While VMware is still working on an app to manage VMware hosts from the iPad (to be released early 2011), there is already an iPad app available for administering the virtual datacenter from everywhere using the iPad. It is called iDatacenter and is developed by a Swedish company called Nym Networks. The current version is 1.1.1. The first version of the product was released mid 2010.
The application is available at the Apple App Store and costs Euro 11,99
The following features are supported in the current version of iDatacenter:
•Aggregate statistics per datacenter.
•Individual statistics and status for each physical host, virtual machine.
•Search/filter to find the host or virtual machine you are looking for.
•Use Storage vMotion to migrate a virtual machine from one datastore to another.
•Suspend and power on/off virtual machines.
•Soft reboot and soft shutdown of virtual machine with VMWare Tools installed.
•Enter and exit maintenance mode, disconnect and reconnect, reboot or shutdown hosts.
•Data cache for fast startup and navigation.
More information including a video can be found on the website of Nym Networks, the creator of iDatacenter.
