With 3i, instead of executing scripts directly on the Linux-like console, administrators will have access to a remote command line interface (CLI) from a standalone virtual infrastructure (VI) client to perform old ESX commands, said Raghu Raghuram, VMware vice president of platform products.
But remote CLI allows administrators to invoke only ESX-specific commands, such as those that start with the "esxcfg" string; Linux-specific facilities are not included. That means that "the commands we use to gather information will remain the same but how we invoke them will have to change," said Alistair Sutherland, director of Taupo Consulting, a VMware integrator in Edinburgh, Scotland.
Granted, running scripts in the service console is somewhat of a relic from a previous era, said VMware's Raghuram, even if the practice persists today. "Before VirtualCenter, we had the service console concept, and we used to encourage people to go there," he said. But with the advent of VirtualCenter in 2004, VMware introduced a set of application programming interfaces (APIs) that people can use to interact with ESX hosts, and "that philosophy is still unchanged; both 3 and 3i still connect to VirtualCenter."
