    CX4111A Mellanox Connectx-4 LX SFP28 PP10R 25GBE Single-Port - USD $24.95

    Firstly @foureight84 , nice bracket design! I've had to make a few brackets myself in the past and never thought to make them flat & then bend and glue. Brilliant! Yeah, this...I think? I think the single port and dual port cards have the same chip and nothing special is done to fuse...

    Very good deal.

    My experience is limited here, seems to be just a marketing way to claim L3 while delivering only a subset of full L3 functionality. I don’t think “lite” is an actual standard though, so I’m sure the included features are going to vary from device to device. I have a cheap Marvell based 10g...

    512 GB Intel Optane DDR4-2666 RDIMM PMEM NMA1XBD512GQS

    I’m still setting up my two systems as time allows, but I can see the appeal for budget homelabbers who are OK with the limitations. The main one being speed. Someone here once said that at a certain point, pricing for hardware like CPUs and memory is based on supply rather than performance...

    512 GB Intel Optane DDR4-2666 RDIMM PMEM NMA1XBD512GQS

    As I understand it, when you use PMEM in memory mode, the DRAM works as cache for the PMEM and won’t be reported as RAM as all. So with two 512gb in memory mode, your system will have a terabyte (1024gb)...

    Workstation motherboard query

    To the best of my knowledge the mSATA form factor standard puts the mounting posts at the outside edge like that. Many manufacturers used just a single post on one side, like in the picture. I've never seen an mSATA device that didn't have the mounting holes on the corner(s) like that...

    Mellanox ConnectX-4 LX (Lenovo Branded), $20 Shipped. (Edit: Sold Out)

    In my case, of the four I bought, 2 came with what seemed to be current firmware and two needed an update. I went ahead and flashed all four with firmware off Nvidia's site. Worked fine without issues. PSIDs were what was expected according to Nvidia's Firmware download pages, and there...

    [FS] [US-ME]: Homelab gear

    Shoutout and bump for @bitbckt ! I had a great purchase experience. Easy to work with, items packed really well, shipped fast, work great. What more could you ask for?

    JBOD chassis control fans

    Edit: Oh, says right there that you have RC7s. Guess I'm not paying attention very well today. Plus, there's different model reducers. I'd assume that the ones with lower resistance values can probably handle more wattage without getting hot than the higher resistance ones? Do you know...

    <SOLD> [FS][US-CA][Sacramento] $150. Dell Precision T5820 and Navepoint 22U 2-post rack

    Glad there was already a sale pending on this BEFORE I saw it :p. I'm curious though, what's installed in the 5.25" Bay? Is it an 8 x Hot Swap unit for 2.5" SATA drives, or is it something else?

    Cheap / 3D Printed PCIe Cooler for the Supermicro 826

    That looks like it fits nice and clean! Added to my to-do list for the lab! In that orientation, do you know if the fan draws air in via the opening on the top, the bottom, or both sides at once? If it drew air in from below, and therefore across any motherboard heatsinks under it, it would...

    Gigabyte MF51-ES0 for an SSD NAS?

    Support on this Gigabyte board is very very very poor. Plus, the "manual" is literally a single page Quick Start Guide that wasn't even labeled well. That said, bifurcation works on mine. Only one of the x16 slots, but it worked for me. @JimmyBlack, which BIOS and BMCfirmware versions do you...

    KVM Troubleshooting

    Are you using the included 5v PSU? Looks like it uses enough energy (7.5w) that it won't power from one of the connected computers, even if you run a separate power cable from one of the Mac's USB ports to the power connector on the switch. Dumb questions...Keyboard and/or mouse are NOT...

    need suggestions to repurpose old Dell R920, T320, and T1700

    @Chriggel makes good points. I agree with them! All of it is old(er), although old is a relative thing. If you're coming from an i5-2500, all of this is going to be newer. T320 may be the best all around choice. 1356 was an interesting socket. A lot lower power draw than 2011, but you...
