Hello my name is Paul Kim.

 

I am trying to improve through spdk because of the nvme file write rate
limit on Linux.

Does not spdk support file systems that can be accessed and verified by end
users?

 

thank you.

SPDK does not currently support any POSIX-compliant filesystems. A filesystem would need to be ported to user space to run efficiently on top of SPDK, and some POSIX operations are either very tricky or potentially impossible to implement from a user space library (mmap comes to mind). We have implemented two libraries which are filesystem-like, but have very different semantics than a traditional filesystem. See lib/blob and lib/blobfs.

Thanks,
Ben
