Today we are taking a look at one of the largest single systems STH has ever reviewed. The Supermicro 4028GR-TR GPU SuperServer houses up to 8x GPU/Xeon Phi, dual Xeon E5 processors and 24x 2.5” drive bays all in a single 4U chassis. Recently we reviewed one of Supermicro GPU/Xeon Phi SuperServers, namely the 1028GQ-TRT which is equipped with 4x AMD FirePro S9150’s in a compact 1U server case. See our Supermicro 1028GQ-TRT Quad GPU 1U SuperServer Review. This is essentially this is the larger sibling.
