Review on ๐Ÿ’ป Enhanced Macroreer HP JD097C X240 10G SFP+ Direct Attach Copper Twinax Passive Cable - 3-Meter (9.9ft) by John Larsen

Revainrating 5 out of 5

WORKS for my Aruba S2500-48p switch!

I was struggling to find a DAC that would work with my Aruba S2500-48p switch, but this one worked great! However, you CAN get an unsupported SFP+ error when connecting this DAC to a picky Intel card. This is not a cable error, but rather a wrong decision by Intel to only allow Intel SFPs. I was able to use a kernel mod to force RHEL7 and RHEL8 to ignore the error from the NIC and use SFP. I'm getting damn close to the full 10 Gb/s with this cable. Love it!
