Inspur/IEIT NF5266M6 Rack Server Datasheet

Name: Inspur/IEIT NF5266M6 2U Rack Server - SunSpike
SKU: NF5266M6

System Overview

The NF5266M6 is a premium 2U dual-socket high-density storage server powered by 3rd Generation Intel® Xeon® Scalable processors (Ice Lake). Engineered specifically to resolve data storage bottlenecks in cloud environments, enterprise storage systems, and big data clusters, the NF5266M6 delivers extreme storage capacity, flexible I/O scalability, and high-throughput compute performance within a compact 2U chassis.

Key Highlights & Features

Ultra-High Storage Density: Accommodates up to 24x or 26x 3.5-inch SAS/SATA drives in a standard 2U chassis footprint, offering up to 40% higher storage density compared to standard 2U servers.
Balanced Compute Power: Supports up to two 3rd Gen Intel® Xeon® Scalable processors (up to 40 cores per socket, max TDP 270W), delivering significant generational boosts in IPC and memory bandwidth.
PCIe 4.0 & OCP 3.0 Expansion: PCIe 4.0 doubles data transfer speeds up to 16 GT/s per lane. Features a dedicated OCP 3.0 mezzanine slot supporting 1G/10G/25G/100G/200G network cards without consuming standard PCIe expansion slots.
Modular & Tool-Less Maintenance: Core service components—including drive bays, fan modules, and power supply units—are hot-swappable and designed for tool-less removal to maximize system uptime.
