 Flash-aware Buffer Management Techniques
1. Research goal
  • Develop a buffer-aware flash management technique that eliminates unnecessary page migrations by taking into account both flash translation layer and buffer management layer
  • Design a new flash translation layer that considers the contents of a buffer cache
  • Design the buffer management scheme, so as to maximize the benefit of buffer-aware approach
