Zero-Second Fault Tolerance: VolPack Safeguards Every Broadcast

From Campus Newsroom to Professional Broadcasting - A Perfect Validation

Arizona State University's Walter Cronkite School of Journalism & Mass Communication is not only one of America's premier journalism and communications education institutions, but also a truly operational media enterprise. This school, named after the legendary anchor, has built a modern 225,000-square-foot news production center in downtown Phoenix with an investment of $71 million.

The scale of the school is impressive: 14 digital newsrooms, 2 professional studios, 500 Apple Mac workstations equipped with Final Cut Studio, and enterprise-grade Apple Xsan storage infrastructure. The news programs broadcast four nights a week are not student assignment demonstrations, but official broadcast programs reaching over one million viewers.

Zero-Tolerance Requirements of Broadcasting Operations

In this environment, technical failures are not just system problems—they're broadcast incidents. From video footage capture to final playback, the entire production workflow must run seamlessly on Mac workstations and Xsan storage systems.

Student reporters upload field footage and news scripts to Xsan shared directories, student editing teams use Final Cut Pro for post-production, and after faculty review, content goes through news broadcast management systems and Sienna video production software for broadcast scheduling. This workflow faces stringent technical requirements:

• Zero Broadcast Interruption: News program air times cannot be delayed by even a second
• High-Performance Processing: Must simultaneously support 4 streams of DVCPRO HD high-definition video
• Real-Time Failover: When primary systems encounter problems, millisecond-level automatic switching is required
• Absolute Data Security: All data, including Retrospect backup systems, must be protected

Validation Through Real-World Experience

After evaluating various network storage solutions, Sasan Poureetezadi, the school's Director of Computer Services, chose a redundant architecture that deployed two 24TB RAID systems in separate buildings one block apart, connected via fiber channel networks, with tape libraries configured for long-term preservation.

This system faced two critical moments during actual operation: one SAN switch hardware failure and one network connectivity issue. In both critical moments, the system demonstrated perfect automatic response capabilities, instantly switching to backup paths with no impact on news broadcasts.

"The system has provided stable storage solutions for our critical playback and backup data, achieving continuous and uninterrupted protection." — Sasan Poureetezadi

VolPack: Next-Generation Shared Storage Inheriting Professional Broadcasting Experience

Based on our real-world experience at institutions like the Cronkite School of Journalism, Accusys has launched the VolPack shared storage platform. This is not simply a hardware upgrade, but a complete solution redesigned specifically for broadcast-grade applications.

Enterprise-Grade Redundant Architecture Design

VolPack employs a dual-controller fault-tolerant architecture, providing reliable data access protection in single-point-of-failure scenarios. The system supports Active-Passive mode, with the primary controller handling all I/O requests while the passive controller stands by as backup. When the primary controller fails, the passive controller immediately takes over all workloads, quickly completing system switchover to minimize system downtime and ensure data access continuity and reliability.

Critical Component Fault Tolerance

Beyond dual-controller design, VolPack implements redundant configuration across all critical components: dual power supplies, multi-path data transmission, and hot-swappable drive support. The system features intelligent fault detection mechanisms that can issue early warnings when components show initial signs of abnormality and automatically activate backup mechanisms to prevent single-point failures from affecting overall operations.

Optimized for Video Workflows

• Multi-Protocol Support: Simultaneously supports FC, iSCSI, and SAS communication protocols to meet connection requirements for different devices and platforms
• Cross-Platform Collaboration: macOS, Windows, and Linux systems can connect simultaneously, supporting collaborative work in mixed environments
• High-Speed Transmission: I/O performance optimized for 4K/8K video footage, supporting multi-path parallel editing operations
• Flexible Expansion: Capacity expansion capability from TB-level to PB-level to meet application requirements of different scales

Application Scenarios: From News Broadcasting to Film Production

• Broadcast Television Stations: Supports real-time requirements of news program production, ensuring uninterrupted broadcasting
• Film Post-Production: Provides large-capacity, high-performance shared workspace to accelerate post-production workflows
• Advertisement Production: Meets fast-paced delivery requirements, supporting multiple simultaneous projects
• Educational Institutions: Professional training environments like the Cronkite School of Journalism to cultivate the next generation of media professionals

Value Promise Beyond Technical Specifications

Choosing VolPack means choosing not just a storage device, but a reliable partner proven in real-world applications. We understand the critical characteristics of broadcasting operations: time cannot be rewound, quality cannot be compromised, and systems cannot go down.

As demonstrated by the success at the Cronkite School of Journalism, a truly professional storage solution must exhibit absolute reliability in critical moments. VolPack inherits this design philosophy, providing a solid technical foundation for modern media workflows.
