PCIe 5.0 x16 to 2-port MCIO 8i retimer NVMe expansion card for servers and workstations.
When data-intensive workloads cause storage I/O bottlenecks in servers and workstations, the lack of PCIe bandwidth stalls critical applications. The LRSV9570-2I NVMe expansion card solves this by leveraging PCIe 5.0 x16 connectivity, enabling direct attachment of two MCIO 8i NVMe SSDs for seamless high-speed data access.
Powered by a Silicon Innovation XRET5032 retimer, it delivers 32 GT/s per lane and supports 1x16, 2x8, or 4x4 bifurcation, eliminating bus contention and ensuring smooth multi-device operation. The dual MCIO 8i ports provide versatility for SSD direct-attach, backplane expansion, and GPU accessory expansion, effectively doubling storage possibilities.
The card’s support for CXL 2.0 Alt mode enables memory sharing, cutting latency for high-performance computing tasks. With low-profile and full-height bracket options, wide OS compatibility (Windows, Linux, VMware), and a -10°C to 55°C operating range, the LRSV9570-2I meets demanding enterprise requirements for scalability and reliability.
Complies with PCIe 5.0, delivering up to 32 GT/s per lane for maximum data transfer efficiency.
Enables memory sharing between host and devices, reducing latency for high-performance workloads.
Supports 1x16, 2x8, and 4x4 splitting, adapting to diverse SSD and GPU expansion configurations.
Built-in Silicon Innovation XRET5032 retimer ensures robust signal quality for reliable 32 GT/s links.
Consumes only 6.1W minimum and 19.1W maximum, reducing thermal load in dense deployments.
Two MCIO 8i connectors allow direct NVMe SSD attachment, backplane expansion, or GPU accessory integration.
High-quality optical modules and cables for optimal compatibility with your network adapter.
