    AM4 Socket Dimensions Help Needed

    Thanks for this post and thanks for the measurements! This is a big help for SFF builds such as the Ncase M1 with a Noctua NH-C14 as the NH-C14 just barely fits with an Intel CPU so it's nice to know it should clear with a Ryzen setup.

    Physical vs. Virtual FreeNAS + iSCSI vs. NFS: performance testing results.

    Yup all good points. I just set the "Pool Available Space Threshold (%):" to 80 and the Extent "Available Space Threshold (%):" to 50 so I think that will cover it. I also only used 50% of the Extent in ESXi for the datastore.

    Physical vs. Virtual FreeNAS + iSCSI vs. NFS: performance testing results.

    Thanks for the info. The issue is that when you use NFS and don't use iSCSI you can't use the datastores with VAAI, which is kind of a big deal IMO.

    Physical vs. Virtual FreeNAS + iSCSI vs. NFS: performance testing results.

    UPDATE: 400 GB DC P3700 came in. Results as follows: Ultimately decided run FreeNAS on the physical hardware and ditch virtualizing it because as you'll see below it runs so awesome that I've decided I'm going to introduce this this into a production environment at a client's site once I...

    Physical vs. Virtual FreeNAS + iSCSI vs. NFS: performance testing results.

    Yes it is really great considering it's got 14x HDDs, 3x SSDs, 2x 8 core 2620v4 CPUs, 4x DIMMs, LSI 3008 HBA, 2x 1400 watt PSUs. I was surprised, too. SFP+ would be nice for sure. I wish everything had SFP+.

    Physical vs. Virtual FreeNAS + iSCSI vs. NFS: performance testing results.

    You're absolutely right. I totally missed that. I'm ordering the 400GB DC P3700 and will re-run the tests at 32GB to see how that changes things.

    Physical vs. Virtual FreeNAS + iSCSI vs. NFS: performance testing results.

    Thanks for the feedback. Yes I did a little more testing and like you said, the DC S3510 is simply a poor choice for a SLOG device. The following screenshot is with the DC S3510 removed (no SLOG on the zvol) and sync=always so it's hitting the spinning disks directly on writes. Thanks for...

    Physical vs. Virtual FreeNAS + iSCSI vs. NFS: performance testing results.

    - Power consumption for the FreeNAS box: - The Xeon-D is really amazing. That thing is like 50 watts at idle, can take 128 GB RAM, is really surprisingly fast and works so well for a homelab ESXi VM host. Highly recommended. - No reason for 10GBASE-T in particular. It just felt easier...

    Physical vs. Virtual FreeNAS + iSCSI vs. NFS: performance testing results.

    Thanks for your feedback. I appreciate your comments. I was taking the screenshots for my own amusement and then I figured hey why not share it with the forum. Yes I also did notice that CIFS share do browse a lot more quickly, so that's always a positive.

    Physical vs. Virtual FreeNAS + iSCSI vs. NFS: performance testing results.

    Hi everyone, I've wanted to see how well FreeNAS would perform in back to back tests on physical vs. virtual hosts on the same hardware for a while now and finally have all the parts together to do some initial testing. My vision is to have a single box that can do it all for my homelab and...

    Rampage V Extreme CPU fan header and D5 pump.

    PWM was too low by default. I turned it up and it works great now. Thanks for the help everyone!

    Rampage V Extreme CPU fan header and D5 pump.

    Thanks guys. I'll try to disable Q-Fan on those headers and will report back. Also, the pump gets power from a molex plug and only gives the motherboard RPM signal via the fan header.

    Rampage V Extreme CPU fan header and D5 pump.

    Hi everyone, I have the Rampage V Extreme and two EK D5 PWM pumps. The issue I have is that when I plug either D5 pump into the CPU or CPU OPT fan header, the pump does not spin, it goes down to 0%. When I plug the pump into a chassis fan header, the pump runs at it should and goes to 100%...

    Supermicro backplane fan failure.

    The reason I think it's thinking it's a fan failure is based on my testing with the rear backplane. That is, when I unplug the fan on the rear backplane, the remaining fans spin up to full speed and a solid red LED light comes on, that reads fan fault on it. The front backplane has this...

    Supermicro backplane fan failure.

    Yes that's right. Light but no alarm, and the alarm definitely goes off when a PSU isn't connected so it works. The backplane seems to work fine, though as it detects drives without an issue. I'll have to check the backplane for the fan jumpers. I couldn't seem to find any fan control as it...

    Supermicro backplane fan failure.

    Yeah I'm sure it thinks there is a fault and yeah it has an audible alarm. The audible alarm goes off when you unplug a PSU so I can verify that's working. When I unplug a fan from the rear backplane after a few seconds the remaining fans kick up to full speed and the red LED turns on...

    Supermicro backplane fan failure.

    So I have a recently purchased Supermicro 847 JBOD and I have a little issue with the fans. It seems the fans that are connected to the rear backplane "spin down" after 15-30 seconds from power on, which makes sense because that's what pretty much all servers do after they POST. I also noticed...

