Open Source Storage: 64 Applications for Data Storage

Download the authoritative guide: Enterprise Data Storage 2018: Optimizing Your Storage Infrastructure

As data storage needs continue to grow and many organizations move toward software-defined infrastructure, more enterprises are using open source software to meet some of their storage needs. Projects like Hadoop, Ceph, Gluster and others have become very common at large enterprises.

Home users and small businesses can also benefit from open source storage software. These applications can make it possible to set up your own NAS or SAN device using industry-standard hardware without paying the high prices vendors charge for dedicated storage appliances. Open source software also offers users the option to set up a cloud storage solution where they have control over security and privacy, and it can also offer affordable options for backup and recovery.

The list below features 64 open source storage projects that are among the best options available for enterprises, SMBs and individual users. Please note that this is not a ranking. Entries are organized into categories and then alphabetized within the categories.

If you know of additional open source storage applications that you believe should be on our list, feel free to note them in the Comments section below.
