Which SSD can use cmb_ copy test P2P?
xiaowen.huang at hotmail.com
As far as I know, Intel DC P4600 pcie3.0 x4 can support CMB function, but when looking for this model in online stores, it is divided into normal version and customized version, and there is no data manual to indicate whether CMB is supported. I saw a model SSDPEDKE040T7L1 on the online stores. The merchant said it was a customized version made by Intel for Lenovo. I don't know whether this model supports CMB.

We usually use QEMU emulated NVMe SSD for the CMB tests, if you just want to evaluate this feature you may use the emulated NVMe SSD.

we are developing Switch, and we want to verify P2P funtion through two SSD. so, I don't understand how QEMU emulated in this situation.
