1.10 Data Consolidation

Your storage solution must allow you to reorganize and consolidate storage resources to improve manageability and to lower costs. For example, you can consolidate NetWare servers, applications, and operations into an OES 11 cluster built with commodity components (such as iSCSI SANs, storage subsystems, and IP networks) to help lower costs.

For many organizations, the first step in a business continuity plan or disaster recovery plan is to consolidate existing resources in order to simplify management and reduce administration variables. You can consolidate services from multiple servers on fewer nodes in a cluster configuration, as illustrated in Figure 1-1. This allows you to provide services more efficiently and with greater reliability and availability. A good business continuity plan accommodates remote, mobile, and distributed systems with virtual centralized management, while providing comprehensive and automatic failover and redundancy.

Storage Requirement

Novell OES Solution

Data consolidation: The ability to consolidate files, data, and other network resources to leverage SAN and other high-availability solutions, while reducing the number of software and hardware configurations you need to manage.

For a general discussion of migration issues in OES, see Migrating Existing Servers and Data in the OES 11 SP2: Planning and Implementation Guide.

Cost effectiveness: The ability to make the best of the storage resources you have by adapting them to a variety of solutions in your network.

Because NSS supports a variety of storage architectures (as outlined in Section 2.0, Storage Architectures), you can easily use the resources you have whenever you modify your existing storage solution. For information, see the OES 11 SP2: NSS File System Administration Guide for Linux.
