bobfa Posted February 21, 2019 Author Share Posted February 21, 2019 IMG_1100.mov Up and Running! I have had the system up for a few days. The OS is running in RAM and Audiolinix is set for Extreme. The CPU is running around 30C. The server will be on the workbench for a while yet. I want to start testing the Fiber network card in the server. The HDPLEX200 is running the external FMC, disk drive, and the server. I have loaded the music in and Roon has finished fingerprinting! The power supply is fed with Transparent Audio power cord and filter. Completed system on the workbench. I have been busy with work, tax returns and customers! I have very limited listening time. Everywhere I play back from Roon from this server has a renewed/expanded depth. There is more detail. In some cases there is a different edge to the music that I cannot define. In others the sound just floors me. I listened to BT "Untitled" album twice. There were multiple times where something comes thru that I have not heard before. Sitting in my office right now listening to the desktop system and the music is painted on the wall behind the computer. This weekend I will have a couple folks over and we will get some serious time on the system. thuandb 1 My Audio Systems Link to comment
bibo01 Posted February 21, 2019 Share Posted February 21, 2019 @bobfa I noticed that you have a Startech fc card. When you install it, could you please report on your experience with it. Is it detected automatically, etc...? Thanks How curious are you? Link to comment

I want to do some listening to the server first. Just sitting in my office working now I hear things I am very happy with. I hope that AL will find it. Off to do some work to help pay for all of this! My Audio Systems Link to comment

I have asked because Startech is my planned card and I have AL. What do you mean by "I hope that AL will find it. "? You mean, recognize the card?! How curious are you? Link to comment
deanorthk Posted February 26, 2019 Share Posted February 26, 2019 Needed to say, your installation is inspiring. I would like to get back to music, slowly, and my first step will be to setup a server/streamer, and your setup seems just perfect for that. Link to comment
Popular Post bobfa Posted February 27, 2019 Author Popular Post Share Posted February 27, 2019 Here are this week's successes/failures/issues Issues: My server is running Headless AL in RAM. I have had one hard crash that caused a reboot. About 24 hours after I had synced batch of music I had a crash problem. I was checking Qsync (Qnap to Mac) sync software. The Roon app died on my Mac and the server crashed. I think that this is just weird. The second problem was on Saturday; The server was "wonky" and unresponsive to the client. I rebooted the server again. Failures: On Sunday I spent some time, not much, testing my SFP network card. I was unable to get it to go online, and I did not allocate enough time to debug it. Fiber direct networking will have to wait for another day and an EtherRegen for incentive! Successes: On Saturday my friend Keith stopped by, and we did some headphone listening to help him with some new cans and to grab some time on the main system with the new server. We only had about two hours; Keith had not heard the system with the new server. The time was short and I did not take notes. I kept hearing things I wanted to go back and listen to again. Keith noted the instrument placements and more around some of the classical music. Today I did an A/B/C test. A Sonic Transporter with HDPLEX 200 B Xeon server running off of the Optane C Xeon server is running in RAM. This test is a bunch of stair running as the servers are in the basement and the system is on the first floor. I only have one power supply, so it is stairs/reboot/stairs--listen. Good for an old man that needs exercise in the winter!. I have three albums that I am using for this exercise. Zoe Keating. "Into the Trees" -- Tracks: Hello Night and The Last Bird Joe Ford "Colors in Sound" -- Tracks. Cosine and Colors in Sound Copland Appalachian Spring; Rodeo; Fanfare for the Common Man (TELARC) The whole album I switched systems six times. I have been listening to the Xeon system running in RAM for about a week now, so I started with the Sonic Transporter. Just listening to "Hello Night" there are parts of the track that are just missing you do not hear them. You do not hear the bow on the instrument. Listening to "Fanfare" the orchestra collapsed. Playing off of my new server running off of Optane the soundstage on "Fanfare" opens back up there is much more depth. The strings are better isolated. BUT WAIT THERE IS MORE! Then there is "C" running in RAM. The two Joe Ford Tracks leap off of the speakers. The detail explodes. On the Zoe Keating tracks, there is much more detail around the bow and the strings on the cello. I am very pleased with the listening results. I am going to be working harder to understand the issues with AL crashes, and I have to tune the BIOS some more. WHEW! This week I will be able to spend more time just listening to music around the house. Oscarhuge and austinpop 2 My Audio Systems Link to comment
lpost Posted March 5, 2019 Share Posted March 5, 2019 Excellent work. Where are you viewing CPU temp? AL menu doesn't report CPU temp properly on my system, it read high. However, the command line 'sensors' does report the correct temp. Best to run 'sensors-detect' first and accept the defaults. It can be tweaked/name adjusted but it's usually not necessary. See https://wiki.archlinux.org/index.php/Lm_sensors On another note, I too had some strange crashes. I completely disabled and removed smb and nmb as I don't use them, preferring sftp. This cleaned up the core dumps caused by smb, see journalctl for log data. I also found that by slightly under clocking my RAM I no longer experience crashes. My ram modules are 'tested' for much higher refresh rate but I don't think this is necessary for audio use. And clearly, something between controller and ram modules was going wrong and crashing. Might be an area to explore in bios to reduce the speed. I too run a gigabit fiber network PCIe board instead of in-built Ethernet. My card has a Broadcom chip that AL already had a functioning driver compiled in the kernel. I can look up the precise model if it's helpful. Link to comment

Please let me know. I did not have time to debug the one I have Startec.com. PEX1000SFP2. IF you have one that work I will use it. My motherboard has two ethernet interfaces and I wonder if I have to disable one to do the bridge right. I do need some help in this area. I am weak and learning My Audio Systems Link to comment

If you are running a bridge then you would need to add your network card to the bridge. If for example your network card is at: eno1 you will need a file named : eno1.network in /etc/systemd/network its content should read : [Match] Name=eno1 [Network] Bridge=bridge0 If you type the command : networkctl you should get all the recognised interfaces.

