Not good enough <| sep |> I ' ll use this as pasta <| sep |> I have a pair of DS 916 and had the same issues . I believe the reason is a lack of MPIO stuff in Synology . Those run in activepassive mode . For the failover , I see it is long as hell taking more than 60 seconds . LACP , teaming or VLAN is not good for iSCSI either . I decided to use a VSAN on top of these boxes for mirroring and failover , so just use them as iSCSI connected disks . I have installed StarWind as improved iSCSI target on host side with RAM and SSD caching to make things much faster . StarWind does MPIO and all the things utilizing up to 2 GbE on both Synology boxes . Very happy so far . virtualsan <| sep |> He ' s done it again ! <| sep |> lol my bad . had to get you guys in here somehow
