I understand - the thing is, when reading/writing FreeNAS's share from Unraid, I get very fast speeds. The problem is reading Unraid's share from FreeNAS. I will try from a Windows computer and let you know.

Just an update: Testing read cache directly --> 2.0GB/s dd if=/mnt/cache/test10GB of=/dev/null bs=1M count=10k 10240+0 records in 10240+0 records out 10737418240 bytes (11 GB, 10 GiB) copied, 5.3521 s, 2.0 GB/s Testing from cache via "user" share --> ~1.0GB/s dd if=/mnt/user/test10GB of=/dev/null bs=1M count=10k 10240+0 records in 10240+0 records out 10737418240 bytes (11 GB, 10 GiB) copied, 10.8258 s, 992 MB/s Testing from NFS share (keep in mind local IP for 10GB adapter is 192.168.100.200) mkdir nfs_unraid_test mount 192.168.100.200:/mnt/user/Movies/ nfs_unraid_test cd nfs_unraid_test/ dd if=test10GB of=/dev/null bs=1M count=10k 10240+0 records in 10240+0 records out 10737418240 bytes (11 GB, 10 GiB) copied, 13.8409 s, 776 MB/s However, when testing from the FreeNAS machine (Unraid mounted over NFS): dd if=test10GB of=/dev/null bs=1M count=10k 10240+0 records in 10240+0 records out 10737418240 bytes transferred in 3.015465 secs (3560783549 bytes/sec)

Thanks - I've tried #1 - and it helped provide a 10% boost (actually included that in the numbers I posed above). Also tried #2 - for some reason it made my transfers slower. In the description above, it went from: A <----- ShareB = 200MB/s (read) A ----> ShareB = 300MB/s (write) To: A <----- ShareB = 150MB/s (read) A ----> ShareB = 200MB/s (write)

Hi, I recently built a new Unraid server - see my post here: link. I'm having trouble reaching 10Gbit speeds on Unraid via a the share. Internally, I test the drive speed and get much faster results - see below: I have two test computers, one running Unraid (new build), and one running FreeNAS (existing computer).The Unraid computer has a 512GB Samsung 860 Pro NVME drives, which is capable of >3GB/s read and ~2GB/s write (verified via dd if=/dev/zero of=test10GB bs=1M count=10k) Computer A: FreeNAS, with 10Gbit card --> NFS Share "ShareA" Computer B: Unraid, with 10Gbit card --> NFS Share "ShareB" When reading/writing to NFS on FreeNAS, from Unraid, I get 800MB/s+. For example: B <--- ShareA = 900MB/s (read) B ----> ShareA = 800MB/s (write) The problem is when I read/write to Unraid's share. A <----- ShareB = 200MB/s (read) A ----> ShareB = 300MB/s (write) As mentioned above, when I go locally on the Unraid computer and write to the NVME drive, I get >3GB/s for both read and write. Additionally, when I try and use the NFS share locally on Unraid, I get slow speeds (B <----> ShareB) - around 400MB/s. As such, it seems like it's related to the share, rather than the disk. Any help would be greatly appreciated - thank you!

Much appreciated. I saw that case, but it's pretty ugly IMO. Aesthetics don't matter that much, but if I choose a tower I prefer a "cleaner" look.

I believe Plex currently cannot do GPU transcoding - I was saying hopefully they support it in the future. They currently have limited support for hardware transcoding in CPU see here: https://forums.plex.tv/discussion/250946/plex-media-server-hardware-transcoding-preview-1-4-0 Thanks for your recommendations regarding drives and cases!

Firstly I want to thank you for your very detailed and informative response. I agree about Kaby Lake being a good idea for HEVC 10bit, but the problem is I need the horsepower for other VMs too. The E5-2683 has a passmark of 18,000 and I'm getting 2 of them. Hopefully in the future Plex will allow for easy GPU transcoding and then maybe I'll buy a dedicated GPU to transcode H265. Regarding hard drives, perhaps it is best to get 8TB drives, especially since I will have 24 drive bays. Do you think it's worth paying extra money for the "pro" version that comes with a longer warranty, better reliability, slightly higher speeds (even though you mentioned speed doesn't matter to you that much)? I will look into the case recommendations. I was looking at towers as well, but each drive cage really adds to the cost, eventually landing at the Norco price with all of the drive cages.

