Adventures in Chia

This is actually using a number of parts I already had and making a second storage server. Here is the parts list for this build.  1 x Meshify 2 case (new) 1 x Seasonic 550w modular PSU 1 x Pair of extra drive trays (new) 1 x ASUS H370M motherboard 1 x Intel i3-8100 CPU 1 x Noctua NF-U9S CPU cooler 2 x 32GB DDR4-2666 ECC memory 1 x PCIe x1 SATA card (new) 1 x Intel X550 10GbE NIC 1 x 1TB Samsung M.2 SSD 7 x 8TB WD Red Pro drives 7 x SATA data cables 3 x SATA power cables

The first part of the upgrade was to the existing storage server. The existing server is in a Meshify 2 case and has 10 x 16TB HDD drives and a couple of SATA SSD's to use as log devices. The change was to bump the memory up to the maximum it supports (128GB). I tried around a year ago however the memory I got didn't work and the computer wouldn't even POST. This time using different memory modules it worked. While I was at it I disabled the log devices and removed the 2TB SATA SSD's. The log device is only used for writes. Seeing as the disks are full I don't write anything to the drives so there is no point in having a log device. I put a single 1TB SATA SSD in their place to use as a cache drive. I let the system run for a day so I could get some stats on how it was being used. It had a zero hit rate so I decided to disable it. On the subject of stats I seem to be getting around 75% hit rate on the memory cache (or ARC as its called under ZFS). A cache drive (or
