My only real complaint is the Molex connectors on the fans instead of regular 4-pin (aka bloody knuckles when building), but this can be easily remedied with aftermarket fans.

with one of these for 12 drives in the front, you can get to 12 drives for $130, with 2 of these you can get to 16 drives for $150 with room for a full ATX motherboard (really tight) or micro ATX board.

The Chenbro

The legendary Chenbro is a 1U server that holds 12 3.5in HDDs. Can be found on eBay for $100-150, with compute included for an integrated farmer.

These are 101.3GiB, 108GB or 106,000,000kB (stupid Windows displaying in kilobytes)

Step 5 – Farming

To start farming, you need the full node to be synced. Remember this takes a day or so. When the database is fully synced and you have the latest and fully validated copy of the blockchain, you will see it say “Synced”

Click on the farming tab, you should see your plots show up here. If they are not, click add directory and find your HDD where the plots are located.
If you are farming correctly, they should show up green like this!

If you selected self-pool above, now you will want to join a pool so you can actually get some farming rewards.

This varies between consumer and data center grade HDDs. To do this requires adequate airflow and fans in the farming case, and also monitoring with SMART.

  • Maintain a reliable farmer. We do not want the farming system to go down. We do not want any single failed component on the farmer to take the whole system down.
    We do not want farming downtime (this is lost time and XCH farming)
  • Host connectivity. In general, farming will be either remotely connected through the network (NAS, network-attached storage) or directly attached to the farmer (DAS, direct attach storage)
  • Redundancy & RAID. The majority of storage systems are designed with durable storage in mind, and contain redundancy with RAID, erasure code, mirroring, or backups.

    EX:harvester: chia_ssl_ca: crt: config/ssl/ca/chia_ca.crt key: config/ssl/ca/chia_ca.key farmer_peer: host: Main.Machine.IP port: 8447

    For example, this section would look like:

    harvester: chia_ssl_ca: crt: config/ssl/ca/chia_ca.crt key: config/ssl/ca/chia_ca.key farmer_peer: host: 192.168.1.23 port: 8447

    1. Launch the harvester by running CLI chia start harvester -r and you should see a new connection on your main machine in your INFO level logs.
    2. To stop the harvester, you run CLI chia stop harvester

    Warning:

    You cannot copy the entire config/ssl directory from one machine to another. Each harvester must have a different set of TLS certificates for your main machine to recognize it as different harvesters.

    How to farm chia on multiple computers

    Unintended bugs can occur, including harvesters failing to work properly when the same certificates are shared among different machines.

    Security Concern:

    Since beta27, the CA files are copied to each harvester, as the daemon currently needs it to startup correctly. This is not ideal, and a new way to distribute certificates will be implemented in a subsequent release post mainnet launch. Please be careful when running your harvester that is accessible from the open internet.

    Note:

    The GUI show harvester plots after running some minutes.

    The easiest way to see if it’s working is to go the “Farm” tab, and check the “Last Attempted Proofs” pane.

    How to farm chia network

    You’re going to show your harvester these files temporarily and then you can delete the /ca directory in your temp folder.

    1. Make sure your main machines IP address on port 8447 is accessible by your harvester machines
    2. Shut down all chia daemon processes with chia stop all -d
    3. Make a backup of any settings in your harvester
    4. Run chia init -c [directory] on your harvester, where [directory] is the copy of your main machine /ca directory that you put in a temp folder. This command creates a new certificate signed by your main machine’s CA.
    5. Open the ~/.chia/mainnet/config/config.yaml file in each harvester, and enter your main machine’s IP address in the remote harvester‘s farmer_peer section (NOT full_node).

    How to farm chia on raspberry pi

    For this guide, we will be focusing on setting Chia up for a headless setup. This means all you need is SSH access to your device.

    Equipment

    Below is the list of equipment we used when setting up Chia on our Raspberry Pi.

    • Raspberry Pi 4
    • Micro SD Card
    • Power Supply
    • Ethernet Cable or Wi-Fi
    • External Hard Drive or USB Drive

    Optional

    • Raspberry Pi Case
    • USB Keyboard
    • USB Mouse

    We tested running the Chia blockchain on a Raspberry Pi 400 using the 64-Bit version of Raspberry PI OS.

