What’s New In VMware Cloud Foundation 9.0

by Tommy Grot June 17, 2025

written by Tommy Grot 5 minutes read

In today’s rapidly evolving digital landscape, businesses need the agility and scalability of the cloud, without sacrificing the control and security of on-premises infrastructure. VMware Cloud Foundation (VCF) has long been a leader in bridging that gap, and the latest release, VCF 9.0, represents a significant leap forward.

VCF 9.0 isn’t just a platform; it’s the most trusted private cloud foundation for running all your applications – from mission-critical databases and enterprise applications to modern, cloud-native workloads. It delivers a consistent, simplified cloud experience, empowering cloud administrators to automate and streamline operations, developers to rapidly innovate, and ultimately, your business to thrive. In this post, we’ll dive into what makes VCF 9.0 a game-changer, exploring the key new features and how they benefit everyone from the data center to the developer desktop.

One Interface for Consumption & Administration: The core of this unification is a dramatically simplified and consistent management experience. VCF 9.0 leverages the VCF Operations/Automation family (formerly Aria) deeply integrated into the platform. This means developers and administrators alike access a single interface – VCF Operations/Automation – to provision and manage both traditional VMs and container-based applications running on vSphere Kubernetes Services (VKS).

This eliminates the need to switch between different consoles, learn multiple workflows, and reconcile inconsistencies across environments. Self-service capabilities within VCF Operations/Automation empower developers to rapidly deploy applications, while administrators maintain centralized control and governance. The introduction of Aria Universal simplifies lifecycle management across multi-cloud deployments.

Run VMs and Containers/K8s: VCF 9.0 natively integrates vSphere Kubernetes Services (VKS), allowing organizations to run modern, cloud-native applications alongside existing VM-based workloads on the same infrastructure. This isn’t simply running Kubernetes alongside vSphere, it’s a fully integrated experience. Administrators can deploy, scale, and manage Kubernetes clusters as easily as they manage VMs. The platform supports a range of Kubernetes deployment options, from single-node development clusters to highly available, production-grade deployments. This flexibility enables organizations to adopt a multi-cloud strategy and benefit from the agility of containers without sacrificing the stability and reliability of their established virtualization infrastructure. Furthermore, the integration extends to application lifecycle management with Aria Automation, providing consistent automation for both VM and containerized apps.

Controlling Costs:

Traditionally, managing separate infrastructure silos has led to resource fragmentation and wasted spend. VCF 9.0 addresses this by optimizing resource utilization across both VM and container workloads. Centralized management and automation capabilities reduce manual effort and improve operational efficiency. In essence, VCF 9.0 is a platform designed for the modern data center, offering a simplified, unified, and cost-effective way to build and operate a truly sovereign and secure cloud environment capable of supporting a diverse range of applications and workloads.

VMware Cloud Foundation 9.0 introduces significant advancements in storage management, fundamentally changing how organizations consume and optimize their storage infrastructure. These features aren’t merely incremental improvements; they represent a strategic shift towards maximizing storage efficiency and unlocking new levels of application performance.

vSAN Global Deduplication

A core feature is the introduction of global deduplication for vSAN. Historically, deduplication in virtualized environments has been limited by the scope of individual datastores or VMs. vSAN global deduplication operates across the entire vSAN cluster, identifying and eliminating redundant data blocks regardless of which VM or datastore they reside in. This dramatically reduces the amount of storage capacity required, resulting in significant cost savings. The benefits extend beyond simply reducing storage footprint; deduplication also improves data protection efficiency, as only unique data blocks need to be backed up and replicated. Importantly, VCF 9.0 manages the complexity of deduplication, ensuring it’s transparent to applications and administrators.

VMware Cloud Foundation 9.0 introduces a novel approach to storage optimization by dynamically repurposing unused system resources. Instead of simply allocating unused RAM as a general cache tier, VCF 9.0 focuses on efficiently managing memory bitmaps associated with inactive workloads.

Understanding Memory Bitmaps

Memory bitmaps are essentially metadata structures that track which blocks of memory are currently in use and which are available. When a virtual machine or workload becomes inactive, its memory pages may still be allocated but are not actively being used. However, those allocations still consume valuable memory resources.

