Baseline is Synology for $758 w/ 5 x Seagate EXOS X20 18TB (3.5-inch drives) - Each Seagate EXOS X20 drive supports 6Gbps (600MB/s) sequential read/write speeds under optimal conditions. - Real-world performance is slightly lower, around ~220MB/s–250MB/s per drive for sustained transfers due to mechanical drive limitations. - The **Asrock B550M Pro4** motherboard and its **B550 chipset** offer support for **6 SATA3 ports**, each capable of **6Gbps (Gigabits per second)**, which translates to **~600MB/s** per port (theoretical maximum). - The B550 chipset is connected to the CPU via a PCIe 3.0 x4 uplink, which provides a total bandwidth of ~4GB/s (Gigabytes per second) for all devices managed by the chipset (including SATA ports, USB, NVMe, and other peripherals). - This means the 6 SATA ports share bandwidth with all other devices connected to the chipset. - The motherboard advertises **6 SATA3 ports at 6Gbps**, but these speeds are per port, not cumulative. The actual throughput depends on how the chipset allocates resources: - If all 6 drives are active and saturating their connections, they share the 4GB/s uplink to the CPU. - Realistically, the total available throughput for SATA devices alone is likely capped at around 3GB/s due to chipset prioritization and overhead. - RAIDZ2 (ZFS) offers dual parity, meaning 2 drives are used for parity, leaving 3 drives for data storage in your 5-drive array. - Read speeds can scale with the number of data drives, while write speeds are typically bottlenecked by parity calculations. - With RAIDZ2, read speeds can scale up to 3x the single-drive speed because data can be read from multiple drives in parallel. - Single-drive read speed: ~220MB/s - RAIDZ2 theoretical read speed: 220MB/s x 3 = 660 MB/s in ideal conditions - RAIDZ2 write speeds are typically limited to the speed of the slowest single drive due to parity calculations, so expect write speeds to peak around **~220MB/s–250MB/s** - For 5 drives in RAIDZ2: - Combined bandwidth: ~660MB/s for sequential reads (max) + ~220MB/s for writes, limited by the speed of a single mechanical drive. = ~880MB/s, or 7.04Gbps - These speeds will comfortably fit within the 2.5–3GB/s SATA bandwidth available through the B550 chipset. - The B550 chipset should handle the combined throughput of your RAIDZ2 array without issue, as the total bandwidth demand (~900MB/s, or ~0.9GB/s at peak) is well within the chipset's capacity of 3GB/s. - Your RAIDZ2 array's potential read speeds (600–660MB/s) are far beyond what 1Gbps LAN can deliver. - This means your storage array’s performance would be severely bottlenecked by a 1Gbps LAN, particularly for large file transfers or multiple concurrent users. - Considering read speed alone, 660MB/s equates to 5.3Gbps, which approaches but does not exceed the capacity of a 10Gbps LAN. - A 10Gbps LAN can handle up to ~1.25GB/s (1250MB/s) of data, while 1Gbps = 125MB/s total bandwidth. - This makes a significant difference for high-speed file transfers, streaming large datasets, or serving multiple users. - While your RAIDZ2 array's read speed (~600MB/s) fits well with 10Gbps LAN, it doesn’t fully saturate the connection. This means you'll only utilize about half the potential of 10Gbps.

