Q： Is the A-620 a PCIe M.2 NVMe RAID card (Marvell 88NR2241) with hot-swap capability?
A：The A-620 is a PCIe M.2 NVMe RAID card based on the Marvell 88NR2241 controller chip. The chip itself supports hot plug (Hot Plug / Device Hot Plug) functions in terms of hardware architecture and communication protocol (NVMe-MI).
However, the A-620 is a standard PCIe slot-type M.2 RAID card (does not support online hot-plugging). This is because the A-620 RAID card is inserted directly into the motherboard PCIe slot, and the M.2 SSDs are directly fixed to the card with screws or buckles. Under these circumstances, hot-plugging cannot be performed.
