Scalable media storage & high-density

Harmonic MediaGrid® is perfect for digital media applications requiring shared, real-time storage. You can ingest, playout, archive, edit, transcode and control over-the-top (OTT) adaptive bitrate streaming in one place.

Manage your entire asset lifecycle

Accelerate file-based workflows and manage your entire asset lifecycle with the Harmonic MediaGrid shared storage. You can collaborate your editing workflows with nonlinear editors, such as Apple Final Cut Pro®, Avid® Media Composer® and Adobe® Premiere® Pro.

Reduce the cost of media storage

Economically deploy multi-petabyte digital media libraries and archives for video on demand (VOD) and other applications. MediaGrid is purpose-built from the ground up to deliver high bandwidth and consistent low latency for video.

Protect your workflows

Protect your workflows against storage failures with dual-active controllers with transparent failover and redundant data paths. MediaGrid systems have no single point of failure to ensure uptime even during software and firmware upgrades.

Includes RAID 4 or RAID 6 for protection against unlikely events such as multiple drive failures.
