I recently picked up a gently used, off-lease Panasas ActiveStor 3100 Parallel Storage Cluster from eBay. The unit powers on and I have been able to console in to the management and storage blades. The next step is to bring the cluster online and learn more about the activeScale operating environment (which appears FreeBSD based..) and the PanFS parallel file system. Documentation online is scarce without an active support contract with Panasas. Look here for updates as they happen.
