Verified via lsblk TRAN column and dmesg that tsys6/7 local-lvm is
backed by WD My Passport portable HDDs on USB 2.0 (~30 MB/s), not
internal SATA/SAS as previously assumed. Both R610 and R620 only have
EHCI controllers -- no USB 3.0/xHCI. tsys7 has 5 empty SATA ports but
no drives installed; tsys6's SAS controller is disabled in BIOS.
Corrected all wnode recommendations: tsys6/7 stay on NFS (faster than
their USB 2.0 local-lvm). Only tsys3/5/9/2 have local storage suitable
for VM boot disks.
Also discovered tsys3 boots from Samsung PM961 NVMe 512GB (previously
documented as HDD). Its 349 GB local-lvm is the fastest existing local
storage in the fleet.
Updated speed tier table, wnode placement tables, storage distribution
matrices, migration plan, and caching strategy across PROJECT.md and
K8S.md.
