We have a number of WIndows 2008/2012 Failover Cluster running in VMware but I need to build a two node Widows Cluster that will a have 50 RDM's present to it. It is for a special archive application which uses mount point in the OS. I have never presented this many RDM's to a VM be for. Also each LUN has 8 paths which means there will be 480 paths just for this VM not including the 4 attached datastore bring the number of paths up to 512. I know the max number of path per host is 1024 for FC/ Fcoe

Are there any performace problems I should be aware of. Also I hate to say it and one host is running ESXi  6 and the other host are running 5.1 which I know is not supported any more.

Should not be any issues, all within maximums for ESXi 6.0 and ESXi 5.1 (retired, no longer on support!)

1024 max paths per ESXi host, 60 targets per virtual machine, 32 paths per LUN

so all looks good there for 6.0 and 5.1.

IS there any easy way to list all RDM in at the cluster level and confirm the reservation setting was updated correctly

Problem with scripts, is they need to be continuously updated, as functions in PowerCLI are deprecated!

well a script is the answer.

if you don't have a script, you could always check a random sample of the 50.

Although we always like belt and braces approach, and take time to check manually.
