Hallo,
ist die dritte Netzwerkkarte vielleicht nicht SMB 3.0-„fähig”?
1.2. Requirements
SMB Multichannel requires the following:
- At least two computers running Windows Server 2012 or Windows 8.
At least one of the configurations below:
- Multiple network adapters
- One or more network adapters that support RSS (Receive Side Scaling)
- One of more network adapters configured with NIC Teaming
- One or more network adapters that support RDMA (Remote Direct Memory Access)
3.2. Multiple NICs
When using multiple NICs without SMB multichannel, if there is only one SMB session established, SMB creates a single TCP/IP connection using only one of the many NICs available. In this case, not only it’s not possible to aggregate the bandwidth of the multiple NICs (achieve 2Gbps when using two 1GbE NICs, for instance), but there is a potential for failure if the specific NIC chosen is somehow disconnected or disabled.
With Multichannel, SMB will create multiple TCP/IP connections for that single session (at least one per interface or more if they are RSS-capable). This allows SMB to use the combined NIC bandwidth available and makes it possible for the SMB client to continue to work uninterrupted if a NIC fails.
