IF JBOD, && Linux, THEN yes you can know, through SMARTTOOLS, or something like that…

However, I can’t imagine how you’d get 2 separate PCIe

( presuming NVMe devices …

… no, this thing must be presuming SATA, NOT NVMe …

even in SATA, there’s no bifurcator for SATA, I don’t think:

SAS has expanders, which can take a single SAS channel & attach something like 128 SAS devices onto it,

PCIe has some kind of equivalent, and there is a PCIe card which crams loads of NVMe’s into it, out in the last year, but SATA??

Hmm… )
