how much lun can assign to vmware
Re: How to handle LUN limit on vsphere with NetApp. â2013-03-25 08:08 AM. The 256 LUN limit is one imposed by VMware and I'm not sure if they plan on increasing it soon. You should relay this back to your VMware account teams.ou can only even have 255 LUN mounted to any given ESX server. Thats an ESX limit. However you really should have all LUNs connected to all ESX servers in a cluster (VMware best practice) otherwise it can become very confusing to try to move VMs around using VMotion as you will have hosts certain VMs can't get to.
