ASUS RS521A-E12-RS24U Socket SP5 Rack (2U) μαύρο, ασημί

Asus RS521A-E12-RS24U is a 2U rackmount server platform supporting AMD EPYC 9005 processors in Socket SP5 with an integrated CPU option. The chassis accommodates up to 24 DDR5 DIMMs (maximum 2.3 TB) with RDIMM support up to 5200 MHz, and provides enterprise features such as 12 hot-swap 3.5" drive bays, two M.2 slots and five PCIe x16 expansion slots. Network connectivity is delivered by dual Gigabit Ethernet ports driven by an Intel I350-AM2 controller. The system includes redundant dual 2000 W power supplies with 80 PLUS Titanium efficiency and a silver 2U rack chassis designed for data centre deployment.

Advantages

The server combines high memory capacity and DDR5 performance with a dense storage layout and multiple expansion options, enabling virtualization and storage-heavy workloads. Redundant 2000 W power supplies with 80 PLUS Titanium certification increase power efficiency and availability. Hot-swap 3.5" bays and enterprise network controller support maintenance and connectivity requirements typical for rack deployments.

Suitable for

• Virtualization and hyperconverged infrastructure
• Storage-dense applications and archival servers
• High-performance compute clusters and database servers
• Enterprise data centre rack deployments

How to use

Install the server into a standard 19" rack using appropriate rails for a 2U chassis. Populate memory modules across the 24 DIMM slots following the motherboard channel and population guidelines to achieve the intended performance and capacity. Mount 3.5" drives into the hot-swap bays or install M.2 SSDs into the M.2 slots, and connect storage using SATA or SAS as required. Connect redundant power supplies to separate power circuits for fault tolerance. Configure networking via the onboard Gigabit Ethernet ports and install additional expansion cards into the PCIe x16 slots if needed. Follow standard server setup procedures for BIOS/firmware configuration and operating system installation.

Recommendations

For reliable operation in data centre environments, run the server within the specified operating temperature (10–35 °C) and humidity (20–90% for storage). Use RDIMM modules validated for DDR5 5200 MHz and populate memory channels evenly. Connect both power supplies to independent circuits to maintain redundancy and perform hot-swap drive replacement only when the drive activity indicators show idle.
