Using more multipath software in one system

[Jan Soska]

Hello all,
it seems we are going to use more different arrays on one system soon.
Does anybode have experience with installing HP MPIO for EVA and EMC multipath and one system at the same time? Or even third multipath software (for Falconstor)?

Any experience welcomed.

Which operating system do you have?

Hello,
in this case lets thing about win2008 64bit and win2008R2. The same problem we will have under linux RH 4-5-6, but thats another story.
Keep it on windows now.

Hi

Multipathing software is designed in the way that you should be able to have several instances of it installed on the same system. They should have no influence one on the each other.

I asked both vendors (HP, EMC) for official statement. As expected, both say it is not supported :) .
We will test it and see...

So, after couple months of testing we can say it works. For example under windows we use HP MPIO together with Falconstor Dynapath, no problem.

Under linux (RH6) is situation even better, native multipath from RH is quite ok (after lots of tuning) and supports all arrays in one system - HP EVA, EMC CX4, Falconstor NSS
