Hi there:

Wanted to know what will be a good approach to use VNX 5400 Block only device as NAS also. Here is my  take

Create two LUNS on VNX one to store/run VM's and the second one to use it as NAS.

To use the second LUN as NAS  - I will have a VM running linux and configure iSCSI to access this LUN. Then mount this device and format it with a FS and then export that path.

Cheers and thanks for looking into it.
