I thought the shield could natively decode 4k (h265)?
New Media Server build (feedback welcome)

the server could do the heavy lifting, but I think the bandwith would be my bottleneck, is that correct?
If you can stream 4k over the internet, good wireless should be able to handle it too.
do I need that crazy beefy motherboard, or should I consider something non-Xeon related?If you don't transcode, you won't need it. It might be cheaper to buy firetvs (not sticks) instead of expensive server board. Just about any modern cpu can stream a few 4k streams that aren't transcoded. I have all of my firetv's wired and my Celeron J1800 box running OMV has no problem streaming HD to five+ devices.

If you are going to have VMs, I would look at e3 xeons on a supermicro or asrock rack motherboard.

Have you done anything with link aggregation on any servers you have built
I haven't since my switch doesn't support it but plenty of people on the forum have. On the other hand, my servers have no problem saturating gigabit.

Is there a tutorial somewhere on setting up SnapRAID and MergerFS for OMV specifically?
SnapRAID Plugin Guide
mergerfs is easy. just add the drives to a pool.So I read that SnapRAID can support up to 6 drives
6 parity drives. It can handle a lot more drives than 6.
I should have a parity drive OUTSIDE of the pool correct?
I wouldn't put any parity drives in the mergerfs pool.
And does SnapRAID/MergerFS have a tolerance of only losing a single drive?
It can handle the loss of drives equal to the number of parity drives you have. If you lose more than that, you only lose the data on the failed drive.

rye,
Thanks for that explanation. So say I had 6 drives that make up my pool, and have 2 drives for parity, I could stand to lose 2 drives and recover correct? And as far as the initial setup of the drives, I'm assuming that I setup the drives in the snapraid first, then install mergerfs plugin and tell it what snapraid pool to look at and the 2 drives for parity, is that right? Sorry for the noobish questions, this is a lot different than what I'm used to

yep. The snapraid manual is very good for explaining how to recover.

The plugins really don't know about each and order of configuration doesn't really matter. So, install the plugins. Add the six drives and two parity drives to snapraid. Then add the six drives to a mergerfs pool. Other plugins should use the mergerfs pool but not snapraid.

rye,
Perfect that's awesome info, I think I understand it now. Now I just need to figure out how much money I need to save up to build this beast
So if I wasn't going to run VMs off the server and only used it for media streaming, autodownloading (with Sonarr, Radarr, etc), do you recommend going with a much cheaper Intel board, if I could still do everything ungimped with my larger 4k streams in the future?- Aitrus

A cheaper system would work. If you had an old desktop system laying around, you could try it.

nope, SnapRaid can support more then 6 drives, unless you mean 6 parity drives than yes it can only support hexa parity. 6 parity drives for up to 42 data disks with multi drive failure protection
and I am sure you can go beyond recommended numbers
Snapraid works different. here is some basic explanation from SnapRaid FAQ pagefor Single parity disk you can protect 2 to 4 data disks with a single disk failure protection.
for 5 and more you need at least 2 parity disks.
hence with single parity setup would be 3 to 5 disks where 1 is dedicated to parity.
as in 1p + 2d or 1p+3d or 4d
also Parity disk MUST be the largest in the set. as in, if you use 2TB disks for data the parity MUST be at least 2TB or larger.1/Single Parity/RAID5 2 - 4 2/Double Parity/RAID6 5 - 14 3/Triple Parity 15 - 21 4/Quad Parity 22 - 28 5/Penta Parity 29 - 35 6/Hexa Parity 36 - 42 furthermore, while you can pool drives into single volume using SnapRaid it is mostly recommended to use other pooling software like mergerfs or a like.
in OMV all of this can be setup using plugins from the webUI.
install SnapRaid plugin and unionfilesystem plugin. from omv-extras
configure snapraid as you want. all is done from omv WebUI.
than configure unionfilesystem pool (version 3. and up only uses MergerFS for the pool)each is totally independent from each other and can be setuped in any order you want, you just need to remeber that you should not be using parity drives with in the mergerfs pool.
so if you have 6 disks and you will be using 2 of them for parity, just skip them when building the pooled volume.what I do is I give my disks label like dX or dataX for data drives and pX or parX for parity drives where "X" is the number of the disk.
so my setup looks like
disk p1,p2,d1,d2,d3,d4
mergerFs volume pool all d[1234] into single volume "maindata" -
I would say when you get your drives, record the drives Serial numbers
than once plugged in CLI blkid will give you the data you need.
maybe something on WebUI disks page will help also.
depending on your case, try also record where each drives is located within the case.
I have the SM 846 24 disk hot plug chassis , each is numbered so I can find things easy enough. -
If you want 4k streaming with a hw capable kodi client I can recommend my box which is a beelink mini with s905x soc. It has hdr support also. Disadvantage is that it has fast Ethernet. I haven't encountered any issues with my 4k samples, but if you ever have bandwidth problems there is known a USB gigabit Ethernet adapter that it has been tested to reach 35MB/s more than an enough for high bitrate 4k videos.
Brand is not really important as there many brands shipping boxes with the s905x soc.
Look at the libreelec amlogic forum section. -
