I have two Synology boxes (DiskStation DS1817+) that are running in Synology HA mode filled with WD Black 4TB drives in RAID10. They are connected to my cluster over iSCSI providing mainly backup storage, file share (in a separate File Server VM) and hosting a couple of DEV virtual machines and test labs.
The problem is that these boxes run in an Active-Passive mode which is not completely great since I get the performance of a single box only (which is already not sufficient on current stage) and failover takes too much time (around 2 minutes) which cause the services running there to die. Is there any way to switch them to active-active so both boxes are used to speed things up?
Another way I am considering is converting them to RAID0 but it’s obviously a bit scary. Furthermore, I am not sure that 4x1GbE networks will not bottleneck the RAID0 performance in this case. Any suggestions are highly appreciated.
