In a scale-out environment，what is a benefit of running DB2 pureScale compared to other solutions？（）

Provides a highly available cluster of Power Systems enabling near linear scalability and disaster recovery across different sites.

Incorporates a hardware locking mechanism which resembles the Parallel Sysplex on the mainframe， delivering performance and scalability.

Enables near linear scalability by partitioning and clustering the database across multiple nodes， and adding nodes dynamically when needed.

Provides scalability by employing a highly available cluster of servers interconnected by an Infiniband network and a central locking mechanism.
