You would need 4 bricks of 100GB, 2 on each server, and create a
distribute-replicate volume, with replica count of 2.
The command to be run would be of the syntax given below.
gluster volume create <VOL-NAME> replica 2 server1:/bricks/brick1
server2:/bricks/brick1 server1:/bricks/brick2 server1:/bricks/brick2
The order in which the bricks are given in the command is important to
specify which bricks form replica sets.
Since the replica count given in the above example is 2,
server1:/bricks/brick1 - server2:/bricks/brick1 will be a replica set,
and server1:/bricks/brick2 - server1:/bricks/brick2 will the other
replica set.

Thank you for your help!
I would like to confirm the command you gave. Should:
gluster volume create <VOL-NAME> replica 2 server1:/bricks/brick1
server2:/bricks/brick1 server1:/bricks/brick2 server1:/bricks/brick2
Be:
gluster volume create <VOL-NAME> replica 2 server1:/bricks/brick1
server2:/bricks/brick1 server1:/bricks/brick2 server2:/bricks/brick2
