ASUS RS501A-E12-RS4 LGA 6096 Rack (1U) Black, Silver

Asus RS501A-E12-RS4 is a 1U rack server designed for a single Socket SP5 AMD EPYC 9004/9005 processor (CPU not included). The chassis supports up to 24 DDR5 DIMM modules for a maximum of 2.3 TB memory at up to 6400 MHz, and provides four hot-swap 2.5"/3.5" drive bays plus two M.2 slots. Expansion includes three PCI Express x16 slots and one OCP 3.0 port. Redundant dual 1600 W power supplies with 80 PLUS Titanium efficiency and an Intel I350-AM2 Gigabit LAN controller are built in. The server offers two VGA ports, multiple USB Type-A ports and two RJ-45 Ethernet ports, and is built for standard rack environments with industrial-grade operating and storage ranges.

Advantages

The server combines high memory capacity and DDR5 speeds with a compact 1U rack design, enabling dense compute deployments. Dual redundant 1600 W power supplies with 80 PLUS Titanium certification provide efficient, reliable power delivery. Flexible storage options include hot-swap bays supporting SATA and SAS drives plus M.2 slots for NVMe/SSD configurations. Multiple expansion slots and an OCP 3.0 port allow for networking and accelerator upgrades. Built-in Gigabit Ethernet with a proven Intel controller and a selection of I/O ports simplify connectivity and management.

Suitable for

• Virtualization hosts and dense compute nodes
• Database and in-memory workloads requiring large RAM capacity
• Edge and enterprise rack deployments where 1U density is required
• Storage‑accelerated applications using mixed HDD/SSD and M.2 devices

How to use

Install the server into a standard 19" rack using appropriate mounting rails for a 1U chassis. Populate the Socket SP5 with a compatible AMD EPYC 9004/9005 processor and install memory modules across the 24 DDR5 DIMM slots following the motherboard population rules. Fit storage drives into the hot-swap bays or the M.2 connectors as required, and configure RAID or controller settings in firmware if needed. Connect redundant power feeds to both PSUs, attach network cabling to the RJ-45 ports and configure IP/network settings. Use the VGA and USB ports for local configuration and management; use the OCP slot or PCIe x16 slots for additional NICs or accelerators where required.

Recommendations

For reliable operation, deploy the server in a properly cooled rack environment within the specified operating temperature range and maintain clean airflow by following the chassis ventilation guidelines. Use redundant power connections and UPS protection for critical workloads. Dispose of the product according to local electronic waste regulations.
