[Disksim-users] add cache to SSD add-on

[陳信宏]

hi, all
fisrt , thx for ur sharing .
I have the same problem : IO queue saturation , but I didnt modify the
controller type (yet?) , is that necessary ?

All I do is  1. new  a  LRU-cache (replacement policy ) function
                  2. add it to the function  "ssd_media_access_request_element "

                  anything I forget to consider?

I modify the controller type into controller type=3 and config some related parameters , however, it did not work, some problems occur: Stopping simulation because of saturation, it seems that the IO queue length is larger than the Max queue length and the reason is that the replacement algorithm does not work...
