Hi all: I am gonna run a cluster active/passive with 2 nodes and 2 processors each. Do I need two SQL Server 2000 Enterprise 1 Processor License - Unlimited Clients ? Kind regards, Pablo.
Q. How does licensing work for computers that run SQL Server 2000 Enterprise Edition in failover scenarios? A. Failover support, where servers are clustered together and set to pick up each others' processing duties if one computer should fail, is available only in SQL Server 2000 Enterprise Edition, just as it was with SQL Server 7.0. Failover support can be configured in one of two ways: a.. Active/active. In the active/active configuration, all servers in the cluster regularly process information, but one or more take on the workload of a failed server. b.. Active/passive. In the active/passive configuration, one or more computers in the cluster do not regularly process information but rather passively wait to pick up the workload when an active server fails. All active servers in a cluster must be fully licensed, according to either the Per Processor licensing model or the Server/CAL licensing model. However, if a server is strictly passive, working only while an active server has failed, no additional licenses are needed for that passive server. The only exception to this rule is if the cluster is licensed using Processor licenses and the number of processors on the passive server exceeds the number of processors on the active server. In these cases, additional Processor licenses must be purchased for the additional processors on the passive server.
