WHY CHOOSE THIS PRODUCT?

• 834978-B22 is suited to buyers extending or replacing an existing Mellanox EDR InfiniBand fabric who need 36 managed 100Gb/s ports, high switching capacity and redundant hot-swappable components in a power-side-inlet configuration. Its managed architecture differentiates it from the unmanaged 834976-B22, while the power-side airflow separates it from the RAF 834979-B22, making exact fabric, rack-airflow and management requirements important procurement checks. HPE continues to publish switch-management software information for this specific part, supporting lifecycle maintenance for compatible deployments.
