Hello!
I'm facing a performance problem with my implementation of Tape library.
My environment:
- hyper-v Host that physically connects the HP tape library and provides iSCSI connection to my LAN
- hyper-v Guest (on the same host) that uses the tape library, running DPM 2016 UR6
The guest and the host are connected thru the virtual switch and the network bandwidth is 10 Gb
The problem is that when the guest sends the data to the tape, the network used is about 400mbps and the backups are very slow, so slow that it takes more than 24 hours to complete
I've applied some tricks on the network (jumbo frames end so on) but without luck. The DPM server is able to go faster that 4 Gb during the backup-to-disk so I don't think to have big network issues.
Is there something that I can check or modify to get my iSCSI connection go faster?
thank you!
