Choose the DVA1622 for a compact, lower-cost deployment: it uses a Celeron J4125, supports up to 6GB RAM, has two bays expandable to 16, and includes M.2 NVMe slots but no 10GbE. Choose the DVA3219 for heavier workloads: its Xeon D-1521, 32GB RAM ceiling, four bays expandable to seven, and built-in 10GbE offer substantially more headroom, though it lacks M.2 slots.
