Implementation Tips
Windows 2000 Clustering
Shared disk approach
Windows 2000 Advanced Server
– Two nodes
– Four nodes possible with Data Center
Install using Cluster Service
Manage using Cluster Administrator
– Resources
– Groups
“Standard” Win2K Cluster

SQL Server 2000 Clustering
SQL Server 2000 Enterprise Edition
Install using SQL Server Setup
– Create virtual server
– Single instance or multi-instance (not
active-passive or active-active)
Manage using Enterprise Manager

Implementation Tips
Plan, plan, plan!
Plan shared disk space
– Nothing should go on the Quorum drive
– Recommend RAID-1 for Quorum
– Recommend RAID-10 (or at least
RAID-5) for SQL database files
– Recommend RAID-1 for SQL log files
– Need at least 2+2+3=7 drives!
Don’t skimp on hardware
Implementation Tips
Plan, plan, plan!
Plan network setup
– Public network IP addresses for cluster
nodes, the cluster itself, and each SQL
Virtual Server
– Private network for cluster nodes
– WINS and DNS services running
Create service accounts beforehand
Don’t forget MSDTC setup
Implementation Tips
Test, test, test!
Cluster failover
Hardware failures
– Network cards and cables
– Shared disk arrays and cables
– Entire node shutdowns
SQL Server and application failures
