[Gluster-users] DHT and NUFA

I'm currently using Gluster with cluster/unify and nufa scheduler.
This has been working fine but I need lower latency and higher throughput,
so I'm thinking DHT. I have a couple of questions.

* for performance I want to read/write directly to the local volume.
As DHT has no central metadata this should not give problems as long as
the the data is on the right volume, correct?

* The data is already distributed (in the unify/nufa setup) with a
distributed hashing scheme. My initial idea was to hack my hashing scheme
into Gluster so they would agree on where the data should be, but then I 
spotted a file nufa.c in the DHT directory. Does this mean I can use
nufa with DHT? I can't find any documentation on this.

* Is there documentation about how DHT determines the location?

Thanks a lot for your help.
