High performance 1U cache server with 24 DIMMs and 12 bays

Intel® Xeon® Scalable Platform design

RS700-E9-RS12 is built on the IntelXeonScalable Platform to deliver incredible 1U server performance, packing incredible power into minimal space. 24 DIMM slots provide best-in-class memory capacity and bandwidth, and an integrated I/O controller on the processor eliminates data transfer bottlenecks caused by discrete I/O chipsets for reduced latency and dramatically faster system performance.

User-friendly design for easier server maintenance

RS700-E9-RS12 features numerous user-friendly design features that simplify server maintenance. The server's Q-code is visible from the outside of the case to make diagnosing issues easier and more convenient. A tool-less rack rail kit is included for easy server installation and removal, and a tool-less, hot-swappable fan provides faster and simpler maintenance.

Advanced I/O support for 3+1 Expandability

RS700-E9-RS12 offers one full-high PCI Express 3.0 x16 slot (x16 link), one low-profile PCI Express 3.0 x16 slot (x8 link), one low-profile PCI Express 3.0 x8 slot (x8 link), and one OCP 2.0 Mezzanine slot (x16 link) to support 10G/25G/100G LAN card. The flexible expansions offer diverse applications in storage and networking to meeting the demands of future expansion and high scalability in a 1U server.

Expandable storage for faster transfer speeds

RS700-E9-RS12 features a port-to-port OCuLink design with 3X faster transfer speeds compared to PCIe switch IC solutions. Two M.2 slots accommodate 22110-size SSDs with support for additional OS storage and PCIe 3.0 x4 bandwidth 5.3X faster than 6 Gb/s SATA III for faster boot speeds. RS700-E9-RS12 is ideal for data centers with high storage and processing demands.

Fully integrated remote server management

The latest ASMB9-iKVM module enables remote BIOS updates, standalone KVM/Java utilities, video recording and BSOD capture. With out-of-band management, ASMB9-iKVM provides around-the-clock remote monitoring and diagnostics even if the server operating system is down or offline through a user-friendly, web-based graphical interface that works with all major browsers. ASUS Control Center (ACC) is a centralized and integrated IT management platform for monitoring and controlling ASUS commercial products, including servers, workstations and digital signage. ACC enables easier server management with functions such as BIOS updating without restarting the system, remote monitoring of multiple systems via mobile devices, and one-click software updates and dispatching.

Smart thermal design for energy efficiency

RS700-E9-RS12 features a smart thermal radar design with more ambient thermal sensors for the CPU, memory, GPU, SSD, LAN card and front-panel board that provide improved temperature monitoring and enable dynamic fan speed adjustment for better power efficiency. This smart thermal design reduces fan power consumption by up to 20% and eliminates the power-sharing board for improved efficiency and lower operation costs.