How it Works: Offloading Inactive Workloads

VCF 9.0 intelligently identifies these inactive workloads represented by memory bitmaps. Instead of keeping those bitmap allocations tied up in RAM, the platform transparently offloads them to high-performance NVMe PCIe disks. This process effectively frees up valuable RAM for active workloads, improving overall system performance and responsiveness.

VMware Cloud Foundation 9.0 introduces a dramatically simplified deployment experience with its new VCF Installer, marking a significant leap forward from the complexities of previous versions. While VCF 5.2.x administrators faced a cumbersome process requiring detailed spreadsheet configuration followed by uploading to Cloud Builder – a method prone to errors and time-consuming – the VCF 9.0 Installer streamlines the entire process.

Simplified Deployment Options

VCF 9.0 supports both online and offline deployment models. Online deployment leverages a direct connection to VMware Lifecycle Manager (LCM) for automated component downloads and configuration. This offers the fastest and most streamlined experience. Offline deployment caters to environments with limited or no internet connectivity. Administrators pre-stage the necessary components on a local depot, ensuring deployment remains possible even in air-gapped environments.

The New Installer Experience

The VCF 9.0 Installer replaces the complex spreadsheet-driven approach with a guided interface which has the capabilities to export to JSON-based configuration. Administrators define their desired environment parameters in a human-readable JSON file, specifying details like ESXi versions, network settings, and storage configurations, DNS records and type of deployment single or redundant. This declarative approach ensures consistency and reduces the risk of errors.

To ensure a smooth and successful VCF 9.0 adoption, organizations should leverage the comprehensive Customer Readiness Matrix, proactively completing pre-deployment checklists and assessments, and engaging VMware Professional Services for expert guidance and support.

VCF 9.0 isn’t just the latest iteration of a platform; it’s a foundational stepping stone towards a future where on-premise private clouds are as agile, scalable, and cost-effective as their public cloud counterparts. It’s a compelling vision for the future of hybrid cloud, and VMware Cloud Foundation 9.0 is laying the groundwork to make that vision a reality.

VMware Cloud Foundation: Don’t Forget About SSO Service Accounts

by Tommy Grot May 14, 2025

written by Tommy Grot 5 minutes read

VMware Cloud Foundation (VCF) delivers a modern, automated infrastructure. A vital, but frequently neglected, element of its operation is enabling password rotations. The svc-nsx-vc-fqdn service account within the vCenter Server SSO domain and SDDC Manager. This account is critical for NSX or LCM functionality and integration between solutions, and its failure – typically due to an expired or incorrect password – can cause significant disruption to your VCF environment. This post will highlight the importance of svc-nsx-vc-fqdn, explain the impact of a failed account, and provide proactive measures to ensure its ongoing health and prevent costly outages.

Error Message – “NSX is integrated with vLCM feature of vSphere system. Cannot disable two way authentication and service account creation functionality”

Verifying Service Account with CURL

When the SDDC Manager Password Management UI displays an invalid or outdated timestamp for the svc-nsx-vc-fqdn service account, it indicates a potential synchronization issue between SDDC Manager and the underlying vCenter SSO domain. This can lead to authentication problems and network connectivity issues within your VMware Cloud Foundation environment. As illustrated below, the ‘Last Modified Date’ is incorrectly displayed as 11/10/23 1:03PM. Let’s examine this issue in more detail.

Addressing SDDC Manager UI Timestamp Discrepancies

To troubleshoot this, administrators can use the curl command to directly query the VCF SDDC API and verify the existence and timestamp of the svc-nsx-vc-fqdn object. This bypasses the SDDC Manager UI and provides a more accurate view of the account’s state.

SSH Into SDDC Manager – ( Prepare your command using your SSO account credentials. While ‘[email protected]‘ may be a default account, you must retrieve the current, rotated password using the lookup_password utility within SDDC Manager.
Elevate to root ” su – “
Run the Bearer Token curl to retrieve a access token

TOKEN=$(curl -d '{"username" : <sso_username>, "password" : "<sso_password>"}' -H "Content-Type: application/json" -X POST http://127.0.0.1/v1/tokens | jq -r '.accessToken')

Once we have gotten the Bearer Token we are now able to execute the next CURL command with syntax below:

curl -k -X GET -H "Authorization: Bearer "$TOKEN"" --insecure 'https://localhost/v1/system/credentials/service' | json_pp

So, now that we have execute the CURL command above you will get a detailed JSON API back which has all the creation times and ensuring that the SSO Service account still exists and has not disappeared even though the SDDC Manager UI is showing — or incorrect timestamp of last time it was active / updated / modified.

