3.4 Which OES Platform Is Best for My Services?

You have already seen that there are differences in the way OES provides services on SLES 9 and NetWare 6.5 (See Section 3.2, What Services Are Included in OES?.) To help you better assess which OES platform can best meet your network service needs, you should consider the inherent platform strengths of Linux and NetWare and the differences in the service offerings on each platform.

3.4.1 Platform Strengths

Although both OES platforms provide a full set of network services, there are differences in the NetWare and Linux platforms.

Table 3-2 Platform Comparison

OES NetWare

SUSE LINUX Enterprise Server 9

Brief description

Novell's award-winning network-optimized operating system.

Novell's award-winning Linux operating system.

Industry-recognized strengths

  • Reliability

  • Scalability

  • Security

  • Open application environment

  • Flexibility

  • Versatility

Business value propositions

NetWare excels when the user population and management burden is highly distributed:

  • Increases network availability.

  • Optimizes manageability.

  • Enhances user productivity.

  • Runs Apache, Tomcat, MySQL, and other open source applications.

SLES 9 is well suited as an application server running Linux-based solutions:

  • Runs thousands of programs available from the open source community.

  • Delivers OES file and print services.

  • Hosts open source Web servers, proxy servers, and mail servers.

3.4.2 Service Differences on the OES Platforms

In addition to considering the platform strengths, you should understand the differences in the features available when services are running on Linux or NetWare. The following examples illustrate this point.

  • DHS/DHCP: NetWare DNS/DHCP services are far richer than the basic DNS/DHCP functionality available in the standard Linux implementation.

    Many organizations find Linux DNS/DHCP services to be completely adequate. On the other hand, some organizations—especially those that currently leverage the advanced services available on NetWare—might be frustrated with the Linux implementation of DNS/DHCP and find it inadequate for their needs.

  • Novell Storage Services (NSS): When deploying NSS, you might want support for Novell Distributed File Services (DFS) so you can move or split NSS volumes. This feature is currently available only on NSS running on NetWare.

You should fully investigate any service differences between platforms before you finalize your service/platform choices.

It is beyond the scope of this guide to explain every point that might be important to you as you plan your network services. For this level of information, you should consult the service-specific manuals and guides provided in the OES online documentation.

To help you, Table 3-3 indicates which services are the same, contains links to documentation sections that discuss service differences, and shows which services are unavailable on a given platform.

Samba

Linux solution for CIFS file access. NetWare provides CIFS access through the Native File Access Protocol (NFAP) functionality.

For more information, see the Samba Administration Guide for OES Linux SP2 .

Search (QuickFinder)

When indexing a file system, the QuickFinder engine indexes only what it has rights to see.

On NetWare, it has full access to all mounted volumes. On Linux, it has rights to only the files that the novlwww user in the www group has rights to see.

For more information, see Security Characteristics and Generating an Index For a Linux-mounted NSS Volume in the QuickFinder Server 4.2 Administration Guide .

Server resource management (eDirectory)

eDirectory on NetWare manages server resources. For example, you can view and modify file system information, manage files and folders on NetWare volumes, salvage and purge deleted files, allocate volume space, and create objects to facilitate file management. See Managing Objects in the Novell eDirectory 8.7.3 Administration Guide .

The current version of eDirectory for Linux does not support management of server resources.

SLP (Novell SLP) (OpenSLP)

OpenSLP Services on Linux

Implementing the Service Location Protocol

NetWare uses Novell SLP by default, which provides synchronization between Directory Agents (DAs) that are in the same eDirectory context. This provides service information beyond the local network.

Alternatively, you can implement OpenSLP for eDirectory. Be aware, however, that DA synchronization is not supported in OpenSLP.

OpenSLP on Linux is not customized to provide DA synchronization.
