VMware Cloud Foundation (VCF) Brownfield Deployments

VMware Cloud Foundation (VCF) provides a unified platform for managing hybrid clouds, but the deployment process differs between Greenfield (new) and Brownfield (existing) environments. Brownfield deployment involves integrating pre-existing infrastructure into the VCF framework.

Preparing to Use the VCF Import Tool

The VCF Import Tool is essential for transitioning existing infrastructure into the VCF framework. Here’s a step-by-step guide to preparing the tool:

  1. Download the Necessary Files:
    • SDDC Manager OVA: The foundation for managing VCF.
    • VCF Import Tool: Enables import and integration of existing infrastructure.
    • NSX Install Bundle: Configures the networking components for VCF.
  2. Deploy SDDC Manager:
    • This step is necessary for “convert” use cases to establish centralized management within VCF.
  3. Extract the Import Tool:
    • Transfer and configure the import scripts within the SDDC Manager.
  4. Copy NSX Bundle:
    • Ensure the NSX configuration is uploaded for seamless network integration.

Convert Workflow: Transitioning Infrastructure to VCF

The Convert Workflow addresses the challenge of adapting existing environments to align with VCF’s architecture. Follow these steps:

  1. Verify Prerequisites:
    • Confirm that SDDC Manager is running version 5.2 or later.
    • Ensure all required files (Import Tool, NSX bundles) are uploaded.
  2. Run Pre-Check Scripts:
    • Validate the current environment using the Import Tool’s pre-check capabilities. This step identifies configuration issues or incompatibilities.
  3. Create NSX JSON:
    • Generate a JSON file to map the existing network configurations into VCF’s NSX environment.
  4. Convert Management Domain:
    • This final step transitions the management domain to align with VCF’s integrated control and automation.

Import Workflow: Integrating Existing Components

For specific components or domains, the Import Workflow provides a framework to incorporate them into VCF:

  1. Check Prerequisites:
    • Confirm readiness by ensuring the infrastructure meets the required configurations.
  2. Generate NSX JSON:
    • Map existing NSX configurations into a JSON format suitable for VCF integration.
  3. Import Workload Domains:
    • Import and integrate vSphere and NSX components into the VCF ecosystem.

Sync Workflow: Maintaining Infrastructure Alignment

The Sync Workflow ensures continued alignment between the existing infrastructure and VCF:

  1. Verify Prerequisites:
    • Confirm that SDDC Manager is operational and all required scripts are present.
  2. Sync Workload Domain:
    • Synchronize the workload domains with VCF’s management systems, ensuring consistency and reliability.

VCF Import Tool Options and Parameters

Below is an overview of the key actions and parameters available in the VCF Import Tool:

1. Help and Version Commands

  • -h, --help
    Displays the help menu for the VCF Import Tool, outlining available commands and their usage.
  • -v, --version
    Shows the current version of the VCF Import Tool.

2. Core Actions for Brownfield Deployments

  • convert
    Converts an existing vSphere infrastructure into a management domain within SDDC Manager.
  • check
    Validates if a vCenter is suitable for import as a workload domain in SDDC Manager.
  • import
    Imports an existing vCenter as a VI workload domain into SDDC Manager.

3. Sync and Deployment Operations

  • sync
    Synchronizes configuration between an imported VI workload domain or a workload domain deployed from SDDC Manager. This helps manage configuration drift between vCenter Server and SDDC Manager.
  • deploy-nsx
    Deploys NSX Manager as a standalone operation. This is useful for preparing networking configurations for workload domains.
  • precheck
    Runs validation checks on a vCenter to identify any potential issues before starting the import or conversion process.

Demystifying Distributed Security in VMware Cloud Foundation

In today’s evolving IT landscape, securing distributed environments is crucial. VMware Cloud Foundation (VCF) addresses these challenges head-on with its Distributed Security model. During the VMware Explore EU 2024 session titled “Demystifying Distributed Security in VMware Cloud Foundation,” experts Chris McCain, Tim Burkard explored the nuances of enhancing security within VCF environments.

Key NOTES:

  1. vDefend Distributed Protection:
    • This is VMware’s approach to ensuring secure communication between virtual machines (VMs) by enforcing strict security rules. The Distributed Firewall (DFW) policies, integral to vDefend, apply a Zero Trust model, allowing only authorized traffic and rejecting any unauthorized attempts.
  2. Granular Security Policies:
    • VCF’s Distributed Firewall offers granular control over security policies, allowing IT teams to define rules at both policy and individual VM levels. This flexibility ensures that security is tightly integrated into every layer of the infrastructure.
  3. Intrusion Detection and Prevention:
    • VMware’s Distributed Intrusion Detection and Prevention (IDP) system proactively monitors and prevents unauthorized activities. The IDP uses an extensive signature database to alert or block threats, ensuring real-time protection across the data center.
  4. Built-in Tools for Validation and Troubleshooting:
    • Tools like Traceflow and Live Traffic Analysis are pivotal for monitoring and validating security rules. These tools help IT professionals ensure that the DFW is functioning as intended and that traffic flow complies with security policies.

ESXi Hosts: The Data Plane

ESXi hosts, where VMs reside, are integral to enforcing NSX DFW rules. The following CLI commands can be run on ESXi hosts to manage and troubleshoot DFW settings at the host level:

  • List All the VMs dvFilter Names: Use summarize-dvfilter to list all dvFilters associated with VMs. dvFilters are kernel modules that apply firewall rules to VMs’ network traffic.
  • View IP and MAC Addresses for a dvFilter: To see the IP and MAC addresses related to a specific dvFilter, the command is
    vsipioctl getaddrsets -f <dvfilter-name>
  • List the Firewall Rules Applied on DvFilter: Retrieve the set of firewall rules applied to a dvFilter by executing
    vsipioctl getrules -f <dvfilter-name>
  • View Firewall Configuration for a dvFilter: To inspect the firewall configuration for a specific dvFilter, the command is
    vsipioctl getfwconfig -f <dvfilter-name>
