Mount a filesystem on a PCIe SSD over PCI direct?

[Alastair_M_]

Dear all,

I am wondering if it is possible to directly mount a filesystem on a PCIe SSD over PCIe directly?

If not, what are the alternatives?  Is NFS via the host processor the only other solution?

Best regards,

Alastair

Hi Alastair,

I'm not a PCIe expert but I'm sure that one of our colleagues out there will correct me where I'm wrong.

My short answer is that I believe the answer no, at least not in the way that you want.

I believe you want to access the SSD and mount a file system resident on it from the coprocessor with no heavy lifting. I don't think this is possible.

That said, I also suspect that it is theoretically possible though would require substantial modification to drivers and the PCIe hardware that supports the SSD's PCIe interface.

Regards
