Finally, the separate box of POWER9 upgrades appears. These are for the dual socket 144 thread Talos II here at home (the LC-922 are in colo). Relocation has turned up a lot of missing hardware, very pleased about this turn of events.
So, the long lost box contains:
- 4x Samsung 883-DCT 2TB SSDs for local storage ZFS pool (with 2x Optane NVMe cache)
- 3x PM863a 240GB SSDs for the OS
- always more RAM
- an OcuLink 4x to U.2 cable w/ Optane drive floating around somewhere
- Mellanox 50GbE QSFP28 NIC for RDMA fun@dexter finally, we can continue the project with appropriate hardware

💻 Hello Old Friend, Talos II 💻
This was my first IBM POWER9 system, acquired in 2020 and built for home/desk use. Dual socket SMT4 Sforza, 144 threads, 256-512GB RAM, various storage/net/accelerators over the years. [1]
As expected, I fell in love and acquired four IBM Power System L922-2U [2], which are presently in the colo awaiting network rebuild (remote hands this time).
The Talos II has served a variety of purposes, with most of its time running FreeBSD PPC64le (&a bit of PPC64be for fun). Sometimes also Linux, back when I was tearing into qemu code for compiler optimization hypothesis testing, RTX GPU passthrough, +validating assumptions about qemu on P9/le handling amd64 & arm64 emulation.
So, out of storage! Into the rack! New user accounts! But first it needs updated OS drives (the 3x 64GB SATADOM in Raid-Z1 need to be repurposed), and a NIC (25G-DP CX-5 or X710-DA4).

For now, #QEMU supports only 3 #CPU architectures ( #AMD, #IBM #POWER9 #POWER10 and IBM #S390x), for Intel and other(?) architectures, support doesn't exist yet - one can find it in QEMU #documentation about Confidential Guest Support https://stackoverflow.com/a/79195057/499698

#darktable runs on my #power9 machine natively now! woohoo!

Checking on shipments before starting the workday to see if the newly acquired (fourth) LC922 is transiting to the colo… and yes, it's true #iLoveIBM!
Still pending OS storage decisions before supply chain:
- remain standardized on dual S4510 / PM863a
- alt standard w/ dual SATADOM for EFI boot handoff to dual NVMe
- introduced new standard of dual 2TB P3608 Optanes
- disregard OS drives and use iSCSI boot
- other ideas… 🙇🏼♀️
