Unison Petabyte
Complete Scale-out Performance Solution

Unison Petabyte (featured at Super Computing as the Portable Petabyte) is a high performance, highly dense, turnkey parallel file system solution that is designed, built, and configured for your needs.

HPC and analytics benefit from Unison Petabyte when powered by BeeGFS©, a parallel file system tailored for high-performance environments. The unique metadata architechure of BeeGFS speeds up file creation, directory stat, and other functions that can slow other platforms down.

Data silos and storage complexity are eliminated in multi-tenancy and Cloud deployments with Unison Petabyte powered by Ceph©. Configured to support object, block, and file storage as well as OpenStack® and Hadoop®, Unison Petabyte Ceph provides maximum storage flexibility.

Unison Appliances are the perfect building block for highly-available clustered storage. Unison Petabyte takes those blocks and builds a complete solution, racked and ready for implementation.

Increase Ceph Performance with Scalable Informatics Unison

This white paper compares the performance of Unison, powered by Ceph, to that of the reference architecture as published by Red Hat. Unison demonstrated speeds of 1.8X for reads and 2.3X for writes versus their performance metrics.
