Highlights: High Performance High Reliability, High Scalability

New generation H3C UniServer R6900 G5 adopt a modular architecture to provide outstanding scalable capacity supporting up to 50 SFF drives include optional 24 NVMe SSD drives.

R6900 G5 server features Enterprise-grade RAS make it a decent choice for core workload, virtualization Database, data-processing and high-density computing application.

H3C UniServer R6900 G5 utilizes the most recent 3rd Gen Intel®Xeon® Scalable processors. (Cedar Island),6 UPI Bus interconnection and DDR4 memory with 3200MT/s speed as well as New-generation PMem 200 series persistent memory to strongly lift the performance up to 40% compared with previous platform. With 18 x PCIe3.0 I/O slots to reach excellent IO scalability.

94%/96% power efficiency and 5~45℃ operating temperature provide users a TCO returns in a greener data center.

R6900 G5 is optimized for environments:

 Virtualization — Support multiple types of core workloads on a single server to simplify Infra-investment.

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

 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 R6900 G5 to help you manage services in real time

 High-performance computing and deep learning — Provide sufficient GPUs to support machine learning and AI applications

 The R6900 G5 supports Microsoft® Windows® and Linux operating systems, as well as VMware and H3C CAS and can operate perfectly in heterogeneous IT environments.
