    Supermicro AOC-SLG3-2E4 - $25

    It may be "just a switch card", but they can vary in terms of things like hotplug, backplane management, and SMBus support. Some of the cheap AliExpress specials don't do those things well (or at all).

    Supermicro AOC-SLG3-2E4 - $25

    The reasons you'd use these are: 1. Hotplug - your BIOS still needs support for hotplug events if you want it to work properly, and needs to reserve enough resources, but this will get hotplug working even if you don't have any slots with hotplug controllers. 2. Does not require bifurcation. I...

    Supermicro Industrial Atom E50-40 SYS-E50-9AP-N5 Goldmont Server 29130EC Brand New $75 $8.00 shipping

    I regret not buying a few more of these at $75. I'm using one for home automation (openHAB) and the other as a media box connected to a TV. Seems fine for 4k video via VLC, but YT videos are realistically limited to 1080p or they'll stutter.

    Multi-NVMe (m.2, u.2) adapters that do not require bifurcation

    Presumably, you have to use switches to connect more drives. But don't buy tri-mode. They tend to just expose the NVMe drives as if they were SAS drives. Performs worse because you don't get the NVMe software stack. They have a few advantages, like being guaranteed* to support hotplug...

    Is it normal UPS batteries degrade so much?

    Funny story, I actually had a UPS reporting bad batteries only 8 months after a battery replacement. Turns out, one of the connectors had some lose, so the 2s2p configuration was effectively 2s1p. Whoops. Speaking of, what "good" brands do people use for replacement batteries?

    MS-01 HBA / NAS expansion Question

    16 NVMe modules would require 64 lanes to get full bandwidth. You're not getting that out of an MS-01 without some kind of switch card. If you want to go for the DAS route, you'd need to put an external PCIe adapter in the MS-01, and then some kind of external PCIe switch/jbod to house the...

    Can't decide on a TRX50 board

    I'm using the Magnitude sTRX4 D-RGB block, Manifold 2CPU 2GPU for distribution, Kinetic FLT 240 D5 PWM D-RGB pump/reservoir, and P360 radiator. Also running quick disconnects for the CPU block (and for the GPU later). The EK QD kits are just Koolance QD fittings. If you just buy Koolance parts...

    Can't decide on a TRX50 board

    Cooling is full custom loop. Right now I only have the CPU in the loop, but I plan to watercool the GPU as well when I get a new one. Unfortunately the loop parts are all EK currently, so I might end up with mismatched parts unless EK somehow turns it around. I'm using the board's built in...

    Yet another quest for 10Gbps routing capable mini PC

    I will chip in and say that I was able to benchmark my Xeon D-1541 at just under 20gb/s of simple NAT routing in a VM, but YMMW since it can depend on a lot of things. However, that's only 35W less than a 1220v3 assuming it's maxing out the TDP.

    Steam and Blockdevices need directions.

    Don't forget to set HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\EnableLinkedConnections to 1 (DWORD).

    Steam and Blockdevices need directions.

    > the use case is, Steam games most of them need to be on a block device, just a given fact. I need a block device shared between Clients and dont want to make multiple Block devices with the same Data on it. Which games are those? I have most of my library on an SMB share, and I haven't run...

    12 Bay NAS Case Project

    There are some low profile GPUs. These cases generally aren't *bad* if you want something with that kind of drive density which is quieter than a rackmount and has a smaller footprint. Just keep in mind you're not going to get the bells and whistles like the high efficiency PSUs and managed...

    Server case and motherboard for 25 sas ssd + 6 SSD Nvme U2 + 2 sata ssd

    With that number of drives + currently having two servers, at that amount of storage I'd definitely consider Ceph or something else that would allow you to cluster them. If you really want it in a single server, there's a few Supermicro options that would *mostly* fit, but the main issue is...

    Readily available / affordable HBA with both internal and external connectivity?

    You don't even need the 16i HBA. The backplane itself has four x4 ports. Use two to connect to the HBA, and two to connect to external shelves. It's also cheaper to buy an expander with internal and external ports like the 82885T (8 external, 28 internal, can optionally use a pcie slot for...

    JBOD chassis control fans

    The SES method only has a chance of working if the fans are in some way connected to the SAS expander itself, like if the backplane has fan headers. Some older ones (usually 6g SAS) do. But as said, your best bet is probably to either replace the fans or whole fan wall, or get the absolute...

    SuperMicro Backplane I2C Cable

    The only header that would make sense would be JIPMB1. JPI2C1 is specifically for the PSU, and JNVI2C1 is for NVMe backplanes. If you want SAS drive information to show up in IPMI, you might be able to do so with a supermicro SAS HBA that specifically supports IPMI management.

    Cheap External 5 Bay Sata Enclosure?

    You can build your own external JBOD chassis for a reasonable price nowadays. Get a cheap 8-bay NAS case, throw a SAS expander in it, put a SAS HBA in the desktop. But at that point, you're better off just using that as your actual case.

    Supermicro motherboard 13th gen with AMI bios - delay PCIe bus enumeration

    Does the switch chip on the card show up in your pcie topology even if the card itself appears to not be working? Have you tried a pcie rescan after boot?

    SAS, SATA, U.2, NVME, MiniSAS, HBA or RAID, OcuLink?? - Lost in Diversity

    SlimSAS, SlimSAS LP, and MCIO all have both 4 and 8-lane versions. MCIO also has a less-common 16-lane version. A. Theoretically, yes. Not common in practice. It's not rated for those speeds. B. If it's truly a SAS/SATA-only backplane, it won't work at all. U.2 backplanes use a separate set of...

    Example of bridging across multiple SR-IOV links-- with one unsolved routing problem

    If PC1 can ping PC2, but not the other way around, it sounds like maybe somewhere, there's a NAT rule when it should just be plain non-NAT routing. Without any sort of connection-tracking like with NAT, a successful ping would need correct routes in both directions. Maybe there's a duplicate IP...
