ATTO ExpressNVM 8-Port x16 PCIe 4.0 Smart NVMe Switch Adapter, Low Profile

The ATTO ExpressNVM ENVM-S48F-000 is a high-performance NVMe switch adapter designed for demanding enterprise and data center environments. Leveraging PCIe 4.0 technology, this low-profile, half-length card provides eight NVMe ports via two SFF-8654 SlimSAS connectors, each supporting PCIe 4.0 x4 lanes. The integrated Smart NVMe Switch enables advanced features such as NVMe-oF readiness, SR-IOV, hot-plug support, and comprehensive power management, making it ideal for HPC, AI/ML, data analytics, and cloud infrastructure.

Advantages

Unlock the full potential of NVMe storage with the ATTO ExpressNVM adapter. Its PCIe 4.0 x16 host interface delivers up to 128 GB/s bidirectional bandwidth, eliminating bottlenecks for data-intensive applications. The low-profile form factor ensures compatibility with a wide range of servers, while passive cooling maintains silent operation. In-band (NVMe-MI) and out-of-band (SMBus/I2C) management provide flexible monitoring and control. Field-upgradable firmware and UEFI boot support simplify deployment and maintenance.
