Thank you both. We are considering HP's "X240 10G SFP+ SFP+ 5m" DAC cable to connect HP 5900 switch.

Hi OzenZ,

how far did you get? Did you get any information HP's X240 is supported?

We use DAC cables with Extreme switches and with procurve switches with no problems.

isi_cat the link you posted is not a public resource, I believe it is internal to EMC / Isilon Professional services?

Hello,

I am still working on sizing this project. I will update this topic if we use X240 and DAC cables.

Hi,

Did you end up going forward with this design? I'm currently experiancing issues with connecting a new VNX5200 (Block only) to a HP 5920-24XG with X240 DAC cables.

If you were successful it would be great to hear how you achieved this.

I currently have a support case open with EMC and will see how that goes.

Regards.

Actually this project cancelled and we haven't have chance to use it.

Also you may find mentioned list of cables which "tested" but "not certified".
