9、xibility this provides much more flexibility in how applications can be deployed on a Server cluster. Applications that support multiple instances can run more instances across more nodes; multiple applications can be deployed on a single Server cluster with much more flexibility and control over th
10、e semantics if/when a node fails or is taken down for maintenance.64-Bit SupportThe 64-bit versions of Windows Server 2003 Enterprise Edition and Datacenter Edition support Cluster Service. Large Memory Needs Microsoft SQL Server 2000 Enterprise Edition (64-bit) is one example of an application that
11、 can make use of the increased memory space of 64-bit Windows Server 2003 (up to 4TB Windows 2000 Datacenter only supports up to 64GB), while at the same time taking advantage of clustering. This provides an incredibly powerful platform for the most computer intensive applications, while ensuring hi
12、gh availability of those applications. GUID Partition Table (GPT) disks, a new disk architecture in Windows Server 2003 that supports up to 18 exabyte disks, is not supported with Server clusters. Terminal Server Application ModeTerminal Server can run in application mode on nodes in a Server cluste
13、r. NOTE: There is no failover of Terminal Server sessions. High Availability - Terminal Server directory service can be made highly available through failover.Majority Node Set (MNS) ClustersWindows Server 2003 has an optional quorum resource that does not require a disk on a shared bus for the quor
14、um device. This feature is designed to be built in to larger end-to-end solutions by OEMs, IHVs and other software vendors rather than be deployed by end-users specifically, although this is possible for experienced users. The scenarios targeted by this new feature include: Geographically dispersed
15、clusters. This mechanism provides a single, Microsoft-supplied quorum resource that is independent of any storage solution for a geographically dispersed or multi-site cluster. NOTE: There is a separate cluster Hardware Compatibility List (HCL) for geographic clusters. Low-cost or appliance-like hig

Windows Server 2003 provides no mechanism to mirror or replicate user data across the nod
17、es of an MNS cluster, so while it is possible to build clusters with no shared disks at all, it is an application specific issue to make the application data highly available and redundant across machines. Storage Abstraction frees up the storage subsystem to manage data replication between multiple
18、 sites in the most appropriate way, without having to worry about a shared quorum disk, and at the same time still supporting the idea of a single virtual cluster. No Shared Disks there are some scenarios that require tightly consistent cluster features, yet do not require shared disks. For example,
19、 a) clusters where the application keeps data consistent between nodes (e.g. database log shipping and file replication for relatively static data), and b) clusters that host applications that have no persistent data, but need to cooperate in a tightly coupled way to provide consistent volatile stat
20、e. Enhanced Redundancy if the shared quorum disk is corrupted in any way, the entire cluster goes offline. With Majority Node Sets, the corruption of quorum on one node does not bring the entire cluster offline.InstallationInstalled by DefaultClustering is installed by default. You only need to conf
21、igure a Cluster by launching Cluster Administrator or script the configuration with Cluster.exe. In addition, third-party quorum resources can be pre-installed and then selected during Server cluster configuration, rather than having additional resource specific procedures. All Server cluster config
22、urations can be deployed the same way. Easier Administration you no longer need to provide a media CD to install Server clusters. No reboot you no longer need to reboot after you install or uninstall Cluster Service.Pre-configuration AnalysisAnalyzes and verifies hardware and software configuration
23、and identifies potential problems. Provides a comprehensive and easy-to-read report on any potential configuration issues before the Server cluster is created. Compatability Ensures that any known incompatibilities are detected prior to configuration. For example, Service for Macintosh (SFM), Networ
24、k Load Balancing (NLB), dynamic disks, and DHCP issued addresses are not supported with Cluster Service. Default ValuesCreates a Server cluster that conforms to best practices using default values and heuristics. Many times for newly created Server clusters, the default values are the most appropria
25、te configuration. Easier Administration Server cluster creation asks fewer setup questions, data is collected and the code makes decisions about the configuration. The goal is to get a “default” Server cluster up and running that can then be customized using the Server cluster administration tools i
26、f required.Multi Node AdditionAllows multiple nodes to be added to a Server cluster in a single operation. Easier Administration makes it quicker and easier to create multi-node Server clusters.Extensible ArchitectureExtensible architecture allows applications and system components to take part in S
27、erver cluster configuration. For example, applications can be installed prior to a server being server clustered and the application can participate in (or even block) this node joining the Server cluster. Third-Party Support allows applications to setup Server cluster resources and/or change their
28、configuration as part of Server cluster installations rather than as a separate post-Server cluster installation task.Remote AdministrationAllows full remote creation and configuration of the Server cluster. New Server clusters can be created and nodes can be added to an existing Server cluster from a remote ma
