I have heard/read about systems from Sun and NetApp using SDs for

faster for reads and the other for writes). The storage solution from
Sun is based on Solaris with ZFS.
I know too little about filesystems design to know exactly how they
do
this, but can someone think of a way this could be implemented in
btrfs?
Linux already has second-level¹ cache layer, it called FS-Cache.
For now,
the sole user is NFS. btrfs could take advantage of FS-Cache also.
I googled around a bit for this, but couldn't find anything useful.
Where can I find anything about this second (or fifth) level caching?

I all pedagogikk er det essensielt at pensum presenteres
intelligibelt. Det er et elementært imperativ for alle pedagoger å
unngå eksessiv anvendelse av idiomer med fremmed opprinnelse. I de
fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
