Engineered to give you the edge

Celerity HBAs are engineered differently and have an advantage over the leading competitor embedded directly in the processor’s architecture. Every element of the design is selected for quality and speed. We start with a multi-core Fibre Channel ASIC supporting multiple dynamic data threads to provide incredible performance in keeping data flow at optimum levels.

Adding our intelligent software driver stack further enhances our Celerity Fibre Channel HBAs by tuning to best optimize the data flow for your data patterns. It is no wonder that our HBAs are half the latency of our closest competitor and users continuously turn to ATTO to get the most out of their Fibre Channel infrastructure.

Architect the modern datacenter

Storage architects who demand extreme and reliable performance consistently turn to ATTO. 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.

Custom connectivity

Available in low-profile single-, dual-, and quad-port versions, 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.

Celerity HBAs support a wide breadth of operating systems for the most flexibility including Windows®, Linux®, illumos, FreeBSD, VMware and macOS®.

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 workstations. They provide load balancing and path failover protection to improve overall Fibre Channel SAN efficiency with consistent uninterrupted access to your data.

Reliable performance is our specialty

Move large volumes of data with fast, predicable and deterministic response time by optimizing performance up to 6400MB/s per channel and support for PCIe 4.0. 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.
