[PVE-User] bcache, lvmcache, flashcache on proxmox 4?

[Dmitry Petuhov]

Cheap ssd in production server is generally bad idea. They may have some critical drawbacks like low lifetime on high-write workloads and low performance on some workloads.

So what you want? Locally cache  *shared* iSCSI storage on PVE nodes? PVE doesn't have methods for this. You could try do something like that manually, but it's pretty dangerous.
