hi all!!!
no experience here, to a mash up mining rig, for burst and ETH??
i explain better.
I want to buy a 7 PCIe mother board with 6 RX470 Nitro 4 gb and on the seventh PCIe plug an adaptec SATA controller for 8 SATA drivers...
Do you think my PCIe bus will support all this traffic???
If yes i can mine with the same RIG, BURST and ETH.
I have been running a mining rig since 8/2014 on a fat 32c machine with 6x PCIe (Gen2) slots.
Never had any io-bottleneck, and this is a very busy machine.
I/O:
To mine 1 TB you have to read 1TB/4096=256 MB.
If you want to finish in under 60 seconds, that is 4,5 MB/s of bandwith for one minute every 4 minutes.
Now lets say you connect 8x 8TB disks to your rig, that would mean 286 MB/s of bandwith for one minute every 4 minutes.
I/O wise this is not even saturating a single PCIe (Gen3, ~1 GB/s) lane, and even a single SSD yields about 500 MB/s.
compute:
If you have a AVX2-capable CPU, the computing takes up just seconds per block (4 minute block time).
I just ran a test; on my 2.1 GHz E5 combing 60 TiB takes 140 cpu-seconds (divisable by number of cores that you can spare for this).
The speed increase is (nearly) linear w/regard to clock speed, so you might easily get away with 2 cores @ 2.5 GHz for 64 TB in under 60 seconds.
Using a SSE4-only CPU roughly doubles the CPU time, using (part of) a GPU (via opencl, support included in the java-wallet) is faster by
a factor of 2-10, depending on your GPU.
plotting:
I did most of my plotting on several (now historic) 280x, yield was 170 MB/s per GPU.
To put this into perspective, the AVX2 code on 2.1 GHz gave me 3.8 MB/s per core. SSE4 is about half of that.
hint: If you're going the manual route (like real men do), use large files (500+ GB), plot to a temporary target,
optimize plotfiles from temporary to the final disk. I have no idea about the AIO package or Windows in general.
just my 0.02.
