The V6 EcoBoost engines are being assembled at Cleveland Engine Plant No. Some of the costs of US development and production were assisted by the $5.9 billion Advanced Technology Vehicles Manufacturing Loan Program of the Department of Energy.

When DataNode receives a data read request from a client, if the corresponding block is cached into SCM, DataNode will instantiate an InputStream with the block location path on SCM (pure java implementation) or cache address on SCM (PMDK based implementation). Consistent with DRAM cache, SCM cache also has no cache eviction mechanism. If multiple SCM volumes are configured, a round-robin policy is used to select an available volume for caching a block. Then, build Hadoop with PMDK support by referring to “PMDK library build options” section in `BUILDING.txt` in the source code. To enable PMDK based implementation, user should install PMDK library by referring to the official site. If PMDK native libs could be loaded, it will use PMDK based implementation otherwise it will fallback to java code implementation.

The latter implementation can bring user better performance gain in cache write and cache read. There are two implementations for HDFS SCM Cache, one is pure java code implementation and the other is native PMDK based implementation. And all HDFS cache directives keep unchanged. To enable SCM cache, user just needs to configure SCM volume for property “.dirs” in hdfs-site.xml.

Non-volatile storage class memory (SCM, also known as persistent memory) is supported in HDFS cache.
