I screwed that up and posted early. Here’s the context:
I have a Brocade 6610 that I’m getting full on the 8x SFP+ ports so I’m thinking of utilizing the QSFP ports on the back for a 4x 10gb breakout.
I’ve noticed there are DAC cables like below that seem to have transceivers already attached and are the cheap option. All my equipment is in the same rack but I’m using various NICs like the ConnectX-3 and variants of the X520 currently with SFP’s and MM fiber.
As QSFP is “new” to me what I don’t understand is it better to use a DAC cable or buy a QSFP for the brocade and then a MTP to 4 LC cable with the different SFP’s like the other link below?
Seems like the DAC cable is the cheap and quick way to go but I worry about compatibility between the various cards.
What’s the best practice here and recommended approach?
Thanks!
