NetApp Finds ATTO FC HBAs have Half the Latency of Competitors

NetApp and ATTO collaborate on Solution Guide for Professional Media Workflows and Fibre Channel

Aug 10, 2020

ATTO Technology, Inc., a global leader of network, storage connectivity and infrastructure solutions for data-intensive computing environments for over 30 years, announced NetApp, Inc. has found ATTO Celerity™ Fibre Channel host bus adapters 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 Media and Entertainment”, which is available on

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. Fibre Channel 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.

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

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

ATTO Celerity HBAs, ATTO XstreamCORE® intelligent bridges and ATTO ThunderLink® Thunderbolt™ to Fibre Channel adapters all feature ADS and MultiPath Director as core technologies. As the NetApp data shows, these are the best Fibre Channel solutions for media workflows.
