[dm-devel] DMCache Desing Questions

[Leonardo Santos]

Hello,

Could anyone explain me about DMCache structure answering some questions?

1. How is metadata structure organized? B+ Tree from DM, so is it like
BCache?
2. What is the I/O path (i.e. when does lookup, policies and operation
modes act and in what order) ?
3. Is MQ completely based in paper from Yuanyuan Zhou et. al. "Second-Level
Buffer Cache Management" (except pre_cache (fifo) changed to MQ in DMCache)
or there is another change?
4. Is DMCache inspired by another DMCache implementation like "DMCache"
from Ming Zhao?

Thanks!
Leonardo Santos
