Again we need time to have greater then 4TB replicated volumes, we will have it and if support replied with the same response it is because we need additional time. Right now our focus is on Auto Failover and other projects. Also there are many working with replication beyond 1TB. Having the option of using other DRBD Protocols is a good idea to select from but this will be determined by the engineers and management.

If you are having issues with your replication of volumes please send the logs to support@open-e.com
