How to go over 1Gbps with 802.11ad?

[kenbrey]

I have a TS-869 Pro configured with both ethernet ports as trunking using IEEE 802.11ad mode. I am directly connected on both ports to an IBM 49Y4230 I340-T2 Intel Gigabit Ethernet Dual Port Server Adapter which is also configured to Team both ports with IEEE 802.11ad.

QNAP reports a connection speed of 1Gbps, while the adapter on the server reports being connected at a speed of 2Gbps. My maximum throughput measured by copying large files to an iSCSI partition on the QNAP is exactly 1Gbps, and Task Manager reports the network speed never exceeding 50%. A review of the QNAP Resource Monitor Bandwidth Usage shows that Ethernet 1 receives the vast majority of the packets, and Ethernet 2 receives almost nothing. Conversely, Ethernet 2 does all the sending and Ethernet 1 sends nothing.

Can I expect to get more than 1Gbps between my QNAP and a single server? Would I be better connecting through a switch that also supports IEEE 802.11ad than I am connecting directly?

QNAP reports a connection speed of 1Gbps, while the adapter on the server reports being connected at a speed of 2Gbps.

The GbE links are still two at 1 GbE each. I know some teaming software does sum the information presetned to the UI for the "virtual" adapter - the NAS does not add the trunk member bandwidth in the Web UI. Something they should consider, taking the fact newer NAS firmware does allow to team moe than just two interfaces (haredwae permitting of course).

Can't predict you what cna be expected in a non-switch setup.

Consider to configure a plain standard static trunk on both sides, not rquiring any negotiation.

A subsequent test with the same system but this time connected through 4 ports on a D-Link Smart Switch with IEEE 802.11ad enabled yields no differences.

schumaku,
What do you mean by "plain standard static trunk"? QNAP supports many trunk modes. From the descriptions it sounds like Balance-alb may be the way to go with a direct connection. But how do I configure my server's NIC? Just as 2 independent network ports with their own addresses on the same subnet?

[kenbrey]

My IBM NIC provides several options for trunking modes:
Adaptive Fault Tolerance
Adaptive Load Balancing
Static Link Aggregation
IEEE 802.3ad
Switch Fault Tolerance

The QNAP has these modes:
Balance-rr
Active Backup
Balance Xor
Broadcast
IEEE 802.3ad
Balance-tlb (Adaptive Transmit Load Balancing)
Balance-alb (Adaptive Load Balancing)

So far, I have tried 3 combinations:
IEEE 802.3ad -> IEEE 802.3ad
Adaptive Load Balancing -> Balance-alb (Adaptive Load Balancing)
Static Link Aggregation -> Balance-rr

Of these 3, I have the best performance copying data to the QNAP using IEEE 802.3ad. However, it still never goes over 1Gbps, so doesn't exceed the performance of just a single basic. I tried all 3 direct, or with a smart switch inbetween. The addition of the switch hasn't helped.

Are there any other combinations that seem worthwhile to try?

Static Link Aggregation -> Balance-rr

This is the one that I had the best hopes for. I'm surprised to hear about disappointing results with it

I'm sorry that I haven't got the equipment available to be able to contribute, but I find this a very interesting thread.

Hope you considered some other -- non important stuff, like CPU, raid calculation, hdd speed...
BTW I've 802.11ad as well, and I've noticed that different services uses different ethernet ports... like rsync on port1(only), ftp on port2 etc.
