Hello All,
I would like to ask anyone has information or experience about using DAC Cable for 10G networking on Isilon nodes? Or the !only option is 10G SFP+ Optics?

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.

Isilon Practice has a list of working Twinax cables maintained by Andrew Chung

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".

Thanks for getting back to me, sadly I don't have permission to view that link.
Was there any mention of the HP X240 in that list?

Just heard back from EMC support and they confirmed that the X240 cables are not support as they are Passive not Active. Very annoying as these are the only cables recommended for the HP 5900 Series.
Hope this helps for other people looking at the new ToR HP switches
