Excellently handling of data-intensive workloads with flexible expansion

The R4300 G3 server realize the comprehensive needs of high storage capacity, efficient data calculation, and linear expansion within 4U rack. This model is suitable for multiple industries such as government, operator, and the Internet.

As an advanced high-performance dual-processor 4U rack server, the R4300 G3 features the most recent Intel® Xeon® Scalable processors and six-channel 2933MHz DDR4 DIMMs, increasing server performance by 50%. With up to 2 double-width or 8 single-width GPUs, equipping R4300 G3 with excellent local data processing and real-time AI acceleration performance.

The R4300 G3 server support up to 52 drives, seamless select from M.2 to NVMe drives and flexible NVDIMM/DCPMM combination as well as Optane SDD/NVMe high-speed flash.

With up to 10 PCIe 3.0 slots and up to 100 GB Ethernet card 56Gb、100Gb IB card, Server can easily achieve reliable and flexible I/O expansion to deliver high volume and concurrent data service.

R4300 G3 Server support power supplies with 96% efficiency that greatly improves data center efficiency and reduce the datacenter cost.

R4300 G3 provide a favorable linear expansion of DC-level storage capacity. It can also support multiple modes Raid technology and power outage protection mechanism to make the server an ideal infrastructure for SDS or distributed storage,

- Big Data – manage exponential growth in data volume includes structured, unstructured, and semi-structured data

- Storage-oriented application – eliminate I / O bottlenecks and improve performance

- Data warehousing/Analysis – extract valuable information for wiser decision-making

- High-performance and deep learning–Powering machine learning and artificial intelligence applications
