I'm curious - why is this system so expensive? It seems like equivalent systems are far cheaper. https://www.ebay.com/itm/145624272854 Thanks!

new stuff coming =)

Hey Mike, Thanks for your wonderful post. I just wanted to share my experience with memory errors on EPYC boards- in the vast majority of cases, it's been not enough torque on the CPU (some boards just need more torque) or using a torque tool that is inaccurate (they all have +/- error) or has...

Any idea on power on hours? if it's anything like the picture it seems they're no older than a year or so. If so, great find!

We could run the numbers (I admit this is a bit dubious/debatable), but let's say you go for 24x3.2TB that's roughly 77TB usable with an average idle of 5w per drive, 120w idle + SAS expanders, p/s, fans, etc. You're looking at around 180-220w idle plus cost of removing said heat. Or you could...

If you're worried about endurance you can under provision the drive(s).

New 15.36TB Gen4's non-vendor drives are going for under $900 on eBay: https://www.ebay.com/itm/155653870794 https://www.ebay.com/itm/295419579013 https://www.ebay.com/itm/155751036696 Dell 15.36 TB SSD x4 | eBay (4x for $2800 -used) 2 x Micron 9300 Pro 15.36TB U.2 NVMe PCIe SSD Drive Model...

An idle of 12-15w is a bit insane for a 15.36TB drive @ gen3 speed... That means you need considerable airflow (aka even more idle watts) to keep these drives operational. While low cost, electricity prices will add up. Consider: 12w * 24 hrs * 31 days ~ 9kw At .30c a kw (maybe more or less...

That's a 3rd gen 205w cpu, boards are going to be a little expensive.

It all depends on what is under the hood - If you run 1 cpu (L & V4 version), only necessary ram (ram uses 1-3w per stick), no sas (remove perc controller and just run the backplane straight to the m/b- sata only), low fan speed, 1 p/s- what else is there? A bridge chip, cpu, bmc and maybe a...

I'd say a r520 or r530 then- since all your drives are SATA you don't need power hungry sas controllers. Run 1x e5-26xxL v3/v4 series cpu (you have the option to expand later since r5x series are dual processors capable but are usually fitted with just 1). 1 p/s and you're golden. Plus you have...

I see. EU prices are typically higher but you guys get cool warranty right? On the power end, there are many ways to get that idle power down if that's your concern. 730's have dual cpus and are typically using a 12-15w sas controller (perc) and a 5-7w sas expander (do you need sas?). You can...

Cross posting b/c this topic tends to come up a lot... Perhaps buy a real server? You can easily get a Dell rx20 (i.e., 320, 330, 620, 720) /w free shipping for dirt cheap these days. Check eBay. V3 xeons (i.e., e5-2640 v3- $6 on ebay) and DDR3 memory are dirt cheap or you can go with the rx30...
