I have a HP Procurve 5406zl connected to two Windows 2012 R2 Servers (IBM 3650M4) with four 1 GBe ports each. One is a database server, the other is a Backup Server that should write data to a tape.
I'm trying to set up trunking with the Switch such that Maximum bandwidth (~4GB) can be used to send data from the db Server to the backup Server/tape. Unfortunatly no matter how I set up teaming and trunking, I do get only a Maximum bandwith of 1 GB for the Connection between both Servers.
I tried all kinds of combinations on the Windows side (Switch Independent teaming, Switch dependent teaming LACP and static) and on the Procurve side (LACP dynamic trunk, LACP static trunk and static trunk).
From what I read from the Microsoft documentation, the Windows side should be able to give me 4 GB/s for the outgoing Connections, however for the incoming Connection the Switch is responsible for the proper load balancing. I'm using a ProCurve 5406zl, sw Version K.15.10.0009, ROM K.15.30. I understand that there are newer Versions avalaible but does this help with my Problem ?
I tested I/O Performance with file copy operations and IOmeter Network tests between the two machines.