    Preparing your Raspberry Pi for Chia

    Preparing your Raspberry Pi to act as a Chia farmer is a relatively straightforward process.

    There is one big caveat though, we require a 64-bit operating system. This means you will be limited to using a Raspberry Pi 3 or newer.

    How to farm chia forks

    While far too detailed for this post, SAS is designed for scalability with many hosts, many targets (drives), and flexible infrastructure (cascading, expansion, etc.). You can access many drives through a JBOD through a single SAS cable. SAS infrastructure, like HBA (host bus adapters) and JBODs are backwards compatible with SATA drives.

    This is the reason you can buy a SAS enclosure or JBOD, and natively put SATA HDDs in it! SAS also happens to be a lot faster than SATA, with 12Gbps and 24Gbps protocols (vs SATA at 6Gbps) and can tunnel 4 SAS lanes over a single cable.

    45 drives (4U) – The cult of the SM45

    Known in the farming channel as the SM45, this is a 45 bay 4U JBOD from Supermicro. This was a very popular JBOD and is easy to find replacement drive caddies, power supplies, fans, and other parts.

    China coin farm

    A JBOD does not contain any compute, and needs to be attached to another host. With the SM45 you will need an HBA like the LSI 9200 or 9207 ($20-30 on eBay) and a set of miniSAS external cables (SFF-8088). At 45 drives, 75W idle power, and a used cost of $200-300 (before shipping), this is one of the most attractive options for mid-level farmers.
    Screwing in the hard drives to the drive caddies (sometimes called sleds or carriers) is a Chia farmer’s right of passage.

    90 drives (4U)

    The SM90, or SuperChassis 946ED-R2KJBOD houses 90 drives in a 4U chassis. All the drives can be accessed with a single miniSAS HD external cable (SFF-8644) and an LSI 9300-8e HBA. This has 4 power supplies that are fully redundant, two SAS modules with independent paths to a host, and amazing cooling (warning VERY LOUD).

    How to farm chia reddit

    You may have been like me, started your Chia Plotting and Farming on the first machine you had available. Then, after some time, you figure that you want another computer to stay on 24/7. How do you do that? Do you need to install Chia all over again and wait for the dreaded Sync that can take hours, if not, days? Its actually really easy to move your farm to another Windows PC.

    I am unsure if this will work moving to/from Linux or Mac, but continue reading to possibly identify potential time savers.

    1. First, get your second machine setup. Take the time now to reformat the machine with Windows 10 if you want. Install all the Windows updates. Update the BIOS of the machine. Do all the maintenance things so that you don’t have to do it later.
    2. Next, install the chia software.

    How to farm chia on linux

    cd ~/chia-blockchain/

    2. Now, run the following command on your Raspberry Pi to activate the virtual environment.

    We need to be in this environment to run the Chia commands.

    . ./activate

    3. As we are now in the virtual environment, we can finally make some Chia calls to check the status of your farm.

    The first command we are going to use will give you a status update of the Chia node running on your Raspberry Pi.

    This command will tell you the status of the blockchain, the estimated network space, and other information, such as what nodes you are currently connected to.

    chia show -s -c

    In the screenshot below, you can see that our node is still currently syncing with the rest of the Chia mainnet.

    4. We can also check on the status of the Chia plots that our Raspberry Pi is farming.

    Those who do plot larger are either doing them to show off (and we encourage this for fun) or to optimally fill the open space on a specific drive. A k32 will take up 101.3 GiB of space once completed but will need a total of 239 GiB of temporary space as it is being created. A single k32 plotting process never needs more than 239 GiB of space.

    One needs to be careful here as 239 gibibytes uses 1024 as its divisor where GB or gigabytes uses 1000 as the divisor. That means you will need 256.6 GB of temporary space and the final plot file will take 108.8 GB. A k32 plot can be done by one expert we know in just under 4 hours, but most experts are creating plots in 5 hours and most folks average around 9-12 hours.

    Creating a plot is a process that will take RAM, CPU cycles, IO to your disks and it will use them differently in each of the four phases of plotting.
