  • Intel W790 chipset platform foundation
  • 16 DIMM slots enable large memory capacity
  • 1GbE and 10GbE network ports included
  • 2000W Platinum power supply delivers efficiency

5U barebone for Xeon W-3400

The Supermicro SYS-551A-T is a 5U server barebone built around the Intel W790 chipset and Socket E (LGA4677). It accepts a single Intel Xeon W-3400 processor and provides sixteen DIMM slots for memory expansion. Two power supplies rated at 2000W Platinum deliver redundancy for demanding workloads.

Suited for high-core-count workstations

This platform suits professionals who need a single-socket system with extensive memory capacity and dual-speed networking. Buyers who require multiple processor sockets or a smaller chassis for space-constrained racks should consider a different form factor.

Sixteen DIMM slots define memory ceiling

The sixteen DIMM slots set the maximum memory capacity and channel configuration for the installed Xeon W-3400 processor. This count determines whether the platform can meet the memory footprint of large datasets or simulation tasks.

Questions about this item

Does the barebone include a CPU and memory or do I need to buy them separately?

The unit is a barebone chassis; you must supply a compatible Xeon W-3400 processor and up to 16 DIMM modules yourself.

Which processor socket and chipset does this model use?

It uses a single Socket E LGA4677 paired with the Intel W790 chipset for Xeon W-3400 CPUs.

What network speeds can I expect from the two onboard Ethernet ports?

One port runs at 1GbBaseT and the other at 10GbBaseT, giving you both standard and high-speed wired connectivity.
