High-density server with a three-tier storage architecture to support a variety of storage workloads.

Delivering high-density storage and high compute performance for big data.

NF5266M6 is a 2U dual-socket storage server that adopts an innovative three-tier storage architecture. It features improved and optimized storage and compute performance, flexible configuration, and intelligent management. This storage 2U is suitable for big data, CDN, hyperconvergence, distributed storage, etc.

High-Density Storage Architecture and Breakthrough Compute Performance

2U supports up to 26x 3.5-inch drives to deliver 116% increased storage density compared with the traditional 2U 12 drive model. It also supports up to 8x 2.5-inch small drives, providing 100% higher SSD cache density than the previous generation.


2 Intel® Xeon® Scalable processors enable up to 44% higher performance than the previous generation, making it ideal for compute-intensive applications like big data.

Powerful IO Expansion and Flexible Configuration

High I/O expansion capability with 7 PCIe 4.0 slots, delivering 16GT/s transfer rate. Supports 200Gb network and ensures a low-latency experience.

The modular design allows the on-demand combination of storage and IO. It supports 8 x SAS/SATA/NVMe/E1.S SSDs to meet the needs of data tiering, and enables 1/10/25/100/200Gb NICs and SMART NIC to support various network requirements.

Intelligent Environment Sensing and Enhanced Data Security

Software and hardware design enables real-time monitoring of the temperature, airflow, and air pressure of the operating environment, deploying intelligent cooling strategy. This improves the service life of the drive and ensures the storage server is optimal operating state.

Multi-dimensional in/out status (chassis, drive bay, drive, etc.) guarantees component and drive safety. Monitoring of operation and maintenance of drives and support of secure erase enhance data security.

The Experts Weigh In on NF5266M6

Storage hardware specialists remark on the NF5266M6’s unique tray-load system, configurability with PCIe and onboard M.2 slots, and stable performance, concluding it a “compelling high-density storage platform”.
