Gigabyte Barebone R183-Z91-AAV1 Rev. 3.x rack-server 1U dual-socket - barebone - AMD EPYC

Data centers and enterprise IT teams deploying dense virtualization clusters or high-throughput cloud services need a server platform that balances compute density, memory headroom, and storage flexibility without locking into a fixed configuration. The GIGABYTE R183-Z91-AAV1 Rev. 3.x answers that call as a 1U dual-socket barebone built around the AMD EPYC 7001/7002/7003 processor family. With support for up to 280W TDP per socket and 32 DDR4 DIMM slots, this system is ready for memory-hungry workloads like in-memory databases, VDI, and software-defined storage. Eight hot-swap 2.5-inch drive bays, dual 800W Platinum redundant power supplies, and dual 1GbE networking provide a reliable foundation for production environments. Because it ships without CPU, memory, storage, or OS, you retain full control over component selection and lifecycle management.

Key specifications

Why choose it

This barebone puts you in the driver's seat for CPU, memory, and storage choices, so you can tailor the server to exact workload requirements and budget. The dual-socket EPYC design delivers high core counts and massive memory bandwidth, while the 1U chassis maximizes rack density. Redundant Platinum power supplies and hot-swap fans reduce downtime risk, and the dedicated management port simplifies remote administration. GIGABYTE's server engineering ensures compatibility with a wide range of enterprise components, making this a future-ready platform for evolving data center needs.

Ideal use cases

• Virtualization and private cloud infrastructure
• High-performance computing (HPC) and parallel processing
• Software-defined storage and hyperconverged systems
• In-memory databases and real-time analytics
• Enterprise edge computing and micro data centers

Good to know

The server operates reliably between 5°C and 35°C, making it suitable for standard data center environments. As a barebone unit, it requires compatible AMD EPYC processors, DDR4 ECC memory modules, and 2.5-inch SATA/SAS drives to complete the build. The onboard SATA RAID controller covers basic RAID levels without an additional card. For higher network throughput, the two PCIe Gen4 x16 slots can accommodate 10GbE or faster adapters. The IPMI 2.0 management interface with KVM over IP enables full remote control, including BIOS-level access, reducing the need for on-site intervention.
