How much does Intel® Cache Acceleration for Linux cost?

Question

caching

Greetings.
I'm looking for a solution to implement caching on the server.
Learned about this Intel® Cache Acceleration for Linux software.
Does anyone know how much it costs?

Answer 1

$665

Answer 2

for windows, I still understand, but why buy ssd caching for linux? Are there any objective reasons and tests showing that the same bcache/dm-cache/enhanceIO/flashcache is worse? But there is caching built into zfs, which, although not native to linux, already works very well
