We have a Synology NAS RS810RP+ running DSM 2.3-1161 and there are several block level iSCSI devices configured. Each of the devices is used as iSCSI harddrive for a different ESXi VM.
(Every VM has one device and every device belongs to one VM, there is no sharing of devices between VMs)
We have assigned a seperate LUN to each iSCSI, so we have now:
VM0 <-> LUN 0 VM1 <-> LUN 1 ... VM9 <-> LUN 9
I guess every VM and every iSCSI device in our configuration needs a different LUN? But there are only 10 LUNs (0 to 9) possible in DS 2.3, this means we can only have 10 VMs living on the NAS?
We do not have all VMs running at the same time, so the resources are not an issue.
How can we host more than 10 VMs on the NAS?
