Final answer:
The two slots dedicated for NVMe drive installation in a DSS8440 system are M.2 slots and PCIe slots.
Step-by-step explanation:
The two slots dedicated for NVMe drive installation in a DSS8440 system are typically referred to as M.2 slots or PCIe slots.
M.2 slots: These are smaller slots that can accommodate NVMe drives with M.2 form factors. They are usually located on the motherboard of the DSS8440 system. The specific slots may vary depending on the motherboard manufacturer. These slots provide a direct connection to the system's PCIe lanes, allowing for high-speed data transfer.
PCIe slots: These are larger slots that can also accommodate NVMe drives, but they may require the use of an adapter card. PCIe slots are typically used when the DSS8440 system does not have available M.2 slots or when additional NVMe drives need to be installed beyond the available M.2 slots. Like M.2 slots, PCIe slots provide high-speed data transfer capabilities.