Thanks for the advice regarding Marvell chips - I wasn't aware that they were undesired chips. Does it matter that the card is PCIe 2.0? Will the bottlenecks still be the drives? Regarding Plex and 10-bit HEVC decoding, I am aware that Kaby Lake CPUs support it, but I'm not sure it's supported by Plex yet (I could be very wrong). Also, I wonder how many streams hardware acceleration would be able to support simultaneously. I understand that the 10TB drives are higher $/TB, but they do provide higher storage density. Given the lack of striping with unraid, my guess is that I should shoot for 7200rpm vs 5400rpm. I've been searching for a Supermicro 24-bay case on ebay for some time but haven't managed to find something at a reasonable price. Shipping always makes it prohibitively expensive for me. Out of curiosity, which tower do you use to get you 25 drive slots with the 4 x 5in3 cages?

Thank you!

Hi Unraid community, I am planning a new build and I was hoping for some feedback on my part choices, and any suggestions you may have that would be better. I realize that I have a lot if information below, and that answering/commenting on everything would be difficult, but any suggestions would be appreciated! Requirements I have not used Unraid before (currently using FreeNAS with 2 x RAIDZ6 vdevs... 60TB raw which is 90% full), but I like the expandability that comes with Unraid. In doing so I realize that I am sacrificing the speed that comes with my current 2 x RAIDZ6 setup. My plan is to put the data that doesn't require speed on Unraid, and put the more speed-sensitive data on FreeNAS and have them connect via 10Gbe. Having said that, I would like: To start "small" with easy drive expansion (ie. buy a few drives, and buy more as I fill up the space) TONS of horsepower for Plex and various VMs/Dockers My current FreeNAS server has a CPU that is around 9,500 passmark and it was able to handle 8-9 streams at once (not all 1080p) but I often find the CPU being near capacity New build needs to have much more horsepower as I will be shifting my Plex needs onto the new server's beefier CPU Since I am planning for this server to last me for years to come, Ideally it should be able to transcode a few HEVC 4k streams Fast NVMe storage for cache and VMs (likely will put more than one NVMe drive in the future) 10Gbe IPMI for easy management Build CPU: 2 x E5-2683 v3 (OEM from ebay, used) CPU Cooler: 2 x NH-U9DXi4 Motherboard: Supermicro X10DRI SAS Card: 2 or 3 of either the LSI 9240-8i or the Supermicro AOC-SAS2LP-MV8 (not sure what the difference is - question below) Case: Norco 4224 RAM: 64GB (4 x 16GB) Registered DDR4-2133 Memory 10Ge card: Connect X-2, or any other SFP+ card - question below NVMe: Samsung 960 Pro NVMe 500 GB NVMe PCIE adapter: StarTech PEX4M2E1 M.2 Adapter Drives: still unsure about this one - question below PSU: Corsair - Professional 1200W 80+ Platinum Norco 120mm Fan Bracket (to make it quieter) Additional fans: 3 x Noctua NF-F12 The required SAS/Sata cables to connect everything Questions Is there anything that I'm missing in my build? Anything that you would suggest to make it better/more efficient? I've seen people mention "maxing out the backplane" in various places. Would my current build do so, or would using the SAS cards remove the bottleneck? Haven't seen this explicitly answer before, but if I start with single parity can I move my array to dual parity down the road? Or do I have to start with dual parity from day one? Am I losing speed by using a PCIe M.2 NVMe adapter rather than having it on motherboard? Which 10TB drives are recommended? Seagate IronWolf Pro, HGST, WD Red, Red Pro, Gold etc? Any other recommendations for 10Gbe card? Does it really matter which SAS card you get? Would I need to get 2 SAS cards and use the 10 built in SATA ports on the MB? What is the best practise?
