Rackmount 3U chassis for dense storage

This 3U rackmount chassis holds sixteen 3.5" hot-swap drive bays and supports E-ATX motherboards up to 13.68" x 13". It ships with a redundant 1000 W Titanium power supply and a SAS3 12 Gbps single-expander backplane connected through four mini-SAS3 HD cables. Seven full-height expansion slots are available for add-in cards.

Verify motherboard size and backplane cabling

Confirm that your motherboard fits the 13.68" x 13" maximum dimension and matches the E-ATX or ATX form factor. The backplane uses four mini-SAS3 HD connectors — two uplink and two downlink — so your controller or HBA must provide compatible ports. Optional 2.5" hot-swap bays are not included unless ordered separately.

Redundant power and five-fan cooling

Two 1U 1000 W Titanium units with PMbus share the load and allow hot-swap replacement without downtime. Five fan positions are supported: three 80x80x38 mm middle fans at 7K RPM and two 80x32 mm rear exhaust fans at 6.7K RPM are included. A PDB with a longer 24-pin connector and dedicated fan-power cables simplify assembly.

Questions about this item

Does the CSE-836BE1C-R1K03B ship with the redundant power supplies and backplane, or must I order them separately?

The package includes the chassis, a SAS3 12 Gbps single-expander backplane with 16 drive slots and four mini-SAS HD connectors, two 1U 1000 W redundant Titanium supplies with PMbus, a PDB, air shroud, front-panel cable, fan extension cable, DVD dummy cover, two 80 mm rear exhaust fans and three 80 mm middle fans.

Which backplane variant fits the CSE-836BE1C-R1K03B — the 16-bay 3.5" SAS3 expander or the optional 2.5" bay add-on?

The standard configuration provides 16 hot-swap 3.5" SAS/SATA bays on a single SAS3 12 Gbps expander backplane; an optional 2 x 2.5" hot-swap bay kit can be added if smaller drives are needed.

What does the 12 Gbps SAS3 backplane rating mean for actual drive throughput in this 3U chassis?

Each of the 16 bays connects through the SAS3 expander at up to 12 Gbps per lane, so SATA SSDs run at their native 6 Gbps while SAS HDDs or SSDs can use the full 12 Gbps link, limited only by the drive and HBA capabilities.
