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

[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.

[Gibsalot]

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

[Gibsalot]

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

[haitch]

@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!

[altin.preniqi]

@haitch will it work as raid or not?

[vExact]

@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...

[haitch]

@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 ......

[haitch]

@haitch

128 GB of ECC RAM

192TB worth of these ....

Just need the disk controller and it'll be ready to start plotting & mining.

@haitch

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.

[haitch]

@rmbuan At my house for now - built two rather noisy 4U servers without thinking where they'd go. My wife is not too happy at the moment .... I could run it in the Colo I have my VM cluster, but for 4U it's be $200/month - which given the calculators estimate wouldn't be too bad ... might have to think about it. Will see how accurate the calc is first though.

[arihan]

Jealous looks really good.. Wish i could afford that many drives lol

[rmbuan]

@haitch Yeah my wife will freak out if I try to run any servers at home. Btw, if you ever have the time to do it can you share your parts list pcpartpicker.com it would be great in-case I get some spare budget.

[haitch]

@rmbuan I might post there when it's up and running, but it's:

Supermicro 4U 24 Bay X9QRi-F+ Quad Socket LGA 2011 Storage Chassis
4 * Intel Xeon E5-4650 8 Core/16 Thread CPU's
128GB RAM as 32 * 4GB ECC DDR3
LSI SAS Megaraid 9280 24i4e Array controller
24 * Western Digital HDD WD80EZZX 3.5in 8TB SATA 6GB/s 5400RPM 128MB Cache

It'll be using an SSD for the OS and swapfile, just haven't decided which one yet - possibly PCIe adapter M2 500GB
