Analysis Services supports quite a number of options to assist in meeting processing or querying goals. Key to the architecture of Analysis Services is that it natively supports server failover clustering.
Processing can be done on one instance of Analysis Services, and the processed data may then be copied to other instances used for querying. Many different ways to copy the data exist including but not limited to SAN Snapshots, Storage Mirrors, XCopy, and Analysis Services Cube Synchronization.
Querying can be managed through the use of several identical Analysis Services instances that are clustered and placed behind a Network Load Balancing (NLB). More details are available in the SQLCAT article Analysis Services Load Balancing Solution located at http://sqlcat.com/sqlcat/b/technicalnotes/archive/2010/02/08/aslb-setup.aspx.
