I have vpshere 4.1 with one dl 380 g6, with 2 146 gig disks in raid1 and 3 146 disks in raid 5. all running smootly on a cisco catalyst 2960 switch.All are gigabit.
I also have a qnap 459 pro plus and netgear ready nas ultra 6, with jumo frames enabled (also tried to disable).
When I want to make a backup via vmprotect (acronis) and I select all the vms (4 of 40 gig). I see a throughput of max 4 mb per second. I cannot get a higher backup (30 mb ??)
I tried to make the qnap/netgear an iscsi device and backed up to the local drive and also backed up via networkshare; no difference.
Any ideas ?
