  1. When buying a Supermicro make sure you get a SAS2 backplane ... which yours has. Also, the EL2 model means it has dual port capabilities (i.e. 2 x SFF-8077 connectors), giving it a lot of bandwidth. You can connect either 1 cable to the card, 2 cables for double the bandwidth, or 2 cables to do different cards, cascade the controller to a real external port. Check the manual for different connectivity options. EL1 may or may not support dual link - people on the FreeNAS forums say it does unofficially. Also, make sure all the trays come with the chassis - they can add up quick. Also, that both PSUs work correctly. Lastly, you may want to get a 1 to 8 PWM fan hub to connect the 7 chassis fan to the motherboard fan header so that you can control the speed/sound of the server. If you have the fans hooked up to the SAS expander, they run at full speed and are NOISY. Yes, the 4U SuperMicros can fit a standard ATX motherboard, you'll need a special chassis control panel to I/O port breakout cable (it's about $20 on Amazon/eBay) if you're not using a SuperMicro motherboard.
  2. I would get a 9207+ series, it uses PCIe 3.0 ... and in some cases cheaper than the classic 9211-8i which is PCIe 2.0. For hard drives it doesn't matter, but helps if you have SSD caches on the controller. I picked up my controller from the seller qbtl on eBay... his cards seem to be fine, been using a 9211-8i from that seller for about 3 years no issues and just ordered a 9207-8i (waiting for it to come in the mail).
  3. Even with a SAS2 or SAS3 port expander it should have full bandwidth per drive (about 125MB/s). If you get a dual port SAS2 expander that's 48gbps over 24 drives which is 250MB/s right (with SAS and PCIe overhead I guess around 200MB/s?).
  4. Aquantia based cards are pretty cheap and work well with unRAID. How much did you pay for your card?
  5. I don't have that option in my Unassigned Share screen - I can mount or unmount the NFS Share, auto mount, Log, and Script. I don't have the ability to mount the drive locally and share or not share. For example, if I have 10 NFS mounts, I may only want to share some and not others. I don't think this is possible right - it's either share everything or nothing?
  6. For the Unassigned Drive plugin, can you selectively choose which shares to export and which shares to hide? It seems to be currently a global option? Thanks.
  7. Hi all, I'm contemplating getting a JBOD enclosure to host an additional set of disks rather than get a large Supermicro chassis... but one thing was worrying me is how unRAID would handle the JBOD chassis going offline? For example, power fails on the JBOD chassis, unRAID would report these disks as offline. But assuming there was no data transfer, on next reboot, I bring the chassis back online, do a parity check, would the system pass? Afterall, multiple drives would have gone offline. In short, how does unRAID respond to multiple disks going offline temporarily? Thanks.
  8. Do you have the link to the station driver article? The direct download link is blocked. Thanks.
  9. It might be my SSD hotswap chassis (StarTech S25SLOTR) - I've removed it and directly connected my SSDs to the system - hopefully that stabilizes the cache drive.
  10. OK, it's not a cable failure ... and not a SSD failure, I replaced both and my ASM1061 on-board controller is still throwing errors. I'm wonder if it's a problem with the AsMedia Controller? Diagnostics attached. Thanks. nasserv-diagnostics-20180630-2213.zip
  11. Yeah, Mary flew from my movies folder into the children's movie folder. This is what I thought, that the move process and manual SMB move conflicted with each other. Probably good for LimeTech in future releases to lower the priority of the warning (or rewrite the message) so that it doesn't look so serious? @Squid Thanks for the reply.
  12. I was moving some folders around using SMB and I saw the following error popup in my logs: Jun 24 13:05:08 nasserv move: error: move, 396: No such file or directory (2): lstat: /mnt/cache/video/Movies/Mary Poppins (1964)/Mary.Poppins.1964.1080p.BluRay.REMUX.AVC.DTS-HD.HR.5.1-FantasY.mkv Jun 24 13:05:08 nasserv move: error: move, 396: No such file or directory (2): lstat: /mnt/cache/video/Movies/Mary Poppins (1964) Is this just a conflict between mover and SMB, or is there an underlying error? My data seems intact. No other errors in the diagnostic logs. Thanks. nasserv-diagnostics-20180624-1418.zip
  13. I think it maybe a cable failure that was causing my CRC errors. I was getting errors even after replacing the cache drives. I swapped out the cable and I think I'm good. As for the old 500GB EVO 840, I ran about 500B of data through it on USB 3.0 and it seems fine.
  14. I got the 250GB Intel 545S, it has 144TBW.
  15. You have to read the fine print ... 300TBW is on the 2/4TB models which is pretty bad for a drive of that size. The 250GB model only has 75TBW for the EVO 850. EVO 860 on the otherhand has like 2.4PBW for the 4TB models and 150TBW for the 250GB model. The Intel 525S and EVO 860 have the best endurance and warranty for consumer drives as far as I'm aware of at the moment. I ruled out Samsung because they only sell greymarket in Canada - the RMA process is awful here.
