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

• A、Provides a highly available cluster of Power Systems enabling near linear scalability and disaster recovery across different sites.
• B、Incorporates a hardware locking mechanism which resembles the Parallel Sysplex on the mainframe， delivering performance and scalability.
• C、Enables near linear scalability by partitioning and clustering the database across multiple nodes， and adding nodes dynamically when needed.
• D、Provides scalability by employing a highly available cluster of servers interconnected by an Infiniband network and a central locking mechanism.
