24-bay SAS3 4U rackmount chassis

This 4U rackmount server chassis holds 24 SAS3 drives on a single expander backplane. It supports E-ATX motherboards up to 13.68" x 13.2" and provides seven full-height expansion slots. The enclosure is built for dual-processor configurations rated at 205W each.

Capacity and thermal headroom

The 24-bay backplane handles dense storage arrays without additional cabling. Seven full-height slots accommodate GPU, HBA or networking cards. Ample internal volume allows effective airflow for high-wattage CPUs and add-in cards. The chassis runs out of drive bays at 24 and expansion slots at seven.

Upgrade from smaller direct-attach enclosures

This chassis replaces 2U or tower cases that rely on direct-attach backplanes or limited drive counts. The jump is worth it when a single expander simplifies cabling and dual 205W CPUs are required. It is not for builds needing more than 24 bays or more than seven full-height slots.

Questions about this item

Will my existing E-ATX motherboard measuring 13.68 by 13.2 inches fit in this 4U chassis?

Yes, the chassis supports a maximum E-ATX board of exactly 13.68 by 13.2 inches, so a board of that size will mount correctly.

How can I verify the 24-bay SAS3 backplane and single expander are operating correctly after installation?

The backplane presents 24 drive bays to the host; each bay should report a healthy link speed in your RAID controller or HBA BIOS and the OS should enumerate all attached drives without errors.

Does the package include the 24-bay SAS3 backplane and expander, or must they be purchased separately?

The 24 x SAS3 HDD backplane with single expander is a built-in feature of the chassis, so it ships already installed and no separate purchase is required.
