Hi Viraj,<br>
<br>
Gluster Ver. 3.x supports replication over WAN but currently very
limited. I assume it will expand as time moves on.<br>
<br>
As for ISCSI. I doubt Glusterfs will ever support ISCSI. ISCSI
operates at the block level. Gluster only works on the filesystem
level. The only way to have iscsi on Gluster would be to export an
iscsi target that is a file on gluster. <br>
<br>
As for snapshot and deduplication in CIFS, I really don't know,
I'll pass that on to the other Gluster-users :)<br>
<br>
Hope this helped,<br>
<br>
Pat<br>

<div>Hi Pat,</div>
<div> </div>
<div>Actually we are looking for product that will do replicated
between server in WAN </div>
<div>but it should also support iscsi as we will be mounting it on
windows server, as we will be replicating data of windows volume</div>
<div>so i thought that if i could create a iscsi lun on linux
system(centos) and mount it on windows server as a volume and
then those iscsi lun can be replicated across the many server.
actually we are preparing for DR.</div>
<div>we will create the DR server in AWS EC2</div>
<div>we tried some products and they are quite expensive so we are
doing some research in open source.</div>
<div> </div>
<div>Also does glusterfs support snapshot and deduplication in
CIFS?</div>
<div>and when could glusterfs start supporting iSCSI any timeline
given.</div>
<div> </div>
<div>Thanks,</div>

experience with LVM is quite limited, but I think I
can help a bit. Glusterfs is a file system only.
It does not contain the block level hooks required
by LVM, so you will not be able to directly mount it
as a block level device. If you really want to use
glusterfs as the back end for the LVM you would need
to mount glusterfs into a directory and then use a
loopback file on the glusterfs mount point and then
use that loopback file for the LVM mount.</span></font></p>
