Top performance in industry-standard SPEC benchmarks
RS500-E9-RS4 supports two of the latest Intel Xeon Scalable Family processors, which feature up to 56 cores and 112 threads and operate at a maximum of 205W for leading performance. It also has 16 memory slots that fit up to 2TB of DDR4 2666 for memory-intensive computing.
Flexible expansion for better storage and networking
RS500-E9-RS4 features one PCIe x16 and one PCIe x8 slots to deliver parallel computing power and one OCP 2.0 Mezzanine connector to support high-speed LAN card. This flexibility supports diverse storage and networking applications and ensures future expandability and high scalability in a 1U server.
RS500-E9-RS4 fits four 3.5-inch hot-swappable 12Gbps SAS or 6Gbps SATA drives. Two M.2 slots accommodate 22110-size SSDs with support for additional OS storage and PCIe Gen3 x4 bandwidth — 5.3X faster than 6 Gb/s SATA III — for faster boot speeds.
Exclusive Thermal Radar technology for energy efficiency
RS500-E9-RS4 features ASUS-exclusive Thermal Radar technology with ambient sensors placed in CPU, memory, NVMe, SSD, OCP mezzanine connector for internal and external temperature monitoring, and dynamic fan-curve adjustment, which lowers fan power consumption by up to 20% and reduces total cost of ownership — ideal for data centres with extreme workloads.
Exclusive Performance Boost technology
ASUS features exclusive Performance Boost technology to achieve peak server performance and agility by tuning servers to match the requirements of workloads, letting you gain greater control of your server environment. This technology improves workload throughput by maximising processor frequency and boost power, ideal for time-sensitive applications such as financial services or data centre operations.
Redundant Platinum PSU support
RS500-E9-RS4 supports redundant 770W 80 Plus Platinum and 450W 80 Plus Gold power supplies, which are 96%+ efficient, directly reducing operating costs and capital expenses. The 1+1 power-supply design allows the server to keep working even if one power supply requires maintenance, enabling uninterrupted operation.
Comprehensive IT infrastructure management
RS500-E9-RS4 features an embedded iKVM module and is bundled with ASUS Control Centre to provide comprehensive out-of-band and in-band management features for small and mid-size businesses.
The embedded ASMB9-iKVM module supports remote BIOS updates, fan control, standalone KVMs, video recording, and BSOD capture, providing around-the-clock remote monitoring and diagnostics — even if the operating system is down or offline — through a user-friendly, web-based graphical interface that works with all major browsers.
ASUS Control Centre (ACC) is a centralised and integrated IT management platform for monitoring and controlling ASUS commercial products, including servers, workstations and digital signage. ACC enables remote BIOS updates, monitoring of multiple systems via mobile devices, and one-click software updates and dispatching, allowing easier server management for any IT infrastructure.
ASUS ProCool connector
ASUS ProCool power connectors are designed without any hollow areas, enabling lower impedance, faster heat dissipation and cooler operating temperatures for reduced power loss and increased cost savings.
Quick initialisation guidance
RS500-E9-RS4 provides instant system information during initialisation and reports any unusual diagnostic results for more efficient IT operation and easy troubleshooting.
RS500-E9-RS4 has a visible Q-Code/port 80 LED display for simple monitoring of the entire boot process, from power on through loading of the operating system.
OS drive installation and debugging
An internal USB 3.0 port accepts boot disks, providing a safer way to install Linux or VMware Hypervisor as well as additional access for debugging.
MicroSD card support
A BMC (baseboard management controller) supports microSD cards to facilitate remote OS updates, image file and video storage, and log data tracking.
