Im new to vSan and am doing this in my Lab as a learning experience.

I currently have a FreeNas environment with the following specs within FreeNas and get about 1 to 1.1 GB's in read and writes.
- 500GB SSD's in mirror Fdev x8
- intel Optane as log

for vSan, I have the following across 3 hosts and get about 1.6 read and 300ish write.
- 1x NVME 256GB (with high performance turned on) as cache
- 3x 500GB Sata drives

Tried doing a capacity that exceeds the cache devices?

Not sure I follow the logic here. Granted most servers come with a 1TB NVME as cache on the host with storage SSD’s at 960, but the lower cache (log) size in freenas appears to work out well.
