OP ratio
Opened this issue · 4 comments
Just to confirm, I'm wondering does it mean (T - U) / T or (T-U) / U in MQSim?
Thank you for your time and help!
Hi @ZiyangJiao,
Can you please clarify which parameter are you referring to?
Thank you for your reply. It's Overprovisioning_Ratio: the ratio of reserved storage space with respect to the available flash storage capacity. Range = {all positive double precision values}.
Plus, I'd like use MQSim to validate the write amplification caused by garbage collection. But it seems that MQSim doesn't support 100% preconditioning(setting initial occupancy = 100% and working set = 100%) .
Hi @ZiyangJiao,
As you can find the usage of the parameter in classes like Logical_Address_Partitioning_Unit.cpp, it is (T-U)/T. In other words, it is the ratio of the reserved space to the total available storage space.
