Cabling and deployment

To create a cluster from two RC18015xs+ appliances, we linked their Gigabit heartbeat ports using a standard Cat6 cable. Each link to the production network requires the corresponding ports on both controllers to be connected and we added a single RDX1215sas disk shelf to both of them using the supplied SAS cables.

Powering both units up automatically turns on any attached disk shelves and we then moved over to Synology's standard discovery web portal for further configuration. This found the cluster and installed the latest DSM software for us.

We loaded a quartet of 4TB WD SAS drives and created a single RAID5 array. We could add extra drives as hot spares or expand the array into them but this solution doesn't support SATA drives.
