NetApp Finds Atto HBAs Have 50% Less Maximum Latency

Atto Technology, Inc. announced NetApp, Inc. has found its Celerity FC HBAs have over 50% less maximum latency and overall less average latency than the closest competing products.

These performance metrics were generated by benchmarks NetApp conducted as they collaborated with Atto to find the best way to address challenges to media workflows. The result was published in Increased Streaming Capacity Solutions for M&E.

Using a multiple single threaded frametest, Atto products were able to achieve 38.5GB/s equating to 32 simultaneous 4K streams at 24fps without any dropped frames. That’s 50% less max latency and overall less average latency than the closest competitor. The combination of Atto MultiPath Director and Atto Advanced Data Streaming (ADS) kept latency low, leading to these impactful performance results.

Latency is a significant cause of poor performance in professional media applications and can lead to other inefficiencies along the production chain. In 2020 latency is still a nagging challenge faced by media editors and content creators. FC is a low latency technology that provides deterministic throughput and reliability which is why it remains a key storage network technology used for media workflows.

ADS is proprietary technology built into host adapters that is designed to manage latency in high-bandwidth environments. it provides controlled acceleration of data transfers by utilizing a combination of features to move large amounts of data faster.

MultiPath Director is a specialized multi-pathing driver incorporated into Celerity FC HBAs. Multipath Director implemented across all hosts improves overall FC SAN efficiency with consistent uninterrupted access to data through failover and failback protection. Load balancing increases overall system performance by using more than one FC path to transfer data.

Atto Celerity HBAs, Atto XstreamCORE intelligent bridges and Atto ThunderLink Thunderbolt to FC adapters all feature ADS and MultiPath Director as core technologies. As the NetApp data shows, these are FC solutions for media workflows.