{
"creationTime" : 1699646593061, #This is the timestamp representing when the object was created
"credentialType" : "SSO" #This is indicating that it is apart of the SSO Domain
"entityId" : "17bd9679-a83b-485c-9b97-ac079827224d", # Unique identifier which is stored in the VCF SDDC Database.
"entityType" : "VCENTER", #Displays that this SSO object is related to vCenter
"id" : "b69362ad-c797-4689-b763-f1fc4aed5dff",
"modificationTime" : 1699646593061, #Timestamp showing when last time this object was modified
"serviceId" : "0dd05d81-6eaa-442b-9d47-fb1134ffdbe6", #This is the ID between NSX Managers and vCenter
"serviceType" : "NSXT_MANAGER",
"targetType" : "VCENTER",
"username" : "[email protected]" # Username of service account which is integrating the two solutions
}

Now that you have executed the curl command, you should see output similar to the example JSON I’m providing above, where I’m commenting on the specific API fields of interest and explaining what they mean.

As demonstrated in the JSON outputs for other credentials, the ‘secrets’ field typically contains the encoded password within the API. However, for this specific SSO Account, this field is absent, allowing us to manually set the password on both sides of vCenter and NSX and SDDC and re-establish the connection.

Remediation of Service Account

After verifying that the SSO accounts still exist within SDDC, if you attempt to rotate them using the SDDC Password Manager UI, the initial rotation will often stall at approximately 50% and present a retry or cancel popup. Waiting the 15 minutes suggested in some KB articles and then retrying will result in the process reaching 100%, followed by a rapid failure. This is due to timing differences and synchronization processes between vCenter, NSX and SDDC.

First, lets set a basic password within vCenter SSO for the “[email protected]” Set it to VMware1!VMware1! , after you hit save wait few seconds

After the password has been updated manually via vCenter Users and Groups for the “[email protected]”.

Then log into your NSX Manager – > System -> Fabric -> Compute Managers -> Edit on vCenter Object and click edit on the FQDN | IP Address, and input your svc sso account and password.

Note: Ensure that ‘Create Service Account’ is enabled and ‘Enable Trust’ is also selected. If you encounter an error during the connection process, toggle the ‘Create Service Account’ option, enter the password, save the configuration, and then re-enable the Service Account.

Finally, lets go back into the SDDC Manager -> Password Management -> Filter based on vCenter

Enter the remediated password you previously set within vCenter and NSX. Executing this operation should result in a successful completion task within a few minutes.

Now that two-way communication between vCenter and NSX has been re-established, you can resume standard operations, including enabling vLCM for baseline-controlled patching or image-based deployments.

Beyond the technical steps, this highlights the importance of treating credential management as a proactive, ongoing process. Regular audits, automated password rotation, and diligent verification using methods like the curl command we’ve explored, aren’t merely reactive fixes—they’re essential components of a robust security posture and a resilient infrastructure. Prioritizing these practices ensures that your VMware Cloud Foundation environment remains a reliable and secure foundation for your critical applications and workloads.

VMware Cloud Foundation (VCF) has revolutionized the way organizations deploy, manage, and secure their on-premises infrastructure. With the recent release of VCF 5.2, VMware continues to push the boundaries of hybrid-cloud innovation, offering enhanced features, improved scalability, and streamlined management capabilities.

One of the most significant enhancements in VCF 5.2 is the introduction of Flexible Bill of Materials (BOM), a game-changing approach to infrastructure upgrades. Gone are the days of rigid, one-size-fits-all upgrade paths; with Flexible BOM, administrators can now customize their upgrade process to meet the unique needs of their organization.

In this blog post, we’ll delve into the world of VCF 5.2 and Flexible BOM, exploring the benefits, best practices, and step-by-step procedures for a successful upgrade. Whether you’re a seasoned VCF administrator or just starting your hybrid-cloud journey, this guide will provide you with the insights and expertise needed to elevate your infrastructure to the next level

Flexible BOM Process

Downloading The Bits:

The files will be downloaded with a internet connected laptop/desktop or virtual machine.

Note: I am using “03102025” as the directory structure for this process, you can use any name you like for the folder.

