PCIe 5.0 x16 to dual MCIO 8i retimer adapter for high-speed signal extension.
Scaling high-density storage in AI computing clusters often faces signal integrity challenges over long distances. The LRSV9501-2E PCIe 5.0 x16 Retimer Adapter solves this by extending host signals to external JBOF devices with enhanced quality, ensuring reliable low-latency data transfers.
Powered by the Broadcom BCM85657 controller, this card delivers 32GT/s link speed across two MCIO 8i interfaces. It supports flexible lane bifurcation (1x16, 2x8, 4x4), enabling up to 128GB/s of bidirectional bandwidth. This eliminates storage bottlenecks in GPU-accelerated servers by maintaining signal fidelity for high-speed NVMe expansions.
Ideal for building scalable storage systems and AI platforms, the LRSV9501-2E ensures protocol-transparent forwarding compliant with CXL 2.0 and PCIe Gen5/4/3/2/1 standards. Its robust design supports diverse operating systems, providing a seamless bridge for enterprise data center deployments requiring maximum I/O throughput.
Supports PCIe 5.0 x16 host interface with 32GT/s link speed for maximum bandwidth.
Based on Broadcom BCM85657 controller for reliable signal retiming and integrity.
Fully compliant with Compute Express Link 2.0 standards for advanced memory pooling.
Supports 1x16, 2x8, and 4x4 lane configurations for versatile device connectivity.
Equipped with two MCIO 8i connectors for high-density external storage expansion.
High-quality optical modules and cables for optimal compatibility with your network adapter.
