Data Protection on NV-DIMM - Dr. Hannes Reinecke, SUSE Linux GmbH

NV-DIMM has been presented as delivering high-speed, memory-like performance while allowing for large capacity and lower prices than normal DRAM.
One of the most common usecases for NV-DIMM is the so-called DAX (direct access) mode, which allows NV-DIMMs to be used for storing filesystem data but at the same time providing all the benefits of NV-DIMMs.
In order to use these filesystems in mission-critical scenarios some kind of data protection is required. On normal block devices such protection would be guaranteed by RAID systems, and the linux stack does have a full-blown RAID implementation.
However, using this implementation on NV-DIMMs make it impossible to use the DAX capabilities.
This presentation will be focussing on the challenges when implementing data protection for NV-DIMMs, and will be presenting some possible mechanisms for providing data protection while retaining DAX capabilities.
