Sent you a DM if you still need a copy.

The title pretty much sums up my question. Many of you probably remember when the Xeon E5 v1/v2 processors dumped on eBay and became powerful yet super cheap options for home servers. For at least the last year we've seen the EPYC 7001 series processors on eBay for rock bottom prices as well...

I'd noticed that Seagate is missing from the show floor this year. Anyone have any idea why? I was going to ask a colleague of mine to visit their booth so as to shake hands and make nice. Is this somehow a consequence of Cray having bought some of Seagate's ClusterStor business?

Would you mind throwing the model up on Thingiverse and/or here? Might be useful for others to have.

I came here looking for a thread about SC16 and was not let down! Would you guys want to meet up tomorrow or Friday? @MatrixMJK @Patrick @everyone

Hey guys, I almost posted this a week ago when the price was $250 but now the price is even lower! This is an Enterprise class 6TB hard drive that hits a particular sweet spot for those that are warranty conscious. Newegg is offering this drive for $269 plus a 15% mobile discount until 10/16...

I heard about Pluribus Networks last week and found this switch on eBay for $1500. These switches run a complete (Ubuntu-based, I believe) OS and are highly configurable. I've no idea whether this is actually a really good deal or not but I'm sharing here nonetheless. Pluribus Networks PB...

I'd posted a while back about getting sFlow working on this switch. It's not difficult to setup and can help one visualize various types of traffic. First, go to Inmon.com and download sFlowTrend which is available for free. Next, run through the installer, start the client, and setup sFlow on...

It looks like Samsung Magician doesn't have the option to perform a Secure Erase in Windows 8 and above (including Server 2012 R2). Yes my colleague was using the same systems on which I'm testing and reproducing these issues. In my first post, I listed some of the hardware configurations with...

This drive finally did the thing. Thanks! I ran the tests on another system with 10%, 15%, 20%, and 25%. The drives with 10% and 25% also did the thing and the 15% and 20% OP drives followed suit a half-hour later. I fired up a new system and set the OP to 25%, 35%, 45%, and 50% (the maximum...

Thanks for bringing this up. I'd not bothered to modify or tweak the over provisioning until you'd mentioned it. All tests performed prior to the ones below were using the default drive configuration which does not allocate over provisioning. I just fired up a series of tests on three 256G 850...

Thanks for pointing that out. I forgot to mention that temps seem okay. The drives are in Supermicro systems supplied with A/C and steady airflow. I've observed them maintaining a temperature from 20C all the way up to 30C. So I don't believe I'm hitting a critical temperature threshold that's...

I've a handful or two of Windows Server 2012 R2 systems that can with some consistency, make various flavors of Samsung 850 Pro drives disappear from the OS. My test systems include a number of different hardware configurations. These includes combinations of Xeon E5 V2/3 processors with LSI SAS...

I've a couple hundred of the WD60EFRX that are idling at the moment between 31-38 C. These are in 44-disk Supermicro JBODs which are air conditioned with a moderate air flow. I've 100 of the WD6001FFWX in different Supermicro enclosures which idle between 26-30 C.

I had the same issue with a Supermicro motherboard purchased from Newegg. I ended up RMAing the board and getting a new one which worked fine. If swapping memory and processors around doesn't work, then you'll likely need to RMA the board.

This was a very helpful post, @izx !! Thank you. I've successfully flashed one MCX313A and two MCX314A (ConnectX-3 QSFP+) cards. Just a heads up for anyone else that comes along. If you'd like to switch between Infiniband/Ethernet/VPI modes, just use the following command: mst.exe status This...

I'd like a copy of the firmware if you don't mind ;) You should be able to upload it here as a file to avoid self-hosting. I'd tried numerous 40G QSFP+ cables with the Z9000, all of which worked fine. Part numbers (according to the Quanta T5016-LB8D into which they're now connected) ...

I started a similar project around the time that you first posted this. I've three systems, each with a Connectx-3, connected to a Z9000. My aim is similar to yours - to play with Storage Spaces Direct! My Z9000 is running the following firmware: Stack-unit 0 FLASH BOOT 8.3.11.5[boot]...

I'd tried the Mellanox Connectx-3 cards with the 4-to-1 (QSFP+ -> SFP+) cable but only got link on the first SFP+ cable. It may be possible to get this to work, but that's not a rabbit hole I'm prepared to go down at the moment. I was going to pick up a pair of XL710-DA2 cards, but my vendor...

Either one would have suited by needs at home but cost was the biggest driving factor for using the X520-DA2. For the office on the other hand, I was inclined to run some side-by-side tests between Mellanox, Solarflare, and Intel 40G cards. I seem to have found an answer as to why the...
