I find it kinda wild that Dell sells an iDRAC controller for twice the price of a lot of motherboards.

There is a reason we fight the dumb fight with the BMC cards and buy per outlet switching PDU's.

Having a vga and other ports relay would be useful too sometimes, but mostly the power cycling is all we need for doing power/reset testing. Truly this is all you need - something to jump/unjump the NMI button.

We do the per port power control pdu too but try to usually power off gracefully. Digital logger is the brand.

FWIW, you could do this with an ESP8266 and a relay module for probably less than 20 bucks. You'd have to do a bit of Babby's First Coding, but it'd be pretty easy.

Right? We're legitimately trying to find a purpose we could apply them to--even just like dev boxes for test environments, since it seems like such a monumental waste. Fun fact: a lot of datacenters will literally just shovel old hardware into garbage bins that end up in the local dump. We may or may not have "liberated" 100+ power cords from such a bin when we found out we'd accidentally ordered all our new servers with the wrong ones.

Following my earlier post I started looking at Ivy Bridge Xeon E3s, and then saw that a Haswell system wouldn't be that much more for better idle power consumption. How is this deal for the following CPU/RAM/MB combo for $220 after shipping? CPU: Intel Xeon E3-1240 v3 CPU Cooler: Intel Stock Cooler Motherboard: Supermicro X10SLL-F Memory: 16GB DDR3 1333 ECC Unbuffered (2x8GB)

It's about right. E3-1240v3 goes for about $75, the motherboard is about $100, and add another $60 or so for the RAM.

Eh I won't fight it at home, the only thing that doesn't have IPMI [supermicro] is the xserve that I have sitting around for a very select few legacy things I do occasionally. At work every single slot is remote PDU'd, at least. (mac minis)

Our version of remote PDU is calling up for Smart Hands to turn around and tell us to place an order against a non-existent draw-down account and have to call over to the Fed side to get funding for them to get off their butts and then a week later they tell us they turned off the wrong system but they can't remember and is that a problem? Also they'll need more money if we want them to figure it out.

Wild EEPROM posted:How much pain are you willing to endure? The HP workstation series (Z440, etc) are also decent alternate options. They tend to sell for a bit less than the Dell or Lenovo options, probably due to being less popular on some of the DIY build sites, but they work just fine. Biggest downside to them is they tend not to have IPMI, so you'll need to manually set things up at least once. They also use a custom power cable like some of the Dell's, so same deal there ($20-$40 adapter) if you wanted to move the guts into your own case, but I've found mine to be reasonably quiet as-is.

They also use really odd mounting screws with built-in shock absorbers, some of which are nearly impossible to find and are often discarded by resellers. You can buy them online or 3D print your own, but it's a word of warning to potential buyers. I've got several HP workstations, and I've had to 3D print spacers for the drive cages to work properly. There are even 2 different ones for 2.5" drives, depending on the model of computer... I'm happy with the computers, but the screws are a pain in the rear end. My SSD in the Elitedesk 800 G2 SFF are just double-sided taped in place because I couldn't be bothered to dimension the second type of screw spacer. I've got an EliteDesk 800 G2 tower too, and it takes the same dumb system.

Mine didn't come with cages at all, so I used a 5-in-3 I had laying around instead  The level of effort that Dell/HP/etc go to to try to make reusing their stuff with anything even resembling normal industry-standard equipment is both wild and super obnoxious.

I for one would love a general purpose "IPMI" adapter even if it was just that, video capture, power, and USB, because while it's usually easy enough to spec a proper server platform in new builds it would be really nice to be able to at least have some kind of remote diagnostic ability I could add to home machines built from spare parts or existing servers at customer sites that were not specced with remote management or aren't really actual server hardware. Doing a bit of poking around I've found someone selling an adapter that claims to convert 1080p HDMI to a signal a Pi can accept on its camera input for $20, so I think I might order one of those and see how it goes. It'd obviously be more useful for a lot of server hardware if I could get VGA input on it, but my own home hardware has a desktop GPU installed so this will work for my needs.

With all this info coming out about the SMR drives, I've heard that the easystore drives (above 6GB) are still hopefully safe for the moment to use, correct? I've found that I'm needing a new external drive for the moment and if these are safe, I'll definitely grab one but wanted to make sure of that first.

Well, the source is some random guy on Youtube whose only contact information is a gmail address, but there are people on a few forums talking about having received parts from him so I figure I'll give it a shot as long as he takes paypal or something along those lines. Worst case I'm out $20. There's also a product on Alibaba for $36. It's the same chip as in the Auvidea design AFAIK. Apparently a normal Pi only has two lanes of CSI and thus can only capture 1080p at 25-30 FPS, but for purposes of a DIY external remote management box that's perfectly sufficient. A Compute Module has a full four lane interface.

WD is correct that, as the end user, the underlying technology isn't what should be driving our purchase. If they use something they dug out of an Aztec temple it doesn't matter as long as it meets the performance specifications. They try to deftly overlook the fact that they changed the performance specifications without telling anyone. There's probably some data sheet or small print somewhere that, if you compare it to pre-SMR drives, will show the performance differences. However, that's effectively "not telling anyone".

They just need to stop selling the drives full stop. Call them Greens, and scrap the entire Red lineup, and just move people to "Red Pro". I'd have never even expected SMR on a Blue drive, let alone Red. It's definitely something that seems like it should be in the Greens, the absolute lowest of the low, where you'd expect it.

The problem, of course, is that more than simple performance metrics matter for NAS applications of any sort--from a simple home 2-bay Synology all the way up to some of the crazies in this thread running legit disk shelves. "SMR drives can support normal light NAS workloads but cannot be used for rebuilding an array with because they choke and drop out of the array" makes them entirely useless as actual NAS drives, to the point that it might actually make more sense to use a Black or other non-SMR-of-any-type drive for NAS applications. If I wanted to use your drives as single non-RAID members I'd have loving left them in their external enclosures to begin with!

If you have a host motherboard that supports serial in the BIOS then you really just need a couple bucks worth of level converters for that and relays or transistors for the power/reset signals. A Pi 4 already supports USB OTG peripheral mode and can act as a USB keyboard/mouse, flash drive, etc. while running off of PoE. I have actually ordered a couple of those HDMI to SCI2 bridge boards this last week from Aliexpress. I am attempting to build a zero-U ip-KVM device using an R PI. I actually didn't know that the Pi4 could present it self as a Keyboard and mouse. My plan was was going to up an Arduino Micro Pro on top to be the HID device for the managed PC and communicate to it from the Pi using serial.
