1U Rack Supermicro SuperServer SYS-511R-M barebone server, Intel C266 chipset, LGA 1700, DDR5 up to 128 GB, SAS/PCIe storage, Gigabit Ethernet

Supermicro SuperServer SYS-511R-M is a 1U rack barebone server based on the Intel C266 chipset with an LGA 1700 socket. The chassis supports a single processor, up to four DDR5 DIMMs for a maximum of 128 GB memory, and up to four 3.5" hot-swap drive bays compatible with SAS or PCIe storage. Network connectivity includes dual Gigabit Ethernet ports (Intel I210) and multiple USB ports. The unit is supplied with a 600 W power supply and a black rack-friendly chassis.

Advantages

The SYS-511R-M combines a compact 1U form factor with flexible storage and memory capacity, making it suitable for dense rack deployments. Support for DDR5 memory up to 128 GB and hardware RAID levels 0/1/5/10 provides performance and data protection options. Hot-swap 3.5" bays simplify drive maintenance and replacements without system downtime.

Suitable for

• Virtualization hosts and lightweight hypervisor nodes
• Storage nodes or small-scale NAS using SAS/PCIe drives
• Edge and compact rack deployments requiring 1U density
• Small business servers for file, backup or application hosting

When it may not be suitable

This barebone server supports a single processor and a maximum of four DIMM slots, so it may not meet requirements for very high CPU core counts or memory-dense workloads that need more than 128 GB. The 1U chassis limits large air-cooled CPU coolers and may restrict expansion card height compared with larger form factors.

Key specifications

• Form factor: 1U rack chassis
• Chipset: Intel C266
• CPU socket: LGA 1700 (single-socket support)
• Memory: 4 DIMM slots, DDR5 up to 128 GB (RDIMM support, speeds up to 4400 MHz)
• Storage bays: 4 × 3.5" hot-swap drive bays (SAS/PCIe compatible)
• RAID: Hardware RAID 0/1/5/10 supported
• Network: 2 × Gigabit Ethernet (Intel I210)
• USB: Multiple USB ports (including USB 2.0)
• Power supply: 600 W
• Color: Black

How to use

Install a compatible LGA 1700 processor and populate up to four DDR5 DIMMs according to the motherboard manual. Mount the server in a standard 19" rack using the included rails or brackets. Insert SAS or PCIe 3.5" drives into the hot-swap bays and configure hardware RAID through the controller firmware or BIOS utilities. Connect network and power cables, then install your preferred operating system or hypervisor and configure services as required.

What to consider before purchase

• Confirm required CPU compatibility with LGA 1700 and supported processor families
• Plan memory needs within the 4 DIMM / 128 GB limitation
• Verify drive interface compatibility (SAS or PCIe) for your storage devices
• Ensure a suitable rack environment for 1U cooling and airflow
• Check expansion and accessory compatibility for RAID controller and network options

Usage recommendations

For best results use enterprise-grade SAS or NVMe drives supported by the server's backplane and configure redundant RAID levels for data protection. Maintain proper rack airflow and monitor power and thermal metrics when populating the chassis to maximum capacity.
