24-bay 4U rackmount server chassis

This 4U rackmount chassis fits standard motherboards up to 12 by 13 inches and holds twenty-four front-access 3.5-inch drives plus three internal 2.5-inch drives. The SGCC steel construction adds fingerprint resistance while the anti-EMI drive trays include light-guide columns that show each drive’s activity status. Slide rails make hot-swap insertion smooth for storage-heavy workloads.

Expander backplane with Mini-SAS connectors

A 6Gb/s expander backplane uses SFF-8087 Mini-SAS links and supports SGPIO signalling plus time-sharing spin-up to stagger drive start currents. Temperature-controlled fans adjust speed automatically and the two included 12038 ball-bearing fans are hot-swappable. Seven full-height vertical PCIe slots provide rear expansion for RAID controllers or network cards.

ATX or CRPS power with front-panel controls

The chassis accepts a standard ATX supply or a CRPS redundant unit in the 800 to 1500 watt range. Front-panel LEDs cover power, reset, drive activity, dual network, unit identification and overheat or fan-fail alerts. Depth of 650 millimetres requires a deep rack, and the expander topology limits each Mini-SAS port to 6Gb/s aggregate bandwidth.

Domande su questo articolo

What does the 6 Gb/s expander backplane with Mini-SAS SFF-8087 actually limit?

The backplane caps each drive link at 6 Gb/s and aggregates 24 bays through Mini-SAS SFF-8087 cables, so total throughput cannot exceed the combined cable bandwidth.

What motherboard and depth clearances does the 4U chassis require?

It accepts standard boards up to 12" × 13" and fits in a rack with 650 mm usable depth; overall dimensions are 650 mm deep × 437.5 mm wide × 176 mm high.

How are the two included 12038 ball fans installed and what mistake should I avoid?

They mount in the three 12 cm front positions as hot-swappable modules; the common error is leaving the third bay empty without a blanking panel, which breaks front-to-rear airflow.
