## Summary description

The Supermicro AOC-SMG3-2M2-B-O is a RAID controller that supports PCI Express 4.0 and M.2 storage interfaces. It offers RAID levels 0 and 1, providing flexibility for data management and redundancy. Ideal for enhancing storage performance in server environments.

## Long description

The Supermicro AOC-SMG3-2M2-B-O is a compact PCIe 4.0 M.2 RAID carrier riser card designed to hold two M-key M.2 NVMe SSDs. It integrates a hardware RAID controller that supports RAID 0 and RAID 1, providing the option for increased performance or mirrored redundancy for operating system drives and other critical storage. The card is intended for server and workstation environments where space is limited and OS reliability is important.
Advantages
The AOC-SMG3-2M2-B-O offers hardware RAID1 support to mirror two NVMe M.2 drives, adding an extra layer of redundancy without relying on host software. Its PCIe 4.0 compatibility enables high-bandwidth access to NVMe SSDs, and the compact riser form factor saves motherboard or chassis space while allowing installation of two M.2 drives on a single card.
Suitable for
 Server operating system boot drives
 Compact workstations requiring NVMe redundancy
 Edge or appliance systems with limited internal bays
 Environments needing low-overhead hardware RAID for OS disks
Key specifications
 Model: Supermicro AOC-SMG3-2M2-B-O
 Interface: PCI Express 4.0
 Drive connectors: 2 × M-key M.2 NVMe
 RAID levels supported: 0, 1 (hardware RAID)
 Use case: OS and critical NVMe storage
How to use
Install the riser card into an appropriate PCIe x16/x8 slot following the server or motherboard manual. Mount two M.2 NVMe drives into the M-key slots and secure them with the provided standoffs or screws. Configure the RAID level (RAID0 or RAID1) via the card's management interface or firmware during system boot according to Supermicro's setup instructions, then proceed to install the operating system or restore data to the virtual drive presented by the controller.
Usage recommendations
For OS reliability, use matched-capacity NVMe SSDs and enable RAID1 for mirror protection. Ensure firmware and BIOS are up to date and verify compatibility with your server motherboard and PCIe slot to achieve full PCIe 4.0 performance.
