BufferPool
Pages of data stored in memory. Governed by 'max server memory' setting.
VAS

Two names for the same thing. Describes bon-buffer-pool memory, i.e. amount is not governed by 'max server memory' setting. Think of this as memory SQL Server needs to support things like CLR objects and Linked Server requests.
