@tony - What is a SAN? a Very very big question, a whole books worth of explanation to answer! Storage Area Networks have so many facets today each of which is a topic in itself.

Very (Very) simply from a DBA's point of view think of it like this - as much storage as you need, at the speed you need, with the reliability/recovery that you need. This all pre-supposes that your Organisation can afford it and your IT department allow it!

SAN storage is the storage located on storage area network. As DBA you need to make sure the LUNs allocated to you meets your requirement i.e. are correct disk and raid types. Most of the DBAs I worked with prefer LUNS on 15000 RPM fiber channel disks with RAID 10, that is the max performance most of SANs can provide the newer SANs also includes SSD drives which gives much better performance.

Hi Tony, the above comment has good content, if you're willing to subscribe to the site and to overlook the SQL Server references :)  Just in case you're looking for something more basic, consider that any computer begins with some storage media.  Hard drives, virtual, cloud, whichever -- but conceptually physical.  On a PC, a hard drive is next partitioned and formatted.  Layered onto that medium are an operating system, and more logical partitioning as file storage.

A SAN, simply, is a logically defined set of file storage, that is able to behave as a unified whole.
