The high-density 1U 4x GPU SuperServer (SYS-1028GQ-TR/-TRT) maximizes performance and density through pioneering non-preheat GPU architecture and PCIe direct connect (no extension cables, re-drivers, or bridge chips) for lowest latency. It supports up to four NVIDIA Tesla K80 dual-GPU accelerators (up to 300W) or Intel Xeon Phi with a streamlined layout architecture that enables PCI-E direct connect for best signal integrity, as well as elimination of complex cabling, repeaters and GPU pre-heat for maximum airflow and cooling. The system also supports dual Intel Xeon E5-2600 v3 processors (up to 145W), up to 1TB ECC DDR4-2133MHz in 16 DIMM slots, front 2x 2.5” hot-swap SATA drive bays plus 2x 2.5” internal drives, dual 10GBase-T ports and intelligent, redundant 2000W (1+1) Titanium Level high-efficiency power supplies. This architecture allows it to operate at high ambient temperatures.
