You are designing a FlexPod solution with secure multitenancy for a company. Each department in the company wants to use their own storage and to be…

To meet the design requirements for a secure, multi-tenant FlexPod solution with departmental storage and Active Directory integration, three key NetApp ONTAP technologies are essential.

1. Storage Virtual Machine (SVM): The SVM is the fundamental ONTAP construct for multitenancy. It creates a secure, isolated virtual storage server for each department, with its own dedicated data volumes, network interfaces (LIFs), and administrative credentials.

2. CIFS: The Common Internet File System (CIFS/SMB) protocol is required to provide file-level access for Windows clients and to integrate directly with Windows Active Directory for user authentication and authorization, fulfilling a core requirement.

3. IPspaces: To ensure secure network multitenancy, IPspaces are used to create distinct IP network domains. This allows different SVMs (departments) to have isolated network configurations, preventing IP address conflicts and ensuring that network traffic for one tenant is segregated from another.

B. NVMe: NVMe is a high-performance protocol for accessing flash storage media; it is irrelevant to logical data separation, multitenancy, or Active Directory integration.

C. S3: S3 is an object storage protocol. The requirement for Windows Active Directory integration specifically implies a file-based protocol like CIFS, not object storage.

1. Storage Virtual Machine (SVM): NetApp ONTAP 9 Documentation, "System administration concepts," Section: "Storage virtual machines." This section states, "A Storage Virtual Machine (SVM) is a logical storage server that contains data volumes and one or more network logical interfaces (LIFs)... SVMs provide isolation between tenants in a multitenant environment."

2. CIFS: NetApp ONTAP 9 Documentation, "SMB/CIFS management," Section: "How the CIFS server works with Active Directory." This document explains, "When you create a CIFS server on the Storage Virtual Machine (SVM), you can specify the Active Directory domain that the CIFS server will join for user authentication."

3. IPspaces: NetApp ONTAP 9 Documentation, "Network management," Section: "What IPspaces are." This source clarifies, "IPspaces enable you to partition the cluster's IP network into distinct, non-overlapping IP network domains... This is useful for service providers who must create separate network domains for different customers." This directly applies to creating secure, separate domains for different departments (tenants).

4. NetApp Technical Report 4714: "Securing Data on NetApp ONTAP 9," Section 2.1 "Secure Multi-Tenancy." This report details the architecture for secure multitenancy, stating, "ONTAP provides secure multi-tenancy by using a combination of SVMs, IPspaces, and role-based access control (RBAC)." This confirms the combined use of these specific technologies for the required solution.
