How many VPCs are required to deploy CVO in Google Cloud?

A standard deployment of NetApp Cloud Volumes ONTAP (CVO) in Google Cloud requires two Virtual Private Clouds (VPCs). The first VPC is for the Cloud Manager instance, which serves as the management and orchestration plane for CVO. The second VPC is dedicated to the Cloud Volumes ONTAP instance itself, which handles the data plane operations. This separation is a documented best practice that provides essential network isolation and security between the management and data traffic, ensuring a robust and secure cloud storage environment.

A. 4: This is incorrect. A standard single-node or HA pair deployment of CVO does not require four separate VPCs; this would introduce unnecessary network complexity.

B. 6: This is incorrect. Six VPCs are significantly more than what is required for the core deployment and management of a CVO system.

D. 3: This is incorrect. While additional VPCs might be used for client access or other services, the fundamental requirement for deploying and managing CVO is two VPCs.

1. NetApp Cloud Documentation, "Get started with Cloud Volumes ONTAP in Google Cloud": In the "Networking requirements for Google Cloud" section, the documentation outlines the need for separate network environments. It states, "Cloud Manager needs to be installed in Google Cloud. It requires its own VPC network and firewall rules." and "You'll need a VPC and subnets for Cloud Volumes ONTAP... It's a best practice to deploy Cloud Volumes ONTAP in its own VPC." This explicitly details the requirement for two VPCs.

2. NetApp Technical Report TR-4719, "Cloud Volumes ONTAP for Google Cloud Platform Architecture and Deployment Guide": Section 3, "Networking," provides architectural diagrams and descriptions. Figure 2, "Cloud Volumes ONTAP for Google Cloud Platform architecture," clearly depicts a "Management VPC" hosting the OnCommand Cloud Manager (now Cloud Manager) and a separate "Data VPC" hosting the Cloud Volumes ONTAP instance. This visual and descriptive separation reinforces the two-VPC model.
