FX100 · FX200 · FX300 · FX400
The FX series consists of all-flash NVMe-oF arrays designed as the third KV cache tier for LLM inference, developed on Guangdong Luisuan GP-series hardware and delivered with a vLLM + LMCache stack. Specifications below are vendor figures; models with measured reports are marked.

FX100In production
FX100 has the most complete benchmark record in the FX series: it is the device under test in R1–R5 and R9, across AMD MI308X, MetaX N260 and Huawei Ascend 910B. It offers 100 Gb per port and 16M IOPS, and is sized at one array per 8 inference nodes in production.
FX200In production
FX200 raises the per-port rate to 200 Gb and IOPS to 32M, twice the FX100 figures. Its 6 PCIe expansion slots accept a mix of ASIC, FPGA and DPU cards, which suits clusters that need more bandwidth per port or bring their own accelerator cards.
FX300In production
FX300 is the performance tier on PCIe 5.0: 400 Gb per port and 60M IOPS, with 6 DPUs and Gen5 enterprise NVMe SSDs, aimed at high-concurrency KV read-back and fast distribution of large model weights.
FX400Test units; volume production planned for late 2026
FX400 is the next flagship: a PCIe 6.0 platform with E1.S flash, specified by the vendor at 4.8 Tb/s aggregate bandwidth and 140M IOPS. Test units were scheduled for August 2026, with volume production planned for late 2026; the specifications will be backfilled with test-unit measurements, and production pricing has not been announced.
| Platform (without drives) | ¥160,000 | |
|---|---|---|
| Enterprise NVMe SSDs | 24 × ¥8,800 | ¥211,200 |
| FX100 fully populated reference price | 184.3 TB · ≈¥2,014/TB | ¥371,200 |
Fully populated reference price = platform ¥160,000 + 24 × ¥8,800 = ¥371,200 for 184.3 TB raw, about ¥2,014 per TB. SSDs are counted at a reference market price that moves with the market; the purchase contract sets the final price.
A note on names: in earlier test-report filenames FX100 appears as AISSD5000, and before that as WS5000 / GP5000; some reports are signed “Mingxin”. They all refer to the same product. This site uses the FX naming throughout (FX100 / FX200 / FX300 / FX400), while report entries keep their original titles so you can cross-check.
Test jointly first, decide afterwards
Every engagement starts with a gated joint test of about 10 weeks. Four gates are passed in sequence; if one is missed, the project stops there, so you never pay for a benefit that was not demonstrated.
