3U rackmount chassis with sixteen hot-swap bays

This 3U Supermicro chassis fits standard racks and holds up to sixteen 3.5-inch SAS3 or SATA3 drives on a hot-swap backplane. Redundant 1200-watt Titanium-level power supplies with PMBus support keep the system running if one unit fails. Seven full-height expansion slots accept add-in cards for storage controllers or networking. Motherboards up to 13.68 by 13 inches, including ATX and E-ATX, are supported.

Titanium redundant supply runs cool and quiet

Dual 1200-watt power supplies operate at 96-percent-plus efficiency, reducing waste heat and lowering fan speed under typical loads. PMBus monitoring lets management software track power draw and supply health in real time. The redundant design means a single supply failure does not interrupt operation. Hot-swap drive trays allow drive replacement without powering down the chassis.

Upgrades older 2U or tower storage servers

The sixteen-bay density replaces multiple smaller enclosures or a tower chassis that has run out of drive slots. Builders moving from non-hot-swap backplanes gain tool-less drive service and online capacity expansion. The 205-watt dual-processor support suits workloads that need more compute than a single-socket box provides. Sites without rack infrastructure or that need more than seven expansion slots should consider other form factors.

Questions about this item

How do I install the 16 hot-swap 3.5" drives into the SAS3/SATA3 backplane and what step is often missed?

Slide each drive into a front bay until the carrier locks, then verify both expander links are cabled if the dual-expander option is fitted — the second link is the step most often missed.

Which field-replaceable part will need attention first during long-term operation?

The redundant 1200W Titanium power supply modules are the primary field-replaceable units; fans and the backplane are also serviceable but the PSUs typically reach end-of-life first.

What power ceiling limits sustained full-load operation?

The dual 1200W Titanium units deliver 96%+ efficiency with PMBus monitoring; the 205W processor-support baseline indicates the thermal-power envelope the cooling is designed around.
