Normal ACS Override does not improve on IOMMU grouping so no point using it. start my workstation VM). So if you disabled Global C State Control in the past and now seem to have some instability, maybe try enabling that with the latest BIOS.ĭo NOT use ACS Override with multifunction with unRAID version above 6.5.3 due to extreme lags. Unraid 6.8 (tested on rc7) has resolved the lags! □ That manifests as out of memory errors if I try to reserve more than 50% of RAM all at once (e.g. The latest Linux kernel + F12 BIOS seem to make disabling Global C State Control less stable. Start a new template if you need to switch on/off Hyper-V. Hyper-V apparently improves PCIe performance! So unless you are suffering from the dreaded error code 43 that cannot be resolved with any other tweaks, do NOT turn off Hyper-V by default. I guess if the overhanging card has the components just in the right place then it can lego itself. the Zotac GTX 1070 heat pipe is right on top of the U.2 connector and prevents the GPU from being slotted into place. typical GPU) overhanging the adapter usually won't work e.g. Using M.2 -> U.2 adapter on the M.2 connectors should be ok with single-slot-width PCIe cards on the surrounding PCIe slots.ĭual-slot width (e.g. VMWare Workstation works but with some crippling limitations. Virtual Box basically doesn't work due to terrible storage performance. Hyper-V doesn't work due to inability to pass through USB devices (with GUID) I attempted to run Unraid under a Type 2 Hypervisor and below is the short summary (TL DR: it's not recommended). This is incredibly annoying under heavy IO. ZFS (as of ) has a bug which causes it to not respect isolcpus. Likes: Pretty much take anything thrown at it and spit it output in my face.įuture Plans: Move to a smaller case (Raijintek Thetis?) for a more compact built.ītrfs can do snapshot! With a bit of scripting, you can achieve what znapzend does for ZFS. Primary Use: Main video/photo editing workstation + various unRAID stuff that people do on unRAID Unassigned offline backup / decommissioned: 10TB Seagate Ironwolf NAS, 8TB Seagate Ironwolf NAS, 8TB Hitachi HE8, 5TB Seagate BarraCuda 2.5" SMR, 2TB Samsung 850 Evo, 2050GB Crucial MX300, 512GB Samsung SM951 M.2 (AHCI variety) VM-only: 2x Intel Optane 905p 960GB (U.2 2.5"), Intel Optane 905p 380GB (M.2 22110) + 3x Samsung PM983 3.84TB (via Asus Hyper M.2 X16 card + split PCIe to x4,x4,x4,x4)įlash backup: Samsung FIT Plus 64GB (for rapid recovery in case main stick fails) Parity Drive: None because I trust the cloud GPU: Zotac GTX 1070 Mini for main VM, Zotac GT 710 PCIe x1 for unRAID, Nvidia Quadro P2000 for unRAID + transcoding Power Supply: Corsair HX850 (10+ years old!)

I had a i7-5820K (overclocked to 4GHz) and a Xeon E3-1245v5 server (ITX case) but it was more out of necessity since I wasn't able to afford Dual Xeon to merge them and still have sufficient performance. I finally pulled the plug when Amazon finally has my motherboard in stock. After a few months of researching, prepping my data, persuading she-who-must-be-obeyed, etc.
