Design for High Reliability, High performance, High Density

New generation H3C UniServer R6700 G3 adopt a high density architecture to provide outstanding performance with 4 sockets and achieve high reliability and flexibility within only 2U rack. This model supports up to 26 SFF drives include optional 18 NVMe SSD drives. R6700 G3 server features Enterprise-grade RAS make it a decent choice for core workload,virtualization,Database,data-processing and high-density computing application.

H3C UniServer R6700 G3 utilizes the most recent 2nd generation Intel® Xeon® scalable processor. With 11 x PCIe3.0 I/O slot to reach excellent IO scalability. 94%/96% power efficiency and 5~45℃ standard Operating temperature Provide users with higher energy efficiency returns.

You can use the R6700 G3 to support the following services:

- Virtualization — Support multiple types of workloads on a single server to save space

- Big Data — Manage exponential growth of structured, unstructured, and semi-structured data.

- Applications centered on storage — Remove I/O bottleneck and improve performance

- Data warehouse/analysis — Query data on demand to help service decision

- Customer relationship management (CRM) — Help you to gain comprehensive insights into business data to improve customer satisfaction and loyalty

- Enterprise resource planning (ERP) — Trust the R6700 G3 to help you manage services in real time

- Virtual desktop infrastructure (VDI) — Deploys remote desktop service to bring great office agility and enable telecommuting with any device anywhere anytime

- High-performance computing and deep learning — Provide 3 dual-slot wide GPU modules in a 2U footprint, meeting the requirements of machine learning and AI applications

The R6700 G3 supports Microsoft® Windows® and Linux operating systems, as well as VMware and H3C CAS and can operate perfectly in heterogeneous IT environments.
