4U Rack Server GIGABYTE S453-S70-AAV1 — Dual-socket LGA4677, DDR5, 16 DIMM, 38x 2.5 inch/M.2, 1600W Redundant PSU (80 PLUS Titanium)

GIGABYTE S453-S70-AAV1 is a 4U rack server platform that supports up to two Intel Xeon Scalable Gen 4 processors in LGA4677 (Socket E) sockets and octa-channel DDR5 memory across 16 DIMM slots. The system supports RDIMM speeds up to 5600 MT/s, offers six PCIe Gen5 x16 expansion slots, and provides up to 38 hot-swap 2.5" drive bays plus two M.2 connectors with SATA III, SAS3 and NVMe support. Redundant 1600 W power supplies with 80 PLUS Titanium efficiency and integrated Intel networking provide enterprise-grade reliability and serviceability.

Advantages

The server combines dual-socket processing capability with octa-channel DDR5 memory and high memory density (16 DIMM slots) for compute- and memory-intensive workloads. Six PCIe Gen5 x16 slots enable high-throughput add-in cards for networking, storage or acceleration. High-density storage support with 38 hot-swap 2.5" bays plus M.2, together with redundant 1600 W 80 PLUS Titanium power supplies, supports continuous operation and efficient power delivery. Front and rear USB ports, VGA and COM connectivity and a management LAN simplify installation and maintenance.

Suitable for

• Virtualization hosts and private cloud infrastructure
• Database and in-memory analytics
• Software-defined storage and high-density disk arrays
• AI/ML inference or acceleration appliances with PCIe Gen5 cards
• Enterprise server consolidation and central compute pools

How to use

Install the server into a standard 19" rack using the 4U chassis rails and secure power and network connections. Populate processors, memory modules and storage drives according to vendor guidance for balanced memory channel population and supported drive configurations. Configure RAID or software-defined storage as required, connect management LAN for remote administration and install the desired operating system and drivers that support Intel Xeon Scalable Gen 4 and DDR5 platforms. For hardware changes, follow hot-swap procedures for drive replacement and observe ESD precautions when handling components.

Recommendations

Use enterprise-grade RDIMMs and validated processor models from the Intel Xeon Scalable Gen 4 family. Ensure redundant power supplies are connected to separate sources when available and maintain proper rack airflow for cooling. Handle drive and board replacements while the chassis is properly powered down or following hot-swap guidance to avoid data loss or hardware damage.