First, let’s open up the Offline Bundle Utility Tool (LCM) and start preparing commands to enter, you may copy below and replace to fit your system and your credentials.

(Since, I am using windows for downloading the bundles you will want to run the LCM with out the ./lcm-bundle… as executable, so it would just be “lcm-bundle… for windows” )

lcm-bundle-transfer-util --download --manifestDownload --depotUser <email> --outputDirectory C:\03102025

lcm-bundle-transfer-util --download --bundleManifests --depotUser <email> --bundleManifestsDir C:\03102025

lcm-bundle-transfer-util --download --compatibilityMatrix --depotUser <email> --outputDirectory C:\03102025

Note: If you do not have a VXRAIL Platform, you and disregard the –pdu dell_depot_email, remove it from the syntax as below in the screenshot.

lcm-bundle-transfer-util --depotUser <email> --download productVersionCatalog --outputDirectory C:\03102025

Uploading The Bits:

Once you have downloaded all the updates and manifest files, upload them to the SDDC manager appliance. Keep all the files extracted in the /home/vcf/ directory.

For actual bundles those will be uploaded to the /nfs/vmware/vcf/nfs-mount/ due to the large size and /home/vcf/ is limited on space.

File Structure Table

Note: This will provide simplified way of uploading and ingesting the VCF files and updates following the table below.

`--bundleManifests`	/home/vcf/bundleManifests	Upload the bundleManifests directory into /home/vcf/
`--compatibilityMatrix`	/home/vcf/Compatibility/	Upload the Compatibility directory into /home/vcf/
`productVersionCatalog`	/home/vcf/	`Upload the productVersionCatalog`.json in /home/vcf/ directory
`--sourceManifestDirectory`	/home/vcf/lcm/	Upload the lcm directory into /home/vcf/

bundleManifests

./lcm-bundle-transfer-util --update --sourceManifestDirectory /home/vcf --sddcMgrFqdn FQDN --sddcMgrUser [email protected]

./lcm-bundle-transfer-util --upload --bundleManifests --bundleManifestsDir /home/vcf/

./lcm-bundle-transfer-util --update --compatibilityMatrix --inputDirectory /home/vcf --sddcMgrFqdn FQDN --sddcMgrUser [email protected]

./lcm-bundle-transfer-util --upload productVersionCatalog --inputDirectory /home/vcf --sddcMgrFqdn FQDN --sddcMgrUser [email protected]

After you have completed the above steps for updating the BOM and Products, Manifests. Next we will go to the workload domain you want to patch. Select Plan Patching -> Select the Products you want to upgrade/patch.

./lcm-bundle-transfer-util –generatePlannerFile –sddcMgrFqdn <your FQDN> –sddcMgrUser [email protected] –outputDirectory /home/vcf –domainNames vcf-m01 -p 5.2.1.0

An Example of the plannerFile.json below:

Once you have generated the file, copy it from the SDDC Manager onto your internet connected machine.

lcm-bundle-transfer-util --download --plannerFile C:\03102025\plannerFile.json --depotUser <your username for VMware Depot>

Once your bundles have been downloaded, you will want to transfer them to the system that will be upgraded. After everything is uploaded into the NFS Directory on SDDC Manager, you will want to make sure that you elevate to root by su for ingesting bundles.

Now we will go back to the SDDC Manager, upload the actual bundles into the /nfs/… share and ingest them with command below.

./lcm-bundle-transfer-util --upload --bundleDirectory /nfs/vmware/vcf/nfs-mount/03102025/

If you have a VXRAIL VCF Deployment you will want to upload the Partner Bundles with the command below:

./lcm-bundle-transfer-util --upload "uploadPartnerBundle" --bundleDirectory directory-path

Once all update bundles have been uploaded, go back to the SDDC Manager User Interface, and you should see that the Update Now button shows up and lets you proceed with the upgrade!

VMware Cloud Foundation – Memory Tiering: Optimizing Memory Utilization for Enhanced Performance

by Tommy Grot February 5, 2025

written by Tommy Grot 4 minutes read

In the ever-evolving landscape of virtualization, efficient memory management is crucial to ensuring optimal performance and resource utilization. VMware ESXi, a powerful hypervisor, introduces an innovative feature called Memory Tiering that revolutionizes how virtual machines (VMs) interact with system memory. This blog post delves into the intricacies of ESXi Memory Tiering, exploring its benefits, implementation, and real-world impact on data center operations.

