GIGABYTE 2U barebone with 12 front bays

The GIGABYTE R283-S90-AAE3 is a 2U rackmount server barebone designed for general-purpose workloads. It arrives without CPUs, memory or storage so integrators can configure the platform to exact requirements. Dual LGA 4677 sockets support two processors with up to 350 W TDP each. The Intel C741 chipset provides 8-channel DDR5 across 32 DIMM slots.

Suits dual-socket builds needing dense NVMe capacity

This platform fits organisations deploying dual 4th or 5th Generation Intel Xeon Scalable or Xeon CPU Max Series processors with high memory counts and local flash storage. It does not suit single-socket deployments, towers or edge sites that need integrated graphics beyond the Aspeed AST2600 management controller. Buyers who want more than 12 front drive bays or more than five full-height PCIe Gen5 x16 slots should evaluate larger form factors.

12 front hot-swap bays with Gen4 NVMe support

The chassis provides 12 x 3.5"/2.5" hot-swap bays that accept Gen4 NVMe, SATA or SAS drives, plus two additional 2.5" rear bays for SATA or SAS. This bay count and protocol mix is the primary factor when matching the system to storage-intensive workloads such as software-defined storage or database clusters.

Questions about this item

How do I install the CPUs into the LGA 4677 sockets, and which step is most often done incorrectly?

Align each processor using the socket notches, lower the load plate, then torque the retention screws in a diagonal sequence; skipping the diagonal pattern leaves uneven pressure and causes boot failures.

Which components will need replacement first during long-term operation?

The Aspeed AST2600 management controller and the hot-swap drive backplanes are the only active parts not covered by the dual-processor design; plan to replace a failed backplane or BMC module before the CPUs or memory.

What limit appears first when the system runs sustained workloads at the 350W TDP per socket?

Thermal headroom in the 2U chassis becomes the bottleneck; the front 12-bay NVMe backplane and rear 2.5-inch bays restrict airflow, so CPU throttling occurs before power or memory bandwidth limits are reached.
