- those discs (hgst deskstar 8tb) are all connected to a 24 port sas hba.
Do you find the speed difference between SAS/SATA makes any difference for Burst Mining? And what about the Hard-Drive Cache?
(https://www.broadcom.com/products/storage/host-bus-adapters/sas-9305-24i).
Only see 12x data slots on that [PCIe 8x] DIC. Do they all double up? Presume you also have a dedicated (rack) server case to store all those (24) drives. Any pictures?
SAS or SATA makes no difference in this case, because i use SATA drives and SAS->SATA adapter cables.
There are 6 SAS connectors on the broadcom and each connector has 4* SAS3 connections. My "professional" rack case is selfmade :D will post pictures soon
i tested the maximum speeds of the hba by copying from my first 12 hdds to the second set of 12 hdds which resulted in about 200mb/s per drive -> 2,4gb/s total read and write with all hdds connected to the same hba.
I guess that's why you need Server CPUs. What's the MoBo & Psu?
You can use the same PCIe adapter in every mobo with a PCIe x8 slot. It does not need too much gpu power. Main reason to go for xeons is, that i get 2*40 PCIe lanes which are quite useful when i use that server as a workstation/gaming pc when mining is no longer profitable.
- I'm currently using ntfs
Is there a possible, superior option that you're considering?
EXT4 could be useful when switching from windows to linux.
those plots were just some tests to find the bottleneck that limits my plotting.> you dont need to connect the gpus using sli, there are just minor differences. those gpus should be able to put lots of data to the drives (200k nonce / min = 50gb / min = 20 min/tb). But there is a bottleneck (mb in the plotter, mb in windows) that i'm still trying to find.
Fortunately, each HDD only has to be plotted once or twice. So, not that burdensome considering the projected working life of the Drives.
Yeah, thats a big plus. But i still needed about 120h to plot only 12 drives (96tb) and this server might get upgraded to more than a pb soon :)
