The Supermicro MegaRAID Low Profile AOC-SLG4-2H8M2 is an M.2 SSD carrier card that enables the user to add up to two NVMe or SATA M.2 SSDs to any X11, X12, X13, H11, or H12 motherboard. M.2 solid state technology is an optimized, high-performance, scalable storage solution, effectively streamlined for enterprise and client systems that leverage the cutting-edge power of PCI Express.
AOC-SLG4-2H8M2 supports adjustable stand-offs in 22110, 2280 and 2242 M.2 SSD with RAID 0 and RAID 1.
Product Note:
AOC-SLG4-2H8M2, as a Gen 4 NVMe M.2 adapter, a uniquely designed heatsink.While adopting 22x110mm M.2s, it is suggested to ONLY select the M.2s qualified by referencing each system's AVL with AOC-SLG4-2H8M2.
AOC-SLG4-2H8M2 carries SAS 3808 chipset, a 12Gb/s SAS/SATA controller. Thus NVMe M.2s populated on the carrier are exposed with SAS addresses and recognized as SATA devices or SAS drives by OS or BIOS.
When a system with IOMMU or VT-d enabled is configured with an iMR controller-based storage add-on-card/module, please make sure the system BIOS supports either IVMD (AMD-based system) or RMRR (Intel-based system) for iMR controller to work seamlessly with host memory.
Also see statements from Broadcom in its user guide, section “HII Configuration Utility”.
AOC-SLG4-2H8M2 supports both SATA/NVMe M.2. With StorCLI cmd "storcli /call show all" executed, it should report the follows on slot numbering: #0 and #4 for SATA M.2 #0 and #1 for NVMe M.2
To build VD (virtual drive) / RAID, state of the drives in RAID volume must be "Unconfigured Good'.
Users can force and disable "JBOD" mode and change drive state to "Unconfigured Good" for M.2s installed on AOC-SLG4-2H8M2 by executing the following StorCLI command. storcli /cx/ex/sx set good force
To enable/disable "JBOD Mode" for AOC-SLG4-2H8M2 or on any of the SAS 3816/3808 based controller AOC, you can either:
executing the StorCLI commands below; or storcli /cx set JBOD=on storcli /cx set JBOD=off
operating through BMC IPMI WebGUI > Storage Monitoring > Controller View > Enable JBOD; or
