Manufacturer Contact Info

The Supermicro AOC-SLG4-2H8M2-O is a PCIe Gen4 x8 hardware RAID card for adding two NVMe or SATA M.2 SSDs to a compatible Supermicro server. It suits server builders who need RAID 0 or RAID 1 storage, with support for 2242, 2280, and 22110 drives.

Recommended For

Administrators of a compatible Supermicro server who want two M.2 drives in a RAID 1 mirror for boot or other data that should remain available if one drive fails.
Supermicro server builders who need to add up to two M.2 SSDs for boot or storage while using a PCIe expansion slot rather than adding more front-bay drives.
IT teams managing supported Supermicro systems that want a hardware RAID card with BMC-enabled management, SuperServer Automation Assistant support, and drive-status LEDs.
Server maintainers who need flexibility to install supported NVMe or SATA M.2 drives and fit 2242, 2280, or 22110 drive lengths.

Real-World Use Scenarios

A server administrator wants the operating system on a mirrored pair of M.2 SSDs. Configuring RAID 1 gives the server a redundant system volume, so a single SSD failure does not automatically mean the volume is lost; recovery and continued operation depend on the server configuration.
An IT team managing a server remotely wants to check the M.2 storage without opening the chassis. With a compatible system, BMC/IPMI management and the card’s drive-status indicators can help administrators identify storage or controller issues during routine maintenance.
A server builder needs a separate M.2 volume for the operating system or hypervisor while keeping other drives available for application data. The card provides two M.2 slots and supports RAID 1, allowing the system volume to be mirrored independently of other storage in the server.
A workstation or server operator wants one M.2 volume for temporary scratch files or rebuildable cache data and prioritizes combining the two drives over redundancy. RAID 0 is supported, but a failure of either SSD can make the array unavailable, so it is a poor fit for the only copy of important data.
