No The MD3000 will not be compatible with the Perc5E. Below is a link that will take you to the compatibility matrix. The Perc5E is a raid card and that will not work with the array.  support.dell.com/.../Sup_Matx.pdf Please let me know if you have any questions and I  would be happy to assist.
I am asking to see if a PowerVault MD3000 will work with a PowerEdge 2950 with Perc 5E installed?  I'm asking because all of my SAS 5/E cards has blown up (they will not be detected anymore and they won't even show up in the POST status at boot time). If MD3000 will work with Perc 5E, then is there a special configuration I need to do to get it be recongized? Assistance please. Thanks
Will MD3000 work with Perc 5E ?
