It's an old Dell R410, with supplies DPS-500RB (12V only) and D480E-S0 (12/5/3.3V). If the second one died, the first one can't make the server still run, as there's no 5V or 3.3V!

It's an old Dell R410, with supplies DPS-500RB (12V only) and D480E-S0 (12/5/3.3V). If the second one died, the first one can't make the server still run, as there's no 5V or 3.3V!
Who cares, ya buck tooth limey.
from the manual:
" 4.1 Power Supplies " The R410 is powered by a non-redundant 480 W power supply (Dell P/N " F238K) and redundant 500 W power supply (Dell P/N F649J).
Seems to be some sort of marketing speak (by which I mean incompetent or intentional unthruths).
It seems the 500W unit is hotplugabble and can replaced from the back of the machine (like on machines with redundant power-supplies)
However the 480W is cabled to the main board and you need to open the case and unlug the cables to replace it.

That sounds likely.
So if the 500W failed, it would keep running, but if the 480W failed, presumably it would shut off since there's no longer any 3.3 or 5V? So unless I need more than 480W, the 500W supply is pointless, unless it makes the 480W last longer?
It would probably quit in both cases, else they would have built it with two 480W mixed-voltage powersupplies.
the 500W 12V only supply is probably used in some other chassis, in pairs, as a redundant powersupply, just the marketing guy is ignoring the the fact that in this application (Dell R410) it is not redundant.

Oh well, I have an extra supply now which I'll convert for GPUs.

Are you building a new computer for yourself?

Yes, a 24 core Xeon system. It will run the Rosetta Coronavirus researc= h program, and when that's done, something else in biology or physics.
In hindsight, it would have been cheaper to buy a crap version of the se= rver and upgrade a few parts. I've had to get some difficult to find br= ackets and adapters, like these:
That's a very noble thing to be doing. THANK YOU.
I'll have a study here and see what I could do personally to help:-
I was already doing it for fun and to help out astrophysics projects, I added Rosetta to the mix when the virus appeared. You can set up Boinc with as many projects as you wish and alter the priority of each.
It's a pity these projects don't hand out money (to at least cover the cost of electricity), then I think they'd get 10 times as many people doing it. They already have a brilliant system so you can see how much work you've done, and if you're doing better than others, so it would be easy to apply a small amount of money to that.
I believe the program will run on any CPU under Windows, MacOS, or Linux. If you have a good graphics card, you should go for Folding at home instead, as it can use that too.
Even mobile phones running android can run Rosetta. Not sure what you can run on Iphones.

Be sure to ask BD what his configuration/hardware is on the machine he sets it up on. He loves technical stuff. []'s

I've downloaded BOINC and installed it on my old iMac.
I chose Rosetta@home but I'm not certain what further action I should take. How can I tell if my machine is being used?
How old is your iMac?
There's a screensaver; you can watch it work.

If your old iMac is too old OS X, folding@home will allow 10.7 on Intel 64.
folding@home is actually a bigger project *

The Boinc interface is a piece of shit. I installed "Boinctasks" (in addition to, not instead of Boinc) which shows everything nicely in full colour and better organized. It also lets you monitor more than one computer on one screen. Not sure if it runs on Macs.
But you should see something like this in the Boinc manager - this is mine in Windows on one of my machines:

h 2 ,I would use that if Boinc had nothing useful for me to do, but I've been= with Boinc since it started a couple of decades ago. Nicer to have all= the projects in one place.
Does folding at home do biology research on graphics cards? Boinc only = has physics on the graphics cards.

Thanks, Mike. I'm watching right now! :-)
Can you see in Boinc what speed it says about your CPU? Tools menu, run CPU benchmarks. Then go to tools, event log. I get this on one of mine:
Mon, 27/4/2020 08:16:42 PM | | Number of CPUs: 6 Mon, 27/4/2020 08:16:42 PM | | 5069 floating point MIPS (Whetstone) per CPU Mon, 27/4/2020 08:16:42 PM | | 14441 integer MIPS (Dhrystone) per CPU
I'm wondering if that wastes computing power that could be doing the calculations faster.
