Harmonic MediaGrid

Harmonic MediaGrid is a highly scalable, Ethernet-based shared storage system optimized for digital media workflows.

MediaGrid-4000 Shared Storage

Harmonic’s MediaGrid is an ideal fit for digital media applications requiring shared, real-time storage, such as ingest, playout, archive, edit-in-place, collaborative editing, transcoding and over-the-top (OTT) adaptive bitrate streaming. Simple to deploy, manage and scale, MediaGrid storage accelerates file-based workflows and provides the ability to manage the entire asset lifecycle. The system reduces the cost of storing media nearline, making it practical to 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. Media operations can start with smaller MediaGrid systems — as little as 24 TB of usable capacity — and seamlessly scale to petabytes of capacity and tens of gigabytes per second of throughput. An industry-leading, high-density storage option — up to 504 TB of raw capacity in 5 RU — can reduce rack space by up to 60% and lower storage-related costs by up to 30%, minimizing total cost of ownership (TCO) through its exceptional price/performance capabilities.

MediaGrid Features

High Scalability

MediaGrid is based on a fully distributed scale-out architecture, resulting in increased performance as additional storage nodes are added. As the system is expanded, bandwidth and capacity increase linearly, actually improving access speed to content already on the system.

Simple and Cost-Effective

Based on standard hardware components and cost-effective Ethernet technology, MediaGrid is economical to purchase and maintain. There’s no need for file system reconfiguration as you scale, or for file system defragmentation as the file system ages.

Optimized for Media Workflow

MediaGrid works with dozens of leading media systems, including Harmonic Spectrum media servers and ProMedia™ X Origin multiscreen media servers. It also enables collaborative editing workflows with nonlinear editors, such as Apple® Final Cut Pro®, Avid® Media Composer® and Adobe® Premiere® Pro.

Reliability and Availability

MediaGrid systems have no single point of failure, and leverage features such as dual active-active controllers with transparent failover, redundant data paths to protect against storage node failures, and transparent client failover to protect against controller failures. No down time is required even for activities such as software and firmware upgrades or adding storage nodes.
