Prerequisites
Hardware and Software Requirements:
- Servers (Nodes): minimum of two servers with identical or compatible hardware and running the same version and edition of Windows Server. All nodes must be either 32-bit or 64-bit platforms, matching the SQL Server edition.
- Operating System: supported Windows Server version (e.g., Windows Server 2022) with the Failover Clustering feature installed on all nodes.
- SQL Server: SQL Server Standard or Enterprise edition, compatible with the Windows Server version.
- Shared Storage: all nodes must have access to shared storage (e.g., a Storage Area Network - SAN) for SQL Server data and log files.
Network and Domain Configuration:
- Network: Each node requires network connectivity, with a dedicated network recommended for internal cluster communication.
- Domain: All cluster nodes must belong to the same Active Directory domain.
- IP Addresses: Multiple IP addresses can be specified for each FCI, with dependencies configured as AND for addresses on the same subnet and OR for addresses across multiple subnets.
Pre-installation Configuration:
- Windows Server Failover Clustering (WSFC):The WSFC feature must be installed and configured on all intended cluster nodes, including the creation of a cluster group for each FCI.
- Hardware Validation:All hardware components must be certified for the installed Windows Server version and pass the cluster validation tests.
- Service Accounts:Dedicated domain accounts should be prepared for SQL Server services (e.g., Database Engine, Agent).
- Security:Review and implement necessary security considerations for the SQL Server installation.
Installation Steps (High-Level):
- Prepare the hardware and install Windows Server on all nodes.
- Install the Failover Clustering feature on all nodes and configure the Windows Server Failover Cluster.
- Install SQL Server on the first node, selecting the "New SQL Server failover cluster installation" option.
- Add the remaining nodes to the existing failover cluster using the SQL Server setup.
- Configure SQL Server services, data directories, and other settings within the cluster.
