  1. The last time I asked for any kind of advice on the TrueNAS forums they absolutely laid into me about running 32GBs of RAM with 560TB of raw storage, citing their usual 1GB per 1TB rule. Despite the use case for my server being mostly Plex and no performance issues so far. RDIMMs were surprisingly affordable so I figured I'd max out the board. I likely won't need it, but I do plan to add another 360TB raw storage soon and switch to TrueNAS Scale, which I understand has more memory requirements than TrueNAS Core. Also, I have found myself with an AMD EPYC 7551 in a bit of a surprise ebay auction win. What do you think of a system using AMD EPYC? AMD EPYC 7551 SuperMicro H11SSL 256GB RDIMMs or less, doesn't really matter Thanks!
  2. What do you think about a system like this? CPU: Intel Xeon Gold 6148 Motherboard: SuperMicro X11SPL-F RAM: A-Tech 256GB 8x32GB DDR4-2666 RDIMMs Total around $880 for 20 cores/256GB RAM and plenty of PCIe lanes for HBAs & a GPU for transcoding.
  3. Wow, yeah, thank you for the suggestion. Looking on ebay for 1st/2nd gen scalable CPUs I can get a 20-core for around $110. Plenty of PCIe lanes to go around on a platform like that. Even including a dGPU for NVENC this route is looking cheaper than what I was expecting for a W680 based system.
  4. I am stuck with the case now, yeah, it's already paid for. I never really thought about dGPUs since I figured I wouldn't have the PCIe lanes for it. I'll look into that option. Is NVENC just as capable as QuickSync? I thought it was limited to two streams or something.
  5. Sorry, let me explain a little further. Before I migrated the server into this case I had a Norco 4224 and 3x LSI 9211-8i. Performance was great, and I had no problems. This same system scrubbed in about 2.5 days. When I migrated it to this Backblaze Storage Pod 3.0, it has special backplanes and controller cards, that are SATA port multipliers, not proper HBAs/expanders. Not only is it incredibly slow (22 days to scrub the same data) but the host OS occasionally complains of ATA errors. 15 drives each connect to a single multiplier connected to the host at PCIe 2.0 x2 lanes. Roughly 66Mb/s per drive before overhead. I would definitely like to just use HBAs, but finding a board with 4x PCIe 3.0 x8 lanes that also supports Intel QuickSync and ECC memory is impossible... best I have found so far is this board from SuperMicro, that has two running at x4 (but should still be enough bandwidth), but I've read this platform is not fully supported by TrueNAS Scale yet.
  6. Hey all, this one has kept me puzzled for quite some time. I currently have a 45-bay home server (an old Backblaze Storage Pod 3.0) but it is very slow. ZFS scrubs are taking 22 days to complete. I'm worried that if a drive fails, it will take too long to rebuild. So I have a Storinator XL60 from 45Drives heading my way. However, I'm struggling to decide how to attach 60 drives to a single host. 45Drives recommends 4x LSI 9305-16i HBAs, but to go that route, I would need 4 PCIe slots, and my current motherboard only has 3. I'm open to a new motherboard, even a new CPU/RAM, but I need QuickSync support, and even finding a motherboard that has both QuickSync, ECC, and 4 PCIe slots is proving challenging. The case has 16x SFF-8643 cables that run to the backplanes. So then I started looking into SAS expanders, but I've never used them before and with the parts I'm able to find it seems I'm either under the required 60 ports or way over. It just doesn't seem to work well. Also bandwidth is a concern as I can't seem to find a definitive answer on if using SATA 6Gb drives will drop the entire SAS HBA->Expander link to 6Gb or if it would still operate at 12Gb. Have any ideas?
  7. Yup, it certainly is. It still works, though.
  8. I was looking for a discount on Google, and these links showed up.
  9. I didn't see this posted anywhere else, so here it is! Synergy 2 Pro for $5. It does say for the Synergy 2 beta, but buying it will immediately unlock Synergy 2 pro on your account.
