Free software that does smart SSD caching?

[lordsegan]

I want to play with SSD caching. I know that you can have an Arc/Zil in ZFS, but I was wondering if there are any "software SAN" OS products or other free products that do "smart caching" or application aware stuff? Or just anything in that space would be interesting to me.

Thanks!

Windows 8/Server 2012 Storage Spaces has Tiered Storage and SSD caching options.

Not to nitpick, but arc is ram cache, not ssd. And ZIL is not any kind of cache.

I haven't been able to find anything free, but this one is $15 and may rival Samsung's RAPID...
