NVMe Extender Cards
Enabling Multi-Connector and Cabled Topologies
RT = Retimer
Requirements & Challenges
- NVME drives typically connect to the CPU through multiple connectors — interposer boards, midplanes/backplanes, and cables.
- Multiple SSD vendors/models must be qualified for a server design
- NVMe drives require hot-plug functionality
Aries Retimer Benefits
- Supports SSD-specific features such as hot-plug and bifurcation down to x2 link width
- Integrated capacitors reduce total retimer footprint size, fits easily on small mezzanine or interposer boards
- Built-in protocol analyzer for easy bring-up & debug
- Rigorous interop tests with numerous NVMe drives to ensure design confidence
