1.0 Planning for SUSE Linux Enterprise

The implementation of an operating system either in an existing IT environment or as a completely new rollout must be carefully prepared. With SUSE Linux Enterprise 10, get a variety of new features. It is impossible to describe all the new features here. The following is just a list of major enhancements that might be of interest.

Xen 3.x Virtualization

Runs many virtual machines on a single server, each with its own instance of an operating system. For more information about this technology, see the virtualization manual on http://www.novell.com/documentation/sles10/index.html.

YaST

Several new configuration options have been developed for YaST. These are normally described in the chapters about the technology involved.

CIM Management with openWBEM

The Common Information Model Object Manager (CIMON) is a Web-based enterprise management utility. It provides a mature management framework. See also Section 11.0, OpenWBEM.

SPident

The management utility SPident gives an overview of the installed software base and clarifies the current service pack level of the system.

Directory Services

Several LDAP-compliant directory services are available:

  • Microsoft Active Directory

  • OpenLDAP

Novell AppArmor

Harden your System with the Novell AppArmor technology. This service is described in depth in , (↑ Novell AppArmor Administration Guide ).

iSCSI

iSCSI provides an easy and reasonably inexpensive solution for connecting Linux computers to central storage systems. Find more information about iSCSI in Section 12.0, Mass Storage over IP Networks—iSCSI.

Network File System v4

Starting with version 10, SUSE Linux Enterprise supports NFS also in version 4. This gives you performance improvements, strong security, and a stateful protocol. See also Section 38.0, Sharing File Systems with NFS.

Oracle Cluster File System 2

OCFS2 is a general-purpose journaling file system that is fully integrated in the Linux 2.6 kernel and later. Find an overview of OCFS2 in Section 14.0, Oracle Cluster File System 2.

Heartbeat 2

Heartbeat 2 provides a cluster membership and messaging infrastructure. The setup of such a cluster is described in the Heartbeat Guide.

Multipath I/O

Device mapping multipath IO features automatic configuration of the subsystem for a large variety of setups. For details, see the chapter about multipath I/O in Storage Administration Guide.

Linux Kernel Crash Dump

Debugging kernel-related problems is now much more comfortable when using Kexec and Kdump. This technology is available on x86, AMD64, Intel 64, and POWER platforms.
