    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.
