DELOCK SFF-8654 8i to 2x M.2 Key M NVMe SSD converter, model 64295

The DELOCK SFF-8654 8i to 2x M.2 Key M NVMe SSD converter (model 64295) is an interface adapter that allows installation of two M.2 Key M NVMe SSDs into a host system with an SFF-8654 8i port. Intended for servers, workstations and storage appliances, this converter preserves NVMe protocol performance while increasing drive density and deployment flexibility without modifying the host PCB or requiring additional drive bays.

Advantages

The adapter supports two independent M.2 Key M NVMe drives over a single SFF-8654 8i connection, maintaining PCIe/NVMe data paths and high throughput. Its compact form factor enables higher storage density in rackmount servers and compact workstations. The passive converter design avoids additional power or signalling conversion, reducing potential points of failure and keeping latency minimal. Installation and replacement of drives are simplified compared with custom carrier solutions.

Suitable for

• Expanding NVMe storage capacity in servers and storage arrays
• High-performance workstations requiring local NVMe drives
• Test benches and development systems evaluating multiple NVMe SSDs
• Data-centre applications where drive density and serviceability are important

Key specifications

• Interface: SFF-8654 8i host connection to 2x M.2 Key M sockets
• Supported drives: M.2 Key M NVMe SSDs (PCIe lanes per M.2 subject to host capability)
• Form factor: compact adapter designed for internal mounting in compatible chassis
• Signal type: NVMe / PCIe passthrough (no protocol translation)
• Power: uses host-provided power via SFF-8654 8i connector

How to use

Install two M.2 Key M NVMe SSDs into the M.2 sockets and secure them with the provided retention screws or standoffs. Connect the adapter to the host system using an SFF-8654 8i cable or direct port, ensuring the host is powered down during installation. After connection, power on the host and verify that the system BIOS/UEFI and operating system detect both NVMe drives. No driver is typically required beyond standard NVMe support provided by modern OS and firmware; confirm host PCIe lane allocation and BIOS settings if drives are not recognized.

Recommendations

For reliable operation, use M.2 Key M NVMe SSDs that conform to the host’s supported PCIe generation and lane counts, and ensure proper airflow and cooling in dense server environments to maintain drive performance and longevity.
