Inspur NF5266M6

High-density Rackmount Storage Server


NF5266M6 is a 2U dual-socket storage server that adopts an innovative three-tier storage architecture. It has improvement and optimization in storage and computing performance, flexible configuration, and intelligent management. It is suitable for big data, CDN, hyper-converged, distributed storage, etc.

Innovative Storage Architecture and Breakthrough Computing Performance

2U space supports up to 26×3.5-inch drives. Compared with the traditional 2U12 drive model, the storage density is increased by 116%. It also supports up to 8 x 2.5-inch small drives and the SSD cache density is 100% higher than the previous generation.

2×scalable processors enable even outstanding CPU computing power. Compared with the previous generation, this machine has the performance boosted by up to 44%, ideal for demanding scenario of computing power in big data analysis..

Powerful IO Expansion and Flexible Configuration

I/O expansion capability is increased by 75%. The transfer rate of PCIe4.0 is doubled and reaches 16GT/s. Support the 200Gb network and ensure 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, and intelligently cooling strategy; improves the service life of the drive and ensures the storage server is in the best operating state.

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