SC25: ATTO Technology Showcases High-Performance Connectivity Innovations

ATTO Technology, Inc. announces it will showcase its high-performance storage and network connectivity products at SC25, the international conference for HPC, networking, storage, and analysis, at the America’s Center Convention Complex in St. Louis, MO, November 18–20, 2025, at booth #4625.

The exhibition at booth #4625 will highlight the company’s latest Ethernet and Fibre Channel (FC) solutions, designed to meet the demands of HPC workloads in data centers, scientific research, AI/ML applications, and other data-intensive environments. The firm is also pleased to host IBM Storage in their booth this year.

ATTO Performance Ethernet integrates FastFrame NICs with ATTO360 Networking, providing optimized network management for high-throughput applications. The recently launched FastFrame N424 Quad Port 25GbE NIC delivers 25Gb/s per port with 1µs latency via RoCE support, reducing CPU overhead for AI training and HPC simulations. It includes advanced offloads such as LRO, LSO, TSO, and RSS for efficient virtualized workloads.

ATTO360 Storage software unifies management, optimization, and analytics for ATTO Fibre Channel, SAS, and NVMe adapters in a single intuitive dashboard, combining ConfigTool, MultiPath Director, and ATTO ExpertAI for 1-click tuning profiles, dynamic load balancing, failover assurance, and real-time bottleneck detection.

Celerity 64Gb Gen 7 PCIe 4.0 Host Bus Adapters (HBAs) offer deterministic performance with half the latency of competitors, leveraging an advanced software driver architecture to optimize data pathways in all-flash data centers. The new Celerity FC-644E Quad Port HBA provides up to 256Gb/s aggregate bandwidth across four ports, supporting FC-NVMe fabrics for ultra-low latency access to shared storage in demanding AI and HPC environments. Available in single-, dual-, and quad-port configurations, these HBAs are backward compatible and support Windows, Linux, macOS, VMware, and other OSs.

“At SC25, we’re demonstrating how our hardware and software synergy delivers reliable, low-latency connectivity to power the next wave of HPC and AI advancements,” said Tim Klein, president and CEO, ATTO Technology. “Our solutions enable customers to focus on innovation while ensuring peak performance and seamless integration.”

The company is hosting IBM Storage at SC25, showcasing the Diamondback Tape Library alongside XstreamCORE Intelligent Bridges, highlighting the powerful integration of tape storage and network connectivity for backup, archive, and DR operations.

XstreamCORE 7600 extends FC access to block storage for up to 64 servers over distances exceeding 500km with less than 4ms added latency. XstreamCORE ET 8200/8200T intelligently bridges SAS block devices such as JBODs or tape libraries to iSER or iSCSI Ethernet networks with performance to up to 64 servers with less than 2ms of added latency.

XstreamCORE 8100T intelligent bridge offers a compact, energy-efficient 1U bridge for integrating SAS tape drives into iSCSI environments, ideal for data centers and remote HPC facilities.

Additional products on display include ExpressNVM Smart NVMe Switch Host Adapters for high-bandwidth NVMe fabrics and ExpressSAS 24Gb/s SAS HBAs for robust SAS/SATA connectivity.
