Gluster's open source alternative to traditional scale-out

–The Gluster Storage Platform pools and virtualizes storage resources under a unified global namespace managed as single entity, providing an alternative to proprietary scale-out architectures and file systems such as ZFS, Lustre and GFS, according to an article posted on InfoStor sister site Enterprise Storage Forum.

Here are some excerpts from the article:

Gluster president and CEO Ben Golub says that traditional storage systems designed to deal with structured information such as databases are expensive, don't scale well, are focused on transactions, and weren't designed to cope with millions of users and petabytes of photos and videos.

Gluster CTO and co-founder AB Periasamy notes that many vendors have attempted to solve the problem, but "their efforts to create scalable file systems for NAS and unstructured data have resulted in complexity. None of these systems achieved the desired level of scalability," he said, citing NetApp's Data ONTAP as an example.

Gluster claims to have resolved the scalability challenge by eliminating the need for the metadata server (MDS). Gluster's algorithms circumvent the need for an MDS by allowing the Gluster Storage Platform to automatically know where data resides.

A free distribution of the software is available on Gluster's website, but the company has a similar model to Red Hat with Linux in that it offers commercial support for the open source platform.
