Last week I’ve installed some Dell hosts with VMware vSphere 5.1 and used Dell Eq. PS6000 storage. To configure the connection between host and storage optimal I’ve used the Dell Equallogic Multipathing Extension witch is supported for vSphere 5.x
The SATP VMW_SATP_EQL is a VMware default one for EqualLogic arrays. And of course the PSP is DELL_PSP_EQL_ROUTED. The ‘ROUTED’ part refers ot DELL’s MEM being able to intelligently route I/O requests to the array path best suited to handle the request, to configure this with PowerCLI I’ve used the following code:
Get-VMHost HOST | Install-VMHostPatch -HostPath "/vmfs/volumes/VMFS-009-SSD/dell-eql-mem-esx5-22.214.171.1240268/metadata.zip"
The DELL_PSP_EQL_ROUTED is configured automatically and the path selection is selected
