The full writeup of this upgrade can be found
on my wiki. I sought to remedy some of
the errors I'd identified in my
Schwarzgerät III build several months earlier.
Primary among these changes was inverting the PSU-side XFLOW 240. The PWM D5 in my Quantum Kinetic FLT240 had died; I replaced it with the Vario from my Monsoon, which was removed entirely. I added an EKWB Dual XTOP with two D5 pumps, along with a custom-designed brace. I designed and printed cable baskets for the bottom of the motherboard side, which both cleaned that area up, and provided large reflectors for the LEDs running along the motherboard side's XFLOW. It's almost as if I added two large RGB panels.
A new 4-disk bay on the motherboard side gives me 16 total 3.5" 18TB disks, for 288TB of ferromagnetic storage. These are arranged in a stripe of two octodisk ZFS raid2zs; in the Old English, this was known as a RAID60. Four parity disks mean 216TB of usable space, almost a quarter-petabyte. 6TB of fast NVMe SSD are used for day-to-day active storage, though with 256GB of DDR4, most things live comfortably in cache.
