PCIe 3.0 x8 to Quad M.2 NVMe SSD Adapter PLX PEX8747 Switch, Multi-Host Failover Support, High-Bandwidth Non-Blocking Architecture, for Server, Storage, and High-Availability Systems

Unlock enterprise-grade storage scalability with this PCIe 3.0 x8 to Quad M.2 NVMe SSD Adapter, powered by the PLX PEX8747 PCIe switch. Designed for demanding server, storage, and high-availability applications, this adapter allows you to install four M.2 NVMe SSDs into a single PCIe slot, delivering exceptional storage density and performance for next-generation data centers and enterprise platforms.

High-Performance PCIe Switching Architecture

At the heart of this adapter is the PLX PEX8747, a field-proven PCIe 3.0 switch that provides high-bandwidth, non-blocking interconnect between the host system and connected NVMe SSDs. With support for fan-out, aggregation, and peer-to-peer traffic patterns, this architecture ensures optimal performance across a wide range of deployment scenarios.

Multi-Host & High-Availability Features

One of the most advanced capabilities of this adapter is its support for multi-host configurations and failover redundancy. The architecture enables:

1. 1+1 host configuration: One active host with a backup for failover protection
2. N+1 host configuration: Multiple active hosts with one backup for scalable redundancy
3. High-availability systems: Clustering and fault-tolerant configurations for mission-critical environments

PCIe 3.0 x8 Bandwidth

The adapter utilizes a PCIe 3.0 x8 host interface, delivering up to 8GB/s of aggregate bandwidthsufficient to support multiple NVMe SSDs operating simultaneously at full speed. Backward compatibility with PCIe 2.0 and 1.0 ensures broad platform compatibility.
