2U barebone with 24 NVMe bays

This 2U rackmount barebone server supports dual AMD EPYC 9005 and 9004 series processors in Socket SP5. It provides 24 DDR5 4800 memory slots with a maximum capacity of 6 TB. The chassis includes 24 hot-swap 2.5-inch NVMe bays and two fixed NVMe bays, all running at PCIe 5.0 x4. Redundant 2600 W CRPS power supplies with 80-PLUS Titanium efficiency are integrated.

Suits dense storage compute.

The system targets general-purpose deployments that need high local NVMe density and dual-socket CPU performance. Expansion is limited to three rear PCIe 5.0 slots and one OCP NIC 3.0 slot, all full-height or half-height. There are no additional full-length double-width GPU slots, so buyers needing multiple accelerator cards should look at a different platform.

24 hot-swap NVMe bays define the storage ceiling

The single specification that decides fit is the 24 front-accessible hot-swap 2.5-inch NVMe bays operating at PCIe 5.0 x4. This count sets the maximum number of removable drives without adding external enclosures. If the workload requires more than 24 hot-swap NVMe devices, this barebone cannot meet that requirement.

Questions about this item

Does the barebone include CPUs, memory or drives, or must they be purchased separately?

No CPU, memory or storage is installed; you must supply two SP5 processors, DDR5 4800 RDIMMs up to 6 TB and NVMe drives for the 24 hot-swap plus 2 fixed 2.5" bays.

Which AMD EPYC series does the SP5 socket support?

The dual SP5 sockets support EPYC 9004 and 9005 series processors, including 97x4 models and parts with 3D V-Cache technology.

What bandwidth does each of the 24 hot-swap NVMe bays deliver to the CPU?

Every hot-swap bay is wired for PCIe 5.0 x4, giving each drive a full Gen 5 four-lane link to the processor.
