Quick update Nov 2023
Chia 2.1.1 released. All disks are full of uncompressed plots. I need to get a Nvidia GPU with 8GB (or more) vRAM and replot to get some compressed plots. Farm currently consists of: Primary Storage server (Ryzen 5600X, 128GB RAM, 10 x 16TB HDD in raidz2). Has 1060 plots. Secondary storage server (Core i3-8100U, 64GB RAM, 7 x 8TB HDD in raidz1). Has 397 plots. Pi storage server #1 (Pi4, 4GB RAM, 2 x 16TB HDD in btrfs single mode). Has 290 plots. Pi storage server #2 (Pi4, 4GB RAM, 2 x 16TB HDD in btrfs single mode). Has 290 plots. That gives 2037 plots taking 201.6TiB. I also have a plotting machine that is a full node and mainly for plotting. It doesn't have a discreet GPU at the moment. I could add some more USB connected HDD to the Pi's fairly easily but have to organise another power board for all the power adapters. I have some 10TB Seagate Expansion drives and a USB 3 hub available.
