18.2 Planning for File Services

Functional overviews of each file service product are included in Section 18.1, Overview of File Services.

18.2.1 Deciding Which Components Match Your Needs

To decide which file service components to install, you should match service features listed in Table 18-8 to your network’s file service requirements.

  • Linux POSIX file system on OES server

  • NSS volumes

  • Secure LDAP Authentication

18.2.2 Comparing Your CIFS File Service Options

OES offers three file services that use the CIFS protocol: Novell CIFS, Novell Samba, and Samba in Domain Services for Windows (DSfW).

Authentication

A Password policy that allows the CIFS proxy user to retrieve passwords is required.

A Samba-compatible Password policy is required for compatibility with Windows workgroup authentication.

The Domain Services Password policy is required for DSfW users. The domain is set up as a trusted environment.

DSfW uses Active Directory authentication methods, such as Kerberos, to ensure that only authorized users can log in to the domain.

File system support

NSS is the only file system supported for this release.

It is recommended (but not required) that you create Samba shares on NSS data volumes.

NSS is fully integrated with eDirectory for easier management, and using an NSS volume allows you to take advantage of the rich data security model in NSS. You can use either iManager or the nssmu utility to create an NSS volume on an OES server. For instructions on how to set up an NSS volume, see Managing NSS Volumes in the OES 11 SP2: File Systems Management Guide.

LUM and Samba enablement

LUM and Samba enablement are not required.

Users must be enabled for LUM and Samba and assigned to a Samba group.

eDirectory users in the domain (eDirectory partition) are automatically Samba users and are enabled to access Samba shares. See Creating Users in the OES 11 SP2: Domain Services for Windows Administration Guide.

Domain users are set up with the necessary UID and default group (DomainUsers) membership.

Every additional eDirectory group created within the domain is automatically Linux-enabled.

Username and password

The same username and password must exist on both the Windows workstation and in eDirectory.

The same username and password must exist on both the Windows workstation and in eDirectory.

eDirectory users in the domain (eDirectory partition) can log into any workstation that has joined the domain. There is no need for a corresponding user object on the workstation.

18.2.3 Planning Your File Services

  1. For the file services you plan to install, compute the total additional RAM required (above the basic system requirement).

    • NCP: There are no additional RAM requirements.

    • NetStorage: There are no additional RAM requirements.

    • Novell AFP: There are no additional RAM requirements.

    • Novell CIFS: There are no additional RAM requirements.

    • Novell iFolder 3.9.2: Suggestions for calculating the additional RAM you need are contained in Server Workload Considerations in the Novell iFolder 3.9.2 Administration Guide.

    • Samba: There are no additional RAM requirements.

  2. Record the additional required RAM in your planning notes.

  3. For the file services you plan to install, compute the total additional disk space required (above the basic system requirement).

    • NCP: Allocate enough disk space to meet your users’ file storage needs. On Linux, this space must exist on partitions you have designated as NCP volumes.

    • NetStorage: There are no disk space requirements because NetStorage provides access only to other file storage services.

    • Novell AFP: Allocate enough disk space for the partition containing the /home directories to meet your users’ file storage needs.

    • Novell CIFS: Allocate enough disk space for the partition containing the /home directories to meet your users’ file storage needs.

    • Novell iFolder 3.9.2: Suggestions for calculating the additional disk space you need are contained in Server Workload Considerations in the Novell iFolder 3.9.2 Administration Guide.

    • Samba: Allocate enough disk space for the partition containing the /home directories to meet your users’ file storage needs.

  4. Record the additional required disk space in your planning notes.

  5. For the file services you plan to install, refer to the information in the sections of the OES 11 SP2 installation guide that are indicated in the following table.

    Note your planning choices on your planning sheet.