NVMe PCIe Storage and Memory Tiering

High-Speed Interface: NVMe PCIe is a high-speed, low-latency storage interface designed for SSDs (Solid-State Drives). It provides significantly faster data transfer rates compared to traditional SATA-based SSDs.
Direct Access to Memory: When combined with Memory Tiering, NVMe storage allows direct access to the host’s system memory (RAM) over the PCIe bus. This bypasses the traditional storage controller, resulting in even lower latency and higher throughput for memory operations.
Performance Benefits: With NVMe, the slower tier of memory (e.g., SSDs or persistent memory) can still offer decent performance. This is because NVMe SSDs have much faster read/write speeds, enabling quicker movement of pages between tiers.

Why NVMe Matters for Memory Tiering

Reduced Latency: Lower latency access to storage means faster page movement and improved overall system responsiveness, which are crucial for time-sensitive applications.
High Throughput: NVMe SSDs offer higher data transfer rates, enabling efficient handling of large memory pages and bulk data transfers during VM operations.
Cost-Effectiveness: By utilizing NVMe storage in the slower tiers, organizations can achieve cost savings while maintaining high performance for critical workloads.

Best Practices

Storage Configuration: Ensure that the ESXi host has the necessary PCIe slots and support for NVMe devices. Properly configure the storage to align with memory tier requirements.
Performance Monitoring: Continuously monitor VM performance and memory utilization to fine-tune Memory Tiering policies and ensure optimal page placement.
Hardware Compatibility: Verify that all hardware components, including memory modules, storage drives, and PCIe cards, are compatible with NVMe to avoid performance bottlenecks.

The integration of NVMe PCIe storage enhances VMware ESXi Memory Tiering’s capabilities, making it a powerful solution for data centers seeking to maximize memory utilization and application performance.

How To Configure Memory Tiering:

SSH into Each ESXi Host, If you ESXi Hosts are managed by VCF/SDDC Manager, you will need to lookup the password in SDDC Manager.

Enable Memory Tiering with the command below, if you want to revert and disable it set it back to FALSE and put it in maintenance mode / reboot the host.

esxcli system settings kernel set -s MemoryTiering -v TRUE

Choose the NVMe device to use as tiered memory and note the NVMe device path (i.e. /vmfs/devices/disks/).

Locate the NVMe Disk which mine is below as an example

esxcli system tierdevice create -d /vmfs/devices/disks/t10.NVMe____INTEL_SSDPED1D280GAH____________________000142FC3BE4D25C

Create the tier partition on the NVMe device. esxcli system tierdevice create -d /vmfs/devices/disks/

esxcli system settings advanced set -o /Mem/TierNvmePct -i 200

Go to -> Configure under the host -> Advanced System Settings – Filter For Mem.TierNvmePct

This is where you will set the percentage of NVMe will be set for its ratio configure that specific host

Configuring the DRAM to NVMe Ratio

As noted in the NVMe Device Recommendations section, by default, hosts are configured to
use a DRAM to NVMe ratio of 4:1. This can be configured per host to evaluate performance
when using different ratios.
The host advanced setting for Mem.TierNvmePct sets the amount of NVMe to be used as
tiered memory using a percentage equivalent of the total amount of DRAM. A host reboot is
required for any changes to this setting to take effect.
For example, setting a value to 25 would configure using an amount of NVMe as tiered memory
that is equivalent to 25% of the total amount of DRAM. This is known as the DRAM to NVMe
ratio of 4:1. A host with 1 TB of DRAM would use 256 GB of NVMe as tiered memory.
Another example, setting this value to 50 would configure using an amount of NVMe as tiered
memory that is equivalent to 50% of the total amount of DRAM. This is known as the DRAM to
NVMe ratio of 2:1. A host with 1 TB of DRAM would use 512 GB of NVMe as tiered memory.
One last example, setting this value to 100 would configure using an amount of NVMe as tiered
memory that is equivalent to 100% of the total amount of DRAM. This is known as the DRAM to
NVMe ratio of 1:1. A host with 1 TB of DRAM would use 1 TB of NVMe as tiered memory.
It is recommended that the amount of NVMe configured as tiered memory does not exceed the
total amount of DRAM.
