Okay I seem stable on the panda and two other rigs.
I am going to move more rigs here soon.
So what is the limit of rigs? I would stay with 8-15 rigs.
I also Need to decide if I need SRR all rigs are in my home So a rest is pretty easy. But I do vacation.
My pdu can be turned on and off via the internet. So I may not need SRR.
Hi Phil,
What is the cost & benefit comparison between a switched PDU like APC vs SRR?
SRR being a cost effective with standard parts vs "professional" systems like APC, Triplite etc.
I believe SRR is a "few hundred dollar" solution (with mining features) versus "a few thousand dollar" solution (with data centre features?) out there.
Thanks
I have APC PDUs. 1 PDU alone is already setting you back $70-110 shipped used from Ebay. You will need to get the serial cable to set it up properly for IP address, etc.
Here's the pro and con of each solution
APC
Pro
- Simple to use and no wiring.
- You can setup Port forwarding to connect to home machine or use Teamviewer to manage turning port on and off
- You need a PDU anyways, so the cost premium may not be too high. This is also a very nice PDU as it can be managed via web browser and have amperage LCD
- Tons of power connection ports
Con
- Each PDU is max at 30 AMP but recommended 80% usage which is 24 AMP or about 4-6 rigs
- Cost to manage more than 4-6 rigs will be be based on how many PDUs you need, so it can add up a lot if you were using cheap $15-30 PDU before thinking of getting APC. However it's a moot point if you're ready to spend on PDU at this price anyways.
- You may need to buy a serial cable to setup the PDU as the document to use arp -s IP address mac address may not work
- Setup is less friendly then SRR and less technical people may end up not bother setting it up and using it as a Dumb PDU instead
- Bulky PDU vs other PDUs that is easier to tie to your regular shelves rack or mount on rear of server RACK. This one is very FAT and deep so it normally sit on the floor or is mounted horizontally in your server RACK. Each 42U server rack needs at least 2 PDUs and 2 of these in a rack will eat up at least 4U of valuable space.
SRR
Pro
- Starts at $100 to manage up to 8 Rigs. This is Pro and Con
- Agent for auto reboot if rig freeze vs manual monitoring for APC. Very important for large farms
- Price is much more competitive as you get above 8 Rigs especially over 16 rigs
- Can scale up to 64 devices. The higher the device count, the cheaper it gets per rig
- Web server to manage is good and differentiate this product from other similar offering that is less intuitive
Con
- Additional wirings that need to be run from the SRR to the different rigs
- Easy to wire for open air racks but for server rack solution it may be trickier as you do have another wire to remember to disconnect when removing and servicing the rig
- Price per rig makes the most sense for 4 rig solutions + but still competitive vs other similar solutions
Tytanick will be sending me 1 to evaluate and demo. I can do a full review on all the different configs as my Farm consist of all the popular RIG types, frames and layout
@ Tytanick / admin - What is the ETA for the update that will show total hash per rig and total hash for all the rigs? I think that is a much needed feature when you have many rigs to catch issues / discrepancies quicker.
