The MSI S321 is a 1U dual-socket server barebone for data centers and enterprise IT teams building high-performance systems, with support for 4th- or 5th Gen Intel Xeon Scalable processors, 32 DIMMs, and 12 hybrid NVMe/SATA hot-swap drive bays.
Recommended For
- Cloud service operators building dense rack deployments who need dual Xeon processing, high memory capacity, remote management, and hot-swap storage in a 1U chassis.
- Content-delivery network operators seeking compact rack servers for CDN workloads, with front-accessible hot-swap NVMe storage and out-of-band management.
- Organizations deploying AI inference or fine-tuning services that can use a dual-socket server platform, substantial memory capacity, and multiple high-speed drive bays.
- IT teams assembling customized enterprise servers that want to select their own supported Xeon processors, memory, networking, and storage rather than buy a turnkey system.
