Is your storage still based on LUNs and volumes? Does your storage understand virtual machine and can provide VM-level data management, protection, automation and analytics?
If not, you are probably still living in the same world as Carl, whose life is taken over by dumb storage. Carl can't see across his hosts, network, and storage what causes performance problems. Carl's storage can't dynamically learn and adapt to the needs of virtualized apps, nor can they handle virtual servers and virtual desktops simultaneously.
Need to deploy thousands of VMs or tear them down quickly? Forget it. That's extra pain. Take a look at what Carl is experiencing.
