Can i go for Essentials kit (For SMB's) for enabling clustering?
I don't see why you should not be able to create a cluster with the Essentials Kit. However, only "Essentials Plus" (or better) offers advanced functions like HA or vMotion. See http://www.vmware.com/files/pdf/vsphere_pricing.pdf

I didn't configured till now, but i want to know whether it supports clustering or not. Based on that only i have to suggest to client.
