That's honestly an even better deal assuming you actually needed the chassis and it wasn't in horrible condition.

I measured the 8C version via a metered PDU, with a single DIMM installed, with an M.2 optane and USB drive. I got: Powered off (only BMC active): 15W Idle in Debian 13, no NICs active: 45-48W (~22W is the CPU) Idle, with all 4 10GbE interfaces active: 53-55W Same but with one CPU core fully...

https://www.ebay.com/itm/178175413833 5 available as of posting. This is a pretty good deal. $200 gets you a neat flex-ATX Xeon-D board with ECC support, four 10GbE (2 SFP+, 2 10GBase-T), four 1GbE, IPMI, 12 SATA (or 4 SATA + 2 PCIe 3x4), and a couple PCIe slots, M.2 slots, and can be powered...

It's not quite that simple. AFAIK Ceph supports multipath for a single OSD, but it doesn't have a means to say "this OSD exists on multiple hosts but only one should be active at one time", unless that's a very new feature that I'm not aware of. I'm not sure that Ceph is even what you'd want...

Yeah, do what the poster above says. You can take any chassis (Supermicro or otherwise) with an expander backplane and run at least a single SAS cable between your server and the JBOD box (or more for higher bandwidth). If the backplane doesn't have an expander, use an 82885T expander in the...

Sadly, it looks like 1.74.13 is the most recent for my X11 boards. I'll look into generating custom certs.

Looks good! Hoping the idle power draw isn't too bad, this could be a great homelab setup for when you want more I/O but don't need as much raw compute.

I still use OpenWRT for routing. Linux tends to have better driver compatibility, performance is good, virtualizes well. My one complaint is that I don't do major upgrades in-place (I do a fresh image and copy configs over, then swap the network interfaces over to the new VM), since...

Have you confirmed that the card works with SAS/SATA drives?

That's not exactly how it works. What matters isn't the exact data path of the write, it's when the write is reported as complete. For a sync write, the write is reported as complete when it is written to the ZIL (which can be part of the main storage drives, or the SLOG device if one exists)...

Does it do the same within a booted OS? You should be able to see the backplane itself as a SCSI device (/dev/sgX) but not as a block device (/dev/sdX).

I don't think so, given that a 4TB NVMe would cost about $400 a few years ago. $100/TB was the norm before the golden age of secondhand $50/TB pricing.

It's more complicated than that. The underlying NIST report defines "consumer-grade router device" as: and says that: So the only way for them to get around it would be to make a router that can't be "installed by the customer" - but they would have a very difficult time making that argument...

Getting kind of OT here, but the Nortek dongle is Zigbee and Zwave in one package.

I think the issue is this: Notice it says "Routers forward data packets" - not the commonly understood definition of "forwards data packets based on layer 3 information". This means it could potentially include APs and even dumb switches, because those also "forward data packets". Hell, it...

That's the problem, yeah. Our best hope is stuff that can make the enterprise hardware usable in consumer platforms, like SXM to PCIe converter boards. Or maybe a Chinese company decides to start pulling chips off of boards and putting them onto new products as a way of recycling them.

Agreed. For example, my old E5-1650v2 when overclocked would pull up to about 160w. My Threadripper 7960X usually *idles* on the desktop at about 150w (it can't realistically get much C6 time due to background apps and such, but even when it does it's still ~100w). Sure, it's way more efficient...

What does "active backplane" mean in this context? I found some images of X5-2 backplanes but they look like normal backplanes.

Interesting, would you happen to know of any good switches that sit inside the case but have external ports? My main use is that I'd like to be able to hotplug a device into the host from outside, but without needing to have anything attached externally if I don't need it at the moment.

Bought a secondhand SMT2200 and some fresh batteries for it. Everything works, except that it seems to hover around 91-93% efficiency and I'd like to get that higher. I see that it has a "green mode" setting that I can toggle either via the front panel LCD, or the web UI (via AP9631 NMC). I can...