I can do that when I get the card. I would like it if the AL Menu works for this and I will test that. The idea is to avoid command line if you can!! Makes it simpler for everyone.

Often, it's the simplest way to get things done, and you'll know what is happening vs. a menu with hidden commands. The menu is great for involved things like enable/disable ramroot but changing nic settings is liable to cut one off from the machine. Of course, have console access first, then edit the appropriate network files directly (or using the network manager as appropriate, I don't think AL has one but most variants do). Link to comment
the_doc735 Posted March 9, 2019 Share Posted March 9, 2019 hi bob, you seen this for ideas? https://www.pursuitperfectsystem.com/building-the-ultimate-music-server---hardware.html there is a lot of talk about PPA & JCAT stuff there, these are supposed to enhance audio quality, but not cheap! Cheers! Link to comment
the_doc735 Posted March 9, 2019 Share Posted March 9, 2019 Quote I will not count research time as that is endless. Actual construction and setup were completed over two days. I estimate about 10 hours of review, assembly, software configuration, and BIOS learning. As a reminder, I do this stuff for FUN. If this sounds like work, please buy a commercial server you will be happier! ....do you have any suggestions as to what could be a commercial (audio) server please? There are so many out there, the choice is bewildering and used ones seem to have decent low prices; something better than a NAS? thanks in advance! Link to comment
bobfa Posted March 9, 2019 Author Share Posted March 9, 2019 Paul, I have found several commercial music servers of interest. I have used several different kinds. 1. Mac Mini with and without the uptone audio power supply mod. 2. 27in iMac 3.Two different Small Green Computers Sonic Transporters 4. I am testing two custom built servers and two Operating Systems I have played with a couple of NAS devices as servers when I was using different server software. When I started using Roon as my playback system the NAS hardware did not make sense to me as they are mostly not as powerful as I would like. The rest of the system has improved so taking about server audio quality over time is a bit harder as I have not heard say the Mac Mini on the current DAC/AMP/Speakers cables. My Sonic Transporter i7 is a great sounding server. I improved the sound quality from the it by powering it with a linear power supply. My DIY server sounds better, but if you do not want to play with BIOS and OS settings this might not want to go this route. There are several other commercial servers that I personally find interesting. Innous and Wired4Sound are interesting. Aurender and Pink Faun are also very interesting. I am thinking about creating another thread about building servers in general. This thread is mostly about the specific server I built. There are several new threads on commercial servers in this section of the forum the_doc735 1 My Audio Systems Link to comment

There are several new threads on commercial servers in this section of the forum Thank you for interesting information bob. Much appreciated! Those server ideas are more like HiFi solutions and look interesting. I was thinking more of a computer/networking solution e.g. https://www.ebay.co.uk/itm/Dell-Poweredge-R610-1U-Server-2-x-Intel-Xeon-Quad-Core-X5570-2-93GHz-96GB-Ram/382826224500?hash=item5922389b74:g:gR0AAOSwEp5cUaya, is there any reason why something like this cannot be used to feed the rendu? I am assuming that this 'monster' would be superior to a NAS? NAS software hasn't been a problem for me and also makes clear sense. I don't mind playing with bios & O/S, and flashing things. Aren't things like Innous & Aurender terribly expensive though? Don't you have any interest in PPA & JCAT gadgets? Kind regards. Link to comment

Not to be underestimated so absolutely not recommended. Oh thank you! I thought on one of them that had the lid off in a picture I could see a whole bank of screaming tiny fans all the way across the front/back? Is the one I put up what you have called a data centre please? And also they have built in PSU's? (redundant?) One more possible thought/solution! What if you have a data centre but stick a FMC channel in the ethernet cable path, as the fibre apparently doesn't allow electromagnetic noise to pass through? Many thanks! Link to comment
Dutch Posted March 10, 2019 Share Posted March 10, 2019 A data center is a buidling or a room in a building housing many servers like the one you linked to, network equipment etc. in 19” racks. Space is a huge cost factor so these servers are made as slim (in height) as possible. This allows one to cram a lot of these servers inside a rack. This requires front to end airflows and thus the array of small fans. Small fans can’t move a lot of air unless they run at a high speed. High speed fans=noise. There’s many topics discussing FMC’s and optical fiber ethernet in general on this forum. Nothing new, just do a search. It’s off topic in this topic as well. the_doc735 1 System details Link to comment

Can you, in a nutshell and succinctly say why you believe your DIY server is better than the sonic transporter dedicated/purpose built device. The sonic transporter is surely built for Hi-Fi whereas your device could be just a general purpose server for many uses? On these forums I have read were members have said (more than once!) too much power = too much noise. Surely the sonic transporter addresses this issue with the happy medium? i.e. not too much power and resources, but just enough for the audiophile task. Many thanks. Link to comment

I'm pretty sure the ST is made from off the shelf parts - It's not purpose built in that sense. That's why it is priced so reasonably.
