These scenarios can apply to financial and medical industries among many others. This use case can be particularly relevant for customers who have standardized on VCF on VxRail as their infrastructural building block for their cloud operating model. Another significant change in the context of SD cards and USB devices is the ESX-OSData partition.As VxRail dynamic nodes were described in the external launch event, they benefit customers who are committed to continue running their mission-critical data-centric workloads on Dell EMC storage arrays because of the enterprise-level resiliency and data protection capabilities but value the operational certainty that VxRail offers to their IT teams. The rest of the partitions are dynamic, meaning partition size will be determined based on the boot media size. Service Level Interface (SLI)-1 firmware is no longer supported.With the new partition schema in vSphere 7.x, only the system boot partition is fixed at 100 MB.
Vsphere 7 Release Notes Update 28 SeptContents.Piqued your interest? Let’s move deeper into the technical details so you can better understand how VxRail dynamic nodes address these use cases. Check frequently for additions and updates to these release notes. For vSphere 7.0 Update 1 and VMC Last document update 28 Sept 2020. VDDK 7.0.1 ESXi build 16850804, VDDK build 16860560.![]() Vsphere 7 Release Notes Series Is TheThe E-series is the space-efficient 1U platform. While there are not any cache and capacity drives on dynamic nodes, all other hardware configurations on these models are available. The same intelligent LCM experience backed by VxRail’s Continuously Validated States exists in dynamic nodes.Like the three-flavor Neapolitan ice cream tub, there’s a flavor of dynamic nodes to match each application requirement.
![]() ![]() VxRail HCI System Software is responsible for the LCM of the dynamic nodes themselves. Management of the storage array and Fibre-Channel switch is done separately including lifecycle management, zoning, and provisioning of storage. Storage connectivity is through Fibre-Channel, either 16Gb or 32Gb Dell EMC Connectrix Brocade or Cisco MDS FC switches. Third-party storage arrays are not supported. With VxRail 7.0.240, Dell EMC PowerStore-T, PowerMax, and UnityXT are the supported external arrays for this use case. The V-series is optimized for GPU-acceleration with up to six GPUs per node.For those wanting to use their Dell EMC storage arrays with these brand-new VxRail dynamic nodes, here are some important pieces of information to consider. As shown on the image above, it provides a component-by-component report as part of the compliance check. Update advisor is a helpful tool to plan your maintenance window.Second, VxRail Manager now has a compliance checker that will detect any unforeseen version drift from the current Continuously Validated State running on your VxRail cluster. This feature does not replace your responsibility to review the release notes and decide on to which version to update their cluster but, it does generate an advisory report with critical information to let you know what needs to be updated based on your cluster’s current Continuously Validated State. From the Updates > Internet Updates tab, you can now see a list of available update paths for their specific cluster. There are three notable enhancements that VxRail users will notice – unless their thoughts have drifted away into those summertime memories.First, update advisor is a new tool to help you plan for their next cluster update. The storage array and dynamic nodes are sold separately and supported discretely by Dell Technologies.Now let’s move onto the LCM enhancements in VxRail 7.0.240. Vsphere 7 Release Notes Drivers And ToBased on the drift detection analysis between the baseline and desired state images, vLCM will remediate the hosts on the cluster to complete the update.VxRail’s newly introduced vLCM compatibility enables the VxRail Manager VM to plug into the framework to perform cluster updates using VxRail-provided desired state images in the form of Continuously Validated States. When updating the cluster, a desired state image is built from a combination of VMware-provided ESXi image and vendor(s)-provided firmware and drivers. Together, they form the baseline image which is used for the compliance checker. VMware supplies the base image which is the ESXi image, and then it is up to the hardware vendors, like Dell Technologies, to provide the hardware support manager that plugs into that framework to supply the necessary firmware and drivers and to update them. Design apps for computerConsolidate VMware software updates – for users that already run NSX-T or vSphere with Tanzu, vLCM allows for those VIBs to be included into the desired state image. In short, vLCM compatibility is mostly transparent to the user as the LCM experience still runs through VxRail Manager.The next likely question is why offer this enhancement? The explanation can be conveyed in two points both related to cutting down the time to update the cluster. From VxRail Manager, via the vLCM APIs, the bundle is loaded onto the vLCM framework as the desired state image. The simplicity of VxRail’s support for vLCM cannot be understated.Figure 6: VxRail’s vLCM implementation automates and simplifies the user’s cluster update experienceSimilarly, performing cluster updates is a streamlined process once the LCM bundle is downloaded onto the VxRail Manager VM. Because VxRail Manager already stores the Continuously Validated State on its VM, the process of identification and exporting of the hardware firmware and drivers on the VxRail stack can easily be automated. While other hardware support manager plugins to vLCM require a multiple-step procedure to establish a baseline image and desired state image and interaction with multiple interfaces, VxRail’s implementation leverages the vLCM APIs to truly obfuscate those complexities into a streamlined experience all within VxRail Manager. The vendor addon feature in vLCM, as shown in the image above, provides the capability to include component firmware/drivers into the cluster image for a consolidated update cycle. Those components would then need to be updated separately which may require additional host reboots. Consolidate non-VxRail managed components – there are a few components such as the FC HBA that are not part of Continuously Validated State. Free accurate mt4 indicatorsDeveloping vLCM compatibility is also a strategic decision to put VxRail in a position to enhance more vLCM capabilities as they come. Users can choose to enable vLCM immediately or enable it later. With VxRail 7.0.240, the use of vLCM is disabled by default.

Though the summer is drawing to a close, VxRail is providing you the boost to stay dynamic and finish 2021 strong.
