I have vcenter 6.5 and two esxi hosts ( v6.5 ) . I want to learn srm install and configuraiton. is it possible that I can install with my vmware infrastructure ?
SRM requires two vCenter server, so you will need at least another vCenter (and that vCenter should manage at least one ESXi host).
Another option is just to use the VMware Hands-on Labs, see: http://labs.hol.vmware.com/HOL/catalogs/lab/2711
