One of the PSUs I tried is my test bench PSU, so I know that's not the problem (it's actually connected to another build now and running with no problems). As for the short trick thing, can you share a video or something visual so I can get a better idea what you mean? I'll try the BIOS upgrade...

Yes, both 8 pin power connectors are connected. The motherboard is not in a case, it's sitting on a rubber mat. Are there any points on the mobo to put my multimeter to test if power/voltage is flowing to pertinent components? Is there a way to tell if the BIOS is just missing/corrupt?

I have a Supermicro X9DRi-F mobo that won't power on (and obviously doesn't display video nor POST), but IPMI works. When I plug in power, the PSU fan spins up for a second then stops. Pressing or holding the power button yields nothing. Pressing and/or holding the power button repeatedly like a...

Just noticed something on the link and speed of the Linkreal card itself. "pciconf -lvc" verifies all the U.2 drives are running at their full link and speed "link x4(x) speed 8.0(8.0)", essentially PCI-e 3.0 x4, but the card itself says "link x4(x16) speed 8.0(8.0)" which indicates it's running...

I know this is super late, but I have a Linkreal LRNV9349-8I (PLX8749 chipset, 8 port, PCI-e 3.0 x16) and Linkreal LRNV9347-4I (PLX8747 chipset, 4 port, PCI-e 3.0 x16). In my simple tests so far these cards each seem to max out at ~3500 MB/s read and write. Based on the results below, do these...

For SATA drives, try: smartctl -a /dev/sdX | grep "SATA Version is"

So far I've been using the StarTech.com and an off-brand single port U.2 to PCI-e 3.0 x4 adapter (U.2 drive installs to the PCI-e card itself). I notice a drive will sometimes be detected and mount initially in a consumer grade motherboard, but won't be detected nor mount ever again upon...

Ha! I totally forgot about the 4 channel thing. Thanks

Interesting. The official SFF-8643 to SFF-8643 cables also say 12G. I guess I can ignore the 12G part...?

I have U.2 NVMe 2.5" SSD drives. I'm looking to get the Icy Dock U.2 NVMe 5.25" to 4 bay enclosure which has 4 x SFF-8643 connectors. I'll connect those with a 4 port SFF-8643 to PCI-e 3.0 x16 card. The problem is, all SFF-8643 cables I see available are listed as up to 12G mini-SAS. I know NVMe...

I took a look, but it's a bit to digest. So all of the cards listed there work with motherboards that DO NOT have the bifurcation feature built-in??

I currently have 3 x NVMe U.2 PCI-e 2.5" SSDs each on it's own U.2 to PCI-e adapter card. I'd like to free up PCI-e slots and use dual or quad port x8 or x16 PCI-e adapter card(s). Posts I find regarding these types of cards are outdated, incomplete, conclude without a clear verdict and/or...

Does the transceiver and MPO cables mentioned in this post make the QSFP+ (40 Gbe) to 4 x SFP+ (10 Gbe) breakout ports behave like regular 40 Gbe port on the ICX6610 and ICX6650 models? Or does this transceiver & MPO cable combo only work on the normal 40 Gbe ports?

Did you end up buying this? If so, how did it turn out for you? Does the motherboard need to support bifurcation for both drives to show up? If you put them in RAID0/stripe does the read and write performance double?

I picked up a Quanta T1048 LB9A off eBay and having a hard time getting this set up to simply function as a smart or basic managed switch (with web UI). The only thing I've been successful with so far is assigning the serviceport an IP and enabling SSH server. It has U-Boot version 2009.06 (has...

Got a Quanta T1048 LB9A 48 port gigabit & 4 port 10 Gbe (SFP+) switch, but can't figure out how to reset it and configure it. I've tried various commands piecemealed from manuals and guides for similar models LB9 and LB6M, but I can't string together any success. I just need basic functionality...

I'm trying to speed test some Mellanox ConnectX-3 dual port 40GbE NICs on my LGA2011 servers (using a Linux live USB, System Rescue CD) and I'm getting this weird behavior where the assigned interface/logical name disappears (i.e., en25ps0) when I connect a QSFP+ network cable to a port. If I...

Thanks! Any recommendations on qsfp cables that never give you problems?

Can you get the 40 GbE speeds with a Mellanox ConnectX-3 VPI adapter in Ethernet mode or must it be in Infiniband mode? If the latter, can the required subnet manager software run in Linux or a docker?

I'm about to add my 2nd VM host (ESXi) and I will being add more hosts in the near future, so I figured I need to consider piecing together some shared storage for the VMs. I've been searching for a couple of days now, but can't find a concrete answer - I understand local storage for VMs will...
