How to count the P/E cycles of an virtual OCSSD? #68

Hello, I'm surprised the so few issues. LigntNVM is a great tool. Recently, I'd like to build an open-channel SSD environment to simulate my FTL. And I want to know if Virtual OCSSD can support P/E tracking or evaluating performance？

Hi,

The qemu here isn't build to evaluate performance. However, you can check out Huaicheng's FEMU - which simulations OCSSDs and also allows performance evaluations.

It is available here: https://ucare-uchicago.github.io/femu/ There is also a paper available that describes it: https://www.usenix.org/system/files/conference/fast18/fast18-li.pdf
