Server, which allows not only clustering and load balancing, but also more flexibility to do it with by allowing four clustered nodes, instead of the limit of two with Advanced Server Important design tips to remember are the following: when clustering and load balancing with Windows 2000, Windows 2000 Server won’t support clustering and load balancing unless Application Center 2000 is installed; Windows. .. Windows 2000 clustered solution the groundwork for the other chapters because, as you get into the actual configuration and testing of, say, SQL 2000, you could find that failover and failback might not always work This is important to anyone who wants to run a SQL Server cluster Figure 1- 7 Configuring failover clustering 11 12 Windows Server 2003 Clustering & Load Balancing Stateless vs Stateful Clustering. .. 1- 10 Figure 1- 8 Stateless vs stateful clustering Chapter 1: Figure 1- 9 Introduction to High Availability, Clustering, and Load- Balancing Technologies An example of Active/Passive clustering Active/Active Active/Active clustering is when you want all servers in the cluster group to service clients and still be able to take up the load of a failed server in case of disaster, as seen in Figure 1- 10 That said,... 2000 Advanced Server will support a two node cluster and load balancing; and Windows 2000 Datacenter Server will support a four-node cluster and load balancing To understand Microsoft’s position on this service, you should know Microsoft offers four types of clustering services With Windows 2000, you have the Microsoft Cluster Server (MSCS), network load balancing (NLB), component load balancing (CLB), . . . . . . 10 Network Load Balancing . . . . . . . . . . . . . . . . . . . . 14 Server 2003 Clustering and Load Balancing . . . . . . . . . . . . . 17 Windows Server 2003 Enterprise Servers Companies, Inc.
