VCache provides a nearly-transparent persistent memory for Haskell supporting ACID transactional variables and large structured values. The virtual address space is modeled above a memory mapped file via LMDB, with structure sharing and incremental reference counting GC.

VCache was developed as an alternative to acid-state in a context where the persistent data is much bigger than the active working set and RAM. Other similar packages include TCache and perdure. See the home page for a simple comparison.
