24-Bay 4U Storage Server Chassis

This 4U rackmount chassis provides 24 hot-swappable 3.5-inch drive bays plus four 2.5-inch bays. It targets builders deploying high-density storage servers for IPFS nodes, backup targets or media libraries. The 6Gb/s miniSAS backplane supports both Sata and SAS drives. Three 12038 fans deliver front-to-rear airflow.

Capacity and Headroom

Twenty-four 3.5-inch bays allow raw capacities into the hundreds of terabytes with current drives. Two internal and two rear 2.5-inch bays host OS or cache SSDs. The backplane includes time-sharing spin-up to limit inrush current. Seven full-height PCIe slots accommodate HBA or RAID controllers. Maximum motherboard size is 12 by 10.5 inches.

6Gb/s miniSAS Backplane Limits

The standard backplane runs at 6Gb/s per lane, capping sequential throughput per drive at that rate. An optional 12Gb/s version lifts the ceiling for SAS SSDs. Expander support lets one HBA address all bays, but total bandwidth remains bound by the HBA link width. PWM fan control and SGPIO status LEDs are integrated.

Questions about this item

Will this 4U chassis with 24 hot-swappable 3.5-inch bays fit my existing 12-inch deep motherboard and standard 2U power supply?

Yes, the chassis accepts motherboards up to 12 by 10.5 inches and supports standard 2U, PS2 and CRPS redundant power supplies.

How can I verify the 6Gb/s miniSAS backplane and drive status LEDs are functioning after installation?

The backplane provides SGPIO signalling so drive activity and fault LEDs on the front panel light automatically when drives are accessed.

Which drives, rails and fans are included with the empty chassis and what must I source separately?

The unit ships with three 12038 fans installed; you must supply all 3.5-inch or 2.5-inch drives, mounting rails and a compatible power supply.
