Architecture Overview

This design references three configurations for the on-premises deployment: General Purpose, Compute Optimized, and Storage Optimized.  The software is the same across all three with changes made to the following components: higher core count CPU and increased RAM on Compute Optimized; and external storage to scale out capacity outside of compute on Storage Optimized.  These configurations are recommended starting points and not a strict requirement or limitation.  Please review Lenovo’s VMware-certified components to customize configurations as needed.  Microsoft Azure will be the hybrid cloud for this reference architecture.

VMware Cloud Foundation Architecture Conceptual Design

VMware Cloud Foundation (VCF) can be deployed in two architectures: Standard & Consolidated.

The Standard Architecture (Figure 1) consists of a Management Domain, which is an independent vSphere cluster with its own vCenter and NSX Manager cluster, where the management components will be physically separated from the workload VMs.  The management components consist of SDDC Manager, all vCenter Servers for both management and workloads, NSX Manager clusters for both management and workloads, and NSX Edge cluster(s) for management only.  Additional VI Workload Domains can be deployed consisting of their own compute cluster(s), NSX Management cluster(s) (hosted in the Management Domain), separate vCenter(s), and a separate NSX edge cluster(s), leveraging vSAN as the storage.  Though vSAN is required for the Management Domain, Workload Domains support the option to leverage vSAN, NFS, or Fibre Channel as the shared storage in the cluster.

Each “domain” is a physically separate vSphere cluster.  This ensures there is no resource contention for the management components of the environment.  For simplicity, Lenovo XClarity depicted in Figures 1-5 represents both Lenovo XClarity Administrator and Lenovo XClarity Integrator for VMware vCenter.

Figure 1: Standard Architecture conceptual design
The Consolidated Architecture (Figure 2) deploys the same components, but all within a single physical cluster.  The management components are logically protected inside a management resource pool.  This is one of the key differences between the Standard Architecture and the Consolidated Architecture, as there are no resource pools in the Standard Architecture since no workload VMs should be deployed in the management domain.

Figure 2: Consolidated Architecture conceptual design

Customers may choose to deploy additional vSphere clusters within the Consolidated Architecture, as well as expand the environment by adding additional VI Workload Domains similar to the Standard Architecture.

Each additional VI Workload Domain that is created with its own vCenter joins the Management Domain’s SSO domain.  This ensures a single pane of glass to manage all Workload Domains, and also provides the ability to limit access through Role Based Access Control for specific users, or groups of users, to their respective Workload Domain.

Physical Design

This reference architecture will cover, at a high level, three configurations of the physical components.  Two of these configurations relate to the amount of compute in the physical server (General Purpose and Compute Optimized), both leveraging the Consolidated Architecture, and one with external storage (Storage Optimized) in a Standard Architecture.

General Purpose

The General-Purpose configuration (Figure 3) is a baseline that serves as a starting point for general purpose workloads in any environment.  This configuration consists of a VCF Consolidated Architecture where the management & infrastructure VMs run in the same physical cluster as the workload VMs.  The two components are separated into their own Resource Pools to provide a level of separation to avoid resource contention.

Figure 3: General Purpose conceptual design

Compute Optimized

The Compute Optimized configuration (Figure 4) follows the model of the General-Purpose configuration but increases the core count from 16 cores per CPU to 24, as well as doubles the amount of RAM per server from 384GB to 768GB.  This configuration is an example for workloads that may consist of larger VMs that are CPU intensive or require data to live in memory of the VM.

Storage Optimized

The Storage Optimized configuration (Figure 5) includes the same hardware & software components as the General Purpose configuration, but leverages VCF’s Standard Architecture consisting of a separate Management Domain where all management & infrastructure VMs will run, while adding a separate Workload Domain that is dedicated to all workload VMs.  This configuration adds the ability to scale out storage decoupled from compute by including external storage with the Lenovo ThinkSystem DM5000H unified hybrid storage system.

Incorporating the SaaS version of VMware Aria offers several advantages that significantly reduce overhead and streamline operations for vSphere administrators. One of the key benefits is the reduction in manual administrative tasks related to updates and enhancements. With the SaaS version of VMware Aria, updates, including feature enhancements and bug fixes, are automatically and regularly rolled out by VMware. As a result, vSphere admins no longer need to allocate time and effort to apply updates, ensuring that the environment remains up-to-date with the latest improvements without any additional burden on their part.

Furthermore, the SaaS version of VMware Aria provides a unified and centralized management platform, acting as a single pane of glass for visibility and control over the entire hybrid cloud environment. This comprehensive view enables administrators to monitor and manage various components, applications, and workloads across both on-premises and cloud-based resources from a centralized dashboard. This centralized approach simplifies the management process, streamlines troubleshooting, and enhances overall efficiency, as vSphere admins can quickly access critical information and perform necessary tasks without switching between multiple interfaces.

Deploying VMware Aria SaaS involves simply deploying a cloud proxy each for VMware Aria Automation and VMware Aria Operations (Figure 21).  These cloud proxies facilitate the communication, orchestration, and data collection across many aspects of the on-premises environment.

Use Cases

Hybrid cloud solutions offer various benefits and use cases that cater to diverse business requirements. Here are a few examples:

Disaster Recovery and Business Continuity

One of the primary use cases for a hybrid cloud is to implement a robust disaster recovery strategy. By replicating critical workloads and data between on-premises infrastructure and the cloud, organizations can ensure business continuity in the event of a disaster, such as hardware failure, natural calamities, or cyberattacks. The hybrid cloud provides an ideal platform for cost-effective and reliable data replication and failover solutions.

Data Backup and Archiving

Hybrid cloud solutions offer an excellent way to manage data backup and long-term archiving. Organizations can store critical data on-premises for fast access and use the cloud for cost-effective, scalable, and reliable data archival. This approach ensures data redundancy, compliance adherence, and efficient management of large datasets.

Veeam is a comprehensive data backup and archive tool designed to work with VMware workloads, offering robust disaster recovery capabilities. With its Microsoft Azure plugin, Veeam seamlessly integrates with Azure cloud services, enabling users to efficiently manage and protect their virtualized environments across on-premises and cloud infrastructures. This combination of features ensures reliable data protection, simplified recovery processes, and enhanced business continuity for organizations utilizing VMware and Microsoft Azure.  For additional information regarding the Microsoft Azure Plug-In for Veeam Backup & Replication, please visit

Lenovo recently introduced a reference architecture enhancing data protection and management capabilities. By integrating Veeam backup solutions with the robust ThinkSystems DM storage and the ThinkAgile VX series hyperconverged solution, users can now benefit from a seamless and optimized backup experience. This collaboration ensures that data integrity and availability are maximized, providing enterprises with a powerful solution to safeguard their critical information effectively.  For additional information, see the reference architecture here:

Scalability and Bursting

Hybrid cloud environments allow businesses to address fluctuating demands and varying workloads effectively. When on-premises resources reach their capacity, organizations can "burst" into the public cloud, leveraging its virtually limitless scalability to handle peak loads. This elasticity ensures efficient resource utilization, cost optimization, and improved performance during peak periods.

DevOps and Testing

The hybrid cloud is well-suited for DevOps practices and software development testing. Developers can deploy and test applications in the cloud without interfering with the production environment. This separation of development and production environments improves collaboration, accelerates development cycles, and minimizes risks associated with changes.

Geographic Reach and Data Sovereignty

Hybrid cloud solutions provide the ability to deploy applications and services in geographically dispersed data centers, complying with data sovereignty regulations and improving latency for regional users. This use case is particularly relevant for global organizations seeking to deliver low-latency experiences and adhere to data residency requirements.
