3U 16-bay server chassis

This 3U rackmount chassis fits sixteen front-accessible 3.5-inch drives and three internal 2.5-inch drives. The 12Gb/s Expander backplane uses Mini-sas HD SFF8643 connectors and supports SGPIO and staggered spin-up. It targets cloud storage, big data and security monitoring deployments.

Thermals, noise and power

Three hot-swappable 12038 ball fans provide forced airflow with optional high-pressure variants. The 1.0mm SGCC shell resists fingerprints. A standard 2U or CRPS redundant supply up to 300mm long fits the bay, with 400W to 700W units listed as typical.

Sustained-load behaviour

The expander backplane includes temperature monitoring to regulate fan speed during continuous operation. Seven full-height PCIe slots accept vertical cards for long-running compute or HBA workloads. Front drive trays use anti-EMI guides with LED status columns for ongoing health checks.

Questions about this item

How do I install the 12Gb/s expander backplane with Mini-sas HD SFF8643 cables in this 3U chassis?

Mount the chassis using its 650mm depth and 437.5mm width rails, connect Mini-sas HD SFF8643 cables from your HBA to the backplane ports, then seat the 16 front 3.5in drive trays until the anti-EMI light guide columns click.

Which parts will need replacement first in the 3U 16-disk server chassis?

The three 12038B ball fans are hot-swappable and rated for continuous operation; plan to swap them when bearing noise rises or airflow drops below spec.

What thermal limit appears first when all 16 drives and three fans run sustained loads?

The backplane temperature control triggers fan-speed ramp or overtemperature alert once the 12Gb/s expander or drive bay zone exceeds its internal threshold.
