iStarUSA Inc. D416-B10SL-SL 4U server chassis, 10 x 3.5" SAS/SATA hot-swap bays

Compact 4U rackmount chassis

The iStarUSA D416-B10SL-SL is a black zinc-coated steel server chassis that fits a standard 19-inch rack in a 4U height. It accepts ATX and microATX motherboards up to 12 by 9.6 inches and provides seven expansion slots for add-in cards. Ten front-accessible hot-swap bays support 3.5-inch SAS and SATA drives for high-density storage. A USB port on the front panel offers convenient local connectivity.

Storage-focused builds, not GPU-heavy nodes

This chassis suits administrators building storage arrays, backup targets or media servers that need many drive bays in a compact rack footprint. The ten hot-swap bays and ATX board support simplify drive maintenance and component upgrades. Builders who require multiple double-width graphics cards or extensive custom liquid-cooling loops should look elsewhere, as the 4U height and seven-slot layout limit card clearance and radiator space.

Ten 3.5-inch SAS/SATA hot-swap bays

The defining specification is the count and interface of the drive bays: ten front-mounted trays that accept 3.5-inch SAS or SATA drives with hot-swap capability. This density determines whether the chassis can meet a given storage capacity target in a single 4U enclosure. Verify that your backplane, controller and cabling match the SAS/SATA interface before ordering.
