Two topologies:
- Single server
- Farm = web front-end + web front-end + SQL server
Small farms
- Components scaled to two tiers
- Dedicated SQL server stores content
- Web front-end (WFE) hosts web pages
Medium farm
- Three tiers
- Clustered or mirrored SQL server at back-end
- Extranets
Large farm:
- Network load-balanced WFE servers
- SQL clusters for database storage
- Ideal where database availability is critical
- You can configure additional servers after deployment.
Three tiers:
- WFE
- Search server (search results restricted to sites and subsites)
- SQL servers - WSS 3.0 databases - one or more clustered servers: configuration database; central administration database; content database; search database.
Scalability Options
- Scale out
Single server to small farm >> adding WFE
Small to medium farm >> add search server
Medium to large farm >> add WFE servers or other options
- Scale up
Small >> add WFEs or clustered SQL servers
Medium >> add WFEs or search server
Large >> more . . . RAID or number of servers
Scale out to small farm when or department gets more people.
