2U 12-Bay SAS/SATA Server Chassis

The HOTCFWQ chassis is a 2U rackmount enclosure built for twelve 3.5-inch hot-swap drives. It fits a standard 19-inch rack and accepts motherboards up to 12 by 13 inches. A 6Gb/s backplane with a temperature control chipset handles both SATA and SAS drives. Redundant power supply support is included for higher availability.

Suits storage-heavy 2U deployments

This chassis suits builders who need dense 3.5-inch storage in a 2U form factor with hot-swap access and redundant power. It is not for buyers who need more than twelve drive bays. It is not for systems that require 2.5-inch drive support or a deeper rackmount depth than 650mm. The three included 8038 ball-bearing fans provide baseline airflow; a fourth fan position is optional.

6Gb/s backplane with temperature control

The deciding specification is the 6Gb/s SAS/SATA backplane that includes a temperature control chipset. It connects twelve hot-swap bays through Mini SAS or expander options while monitoring drive thermals. This backplane speed and monitoring combination determines whether the chassis matches your controller and drive requirements.

Questions about this item

Will the 12 x 3.5" hot-swap bays fit in a standard 19" rack?

Yes, the chassis measures 437.5 mm wide and 88 mm high, matching a standard 19" 2U rackmount footprint.

How do I install the 3 pcs 8038 ball bearing fans and what step is often missed?

Mount the three included 8038 fans in the front fan wall, then connect each fan header to the backplane's temperature control chipset so speed ramps with drive heat.

When should I replace the 8038 ball bearing fans in this chassis?

Replace any 8038 fan that develops bearing noise, vibration, or triggers the OH/FAN Fail LED on the front panel.
