Servers produced in no time, hassle free. Can clone the virtual machine if maintenance require on production servers. Can be integrated with almost all storage solutions like HP storage, Nutanics, Netapp, Dell EMC, IBM storwize , SVSAN, IBM DS3500 etc. Very clear and easy to work GUI, as the inventory shows up clear demarcation with Datacenters, Virtual machine clusters, Hypervisor Hosts and virtual machines.
Templates are the best in VSphere as we are able to create servers and push them into production in no time.
Virtual machine snapshots work pretty well as temporary backup solutions, even it is not their intended purpose of usage.
It is good that vmware lifted the restrictions on the size of Logical unit numbers as it was much difficult earlier to deploy larger virtual machines with high storage amount of VMDK storage file.
VMWare vsphere is good at alerting about the system Hosts, storage units when failed or enter an erroneous state.
Virtual center availability and Virtual machine availability is one of the awesome features vsphere incorporated as the virtual machines re distribute among different hosts to load balance the traffic hitting the hosts and VM's move to different hosts when the a bad host is sensed.
Hard to configure virtual switches and VLAN's. Support could be better.
Most of the times support sends KB articles, instead of taking a webex session or similar
