Under The Hood
SpanFS exposes industry-standard, globally distributed NFS, SMB, and S3 interfaces. The IO Engine manages IO operations for all the data written to or read from the system. It detects random vs. sequential IO profiles, splits the data into chunks, performs deduplication, and directs the data to the most appropriate storage tier (SSD, HDD, cloud storage).
To keep track of the data, SpanFS also includes a completely new Metadata Store. The Metadata Store is based on a consistent, distributed NoSQL store for fast IO operations at scale. And SnapTree® provides a distributed metadata structure based on B+ tree concepts. SnapTree is unique in its ability to support unlimited, frequent snapshots with no performance degradation.
