[Gluster-users] how do you know which client picks which storage hosts to write to?

I am running glusterfs3.4.2-1 and I would like to understand deeper about 
how the fuse-client decides who is the first to response, and what tuning 
can be done to disconnect the fuser-client to the storage that is taking 
the longest to respond? 

I have an 8 node distri-rep. setup of 300G in a 2x4 setup.

gluster volume info prodstatic

Volume Name: prodstatic
Type: Distributed-Replicate
Volume ID: 187c241d-0eeb-4405-80f2-c704ea44bc36
Status: Started
Number of Bricks: 2 x 4 = 8
Transport-type: tcp
Brick1: omhq1140:/export/content/static
Brick2: omdx1c5d:/export/content/static
Brick3: omhq11ad:/export/content/static
Brick4: omdx1781:/export/content/static
Brick5: omhq1c56:/export/content/static
Brick6: omdx1c58:/export/content/static
Brick7: omhq1c57:/export/content/static
Brick8: omdx1c59:/export/content/static
Options Reconfigured:
server.statedump-path: /debug
features.quota: on
server.allow-insecure: on
network.ping-timeout: 10

will the fuse-client "prefer" any a node that or set of nodes to get its 
files over another?
