TS-509 pro link aggregation problem (STILL not fixed!!!)

Discussion on setting up QNAP NAS products.

Re: The TS-509 pro does NOT really do link aggregation

Postby jello_moto » Fri May 22, 2009 11:40 pm

For those not understanding Alfreds explanation, I have two teamed NIC's talking to an iSCSI disk on the QNAP. Since the QNAP see's the teamed NIC's as the same MAC address it only uses one port for traffic due to the type of aggregation they are using. If another MAC address connects to the QNAP it would open up the second port for traffic. (I haven't tested this).

Hopefully if this is fixed in the next firmware release I'll have a nice blazing 2 gigabit (ish) iSCSI disk!!! :)

Dear rudku:

You were useing web file manager to transmit a big file via NFS?
I don't really understand your test topology, could I get more detail about it.

Dear jello_moto:

In the following version if you want to use load balance ,we will provide seven modes for you as below:


Balance-rr (Round-Robin) Transmit packets in sequential order from the first available slave through the last. This mode provides load balancing and fault tolerance. This mode provides load balancing and fault tolerance.

Active Backup Only one slave in the bond is active. A different slave becomes active if, and only if, the active slave fails. The bond’s MAC address is externally visible on only one port (network adapter) to avoid confusing the switch. This mode provides fault tolerance.

Balance XOR Transmit based on the selected transmit hash policy. The default policy is a simple [(source MAC address XOR’d with destination MAC address) modulo slave count]. Alternate transmit policies maybe selected via the xmit_hash_policy option. This mode provides load balancing and fault tolerance.

Broadcast Transmits everything on all slave interfaces. This mode provides fault tolerance. This mode provides fault tolerance.

IEEE 802.3ad Creates aggregation groups that share the same speed and duplex settings. Utilizes all slaves in the active aggregator according to the 802.3ad specification. This mode provides load balancing and fault tolerance but requires a switch that supports IEEE 802.3ad Dynamic Link Aggregation with correct LACP mode configured.

Balance-tlb (Adaptive Transmit Load Balancing) Channel bonding that does not require any special switch support. The outgoing traffic is distributed according to the current load (computed relative to the speed) on each slave. Incoming traffic is received by the current slave. If the receiving slave fails, another slave takes over the MAC address of the failed receiving slave. This mode provides load balancing and fault tolerance.

Balance-alb (Adaptive Load Balancing) Include balance-tlb plus receive load balancing (rlb) for IPV4 traffic, and does not require any special switch support. The receive load balancing is achieved by ARP negotiation. The receive load balancing is achieved by ARP Replies sent by the local system on their way out and overwrites the source hardware address with the unique hardware address of one of the slaves in the bond such that different peers use different hardware address for the server. This mode provides load balancing and fault tolerance

Thanks Alfred. I am looking to get as close as possible to the two gigabit maximum theoretical speed of the interface.

My tests are based on real file transfer speeds betwen two high end NAS form QNAP.
I tested, what effect has a LACP during real file transfer of big file (movie with 33,5 GB size).
I tested file transfer only between QNAP NAS models TS-509 or TS 809U-RP
File transfer protocols: nfs and ftp (copy only via web file manager or download manager diretly on NAS)
Gigabit switches on which I tested (all with IEEE 802.3ad support, I verified the LACP configuration on both sides switch-NAS)
- Netgear GS108T
- HP ProCurve 1800-24G
- HP ProCurve 1800-8G

Here are latest results:

QNAP TS809U-RP -> QNAP TS509 53,07 MB/s (nfs/LACP) 52,67 MB/s (nsf/no LACP) 70,66 MB/s (ftp/LACP) 72,29 MB/s (ftp/no LACP)
QNAP TS509 -> QNAP TS809U-RP 58,00 MB/s (nfs/LACP) 67,59 MB/s (nsf/no LACP) 69,79 MB/s (ftp/LACP) 70,37 MB/s (ftp/no LACP)

My conclusion:
The LACP don´t increase file transfer speeds.
These speeds are limited other componets (CPU, Memory, Controller, HDD).

My questions:
Working the LACP correct? (latest tests was done with firmware 2.1.5 on all NAS)
If the LACP working - in which situation can this feature increase file transfer speeds?

... maybe my thinking about LACP is wrong and this feature has another function ...

Hi rudku,

By testing with only one connection you wouldn't tell the difference when under the 802.3ad mode, instead you should test the speed with multiple connections to the NAS and the total sum of the transfer rates should be exceeding the limit of using single interface to transfer. Let us know the results then.

Rudku, wait until they release the next version which covers the different aggregation scenario's and then lets visit this again.....

thanks for answers

but according tests on server SmallNetBuilder Link aggregation don´t work correct...


Link Aggregation
NETGEAR has been kind enough to loan me a GS108T ProSafe 8 Port Gigabit Smart Switch so that I can test link aggregation in high-performance dual-ported NASes that support it. Since the 809 fits that description, I ran a quick test.

I first set the 809's Ethernet ports to "load balance" mode, which is supposed to support 802.3ad link aggregation. I then added the two GS108T ports connected to the 809's ports to a Link Aggregation group, then enabled LAG in the GS108T.

I then ran Vista Filecopy write and read tests using the NAS Testbed and another Core 2 Duo system running Vista SP1, but only a single drive (not a dual-drive RAID 0 array as on the NAS test bed machine.)

I first ran the test on each system individually, then with both systems running simultaneously. If aggregation is working properly and if the NAS under test is being limited by the capacity of a single Gigabit Ethernet connection, enabling link aggregation should allow higher net throughput. The test results are summarized in Table 4.

NAS Test Bed / System 2 / Total Aggregate
File Copy Write 92.4 / 57.4 / 149.8
File Copy Read 86.7 / 55.8 / 142.5
Simult. File Copy Write 56.3 / 41 / 97.3
Simult. File Copy Read 30 / 32 / 62

The results show no improvement from using link aggregation. The total write capacity of the two computers is just shy of 150 MB/s. But when both systems wrote to the 809 with aggregation enabled, throughput dropped for both systems and totaled only 97 MB/s. This is only 5 MB/s higher than the highest individual system write, which is within the margin of error of the test method.

Read was a similar story, with only 67 MB/s of total throughput out of a possible 97 MB/s achieved with both systems running simultaneously. This is again, only a slight (6 MB/s) gain over the highest individual system read speed.

I'll await feedback from QNAP and rerun the test if they have suggestions on my methodology. But, for now, it doesn't look like link aggregation will buy you very much performance improvement with the 809.


Detailed here:
http://www.smallnetbuilder.com/content/view/30831/75/1/2/

... so, I wait for same next firmware, where QNAP fixed this functionality, and then I retest it with minimal 2 connections and then I sum the total transfer speeds...

I've been working on this one too, for a long time. Even with 10 machines hitting the 509 its not reacting the way it should.

Well, we are all waiting for Firmware 3, which should usher in a new level of performance.
