2U Server Chassis with 12Gb/s SAS Expander

This 2U server chassis holds twelve front 3.5-inch drives compatible with 2.5-inch units and three internal 2.5-inch bays. A 12Gb/s SAS expander backplane uses Mini-SAS HD SFF-8643 connections and adds SGPIO signalling plus time-sharing start-up. The enclosure targets cloud storage, big data and security monitoring deployments needing high-density hot-swap storage.

Compatibility Checklist Before Ordering

Verify the motherboard fits the 12-by-13-inch maximum footprint and that the 650mm depth clears your rack rails. Confirm the power supply is a standard 2U or CRPS redundant unit no longer than 300mm. Ensure the host controller presents Mini-SAS HD SFF-8643 ports and supports SGPIO for drive LED management. The chassis provides seven half-height vertical PCIe slots for add-in cards.

Sustained Load Behaviour

Three 8038 ball-bearing fans deliver high static pressure and airflow with hot-swap capability for continuous cooling. Temperature-controlled fan curves adjust speed as drive and component heat rises during long transfers. The 1.0mm SGCC chassis resists fingerprints and aids thermal stability while front drive trays use anti-EMI design with light-guide columns for status indication. Tool-free top cover removal simplifies extended maintenance windows.

Vragen over dit artikel

Does the chassis ship with drives, rails or a power supply, or must I buy them separately?

The unit is an empty chassis; the 12 front 3.5-inch bays and three internal 2.5-inch bays accept drives you supply, and the PSU bay fits any standard 2U or CRPS redundant supply up to 300 mm long.

Should I choose the 12Gb/s SAS expander backplane or a simpler pass-through version for my controller?

The backplane is a 12Gb/s expander with SFF-8643 Mini-SAS HD connectors, SGPIO signalling and time-sharing boot support, so a single HBA can address all 12 bays without extra cabling.

What does the 12Gb/s expander rating mean once the chassis is populated and running?

Each of the 12 bays can run at the full 12Gb/s SAS link speed, and the expander aggregates that traffic over the SFF-8643 uplinks to your controller while SGPIO drives the activity LEDs on every drive tray.
