Any insight or advice is appreciated.
Looking to upgrade my 45drives server CPU/RAM and motherboard for 2x 25GbE or 100GbE SMB. Array will be 6x stripes of 7drive RaidZ2 plus 3x hot spares (45 drives total). Home lab use cases; primary performance drivers:
1) Individual workstation clients that need to move large quantities of data across Ethernet/multithreaded SMB, but typically one client at a time.
2) Virtualized Linux desktop w/GPU pass through for some local HPC tasking.
Besides the typical SMB loves high clock speeds, I can’t find data for comparison of these CPUs. All systems would have 8x 64GB ECC RDIMMS.
Options
1) Threadripper Pro 5975WX 32c@280W / 4die w/128MB L3 - outright clocks and cores
2) Epyc Milan Freq. 74F3 24c@240W / 8die w/256MB L3 - moderate clocks w/medium cache
3) Epyc Milan-X 7473X 24c@280W (cTDP up for 280W) / 8die w/768MB L3 - lower clocks w/large cache
The 74F3 has a great all core turbo with much less cache pressure and no 4die Infinity-fabric memory bandwidth limitations like the TRP; but hard to beat more cores and clocks. I can’t find data on how Milan-X all core behaves with the increased cTDP…probably not too far behind the 74F3?
Thanks!
