Pennywise 2 - Work in progress .......
-
@haitch Do you know how much nonces per min that stupidity amount of CPU will draw? LOL
With 2000€ I could get a monster in here but with just 2 CPUs (provably i7's, not Xeon's) and with 64Gb RAM but this monster would be able to connect around 1Pb splitted by SATA's and USB's but without NAS... With NAS, provably something like 4Pb xDOh if I had money to do that I would be a happy man LOL
-
drooling
-
@darindarin Yeah LOL
A 4Pb farm in one PC would cost something like 180k € and would ROI in 5-7 months
-
@gpedro Not exactly, but my guess is "A lot". The 40 thread Pennywise can do around 40,000 nonce/min , so, based on cores/threads/clocks my best guess would be around 96,000
Edit: An the theoretical storage that can be attached to it is simply stupid - back of envelope calcs says about 7PB.
-
@haitch So around 1Tb-1.5Tb per hour... That seems pretty damn good LOL
-
@gpedro Somewhere around there. The SAS controller has 6 channels, with 4 drives per channel, so the plan is to plot 6 drives at a time, one on each channel. Will report the actual plotting speeds when it's complete.
I upgraded the controller on Pennywise - from SATA2 to SAS2/SATA3. Same brand, but the arrays are not compatible - replotting Pennywise from scratch, but faster.
-
@gpedro I calc'd I could get it to 1.6PB for $45K, and ROI in under a year
-
@haitch I wish I could do the same hahaha
-
@gpedro I'm contemplating whether I want to expand it via my own funds, or make it an asset. As an asset it could expand rapidly and become a huge monster quickly, assuming the shares sell, but torn over whether another mining asset would sell or do I just want to keep it all for myself.
-
@haitch i been scoping out a few 4U units on Ebay saw several HP proliant DL580 G7's for a decent price. also found a supermicro 4U 36bay unit for only 450$ but it's only the 16 core AMD one not the xeon one
also the 36 bay unit will not detect HDD's larger than 2TB,
-
@Gibsalot I have a DL580 G1 - quad AMD processors, but only 2.5" drives. But also a ton of PCIe slots, so could massively expand it. The Pennywise 2 chassis + mobo was around $850 on eBay, the CPU's, $100/each, and 128GB RAM for around $300. If you can find the right chassis, it's not hard to build a monster system through eBay - the key is the chassis + mobo. Combo deals are normally the best. Check out the For Sale for Mr. Rackables.
Edit: And yeah, always check the backplane and controller - you need SAS2, otherwise you'll be stuck with 2TB drives.
-
i found the chassis your using for 350$ , not bad for 24 bay , i figure i have two block release's of my asset and ill need a new rig to add drives , as this one will be maxed as long as i can get decent HDD prices. starting the process of scoping out a large rig and seeing what kind of prices ill be looking at , next rig will be a dedicated burst mining rig
-
if that older supermicro 36bay amd cpu rig would support larger than 2TB drives id snatch it up in a second drop in a GPU and some USB3.0 exp cards
-
@Gibsalot To be able to use > 2TB drives you need a SAS2 backplane. Triple Check the backplane on any chassis, if it's SAS1, avoid.
-
@haitch OMG!
-
@haitch will it work as raid or not?
-
@haitch I am actually thinking in getting one of those in the near future. Problem is that in my flat do not have so much space really, and I have to share the studio/office space with my GF :) Tose supermicro systems look to be the ideal ones indeed...
-
@altin.preniqi It could be RAID'd, but I'm not individual drives.
@vExact Yeah, know about the space issue, I now have two 4 U servers and didn't think about where they were going to go ......
-
128 GB of ECC RAM
192TB worth of these ....
Just need the disk controller and it'll be ready to start plotting & mining.
-
Wow very nice setup you got there.. Where are you running this in a colo? I wish I can plug this kind of equipment on our DR site hehe
For my work, I should stop buying EqualLogic and build our own NAS system. 192TB storage vs 40TB for 30k CAD!!! Although, my higher ups are afraid of no 24/7 warranty so it might be a hurdle.
