QNAP TS-401T Turbo Server: slow 10MB/s with GBit

[chaos_prevails]

Hello,

we have the mentioned QNAP NAS and although I searched the internet back and forth I could not find a single page on it. It seems this hardware has completely disappeared from the web.

It is a 4xSATA NAS configured as Raid5 with two 1GBit ethernet ports which are configured as load balancing on a smart managed cisco SG200-26 GBIT switch with link aggregation activated for those two ports. When I connect my computer directly to this switch I still only get about 10MB/s when writing to the NAS. I thought probably the load balancing is broken, but the speed stays as low as 10MB/s with only one cable connected.

Can anyone help me out how to increase the speed somewhat?
- On the NAS, there is no further configuration possible concerning load balancing and as we didn't find any manual, I don't know which configuration is best on the switch-side.
- Also I didn't find any new firmware (currently Version 1.1.0 build 0425) which could probably bring some speed enhancements. Can somebody point me to a site? Or can somebody from QNAP help me out?

To make sure you know about which NAS I'm talking about, its this one:

Hi

It's getting tricky to find the archive NAS page unless you know where to look, but fortunately I've bookmarked it and thus found your model specifications here.

Hi Briain,

thank you very much, I didn't find anything because I thought the model is 40IT (40 + IT), but in fact it's 401T (401 + T). I know that I once searched for TS-401T but somehow I missed out on the results.

Through your link I found 1.1.0 as most recent firmware, but when googling I find 1.3.0 of 2007/2008 on the qnap ftp server (ftp://csdread:csdread@ftp.qnap.com/NAS/firmware/TS-401T). Is it save to install firmware 1.3.0, although it is not linked on the QNAP website?

Also, I didn't find anything about upgrading the RAM from 256 to 512 (I have a 512MB SD-RAM module lying around, don't know about the specs of the 256MB module though). Has somebody experience with upgrading the RAM of this/another QNAP NAS?

Yesterday I did a disk check + fix-errors via the webinterface and it went fine (3.28% non-continuous). I did not find any way to view the S.M.A.R.T. parameters of the disks via the webinterface.

I was wondering what else could increase performance somewhat. Could it help to delete and recreate the RAID5?

In the meantime I found the performance report of the TS-401T on the qnap ftp server and it mentions 30-60MB/s, depending on the amount of clients. So there should be some room inproving the performance of our NAS.

thanks again,
