ruffpl Posted March 19, 2020 Share #1 Posted March 19, 2020 Which one will be better for hw transcoding on Proxmox running with xeon e5v3 (2,4 - 3,2 ghz turbo)? For now I was testing DS3617 platform that can support 16 cpu threads. Another thing is that I need around 8 or even more sata ports. Will it be better if I use DS918 with newer kernel? From the table I read it support ssd cache but does it support at least 8 hdds and does 8 cpu threads will be enough for transcoding?

pmchan Posted March 19, 2020 Share #2 Posted March 19, 2020 (edited) Synology HW transcoding relies on Intel integrated gpu and your cpu doesn't have any, plus I'm not absolutely sure about that but from my understanding, HW transcoding can't be achieved with virtualized xpenology installation. So, you'll get software transcoding, whichever loader you chose and I suppose it will be OK as long as you don't try to transcode high bitrate 4K videos.

ruffpl Posted March 19, 2020 Author Share #3 Posted March 19, 2020 (edited) How many disks does DS918 support? Also is it possible to add more than 8 cpu threats in it? Edited March 19, 2020 by ruffpl Quote Link to comment Share on other sites More sharing options...
pmchan Posted March 19, 2020 Share #4 Posted March 19, 2020 (edited) default is 12 disks and regarding cpu cores, I don't have the knowledge to answer your question but did you take a look at this Proxmox tutorial? Nevermind, I saw you did post in this thread Edited March 19, 2020 by pmchan Quote Link to comment Share on other sites More sharing options...

DS918 and DS3615 - 8 threads (4 cores + 4 hyperthreads, or 8 cores if you turn off HT in the BIOS) DS3617 - 16 threads (8 cores + 8 hyperthreads, or 16 cores if you turn off HT in the BIOS). But most finicky with regard to hardware compatibility. You can add as many threads as you want to the VM but DSM won't use more than stated; it's a kernel compile limitation.

ruffpl Posted March 20, 2020 Author Share #6 Posted March 20, 2020 (edited) One more question. Can I " jump" from one platform to another if storage pool with data is already created? F.ex if I create Vm, pass-through all drives, put my data on it, but after some time I would like to try different Ds. Can new VM (with passed-through same list of disks) not going to format the pool? Ps. Will ssd cache work if I pass-through (some cheap) 2x ssd by sata or it have to be some nvme by pci adapter?

Don't use cheap SSD for write cache or you risk your data. Better yet, don't use write cache at all. Quote Link to comment Share on other sites More sharing options...
ruffpl Posted March 21, 2020 Author Share #8 Posted March 21, 2020 Thanks. I will give a try with 918 today. If I want to passthrough sata drives for pool do I need to write them also in synoboot grub.cfg or only in Proxmox VM config file? Quote Link to comment Share on other sites More sharing options...
dextm80 Posted May 17, 2020 Share #9 Posted May 17, 2020 hi guys, i've tried to load xpenology on my proxmox vm, but with no success. it is important set vid pid? and how can i set it on a virtual usb boot? thanks Quote Link to comment Share on other sites More sharing options...
