ICY DOCK PCIe 4.0 x16 NVMe Adapter Card with 2 x SlimSAS 8i (SFF-8654) Ports & Redriver (PCIe Bifurcation Required) - EXLink MB308A

The ICY DOCK EXLink MB308A is a high-performance PCIe 4.0 x16 adapter card with two SlimSAS 8i (SFF-8654) ports for direct NVMe connectivity. Equipped with an integrated redriver IC and PCIe clock buffer, the MB308A ensures signal integrity over longer cable routes, ensuring stable speed and reliability according to PCIe Gen4. Validated with ICY DOCK NVMe mobile racks and chassis, the MB308A provides a reliable foundation for servers, workstations and validation laboratories where consistent NVMe storage performance is crucial. Please note: The MB308A requires the host board to support PCIe bifurcation in mode (x4, x4, x4, x4) to access up to four NVMe SSDs. This adapter itself does not provide bifurcation function. With a PCIe 4.0 x16 interface that delivers a total bandwidth of up to 256Gbps, the MB308A is designed for motherboards that support lane bifurcation (x4, x4, x4, x4). If this feature is enabled, the adapter can connect up to four NVMe SSDs via its two SlimSAS 8i ports. If the motherboard does not support bifurcation, only a single SSD may be detected. In NVMe environments with high data rates, PCIe signals can lose quality across longer traces or external cables. The MB308A's integrated redriver balances and amplifies the signals so that SlimSAS connections maintain full PCIe Gen4 speed, even with qualified long-range cables. This ensures reliable data throughput on demanding workloads such as AI/ML training, data validation, and scientific simulations.
