The dual controller configuration of the HPE MSA trumps the
Synology DiskStation's single controller configuration. For that alone, I would select the HPE MSA. Without that setup, any controller issue or firmware upgrade is disruptive to the systems the SAN is providing storage to. Furthermore, HPE's support is better than what Synology currently provides. The lack of phone support on Synology's part slows down the troubleshooting of issues compared to HPE. Furthermore, HPE's engineers are able to do a remote session and can work on the problems directly compared to Synology's support.
