Someone asked earlier whether it would be possible to direct connect two systems with 10GbE CX4 ports here: is it possible to direct connect a client and server with 10GBASE CX4 copper cables?.
My question is the same, but with the SPF+ ports. I assume this would work, but before ordering the pricey interconnect cable, I thought of confirming whether it is at least likely that it will work.
Yes, make sure you're getting SPF+ direct connects and that your cards support that configuration.
Some exclusions apply. See dealer for complete rules, full details, and restriction. Your millage may vary. Slippery when wet.
