Replication - many to one is not possible now only 1 to 1. We are working to developed this sometime next year (no set date as of yet).
Replication "Volume Replication" is synchronous, we use DRBD (you can research this on the net for more details). Info below on our current replication now. Information with AutoFailver will be released at a later date - when announced.
iSCSI Target Volume Replication replication is very similar to RAID 1. The first stage is rebuilding of the destination to be the copy of the source volume. Next stage (endless) is online modifying the destination volume to keep the mirror. The difference comparing to the RAID 1 is that, after any broken connection only the changed data will be 'rebuild' (again first stage takes place) on the destination.
Note: the replication should be performed on separate NIC and the connection should be as fast as the main network connection, to prevent lowering data throughput. Once you create the Target Volume you have the choice to set it as Source or Destination to the mirrored server. Replication of volumes should be same size.
Failover replication will be available once announced on our website. We have finial bata versions now - so should be within the end of next week - providing no other issues arise.
Jumbo frames is located in the console screen for "Hardware Configuration menu" (ALT+CTRL+W) choosing Tuning options.
List of good hardware - well most use what RAID controller interfaces with our GUI - so
3ware or areca controllers can be used. All the ones we support are on the link below.
Just make sure to use a BBU w/WB function on the RAID controller.
