Hello,
You can use the DAC cable with thrid party switches as long as the switch supports 10Gb.
If you use the 10Gb SFPs, they do not support LR (Long Range) which is traditionally used in multi-mode or single-mode cabling schemes. The MSA does not support a distance over ~300m so the LR SFPs are not tested with an MSA array.
As mentioned, earlier confirm your options using the HPE Quickspecs page for the MSA 2040: https://h20195.www2.hpe.com/v2/getdocument.aspx?docname=c04123144
Cheers,
Shawn
