Primary Data (www.primarydata.com), the Data Virtualization company extending pNFS, just announced new targets as data servers within the data lake built and controlled by its DataSphere software. With this new release Primary Data supports now EMC ScaleIO, EMC Isilon and Amazon S3. The company is able to support multiple back-end - block, file and object - local or remote - and unify them within a unique namespace. For some people who wish some background on Primary Data, I invite to read a post I wrote 2 years ago available here. Good progress.
