Open-E DSS Replication

[Robotbeat]

We have a set up at one of our customers with 2 open-e iSCSI boxes (one replicating to the other) that are then mounted on a red hat server. The mounted volumes are then rsynced (i.e. file/data replication) to another box (a NAS open-e box), which is then rsynced to an off-site box over the internet. So, you could do it that way.

So in you example abox the Red Hat host server rsynced the attched iSCSI volumes to a Open-E NAS box, is that correct?

[Robotbeat]

That is correct. Also, the main iscsi open-e box was also (block-level) replicated to another open-e iscsi box through a point-to-point connection between the two iscsi boxes. (In other words, this block-level replication was accomplished without the intervention of the red-hat server.)

Right, that looks like what we may end up doing at this time. Thanks for the information.

Hey Tom,

I came up with one new question. Does replication only work between 2 Open-E boxes or can I mount any iSCSI target in Open-E and replicate to that LUN?

Sorry Todd, I wrote Tom by mistake.

No worries on the name . With Volume Replication (Block level) combinations are DSS to DSS or DSS to iSCSI R-3 Enterprise. With Data Replication (rsync) DSS to DSS, DSS to NAS R-3 Enterprise and or any other Linux system.

rsync command used to synchronize from your operating system to Open-E
server can look similar to this:

cd $SOURCE_DIR
export RSYNC_PASSWORD=${PASSWORD}
rsync -raRx --acls --xattrs --whole-file --delete --force "./"
"$LOGIN@$RSYNC_DEST_IP::$DEST_SHARE"

rsync command used to synchronize from Open-E server to your operating
system (executed on your operating system) can look similar to this:

cd $DEST_DIR
export RSYNC_PASSWORD=${PASSWORD}
rsync -raRx --acls --xattrs --whole-file --delete --force
"$LOGIN@$RSYNC_DEST_IP::$SOURCE_SHARE" "./"
