| X9 platform era | Approx. 2012–2014 | X9DR, X9S, early SuperServer and SuperStorage systems | Xeon E5-2600 v1/v2 and related platforms, DDR3, SATA/SAS storage options | The exact chassis, board, processor, drive backplane, and node count determine whether the system is worth evaluating as a complete unit or for parts. |
|---|
| X10 platform era | Approx. 2014–2017 | X10DR, X10SR, 1U/2U SuperServer and SuperStorage platforms | Xeon E5-2600 v3/v4 and related platforms, DDR4, expanded SAS, PCIe, and NVMe options | Photograph both the chassis and motherboard labels; a generic 2U SuperServer description leaves out the details buyers need. |
|---|
| X11 platform era | Approx. 2017–2020 | X11DP, X11SP, Twin and BigTwin systems | Xeon Scalable 1st/2nd Gen, Xeon E, and related platforms, DDR4, NVMe and multi-node options | For Twin and BigTwin systems, list every node, node CPU and memory, shared power supplies, backplane, and included rails. |
|---|
| X12 platform era | Approx. 2020–2022 | X12DP, X12SP, SuperStorage and GPU-capable systems | 3rd Gen Xeon Scalable and AMD EPYC 7003 options, DDR4, PCIe Gen4, NVMe, and accelerator support | GPU, storage, riser, and power configurations can change value substantially; list the exact board and chassis combination. |
|---|
| X13 platform era | Approx. 2022–2024 | X13DP, X13DE, X13SAE, GPU and high-density platforms | 4th/5th Gen Xeon Scalable and AMD EPYC 9004 options, DDR5, PCIe Gen5, and current accelerator layouts | Include GPU model, quantity, risers, power cables, cooling fans, and the motherboard revision for accelerated systems. |
|---|
| Newer platform families | Approx. 2024–present, model-dependent | Current Xeon 6, AMD EPYC, AI, storage, and multi-node platforms | Model-specific DDR5, PCIe Gen5, high-speed networking, NVMe, and accelerator capabilities | Use the chassis and board identifiers as the source of truth; Supermicro product families can overlap by CPU platform and workload. |
