UNder Heavy ⚙️ Development... The NAS that is now taking shape!
This is just a peak about what I have been doing lately with my NAS...
My own cooling modifications!
This aluminium heatsink on the ASPEED chip was a simple mod/cooling upgrade. And to make my point, it lowered the board temperature from 37ºC to 33ºC! And the sensor is quite distant away from the aluminium cooler I have added (this is a picture provided by ASRock for the thermistor location of the C2750/2550 boards):
Lot's of testing to make sure I will have the service I wish for. Therefore I need to be sure about tests like:
- Failing a disk does not crash controllers
- RAIDs using multiple controllers do not crash the RAID if one disk crash
- Moving disks between controllers (different ones) does not cause corruption
- Heated room (> 25C) can sustain heavy IO
So, for the last 2 days, I have played with my new 2x SAMSUNG 850 EVO and so far, I am pretty happy. I know they are overkill for XPEnology (because I am running IDE), but the final destination will not be the NAS anyway... so my thoughts about ordering them sooner, were to actually conduct some tests.
I have been doing all sort of tests in order to meet the objectives I have mentioned above. And so far, all perfect!
Caching... IOs is all I care!
Caching also makes a huge difference. Especially when running an Ethereum full node, some other wallets, and two 4GB VMs! All within 16GB of RAM. Look at these beauties...
I have too much work to do... it's impossible for me to have enough time to do this LIFE... but it's still something from which I learn a lot. So beware the next developments...
EDIT: 2017-09-21
After a couple of days working. Almost 79% hit rate... and today 94%! That's absolutely amazing. I have disabled "skip sequencial IO" option. So that might explain the increase on caching... I have now re-enabled to check if there is a big difference.
The next hardware upgrade (teasing)...
I am going to do some tests with M.2 devices. Two and four! This one is arriving soon and has a controller to support up to 4x M.2 B+M devices, two on each side of the card. With 4x PCIe lanes, that's 5Gbit per lane on PCIe 2.0, therefore, enough for each M.2 SSD.
RESTEEM if you wish to show others what you have learned... and,
