Eight external SAS SATA ports

The ATTO ExpressSAS GT adapter provides eight external ports operating at 12 Gb/s each. It connects SAS or SATA storage to a PCIe 4.0 slot in enterprise servers or workstations. The card targets IT professionals building high-throughput arrays for databases, analytics or broadcast workloads.

Low-profile thermal design

A compact form factor fits dense chassis without blocking adjacent slots. Passive cooling relies on system airflow, adding no acoustic noise and drawing minimal power from the bus. The adapter is qualified for continuous operation in transactional data-centre environments.

Driver and management utilities

ATTO supplies cross-platform drivers and the ConfigTool suite for firmware updates, link diagnostics and RAID set configuration. These tools simplify deployment across Linux, Windows and VMware hosts. No cables, brackets or additional hardware are included in the package.
