"Can I get confirmation that ISO should have all needed drivers for the VRTX system using M520 blades?"  EricNylen, You can, the customized ISO does contain the drivers needed, but the version you download is the one needed for the M1000e's M520, not the one for the VRTX (as "PowerEdge M520 (for PE VRTX)" line in compatible systems would be listed). The version you need can be found here though. Also, you can find a detailed walk through on configuring the Shared Storage in the VRTX here.  Let me know how it goes.
I have installed ESXI 6 with the following ISO VMware-VMvisor-Installer-6.0.0-2494585.x86_64-Dell_Customized-A00 www.dell.com/.../DriversDetails When I go to "Add Storage" in the vSphere client it does not show any disk drives available. - I have created Virtual Disks on the VRTX - I have associated the 2 blades with a VA each on all disks - The VD's are in multiple connection mode - I have rebooted the hosts Can I get confirmation that ISO should have all needed drivers for the VRTX system using M520 blades? Have I missed anything? Thank you in advance Eric
