PowerHA pureScale and DB2 pureScale on Power Systems
DB2 pureScale reduces the risk and cost of business growth by providing unlimited capacity, continuous availability, and application transparency. It is designed to meet the most demanding transaction processing needs, both now and in the future. Breakthrough levels of availability are ensured thanks to uninterrupted processing during node failures and a redundant architecture. Adding capacity is painless because DB2 pureScale does not require application changes or database tuning.
DB2 pureScale on IBM Power Systems incorporates PowerHA pureScale technology to deliver levels of database scalability and availability unmatched on UNIX or x86 systems. This technology provides the following value:
Centralized coordination which reduces system overhead
Centralized database locking and caching minimizes the processing overhead of inter-node communications.
Direct memory access for high efficiency data transfer
Data transfer is performed by Remote Direct Memory Access to virtually eliminate processor context switching.
Resilient design which enhances business continuity
Data and lock status are immediately accessible to all nodes, ensuring consistent application performance even if a node fails.
