Multiple SQL servers sharing Common Disk

Is it possible to have 2 SQL 2000 (STD) servers access a common RAID
disk containing the database and work concurrently?
No.

|||Clustering is a high availability solution, not a scale-up solution.
Mirroring allows read-only access to the target database.
SQL does not scale out, it scales up.

|||You are looking for failover clustering. You use a highly-redundant disk
array such as a SAN, two or more host computers, and Windows and SQL
Software to build a failover cluster. The systems are physically
interconnected at all times, but the cluster software arbitrates ownership
so only one host computer owns a SQL server instance, and its associated
resources) at any one time.
Here is a good overview on SQL failover clustering
