Is there any reason not to store data on a SAN using SQL Server 2008? This is for an OLAP database. thank you.

SAN is good from the point of view of manageability and disaster recovery and should be a perfectly good storage solution for any database. However, it's easy to cripple databases with a poorly configured SAN, especially in mixed environments where storage is shared with and optimised for other types of workload. Take advice from your SAN vendor or specialist about the best way to configure your hardware for SQL Server. Microsoft also have some recommendations. See:

Very useful for disaster recovery - using san mirroring . There are also some other side benefits , such as Fastcopy - to move large files around quickly.

Well jackv,

Are you using SAN Mirroring? Does it support geographical sites or limited sites?

Using synchronous mirroring across different sites at the drive level. Two variations : 1) on some servers we're mirroring drives with similar sql server configuarion on either side - i.e c:\ is local everything else is SAN 2) All drives mirrored ,and the server boots off SAN. These solutions aren't HA , but are DR based
