Smart Flash Cache
If your database is running on Solaris or Oracle Linux, you can optionally add another memory component: Database Smart Flash Cache (the flash cache). The flash cache is an extension of the SGA-resident buffer cache, providing a level 2 cache for database blocks. It can improve response time and overall throughput, especially for read-intensive online transaction processing (OLTP) workloads. The flash cache resides on one or more flash disk devices, which are solid state storage devices that use flash memory.
