Questions about this item

Which cable version fits my Dell PowerEdge R640, R740 or R940XA?

The W46M3 is the single part number Dell specifies for all three server models; no other capacity or length variants are listed.

What does the 12Gb/s SAS rating mean once the cable is installed in my server?

It allows each of the eight lanes to move data at up to 12 gigabits per second between the backplane or RAID controller and the attached SATA drives.

What interface standard does this cable use and what speed does it cap at in practice?

It uses the SAS interface rated for 12Gb/s, so the practical throughput limit is 12 gigabits per second per lane when connected to compatible SATA drives.
