Nice numbers! Are those cards they're installed on supported on the BOTTOM of the chassis? If so I'd fab up a simple AL latch and call it good, for home rack at-least...
I'd also re-run that test with more GB so you're not playing in cache/rAM only on those drives... figure out how much RAM cache they have and then * # of cards and then go 2GB above that and re-test
That will be interesting to see if it changes much, it may even go up... testing 1GB spread over a # of cards isn't enough I don't think to really put them into 'real' test
Did you order your E5-2620 v3s ?
I have a pair I'm going to test replacing with QS CPU and then sell them if the QS work (Ill run QS) in the Intel Motherboard.
I ran it @4GB earlier without much change.. how can I verify what it takes to out run the ram cache? Currently has 128GB ram installed.
Looking at the settings in the device manager write caching in NOT enabled...
On a different note, I've created a problem with the switch fans.. while converting the Sunon fans to the Noctua's I made the change one module at a time, checked the switch via terminal and the led's on back, and each time it was happy. What I did not do was reboot the switch....
Now having rebooted, I'm locked out due to "fan failure". I replaced 6x 4 wire PWM fans with 6x 3 wire non PWM fans... because it didn't lock me out as each group was swapped, I made the poor assumption that it would let me run like that as long as temps stayed in check.
Apparently it will not.
Does anyone have a technical paper explaining exactly how PMW works? I have to assume that the switch is determining fan function based on the PWM signal... so what's the best way to feed it false info? Is it simply a voltage signal (I'm assuming not.. hence the "pulse" in PWM".
I'd rather go back to AOL dialup than listen to the Sunon fans run 17K RPM.
Also considered:
-water cooling the damn thing (complicated/overkill/cool & silent)
-building/buying a new chassis that allows for larger fans and transplanting the internals (also a pita, current internals are well engineered with ducting/flow control... hate to tear that up).
-building a 2U cover for the existing base chassis... would have to rebuild internal ducting, but not too bad.
-Building a plug an play hot swap adapter for each of the three fan modules allowing for a larger fan. This appeals to my inner engineer and is probably the cleanest/coolest option... would take some fab work to do it right. I can get one of our packagers to cut it out if I put together the drawings, but still not a get it tonight option.
-Cutting a hole in the top cover just in front of the existing fan modules and mounting two PWM Noctua industrial 120mm 3K RPM fans... This is easy and definitely a get it done immediately option... but it feels akin to putting "spinners" on a 911 Turbo... such a nice switch; hate to rice it out. This would also be pulling intake air from the top of the rack which is not ideal... I suppose I could add some ducting to pull from the front of the rack, but now we've got spinners, neon under chassis lighting, and a wing out back
