Server Clustering and Failover Hardware Requirements
This topic describes the hardware required for your product installation.
The hardware requirements set by Microsoft for clustered server configurations must be met for systems deploying Workflow with cluster support.
- Failover clustering is supported on Workflow 1.5 SP4 and greater.
- SQL Server must be installed in a central location on the domain.
Important:
- All computers in a failover cluster must be on a domain.
- Failover clustering is not supported on Workflow legacy servers.
- Workflow server clustering provides support against hardware failures only.
Custom services managed by clustering must maintain their state in shared persistent memory (typically a database), and the state must always be in a consistent state because failover can occur at any time.
