Why consider this model?

  • A shortlist candidate for an enterprise rack team that needs a 16-position NAS/SAN platform with QES, active-active controllers and built-in 10GbE, and can separately provision compatible drives, network paths, rack infrastructure and operational support.

Tradeoffs to weigh

  • This is a 3U enterprise array, not a compact plug-and-play NAS. Drive models are not included, the exact dynamic compatibility rows were not captured, and rack depth, weight, power/heat, SFP+ equipment, QES administration, configuration suffix and seller terms need deliberate verification.
