The initial release of NSX-T on VxBlock 1000 enables customers to satisfy some of the most basic and embryonic use cases immediately. Examples include:
- Software-defined Layer 2 Data-Center Scale using the GENEVE overlay
- Software-backed failure domain isolation
- NSX-T micro-segmentation
- Ingestion by upper stack cloud management platforms for IaaS automation
The architecture allows customers to explore the full extent of the NSX-T offering while retaining the assurance of a fully engineered platform at the back end. These features can be broadly categorized as follows, together with some examples:
- Networking — GENEVE Overlay and Layer 2/3 DC Scale, Failure Domain Isolation
- Security — Edge Firewall, Micro-segmentation, Service Insertion.
- Automation — API Network provision, integration with VxBlock Central, consumption by IaaS platforms such as vRealize Automation
- Visibility — vRNI, vROps and NSX Intelligence

So far we have identified some key use cases and provided a high-level overview of how the NSX-T Management, Control, and Data Planes are designed. We have not yet examined how the individual components knit together to deliver tangible business, operational, and technical benefits. To illustrate this, the following diagram uses an elevated view architecture to show how even a minimal single system — a single-site NSX-T deployment on VxBlock — can provide tangible beneficial outcomes.

This figure shows:
- How the NSX-T Management, Control, and Data Planes are integrated into the VxBlock 1000 platform
- By what mechanism the planes are consumed
- Which initial Day 0 use cases are serviced
- How these use cases can be expanded upon as VxBlock 1000 and VMware NSX-T evolve over time
Although Figure 7 goes into relative depth, some low-level detail is excluded for the sake of conciseness and clarity. For a complete in-depth architectural review of NSX-T on VxBlock, see Architectural Overview of NSX-T on VxBlock 1000 (to be published May, 2020).
