大家有没有用过DataCore UpTempo ？
类似SuperCache II，也是Block level cache。


What is Uptempo?

- Advanced disk block cache, a sophisticated "virtual" I/O controller that sits below the file system

- An I/O scheduler

- A combination of very advanced mechanisms for increasing the performance of local I/O

- A set of predictive self learning and workload aware algorithms

- A general schema for reducing exception overhead for disk I/O

- Software that sits 'below' the Windows file system and improves its performance

- Simple-to-use and automated software, requiring no application knowledge from the user
