Skylable SX is a distributed object-storage software for clusters.
It was built bottom-up with the goal of being fast, secure, cost-effective and reliable.

It is easy to install and an entire SX cluster can be deployed in literally minutes by a junior sysadmin.

It supports nodes with different sizes, volumes with different number of replicas and it scales horizontally: you can hot-add new nodes while the cluster is being used.

The rebalance process makes sure that data is distributed in proportion to the size of the nodes and maximize space availability.

Skylable also supports deduplication, revisions, incremental transfers, and the S3 protocol.


Skylable Sx allows you to choose the most convenient way to access your data. That's the beauty of Open-Source!

If you are a developer, you can link your software to our client library libsx (LGPL licence) or interface with the SX API or re-use any existing S3 library.

If you are a sysadmin, you can use our command line tools (sxls, sxcp, sxcat, sxrm, ...).

If you are an end-user, you can safely synchronize your file between your devices and your Skylable cluster with SXDrive.

We also offer SXWeb, a web interface to access your data from any browser, for those hard times when you don't have your geeky gear with you.


  • We are using Skylable Sx as the storage backend for our Continuos Integration / Continuos Delivery system, based on Docker. We generate thousands of new Docker images every month for development and production use and we like to keep them around for future reference. Uploading these images to a public cloud is slow and also poses some security risks so we decided to deploy our own Docker registry and plug it into Skylable Sx.

  • Our wiki platform has 1.5 million users and hosts more than 22 million web pages. Every day our wikis are edited 13.000 times. We wanted a fast way to store and retrieve our backups. We tried Skylable and we were impressed by the reliability of the software and by the increase in transfer speed.

  • We deployed a Skylable cluster in the datacenter near our startup accelerator and started offering 100GB of free cloud storage to every person taking part to our accelerator program. The users are using SXDrive to synchronize their work from their laptops and mobiles. They feel safe to know that they can still access their files anytime, even in case of disk failure.

  • “Skylable Sx is exactly what we needed for our world-class organization. We managed to easily share our data among more than 20 of our sales branches and representative offices all over the world. We achieved this in a record timing and well aware that all data is safely stored in our private cloud, which was the most challenging and critical objective for us.”

  • We started using Skylable Sx and LibreS3 for our services after doing extensive benchmarks on our HPC cluster a large Italian research center focused on the development of systems for naval defence and security. We were impressed by the performance and reliability and we started promoting the use of Skylable Sx also to our strategic partners.
