2U 12-bay server chassis

The Supermicro CSE-826BE1C-R920LPB is a 2U rack-mountable chassis designed for storage-dense deployments. It accommodates E-ATX motherboards and provides twelve front-accessible drive bays. The unit targets administrators building high-capacity arrays in a compact rack footprint.

Redundant platinum power and hot-swap bays

Two 920 W redundant platinum power supplies with PMBus monitoring deliver continuous operation during a module failure. Twelve 3.5-inch hot-swap SAS/SATA bays connect through a 12 Gbps single-expander backplane with SES3 enclosure management. Three 80 mm PWM fans and seven low-profile expansion slots complete the thermal and I/O layout.

Upgrade from fixed-bay or single-PSU enclosures

The jump is worthwhile when moving from chassis that lack hot-swap capability or redundant power, as both features reduce downtime during drive or supply replacement. Builds requiring full-height expansion cards or more than seven low-profile slots should consider alternative form factors.

Questions about this item

Does the 12Gbps SAS3 backplane cap drive throughput for the 12 hot-swap bays?

The 12-port SAS3 12Gbps single-expander backplane links each 3.5-inch bay at up to 12Gbps, so drive throughput is limited by the SAS3 interface rather than the chassis.

What motherboard sizes fit the 2U chassis with the 3.5-inch height and 17.20-inch width?

The chassis supports ATX 12" x 10", E-ATX 12" x 13", and EE-ATX 13" x 13.68"; with the rear 2.5-inch drive option installed, maximum motherboard size is ATX 12" x 13".

How are the two 1U 920W redundant power supplies installed, and what step is often missed?

Slide each 1U supply into the rear bays until the latch clicks, then connect both PMBus cables to the motherboard so the system can monitor redundancy status.
