I have been playing around with the volume replication feature and impacts the performance significantly.
Now, I have swapped out a fairly old server and swapped in a quite new one, to make sure that have hte fasted speeds possible to and from my RAID systems. Both Open-E boxes achieve 110 MB/sec to and from the RAIDs.
Then I started the replciation job and after the initial replication had been finished, both RAIDs still show quite a huge amount of "traffic". The source volume shows consistent reads of 40 MB/sec. constantly, even when no iSCSI initiator is connected to that volume.
The destination volume in turn shows a consistent transfer of 25 MB/sec all the time.
Is volume replicaiton really meant to work this way? I though that the Open-E box would only transfer the blocks that have been changed.
right now, I am using the demo cd to evaluate Open-E. I have searched the forums a bit and it seems that there is to a new demo cd scheduled to be released next monday.
Maybe, I will get better results with the new version, as it seems that the current demo cd is quite outdated.
But what I gather from your question is, that this is not the way its meant to be, so that's at least good news.
