automated process consists of the following steps:
1. Acquire VxRail software bundle. In the VxRail Manager UI, the update advisor tool
lists the available update paths for the cluster. Users can select an update path to
review a list of the component changes needed to complete the update. Once a
decision has been made on the target version, users can initiate an Internet
download from the update advisor. For sites lacking Internet connectivity, update
bundles can also be locally uploaded to the cluster. In this scenario, users need to
separately acquire the bundle and upload it from a machine in the same local
network as the VxRail cluster.

The VxRail software bundle is customer updateable through a fully automated and validated process. The automated software update is initiated from the VxRail Manager plug-in. VxRail Manager automatically downloads all software that is ready to be updated including VxRail HCI System Software, VxRail-managed vCenter Server, vSphere, and server component firmware and drivers.

  1. Run the cluster readiness precheck, which can be initiated from the VxRail Manager UI. The pre-check determines the readiness of the cluster to successfully complete a cluster update. If the pre-check finds any issues, customers can address them in advance. The combination of this pre-check update, advisory report, and an estimated update time provides important information to help customers schedule an accurate maintenance window.
  2. Initiate the cluster update operation, or schedule the update, from the VxRail Manager UI. To start a cluster update, provide proper credentials for vCenter, the ESXi host, and VxRail Manager. Note : Alternatively, customers can make a REST API call to update the software that has been downloaded onto the VxRail system. Optionally, with the latest VxRail software releases, customers can customize the update image with additional firmware and drivers for components that are not part of the Continuously Validated State, such as Fibre Channel HBAs. Previously, updating components not managed by VxRail required a separate update.
  3. Monitor the progress of the update operation from the VxRail Manager UI. When the cluster update is completed, the final validation step ensures that the update was successful, and the VxRail system is fully functional with the updated software. A copy of the updated bundle is also stored as a recovery bundle in the VxRail Manager VM. The following figure shows the automated steps of a customer-run VxRail software bundle update. Figure 5. VxRail update workflow Step 3 is performed one node at a time, where the ESXi host is placed in maintenance mode, and, using vMotion, the VMs are moved to other nodes, making the update process nondisruptive. During a cluster update, VxRail Manager enables DRS to move VMs from the ESXi host that is being updated, providing for nondisruptive updates. DRS is enabled to move the VMs even if the cluster is not licensed to use DRS, due to Dell Technologies’ partnership with VMware. In the latest VxRail software versions, the cluster update operation has been enhanced by prestaging the next node with the update bundle as the current node is processed.

18 Dell VxRail System Tech Book end update should be nondisruptive to improve uptime. VxRail delivers this value with its tight integration of VMware software and PowerEdge server hardware. VxRail delivers configuration stability with Continuously Validated States. Customers get a prevalidated configuration that enables them to take advantage of the latest features and updates, rather than having to take on the work and risk themselves. Business operations are not affected. Customers get the latest capabilities, while the platform continues to meet security standards and compliance. At the top of the customer value chain for life cycle management is decision support. This area is where HCI vendors will look to deliver in the next few years because it will help drive down operational costs even further. By using artificial intelligence (AI) to improve and enhance decision-making, IT staff can further offload the burden of infrastructure management. Decision support is an area in which VxRail is starting to deliver some capabilities, most notably with SaaS multi-cluster management. VxRail management has expanded beyond the VxRail Manager plug-in for vCenter to allow for different use cases. VxRail Manager is a plug-in for vCenter that provides a fully integrated experience to manage VxRail clusters on a familiar interface. REST APIs extend the VxRail LCM capabilities for cloud deployment solutions. They also extend LCM capabilities for organizations that want to deploy and manage VxRail clusters at scale, when running batch scripts, configuration management tools (such as Ansible, Puppet, and so on), or custom automation for cluster operations is more efficient. SaaS multi- cluster management is a cloud-based management option for global orchestration of all the customer’s clusters from a single web portal interface. While VxRail Manager provides the complete management capability set for VxRail clusters, using REST APIs and SaaS multi-cluster management has its benefits. Over time, the gaps in functionality will close to further enhance the value that each brings for their respective use cases.

VxRail Manager

VxRail Manager features user-friendly workflows for automating VxRail deployment and configuration and for monitoring the health of individual systems in the entire cluster. VxRail Manager also incorporates functionality for hardware serviceability and system platform life cycle management. For instance, it guides system administrators through the process of adding systems to an existing cluster, and it automatically detects new systems when they come online. VxRail Manager is also used to replace failed disk drives without disrupting availability to generate and download diagnostic log bundles and apply VMware updates or software patches non-disruptively across VxRail nodes. With the VxRail Manager plug-in for vCenter Server, all VxRail Manager features are integrated with and accessible from the vCenter Server so that users can benefit from them on a familiar management interface. With the VxRail Manager plug-in, the vCenter Server can manage physical hardware of the VxRail cluster.