    Supermicro 847 JBOD chassis questions.

    Seems like you can configure them how you wish, as they have 4x 8087 connectors on the inside, check this newegg link for the picture of the inside of the chassis. What I am going to do is run two cables to one dual port HBA on another server, as Blue Fox described in his post above.

    Supermicro 847 JBOD chassis questions.

    Thanks for all your help! I have one more question. How do the two JBOD backplanes on the 847 connect to the 4x 8088 connectors on the back of the chassis? I'm trying to understand how I can plug one 8088 cable into the JBOD chassis and yet still "see" both backplanes when I only have one...

    Supermicro 847 JBOD chassis questions.

    I am thinking I can go with a Supermicro 847 JBOD for a use in my homelab, non production environment, so I can build my 36x spindle disk array for media storage and also have enough room for 4x SSD's for an iSCSI VM datastore and 2x SSD's for ZIL and 1x SSD for L2ARC and am looking at the...

    Supermicro 846 / 847 chassis and power supply noise questions.

    Thanks for the feedback regarding the fans, that's good info to know. To connect the SAS expanders as you described, that would require the dual link expanders that are in the 847E16-R1K28LPB, correct? Are you able to use SATA drives with those dual link expanders?

    Supermicro 846 / 847 chassis and power supply noise questions.

    I was going to try the VM datastore with 4x spindles first just to see how it is, and if it's terrible then I'll go with 4x SSDs. Since it's just a homelab I am wondering if I can get by with regular spindle disks.

    Supermicro 846 / 847 chassis and power supply noise questions.

    That's great, thanks. I also asked on the FreeNAS forums and was reminded of a few more possible configurations: 4x drives in stripped mirror for the iSCSI target for the VMware datastore. (2 drives usable. Well really in this case 1 drive usable because it's not recommended to go over 50%...

    Supermicro 846 / 847 chassis and power supply noise questions.

    Thanks again for the tips on the eBay sellers, they're highly appreciated! OK so I've got another question for you... Given 36 total disks, which of the following ZFS layout configurations do you go with and why? 3x 11 disk vdevs in RAID Z3 with 3 hot spares (3 disks can fail per vdev, 3 hot...

    Supermicro 846 / 847 chassis and power supply noise questions.

    Perfect. I'll go with the E5-1620 v3 for the higher frequencies and not worry about the LRDIMMs. I'm not too worried about PCIE lanes as it will only ever have 1 HBA. Also noted about the eBay sellers and PSU's. Thanks again.

    Supermicro 846 / 847 chassis and power supply noise questions.

    Thanks so much, Todd! You answered all my questions, which I really appreciate. I'll definitely keep an eye out on eBay. As of now, I don't see any of the 846 or 847's E16's with SQ PSU's, but it would be awesome to get either one for cheap! As for the motherboard, CPU, and RAM options, I'm...

    Supermicro 846 / 847 chassis and power supply noise questions.

    Hi everyone, I am planning on building either a 24 or 36 bay FreeNAS ZFS SAN with WD 6TB Red drives and a single or dual 9211-8i HBA(s) with two SFF 8087 connectors per HBA, and want to use a Supermicro board and chassis. I only have a budget for 24 drives, but I figure why not get a 36 bay...

    Im burned out...

    I'm 32 and I've felt burnt out, too. I started playing games around the times of Wolfenstein, Doom, RoTT, Heretic, Duke 3D, Quake, etc on my 486 66 DX2. The feeling of things being fresh, new, scary, and genuinely fun had left me long ago. That is until I played the DayZ mod. I can say...

    Critique my NCASE M1 V3 proposed build.

    Hi everyone, I'm putting together an NCASE M1 V3 and wanted to go with a custom water loop that will include the CPU and GPU. I think I have pretty much everything listed, but let me know if you see anything that needs changing or looks off or not optimal. Also, does anyone know when the EK...

    Which ZFS layout would you use for the following, and why?

    Thanks for the tips! I didn't even realize the drives would not spin down with the ESXi datastore. I think I'll settle on the following: 2x 10 disk z2 zpools 1x 4 disk zpool mirror dedicated for ESXi datastore Thanks for the help everyone!

    Which ZFS layout would you use for the following, and why?

    Thanks everyone for the replies. With that said, I've narrowed it down to the following: 20 disks raid z2 = 2 zpools, 2 vdevs of 10 disks, 2 can fail per vdev, 4 can fail in total 32TB per zpool, 64TB total usable, 20% of total drives can fail 22 disks raid z3 = 2 zpools, 2 vdevs of 11...

    Which ZFS layout would you use for the following, and why?

    Good point on the different disks, thanks. What type of config would you recommend with smaller vdevs? Home use, 2-3 machines at once, media, personal files, ESXi homelab datastore. Non production, basically. Also, the server will have 64GB ram so I figured I could get by without ZIL and L2ARC.
