The article seemed to lack software requirements for a MSSQL cluster. We operate different versions of MSSQL, from what I've read only SQL Enterprise supports clustering. With that said, there's a high cost involved with the software itself. Anyone with ideas on clustering with a lower end version of MSSQL like Standard, or Web? We're considering "log shipping" and backing up to a central location so we can restore from a second active or standby SQL server.
