PCIe x8 to dual M.2 NVMe adapter with RAID support for high-bandwidth storage expansion.
Scaling storage capacity in PCIe slot-limited servers often requires balancing SSD density with bandwidth availability. The LRNV9541-2IR addresses this by converting a single PCIe 3.0 x8 slot into two high-speed M.2 NVMe connections, eliminating the need for bulky external enclosures while maintaining direct CPU access.
Powered by the Marvell 88NR2241B0 controller, this adapter delivers 64Gbps total transfer speed across two M.2 M-key interfaces. This non-blocking interconnect ensures maximum throughput for both drives simultaneously, supporting RAID 0, RAID 1, and JBOD configurations to enhance data redundancy or performance as needed.
Ideal for server, storage, and communication platforms requiring high-resolution graphics support alongside fast storage. The LRNV9541-2IR optimizes peer-to-peer traffic and multicast capabilities, making it a robust solution for data center storage expansion and GPU-accelerated workloads.
Based on Marvell 88NR2241B0 main control solution for reliable performance.
Expands storage space with 2 M.2 SSDs (2242/2260/2280mm) via PCIe x8.
Supports RAID 0, RAID 1, and JBOD for flexible data management.
Delivers 64Gbps transfer speed with non-blocking interconnect architecture.
Optimized to support high-resolution graphics and peer-to-peer traffic.
