Supermicro AOC-SLG4-4E4T-O 4-Port NVMe SSD Low Profile PCIe 4.0 x16 Host Bus Adapter

The Supermicro AOC-SLG4-4E4T-O is a high-performance 4-port NVMe SSD host bus adapter designed for enterprise and data center environments. Leveraging PCI Express 4.0 x16 interface and Broadcom PEX88048 PCIe switch, it delivers up to 64 GB/s theoretical bandwidth, enabling ultra-fast storage for NVMe SSDs (U.2, M.2 via appropriate cables). Its low-profile, half-length form factor fits a wide range of servers and workstations, with both low-profile and full-height brackets included for flexible installation.

Advantages

Unlock the full potential of NVMe storage with four independent SFF-8643 (Mini-SAS HD) internal connectors, each supporting a single NVMe device. Hot-plug support for U.2 drives ensures minimal downtime during maintenance. Bootable NVMe and S.M.A.R.T. monitoring provide reliability and ease of management. Compatible with Windows, Linux, and VMware ESXi, this adapter integrates seamlessly into existing infrastructures.
