SKU: OSS-PCIe4-4UP-10-2-1M
Weight: 38 lb

The 10 slot 4U Pro platform provides extreme PCIe Gen4 speed with added professional features. The 4U Pro provides 2 PCIe Gen4 x16 host connections and 8 PCIe Gen4 x16 dual-width expansion slots to support the latest GPUs for AI compute acceleration expansion. The system supports 8 double width GPUs or 10 single slot GPUs or add-in cards (AICs). Dynamic fan speed control keeps the system cool under full load while conserving power and noise when unneeded . Two 1600W power supplies provide redundant hot-swap system power. The semi-rugged frame design and up to 64 GB/s of sustained data throughput make the 10 slot 4U Pro platform ideal for edge AI compute acceleration or converged compute applications.
