DSS6 Beta Automatic failover with remote replication

[urvik]

Hello All,

I have three DSS server. Two are at local site and one at remote site. I will use automatic failover on local site between 2 DSS server. Automatic failover is working fine. I want to do remote replication of my local DSS servers(which are doing local auto failover) to remote site DSS server for disaster recovery(like fire, earthquake etc.)

Can I do that with DSS6? If yes can someone guide me?

Thanks,
Urvik

You can with NAS shares using the Data Replication feature but not with iSCSI Replication.

For more details on this please see the link below and look at the Data Replication over a WAN.

Hi there,

I'm really disappointed about this. Especially companies that want to use your product to create a fault tolerant / stable / professional environment and therefore choose to implement an iSCSi failover cluster also want to use WAN file replication to replicate those volumes also to another datacenter/location so they also have made sure the data is available for disaster recovery. As it is not supported by Open-E we need to use 3th party backup programs with all the complex configuration to achieve that information on the volumes is replicated.

So I think it would be nice to see Open-E finding a solution for this.

The real issue is that you can't do a file-level backup with iscsi volumes on the target side because the target-side is supposed to be filesystem agnostic. Now, any client systems that have the iscsi volumes mounted can perform a file-level backup. So, we have a red hat system rsync the files on the iscsi volumes over to an Open-E NAS, and from there we use the built-in "data replication" feature to replicate to another open-e nas at an off-site location. We could actually just rsync the files directly from the red hat system to our off-site NAS, since the "data replication" is just a webgui-ified rsync implementation.


Also, when is NAS autofailover coming out?

As you know this far more difficult then iSCSI but we do have this on our road map Q4 - latest Q1 of 2010.
