The Supermicro NVMe AOC-SLG3-4E2P features four internal NVMe connectors (OCuLink) for high-performance storage connectivity. This HBA card is built around a PLX PE9733 PCIe switch IC which is proven NVMe technology with optimum performance for increased bandwidth.. It addresses the growing demand for increased data throughput and scalability requirements across enterprise-class server platforms. This appeals most to embedded/IPC solutions and desk top/gaming solutions that must leverage maximum performance and reliability. Perfect for "near-line cache storage solutions", where data can wait until it gets flushed down to its intended backend storage.
