A 6U rackmount server chassis holding sixty 3.5" hot-swap bays with a 12Gb/s expander backplane
This 6U rackmount server chassis provides 60 hot-swappable 3.5-inch drive bays plus two internal 2.5-inch bays, delivering high-density storage in a standard 19-inch rack footprint. The 12Gb/s expander backplane uses Mini-SAS HD (SFF-8643) connectivity for SAS and Sata drives. It suits organisations building dense storage nodes for cloud, big data or surveillance workloads.
The design fits E-ATX and EE-ATX motherboards up to 13.68 by 13 inches and offers seven half-height PCIe expansion slots for controllers or networking cards. Cooling is handled by six hot-swap 12038 fans plus four 8038 fans, all mounted in a 1.0 mm SGCC steel frame with anti-EMI drive drawers. Builds needing full-height cards, more than seven slots, or a backplane interface other than 12Gb/s or 6Gb/s SAS/Sata will not match this platform.
The single specification that determines fit is the 12Gb/s expander backplane with Mini-SAS HD (SFF-8643) ports, which sets the drive interface speed and cabling for all 60 hot-swap bays. If the host controller or cabling uses a different interface or speed, the chassis cannot operate as intended.

The chassis uses six 12038 and four 8038 ball-bearing fans; plan a visual check every six months and replace any unit that shows bearing noise or reduced airflow.
The 12Gb/s expander backplane with its temperature-control chipset will hit its sustained-throughput limit before the SGCC steel structure or the CRPS power supplies become a bottleneck.
Ten high-speed ball fans move large air volumes through the 650 mm depth, so expect noticeable fan noise and a steady exhaust temperature that the backplane's temperature-control chipset actively monitors.