It also provides memory protection from faulty or malicious devices - X570(S) has the best IOMMU groups (and can often passthrough at least 3 GPUs) and X470/X370 usually has two PCIe slots (and a M.2) for passthrough. Other AM4 chipsets can only passthrough one PCIe slot and one M.2 slot. - When multiple devices share the same IOMMU group, it means that they cannot be individually isolated and assigned to virtual machines (VMs). - With only one GPU, if it’s grouped with essential host devices, passing it through to a VM means the host loses access to those devices. - Advanced BIOS/UEFI features like **ACS (Access Control Services) override** may help split IOMMU groups, but the ACS patch is by nature a security risk because it pretends two PCI devices are in their own group when in reality they still are. As such, a guest given a device split by an ACS patch can still access the memory area of _**the other devices**_ in its real underlying IOMMU group, giving attackers of a compromised virtual system additional leverage in compromising the host. - Plex benefits from hardware acceleration for transcoding, especially with NVIDIA GPUs. TrueNAS Scale uses Docker or Kubernetes for applications, and GPU passthrough isn’t necessary because the GPU can be shared with containers. - If your HBA (Host Bus Adapter) or other storage devices work properly without needing passthrough to VMs or containers, IOMMU is **not critical** for your primary storage use case, which is NAS. - It seems like IOMMU is kind of irrelevant to my use cases since I'll be using TruNAS Scale, which focuses on Docker containers. But IOMMU is only important when running virtual machines. So I think I may be conflating containers with VMs. - VMs emulate an entire hardware stack, with allocation through a hypervisor. IOMMU is important in this case for PCI passthrough to isolate devices between VMs securely. - Containers share the host OS kernel and are lightweight, running applications in isolated environments on the same operating system. Containers use cgroups (control groups) in Linux to limit and prioritize access to CPU and memory, and they use the host’s drivers and APIs (e.g., NVIDIA Container Toolkit) to share GPUs, with the runtime managing access between containers. - X570 is a power hungry shipset. My 5700x with a X570 idles at 30 watts. With a B550 it's at 18. - The B550M Pro 4 only has one usable M.2 as the other one is switched off when using all of the SATA ports. - Limiting factors (like the B550's PCIe lane count) might shorten the system's relevance for future upgrades compared to X570. ### **Key Differences in Resource Assignment** |**Aspect**|**Virtual Machines (VMs)**|**Containers**| |---|---|---| |**Isolation**|Full hardware and OS emulation, complete isolation|Process-level isolation, shared kernel| |**CPU and RAM**|Explicit allocation, often static|Dynamically shared, limited by cgroups| |**GPU Access**|Exclusive via passthrough (requires IOMMU)|Shared access via drivers (no IOMMU)| |**Storage**|Virtual disks or passthrough|Shared volumes or directories| |**Use of IOMMU**|Essential for PCI passthrough|Typically irrelevant| --- You can use this utility on linux to check the ECC state if you have it active in the system: ``` # edac-util -v mc0: 0 Uncorrected Errors with no DIMM info mc0: 0 Corrected Errors with no DIMM info mc0: csrow2: 0 Uncorrected Errors mc0: csrow2: mc#0csrow#2channel#0: 0 Corrected Errors mc0: csrow2: mc#0csrow#2channel#1: 0 Corrected Errors edac-util: No errors to report. ``` --- b550: - ASRock B550M PRO4 $80 - an X570 like the Asrock X570M Pro4 could include 8x SATA ports, rendering the HBA useless (for now) - Does this mobo have ACS (Access Control Services) to improve IOMMU groups? - Apparently not according this reddit.

In reality, it probably won't be much of an issue. Read speeds over my local network will be an impressive 7000 Mbps. That's almost 1 GB per second. Write speeds are much more limited, though. My current wifi plan gets me ~550 Mbps upload and download, and only AT&T's $250/mo Internet 5000 Mbps plan could make use of ~70% of the array's read speed. Still, the machine is capable of direct playing 9 simultaneous 4K movies (at 60 Mbps each) or 36 simultaneous 1080p movies (at 15 Mbps each) on my current wifi plan. This is well within my CPUs capabilities since direct play is not CPU-bound. If transcoding is necessary, my 3070 is capable of 23 simultaneous 4K to 1080p streams, while my CPU is only capable of 8–12. Where do CPU thread counts come in? Even with 50+ users streaming direct play, the CPU threads may remain largely idle, as this task relies more on network and storage performance.\ Your CPU will handle **dozens or even hundreds of users** with ease since Direct Play is not CPU-bound. The system can handle dozens or even hundreds of simultaneous direct-play streams, while transcoding is limited to the GPU **Sequential vs. Random Reads:** - **Sequential Reads:** If only one movie is being served, ZFS can pull data from all data and parity drives, delivering close to 3x the speed of a single drive. - **Random Reads:** When multiple movies are served, each drive handles chunks of different files simultaneously. Total throughput decreases due to random seek overhead but remains high because of parallelism. --- Alt: - AMD Ryzen 7 3700X $ 90 (best value cpu) - AsRock Rack X570D4U-2L2T $400 (no 10gb or sata extensions needed) - KSM32ES8/16ME x2 (32GB ECC) $180 - Super Flower Leadex VII XG 850W 80+ Gold, Cybenetics Platinum + 3 fans ($155) - Node 804 $130 Total: $955 GPU, high TDP AsRock Rack X470D4U2-2T vs X570D4U-2L2T rack x570 2l CPU support: ![[Pasted image 20241121141232.png]] Which AMD chipsets support ECC ![[Pasted image 20241121164032.png]]
