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.
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.
