Re: Ask the Expert: VMware and VNX Integration Best Practices
If you have the possibility to buy licenses of Powerpath its the best option recommended by EMC to manage multipathing on a VMware environment.
PowerPath can effectively manage all of the I/O multi-pathing complexity. It constantly adjusts the I/O path usage to changes in loads generated by the VMs. Management is vastly simplified. Just assign all devices (LUNs) to all available paths and PowerPath will optimize the overall I/O performance for the ESXi environment.
If needed, you can choose to provide additional QoS management for the most important applications by managing LUN and path prioritization.
If you don't have the possibility to use powerpath for license problems or another problems on your infrastructure Fixed its the best option for ESXI for VNX if you configure the trespassing with the correct paths by the side of ESXI you shouldn't have problems.
Do not hesitate to contact me if you have any questions or concerns.
Thanks and Regards.
