You decide on the life cycle management of the NSX-T Data Center components according to the amount of time and effort to perform a deployment, upgrade, or patch operation. You also consider the impact such an operation has on the management solutions that are connected to NSX-T Data Center for the management domain.

Life Cycle Management in a Deployment with a Single Region and with Multiple Availability Zones

Life cycle management of NSX-T Data Center involves the process of applying patches, updates or upgrades to the NSX-T Data Center appliances and hypervisor components.

In a typical environment, you perform life cycle management by using the Upgrade Coordinator which is a service in NSX-T Manager. When you implement a solution by using VMware Cloud Foundation, you use SDDC Manager for life cycle management where additional components, such as automatic patching, upgrade, and product compatibility verification, are included as part of the life cycle management process.

Design Implication

SDDC-MGMT-VI-SDN-051

Use SDDC Manager to perform the life cycle management of NSX-T Manager and related components in the management domain.

Because the deployment scope of SDDC Manager covers the full SDDC stack, SDDC Manager performs patching, update, or upgrade of the management domain as a single process.

The operations team must understand and be aware of the impact of a patch, update, or upgrade operation by using SDDC Manager.

Life Cycle Management in Multi-Region Deployment

In a multi-region deployment, the NSX-T Global Manager and NSX-T instances in the individual workload domains must be compatible and supported version with each other both during the upgrade and post-upgrade. To manage the life cycle of NSX-T Global Manager, use the Upgrade Coordinator on the the NSX-T Global Manager appliances. The version of SDDC Manager in this design does not handle the life cycle of NSX-T Global Manager nodes. For the NSX-T Local Manager appliances, you continue using SDDC Manager.

Design Implication

SDDC-MGMT-VI-SDN-052

For a dual-region SDDC, use NSX-T Upgrade Coordinator to perform Perform life cycle management on the NSX-T Global Manager appliances.

The version of SDDC Manager in this design is not currently capable of life cycle operations (patching, update, or upgrade) for NSX-T Global Manager.

You must always align the version of the NSX-T Global Manager nodes with the rest of the SDDC stack in VMware Cloud Foundation.

You must explicitly plan upgrades of the NSX-T Global Manager nodes. An upgrade of the NSX-T Global Manager nodes might require a cascading upgrade of the NSX-T Local Manager nodes and underlying SDDC Manager infrastructure prior to the upgrade of the NSX-T Global Manager nodes.

SDDC-MGMT-VI-SDN-053

For a dual-region SDDC, establish an operations practice to ensure that prior to the upgrade of any workload domain, the impact of any version upgrades is evaluated regarding the need to upgrade NSX-T Global Manager.

The versions of NSX-T Global Manager and NSX-T Local Manager nodes must be compatible with each other.

Because the version of SDDC Manager in this design does not provide of life cycle operations (patching, update, or upgrade) for the NSX-T Global Manager nodes, upgrade to an unsupported version cannot be prevented.

The administrator must establish and follow an operational practice by using a runbook or automated process to ensure a fully supported and compliant bill of materials prior to any upgrade operation.

SDDC-MGMT-VI-SDN-054

For a dual-region SDDC, establish an operations practice to ensure that prior to the upgrade of the NSX-T Global Manager, the impact of any version change is evaluated against the existing NSX-T Local Manager nodes and workload domains.

The versions of NSX-T Global Manager and NSX-T Local Manager nodes must be compatible with each other.

Because the version of SDDC Manager in this design does not provide of life cycle operations (patching, update, or upgrade) for the NSX-T Global Manager nodes, upgrade to an unsupported version cannot be prevented.

The administrator must establish and follow an operational practice by using a runbook or automated process to ensure a fully supported and compliant bill of materials prior to any upgrade operation.
