Pennywise 2 - Work in progress .......

[haitch]

Chassis and CPU's arrived today :)

[dfinc]

@haitch Nice! How many tb are you planning to put in?

[gpedro]

@haitch What am I looking in the 2nd and 3rd images?

[haitch]

@dfinc 192TB to start with. That's already ordered and in transit. Then a 360TB expansion. And then maybe a second and third expansion ......

@gpedro Pic 2) Motherboard - Quad Xeons, will have 32 Cores/64 threads, 128GB RAM. Pic 3) The CPU's - 4 Xeon E5-4650's.

[gpedro]

@haitch Shit... How much did you spend in that PC without the NAS? That would cost me my eyeballs in here LOL

I mean, I think I would not even be able to buy that Mobo in my country lol, last I checked the max I could get would be 2 CPU per Mobo and it was something like 350€-400€ just for the Mobo...

[darindarin]

Jebus dude.. haha

[DFWplay]

@haitch SAS or SATA drives? HP or Dell?

[haitch]

@gpedro Chassis, mobo, CPU's, RAM, dual/redundant Power Supplies ...... $US2,000, 192TB in WD 8TB Drives - $4,200. Estimated ROI is 7 Months.

@darindarin Go big or go home, right? ;-)

[haitch]

@DFWplay System is a Supermicro, drives are WD Sata, hooked up to a 24 port SAS 2 controller.

[gpedro]

@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 xD

Oh if I had money to do that I would be a happy man LOL

[darindarin]

drooling

[gpedro]

@darindarin Yeah LOL
A 4Pb farm in one PC would cost something like 180k € and would ROI in 5-7 months

[haitch]

@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.

[gpedro]

@haitch So around 1Tb-1.5Tb per hour... That seems pretty damn good LOL

[haitch]

@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.

[haitch]

@gpedro I calc'd I could get it to 1.6PB for $45K, and ROI in under a year

[gpedro]

@haitch I wish I could do the same hahaha

[haitch]

@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,

[haitch]

@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.
