I am confirming this. Cat 6 (Belden 2412) can be used for up to 55 meters (180′). When you exceed this length, you go to Cat 6A which can be used up to 100 meters. Cat 7 is not in the 10G specifications.
This applies to all networks, not just QNAP products.

Hello Creative Cow readers –
I hope that I have kept you entertained.Kevin Patrick contacted me. There were 2 problems in his system causing issues, that resulted in his slow speeds.
1) the latest QNAP firmware is not working correctly with his QNAP TS-873U-RP. After several tests with different firmware, we finally installed QNAP QTS 4.3.4.0569 from May 1, 2018, and now he is able to select MTU 9000
on the QNAP 10G card.2) the Ubiquiti 16 port 10G switch is unsuitable for these applications. Once we were able to select MTU 9000 on both the iMac Pro and the QNAP 10G port, we were still getting poor speeds. Because I am unfamiliar with all the menus in the Ubiquiti (for Jumbo Frame selection) – we simply bypassed the Ubiquiti US series switch and plugged the iMac Pro directly into the 10G port of the QNAP, and now we are getting 500 MB/sec WRITE and 1000 MB/sec READ.
I will continue to research the Ubiquiti 10G switch, but for the moment, I still stress the use of Netgear XS series 10G switches, or the QNAP QSW-1208-8C 10G switch.The end ! It’s all working.

It’s not broken. They are loading in the wrong firmware version.
Exactly what is it going to take for you to contact me privately ? Do you want me to send you money ?Bob Zelin

Hi –
ok, I did all the reading I could on the new “unreleased” TVS-872XT.
It appears that the TVS-872XT is the 2018 – 2019 replacement of the old discontinued (but wonderful TVS-871T, which is the QNAP that I first started with. I see no US dealers advertising the price, but on the UK Span website, it is selling (in 16 gig version) for about $2100, which is about $900 less than the TVS-871T sold for (and about $1000 less than the TVS-1282T3). I am no fan of SSD Caching or Qtier for video editing applications.So yes, based on my reading, the TVS-872XT, which has a built in 10G port and built in T3 ports, will probably be a better investment, and better value than the TVS-873e. So if you can wait, I would probably wait until it’s released.

QNAP gives me a headache. Let me assure you, if you wat for the TVS-882XT (which I don’t even see on their website – I have no idea of where you heard about this model) – 6 months from now, there will be another model.
Will it be better than the TVS-873e ? I have no idea. It LOOKS like it will be better – but I have never tested one (never even heard of it until you mentioned it). I can tell you this. I install QNAP’s almost every day. Some are great, and some are complete garbage. And I never know if they are good or bad, until someone buys one, and I install it and I either realize that ” this is great” or “oh boy – this is a real piece of junk”. I installed my first
TVS-873e (with optional LAN-10G2T-X550) at NAB 2018 just this past April. I was expecting nothing from this cheap box (I was used to installing the now discontinued TVS-871T, TVS-1282T, TS-1685), and had installed previously low end QNAPs like the TS-831X, and TS-1635, both which is are complete piece of garbage. But like every manufacturer – they make some great products and they make some crap. So the TVS-873e turned out to be great – and it was cheap. And it dramatically outperformed the TVS-453BT3 that QNAP was aggressively promoting ( a little 4 bay).So I never know until someone volunteers to buy one, and I get to install it. That is how I find out.
The 10G port in the TVS-882XT will probably be the same as the QNAP QXG-10G1T which is the Aquantia AQC-107, which is the same chip that Apple uses in the iMac Pro. Will the CPU’s perform properly on this new model, so it can handle video editing from multiple users ? I have no idea. Maybe – probably – but I can’t tell you until I try one.Bob Zelin

you are going to order the QNAP QXG-10G1T right now. End of story. You will spend the $89
plug the iMac Pro directly into the QXG-10G1T. Assign static IP address for the QNAP like
192.168.2.3
assign the iMac Pro a static IP address like 192.168.2.11
Jumbo Frames MTU9000 on both.Now do AJA Speed Test or Blackmagic Disk Speed Test. Now what do you get ?

ps – I use 10GTek Twinax cables all the time. They work great.

wow –
lots of opinions, without asking many questions.# 1 – exactly what QNAP model do you have ?
# 2 – QNAP checked your configuration ? There are a million configurations. Are you in a single static volume with all 8, 12 or 16 drives, or do you have a storage pool. And if you have a pool, is it thick volume or thin volume ?
If you have a 2 bay, 4 bay or 6 bay QNAP – forget it – you are wasting your time. I don’t care what the QNAP salespeople or your dealer told you. You MUST have a minimum of EIGHT 7200 RPM drives spinning in a single RAID group to make this work with speeds fast enough for video editing.#3 – how are you connecting to the iMac Pro ? The iMac Pro has a built in 10Gbase-T port. You should have a
10GbaseT card for your QNAP. All modern QNAP’s have the ability to accept a PCIe card. The QNAP QXG-10G1T is only $89. It’s the exact same Aquantia AQC-107 chip that is in your iMac Pro. Perfectly compatible.#4 – you said SFP+ cable issues ! So with your iMac Pro that has a free 10G port, you purchased a thunderbolt 3 to SFP+ adaptor. Well that is wrong. Now, for the moment, I am going to ASSUME that you do not have one of the larger industrial QNAP products like the TVS-EC1680U-SAS-RP, which is a 16 bay with a dual port SFP+ card that comes standard. I am going to ASSUME that you have purchased a cheap QNAP TS-832X, or any Annapurna ARM based CPU. These QNAP products are GARBAGE and no matter what you do – no matter what QNAP told you – you are NEVER EVER EVER going to get good performance from them. If you don’t have an Intel or AMD based QNAP with EIGHT drives, you are going to fail.
You could have simply asked me before buying, and purchase a TVS-873e for about $1250, and a QNAP
QXG-10G1T, plugged this into your iMac Pro, and you would be getting 1000 MB/sec READ (500 MB/sec write).Now, let me assume again that you purchase a QNAP Product that their own press says “is great for video editing” –
like the TVS-453BT3 – well, they are lying. This product is NOT suitable for professional video editing.
QNAP makes TONS of products that are wonderful (and so does Synology, and so does Netgear) – and at the same time, they make “budget” products that are ok for running Plex server, and your home videos from your iPhone, but are NOT SUITABLE for professional video editing.AND ON TOP OF ALL OF THIS – if you did not disable SMB signing on your iMac Pro and you are connecting via SMB, you are going to get crappy speeds.
Well – until you tell me the EXACT model that you purchased, and the exact model of SFP+ adaptor you have (and I sure hope its not an Akitio) – then I can give you further analysis of what your problems are. But like I said – if you have a 2 bay, 4 bay or 6 bay product – or if you have an Annapurna based QNAP product – it’s never going to do what you want it to do.
You buy the right product and it will be great. And QNAP makes some great stuff (and they make some not so great stuff).
OH – and take that Ubiquiti switch out of the equation until you get this resolved. It’s just adding more to the confusion of diagnosing all of this.

I’m having issues with performance between an iMac Pro and a QNAP NAS.
QNAP checked my configurations, found no issues.
QNAP ran some performance checks interally and determined the HW setup is fast.
QNAP ran some low level network test and confimed the slow performance I’m getting.
QNAP elevated the issue.I then talked to Ubiquiti, where they asked about the SFP+ cable I used. When I checked, I noticed that while it said it would work with Ubiquiti products, but no Mellanox. They did have another cable that would supposedly work with both.
QNAP is using Mellanox. Though to me, not work means nothing should work. My set up works, just slow.
