[Gluster-devel] Re: [Gluster-users] I/O fair share to avoid I/O bottlenecks on small clsuters

[Mickey Mazarick]

Can you tell us a little more about your setup? I'm running many 
hundreds of vms on our cluster but I found infiniband is necessary if 
you have any large amount of io (databases, lots of drive access etc).

You may simply be saturating your io if you only have a single gigabit 
interface to your storage. Things like NFS mount can direct all your io 
down one gig link and can be the death knell to your distributed 
parallel filer.
