2U 12-Bay SAS Chassis

This 2U rackmount server chassis holds twelve 3.5-inch hot-swap drive bays and fits a standard 19-inch rack. It is built from 1.0 mm SGCC zinc-coated steel and supports motherboards up to 12 by 10.5 inches. The unit targets storage-heavy workloads such as cloud storage, big data and security monitoring. A 550 W redundant power supply is included for continuous operation.

Installation and common issues

The chassis slides into a 19-inch rack using the 437.5 mm width and 88 mm height, then secures with rack screws. Drives insert tool-free into the twelve hot-swap bays that accept SATA and SAS drives. The backplane uses Mini SAS connectors and includes a temperature control chipset. Builders must supply four 8 cm fans themselves because only three 8038 ball-bearing fans are fitted as standard. The seven full-height expansion slots require careful cable routing to avoid airflow blockage.

Interface and capacity limits

Each drive bay runs at 6 Gb/s for both SATA and SAS protocols despite the 12 Gb/s Mini SAS backplane rating. The front panel provides two USB 2.0 ports with an optional USB 3.0 upgrade not fitted by default. The 550 W redundant supply caps total system power, so high-wattage CPUs or many add-in cards may exceed the budget. Seven PCIe slots are available but the 560 mm depth restricts card length.

Questions about this item

How do I verify the 12Gb/s SAS backplane is operating correctly after installation?

Check that the temperature control chipset on the backplane reports normal readings, confirm all 12 drive bays show active LEDs, and ensure the OH/FAN Fail and Power Fail indicators remain off.

What ships with the chassis and what must I source separately?

The chassis includes the 12Gb/s MINI SAS backplane, three 8038 ball-bearing fans, a 550W redundant PSU, and two front USB 2.0 ports; motherboard, drives, and any USB 3.0 upgrade are not included.

Which backplane version should I choose for 12Gb/s SAS drives?

Select the 12Gb/s MINI SAS backplane with temperature control chipset; the 6Gb/s SATA or 6Gb/s MINI SAS options do not support the full 12Gb/s SAS speed.
