Simple(?) question:
With a TS-473A, I want both SSD Caching AND TPU support.
- will TPUs work on the M.2 expansion cards (Transparently)?
- if a QM2-2P-344A is utilized - is it better to put the SSD drives or the TPUs on the M.2 expansion card?
- Can multiple TPUs be used together on the QM2-2P-344A card?
- will the QM2-2P-244A be sufficient for the TPUs from s/w Compatibility?
a) TPU are single type 2 channels
Thanks !

Please forget about cache on QTS devices (destaging is broken)
You can switch to QuTS if you want better (and working) cache
I can testify to this. I bought two 1tb ssd’s (raid1) to cache a 19tb raid5 on a TVS-h1288x. It slowed to a crawl (QTS).

Well - Never mind - the question revealed that the the TS-473A M.2 slots are Gen3x1, so putting an SSD in there is a bad move - they get the TPU.
In the meantime - now I have to figure out how to move the OS/Apps stuff off the SSD on one of the M.2s…
