Skylable SX is a reliable, powerful, fully distributed cluster solution for your data storage needs. It can aggregate the disk space available on multiple servers and merge it into a single storage system. The cluster makes sure that your data is always replicated over multiple nodes (the exact number of copies is defined by the sysadmin) and synchronized. It has built-in support for deduplication, client-side encryption, on-the-fly compression, and much more.
LibreS3 is a robust open source implementation of the Amazon S3 service, supporting a subset of the S3 REST API. Standard S3 client libraries and tools (for example python-boto, s3cmd, DragonDisk, etc.) can be used to access it. LibreS3 uses Skylable SX as the storage backend, which automatically provides data deduplication and replication.
