SuperMicro: SYS-4028GR-TXRT (NVLink)
2S + 24DIMM, CPUs with
active heat dissipation
2*PCIe x8 slots
The CPUs provide 2*PCIe x8, which
are alternatively supported with the
hard drive RAID and NVMe.

Beating Points
• The 8 NVMe SSDs are restricted by the PCIe x8 links, and only two drives support line
rate.
• The power supply capability is limited and cannot be evolved.
• Active heat dissipation for the CPUs (many failure points)
• The power module is integrated into the fan and has to be inserted and removed at the
same time during maintenance, which makes maintenance inconvenient.
