This KALEA INFORMATIQUE controller board (PI6CB33402) is a high-speed expansion solution designed to accommodate up to four M.2 NVMe SSDs (with M key format) of different lengths (2280, 2260, 2242, 2230). It connects to the PCI Express 5.0 x16 slot of the motherboard, providing a total mass theoretical bandwidth up to 64 GB/s . The card supports the PCIe bifurcation, which is essential for the BIOS to divide the x16 slot into four separate x4 lines, each dedicated to an SSD. It is backward compatible with PCIe 4.0 and 3.0 standards. The inclusion of low profile bracket (low profile) allows installation in both standard and compact server systems. Main technical specifications Host interface: PCI Express (PCIe) 5.0 x16. SSD support: 4 x M.2 NVMe (Key M). Form factors M.2: 2280, 2260, 2242, 2230. Maximum Teorica Band: 64 GB/s (PCIe 5.0 x16). Main Chipset: Integrates the PI6CB33402 buffer clock for Gen 5.0 compatibility. Retrocompatibility: Fully compatible with slots and PCIe 4.0 and 3.0 standards. Request function: Requires support of the Bifurcation x4/x4/x4/x4 function by the motherboard and BIOS. Accessories: Provided with Low Profile bracket and standard bracket. Speed Link For SSD: Each SSD operates on PCIe x4 (with active bifurcation). SSD Type Supported: NVMe SSD Only (not SATA M.2).
