Thanks Can you point to where I can find this information so I can better plan what I will build. AFAIU XPenology rigs present themselves as existing DS models to the OS (DSM). Could an XPenology "DS918+" have 8 HDDs? Or do I need to use a different model to spoof DSM? I'd like to stay as close as possible to a DS18XX+ but AFAIR XPeanology rigs use all the same reference model. It use to be a 12 bay IIRC. Now it's the DS918+?

Thank you VERY much both @bearcat and @IG-88 for your valuable explanations and recommendations. I will need to take the time to study them in details. (I have no idea what multiplexing of sATA ports means, yet. Or HBA, or ...) What kind of bandwidth would each HDD require? @IG-88 you mentioned 1000MBps for 10 disks would be too little IIUC. How much bandwidth should I have for 8 disks? No matter what I do, there is no way I can give each of them the full 600MBps theoretical max of sATA3 unless I find some PCIe3.0 x8 sATA3 controller with 8 ports (if that even exists, or a PCIe2.0 x16, even less likely, I guess) AND I go without a dGPU (or only with a dGPU in a PCIe2.0 x4 slot). I wanted to avoid involving a dGPU in order to save some PCIe lanes: Asus P8B75-M LX : 1x PCIe3.0 x16, 2x PCIe2.0 x1 Asus P8Z77-M : 1x PCIe3.0 x16, 1x PCIe2.0 x4, 1x PCIe2.0 x1 Gigabyte ga-z87-hd3 : 1x PCIe3.0 x16, 1x PCIe2.0 x4 (The PCIe x4 slot shares bandwidth with all PCIe x1 slots. Both PCIe x1 slots will become unavailable when a PCIe x4 expansion card is installed), 2x PCIe2.0 x1 I don't plan to do any transcoding with this rig since it is not meant to be a media server but needs might change in the future and it may be worth being on the "safe side" if that doesn't become too inconvenient/expensive. What kind of dGPU would make sense? I mean if I wanted to do transcoding. I don't want to put a dGPU in here that would occupy space while not being able to transcode efficiently if/when I need to. Thanks again for your help Best, -a-

Hi I read that XPenology can run "on almost any hardware". Are there any known incompatibilities/limitations that I should know about to avoid any pitfall? For my first trial at XPenology, I was thinking of running it on the following hardware if this would be possible: - MB: Asus P8B75-M LX or Asus P8Z77-M or Gigabyte ga-z87-hd3 (this one supports 6 sATA3 6gbps drives) - CPU: i3-3220 or i5-3470 or i7-4770s - RAM: DDR3 1333 or 1600MHz - iGPU - sATA3 6Gbps controller: any >=8 ports PCIe card I could find. Like, Delock 89384 (jmicron) or Delock 90391 (Marvell 88SE9235, Marvell 88SM9705) OR maybe two 4-ports cards if they are easier to find... - HDDs: 8 Seagate Ironwolf 12TB sATA3 6gbps drives in RAID5 - PSU: would 400W be enough? (I have a 750W laying around if that is necessary). Synology PSUs for 8 bays are 250W but that's a different rig, obviously... Thank you very much in advance for your feedback. Best, -a-

Thanks a lot The nsc 810A looks terrific but is probably very difficult to build into I guess. The silverstone is unappealing to me. I have the Antec already somewhere. but it can only hold 6 drives (without using 5.25'' ->3.5'' adapters. I might consider repurpose this case though. In the meantime I found those from Fractal Design that seem affordable: (this one is convenient) https://www.fractal-design.com/products/cases/define/define-r5/black/ (this one is compact and probably very inconvenient to cable manage, especially the drive bay above the PSU) https://www.fractal-design.com/products/cases/node/node-804/black/ Or the meshify 2? https://www.fractal-design.com/products/cases/meshify/meshify-2/black/ Tx -a-

What's the C2000 chip failure? I'll look it up... Thanks for your replies

Hi guys :) I have an old ds1812+ (with 8 disks running in RAID5: 6 disks + 2 hot spares) that is used only as a backup destination (using hyperbackup) from other (more modern) Synology NASes. It was originally fulfilling a more important role but as time passed it became obsolete compared to other machines and thus ended up as a backup destination. The fact that it can hold 8 disks was obviously a big advantage here. Now this ds1812+ just died on me (all LEDs are off except for one or two disk LEDs. Fans spin as soon as the power cord is connected. Front panel is unresponsive), I tried to change the PSU since I had a spare one but it seems that it's the MB or something that went south... I need to replace that ds1812+, but I have a hard time accepting the idea to buy a brand new ds1819+ for that purpose. That would be a waste. And I don't have another (less recent) 8-bay that could replace it either... So I was thinking, since I only need the limited features (backup destination) maybe it wouldn't be completely nuts to go the XPenology route this time. This would also be a good way to asses if XPenology could be a viable option for me for other purposes in the long run. Kind of a pilot experiment or something... I guess I need to look into cases that can host 8 drives and a good amount of fans (I could probably repurpose all the rest of the hardware from older PCs or buy new parts if necessary). I was thinking ATX form factor but I'm open to anything that is not rack-mounted and that fits in a single box. Most modern ATX MBs have 4-6 sATA 6gbps ports, so I would thus need to buy an extra sATA3 controller in the form of a PCIe AIC (or should all drives be on the same controller for RAID5?). The main concern for me is that sleep works flawlessly since the machine would be sleeping most of the time (except during brief backup jobs from other NASes). I bet you all have recommendations about what hardware I should get. Please refrain from recommending hardware that is not currently available, though. Oh and obviously, the idea is to stay below the retail price of a DS1819+, not to have more perf for the same price since this machine would have a very limited duty anyways. I am also wondering if I could use the disks that are currently in my DS1812+ and move then into the future XPenology rig (just as I would migrate them into a DS1819+ had I purchased one) or if I would need to setup everything from start and restart all of the backups (losing the current file versioning history). That wouldn't be the end of the world but if I could avoid it, it would be convenient. I believe on an XPenology rig the OS is on an USB stick (that sound unreliable...) while on a Synology rig the OS is distributed among the HDDs. Maybe that makes it impossible to do what I just asked. Or not? Thank you very much in advance for your help and advice. Best, -a-

Dear all, I already own 2 DS1812+ and I was thinking in trying to install DSM on other hardware. I read some treads on this forum but it seems very confusing. There seem to be so many different versions (for a given version of DSM) and the differences between them are not clear (nor are the change logs that are only partial most of the time). There seem to be the "++" builds which supports more hardware and a "x64" build (does this mean the other builds are 32bits only?). In addition, I am not sure if there are versions for real hardware and others for VMs or if the same files can be used for both. As far as I can tell there is no build for DSM4.3 has of today (20131004), but I may be wrong since many treads seem to be "hijacked" and contain links for versions that do not match the title of the tread... Please tell me if I am wrong. This will sound very naive but I think it would be nice to have a sticky tread that would only contain links to the different builds available. Then each user could choose among them which one suits his needs best. Maybe there is already something like that and I missed it... Just let me know. Thank you very much in advance for your help.

Hello everyone, Is there a tutorial for beginners anywhere? Best, -a-
