I've been using the free ESXi for years and now I'm interested in learning other VMware technologies. What else should I try? I have access to VMware licenses but since it's not production I wouldn't mind if they were actually legal or not anyway.
Try clustering stuff like vMotion, FT, HA,vNetwork Distributed Switch. Setup vCenter Server to manage all this. Build a NAS box for some shared storage.
Just one ESXi 5/ZFS box right now but I could build a second one. Not sure how I'm going to load balance the ZFS storage if thats even possible since OpenSolaris is virtualized.
