I'm trying to find a PCIe x1 SATA RAID controller, that is supported by ESXi 6.

I've spent hours searching the ESXi compatibility site, however I have yet to come across one. Is this a fruitless search?

  • If its to run on an old motherboard, check if the CPU is fully supported.

  • I am currently looking into same controller, so far I can confirm such device exists - Adaptec RAID 6405E Storage Controller 2270800-R. It is Pci-e x1 and it is supported by ESXi. It is not cheap, though, so I am looking into other options now.

Given that a single sata port is 600MB/s and each PCIe lane can only carry 250MB/s (2.0) or 500MB/s (3.0) its unlikely that anyone would design such a bottlenecked raid card for enterprise.

  • Yup, makes sense. I'll try and move some other cards around and make some room in a different slot.
