Explanation

A: Smart Flash Cache caches hot data ?Not just simple LRU Knows when to avoid caching to avoid flushing cache ?Allows optimization by application table B: The inter-database I/O allocations are defined within the software in the Exadata cell and managed by the I/O Resource Manager (IORM). The Exadata cell software ensures that inter-database I/O resources are managed and properly allocated within, and between, databases. Overall, DBRM ensures each database receives its specified amount of I/O resources and user defined SLAs are met. In essence, Exadata I/O Resource Manager has solved one of the challenges traditional storage technology does not address: creating a shared grid storage environment with the ability to balance and prioritize the work of multiple databases and users sharing the storage subsystem. Exadata I/O resource management ensures user defined SLAs are met for multiple databases sharing Exadata storage. This ensures that each database or user gets the correct share of disk bandwidth to meet business objectives.
