This feature is scheduled for 2.1. We will try to have a pre-release available<br>
soon (in weeks). GlusterFS v2.2 will have a native NFS protocol translator.<br>

iSCSI exporting requires mmap support. You can create image files and losetup them<br>
as devices. Then it will be possible to export as iSCSI volumes. We just fixed<br>
a bug that caused poor mmap write performance. Work is on the way. We will keep<br>
you updated.<br>

Jonathan,<br>
You can export a Gluster mount via a client with a NFS server however the performance is pretty poor. As far as i know there is no way to export it with iSCSI.<br>
Your best option is to use a single/dual Linux/Solaris iscsi server to boot strap all your systems in xenServer and then use Gluster and fuse to mount your /data drive once the system is up and running.<br>

Hi all,<br>
<br>
I am attempting to prevent my company from having to buy a SAN to<br>
backend our virtualization platform(xenServer). Right now we have a<br>
light workload and 4 dell 2950's (6disks, 1 controller each) to<br>
leverage against the storage side. I like what I see in regard to<br>
the "Distributed Replicated Storage" where you essentially create a<br>
RAID 10 of bricks. This would work very well for me. The question<br>
is, how do I serve this storage paradigm to a front end that's<br>
expecting an NFS share or an iSCSI target? Does gluster enable me to<br>
access the entire cluster from a single IP? Or is it something I<br>
could run on a centos cluster (luci and ricci) and use the cluster<br>
suite to present the glustered file system in the form of an NFS share?<br>
<br>
Let me back up and state my needs/assumptions:<br>
<br>
* A storage cluster with the capacity equal to at least 1<br>
node(assuming all nodes are the same).<br>
<br>
* I need to be able to lose/take down any one brick in the cluster<br>
at any time without a loss of data.<br>
<br>
* I need more than the throughput of a single server, if not in<br>
overall speed, then in width.<br>
<br>
* I need to be able to add more bricks in and have the expectation<br>
of increased storage capacity and throughput.<br>
<br>
* I need to present the storage as a single entity as an NFS share<br>
or a iSCSI target.<br>
<br>
If there are any existing models out there please point me too them,<br>
I don't mind doing the work I just don't want to re-invent the<br>
wheel. Thanks in advance for your time and effort, I know what its<br>
like to have to answer newbie questions!<br>
