System Overview Environment Scenarios The NAS server is deployed in one of two security modes: ■ Workgroup ■ Domain (Windows NT Domain or Active Directory Domain) The NAS server uses standard Windows user and group administration methods in each of these environments. For procedural instructions on managing users and groups, see Chapter 6 of this guide. Regardless of the deployment, the NAS server integrates easily into multiprotocol environments, supporting a wide variety of clients. The following protocols are supported: ■ Distributed File System (DFS) ■ Network File System (NFS) ■ Hypertext Transfer Protocol (HTTP) ■ File Transfer Protocol (FTP) ■ Microsoft Server Message Block (SMB) Workgroup In a workgroup environment, users and groups are stored and managed separately, on each member server of the workgroup. Workgroups are typical for very small deployments where little or no computing environment planning is required. Note: In a clustered deployment, the clusters must be members of a domain. Therefore, workgroup environments are supported only in non-clustered deployments. Domain When operating in a Windows NT or Active Directory domain environment, the NAS server is a member of the domain and the domain controller is the repository of all account information. Client machines are also members of the domain and users log on to the domain through their Windows based client machines. The domain controller also administers user accounts and appropriate access levels to resources that are a part of the domain. Additional information about planning for domain environments can be found at: http://www.microsoft.com/windowsserver2003/technologies/directory/activedirectory/default.mspx The NAS server obtains user account information from the domain controller when deployed in a domain environment. The NAS server itself cannot act as a domain controller, backup domain controller, or the root of an Active Directory tree as these functions are disabled in the operating system. 26 NAS 4000s and 9000s Administration Guide
