ATTO Celerity™ Fibre Channel host bus adapters (HBAs) deliver the fastest data throughput (both MB/s and IOPs) available for today's most demanding storage environments, including physical and virtual datacenters, tape streaming and backup, rich content delivery, and server clustering.

Powering the modern data center

Celerity HBAs unleash the performance of all-flash data centers with the support of NVMe fabric technology for demanding workloads that require extreme performance, ultra-low latency, and storage persistency to shared storage resources.

Engineered for performance

Celerity HBAs have an advantage over the leading competitor embedded directly in the processor's architecture. The ATTO controller features multiple cores, providing full IOPS performance to a single port in "active standby" mode on a dual-port HBA. If a port, cable or SFP fails a port on the ATTO adapter can support up to 2.5X as many IOPS as the competitive HBA. ATTO Celerity HBAs allow sustained maximum performance, enabling users to continue to meet service level agreements.

Flexible configuration options

Available in low-profile single-, dual-, and quad-port versions, ATTO Celerity HBAs are backward compatible, reducing the complexity of deploying and managing the SAN, and take full advantage of advancements for reliability and forward error correction to improve network performance and resiliency.

Connect your workstation to enterprise storage

ATTO Celerity HBAs, featuring Multipath Director™ technology, are the only solution that allows direct connectivity to enterprise storage not just for servers, but also Windows®, Linux®, and macOS® workstations. They provide load balancing and path failover protection to improve overall Fibre Channel SAN efficiency with consistent uninterrupted access to your data.

Celerity - the ATTO Difference

Optimize performance to power real-time decision-making

Move large volumes of data with fast, predicable and deterministic response time by optimizing performance up to 3200MB/s per channel. Built into every Celerity HBA, ATTO Advanced Data Streaming (ADS™) technology manages latency by providing controlled acceleration for smooth data streaming and allows you to maintain the highest consistent performance in data intensive environments.
