[Gluster-users] iSCSI?

I don't think this would be a great idea. Not just for the iSCSI targets but 
for ESXi datastore use. When a GlusterFS brick fails and resumes, replica 
reconstruction (given you use it), will eat almost the whole available 
bandwidth, making ESXi fail writing to virtual disks.
I had the same problem in my test environments.
