Dell PowerEdge NVMe PCIe Expansion Card
Need to add high-speed NVMe storage to a compatible Dell PowerEdge server? The Dell P31H2 NVMe SSD PCIe Extender Adapter provides a dedicated PCIe expansion path for connecting compatible NVMe U.2 SSDs to supported Dell server configurations. Unlike a conventional RAID controller, the P31H2 is designed as an NVMe PCIe extender adapter. It provides the connectivity required for supported NVMe storage configurations rather than performing hardware RAID processing. This makes the P31H2 a practical solution for enterprise server upgrades where high-speed NVMe storage needs to be integrated into compatible Dell PowerEdge R630, Dell PowerEdge R730, Dell PowerEdge R730xd, Dell PowerEdge R920, and Dell PowerEdge R930 platforms across Bangladesh.
Enterprise Performance and Architectural Overview
Enterprise server environments increasingly use NVMe SSDs alongside traditional SAS and SATA storage. NVMe communicates directly over PCIe, providing a high-bandwidth storage interface designed for demanding workloads. The Dell P31H2 provides a PCIe Gen 3 x16 host interface and four Mini-SAS HD SFF-8643 connectors for connecting compatible NVMe backplane configurations on Dell PowerEdge R630, Dell PowerEdge R730, Dell PowerEdge R730xd, Dell PowerEdge R920, and Dell PowerEdge R930 servers. For organizations upgrading compatible PowerEdge servers, the P31H2 provides a dedicated pathway for integrating NVMe storage without replacing the entire server platform.
Advanced Technical Standards and Multi-Gigabit Support
- Dell P31H2 NVMe Extender: Dedicated PCIe expansion adapter designed to route high-speed PCIe lanes directly to server NVMe drive backplanes.
- PCIe Gen 3 x16 Interface: High-bandwidth PCIe Gen 3 x16 host connectivity delivering full, unthrottled throughput to connected NVMe solid-state storage.
- 4 × Mini-SAS HD Ports (SFF-8643): Equipped with 4 discrete Mini-SAS HD internal connectors for connecting to compatible NVMe backplanes and cabling.
- Supports NVMe U.2 SSDs: Enables high-performance 2.5-inch U.2 PCIe NVMe solid-state drives for intensive enterprise storage workloads.
- Dedicated PCIe SSD Expansion: Provides direct PCIe connectivity for up to 4 NVMe SSD connections without consuming SAS/SATA controller channels.
- Supported Dell PowerEdge Servers: Engineered for Dell PowerEdge R630, Dell PowerEdge R730, Dell PowerEdge R730xd, Dell PowerEdge R920, and Dell PowerEdge R930 enterprise server platforms.

Deployment & Buying Guide
Recommended Deployment Pairing
Requires a Dell PowerEdge R630, Dell PowerEdge R730, Dell PowerEdge R730xd, Dell PowerEdge R920, or Dell PowerEdge R930 server with an available PCIe Gen 3 x16 riser slot, NVMe-compatible backplane, and Mini-SAS HD SFF-8643 cables.
Ideal Infrastructure Use Cases (Best For)
Key Deployment & Integration Considerations
- The Dell P31H2 is an NVMe PCIe extender adapter and does not provide hardware RAID functionality (software RAID or OS-level storage pools can be used for data protection).
- Requires appropriate Mini-SAS HD (SFF-8643) internal cables to link the card to the server NVMe drive backplane.
- Verify PCIe riser slot availability (x16 slot recommended) and backplane NVMe port support on Dell PowerEdge servers before installation.
