Top performance in industry-standard SPEC benchmarksRS500A-E9-PS4 is built on AMD EPYC™ platform to deliver incredible server performance. With up to 32 cores per CPU and up to 64 threads, RS500A-E9-PS4 packs incredible power in minimal space. 16 DIMM slots provide best-in-class memory capacity and bandwidth, and an integrated I/O controller on the processor eliminates the data transfer bottlenecks caused by discrete I/O chipsets for reduced latency and dramatically faster system performance.
Flexible expansion for better storage and networkingRS500A-E9-PS4 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.
RS500A-E9-PS4 fits four 3.5-inch hot-swappable 12Gbps SAS or 6Gbps SATA drives. One M.2 slot 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 efficiencyRS500A-E9-PS4 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 centers with extreme workloads.
Comprehensive IT Infrastructure ManagementRS500A-E9-PS4 features an embedded iKVM module and is bundled with ASUS Control Center 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 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 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 connectorASUS 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
Platinum PSU supportRS500A-E9-PS4 supports 650W 80 Plus Platinum power supply, which are 96%+ efficient, directly reducing operating costs and capital expenses.
Quick initialization guidanceRS500A-E9-PS4 provides instant system information during initialization and reports any unusual diagnostic results for more efficient IT operation and easy troubleshooting.
Visible Q-CodeRS500A-E9-PS4 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 debuggingAn 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 supportA BMC (baseboard management controller) supports microSD cards to facilitate remote OS updates, image file and video storage, and log data tracking.
