vSphere Client and vSphere Web Client Software Requirements
Make sure that your operating system supports the vSphere Client.
For the most current, complete list of supported operating systems for the vSphere Client and the
vSphere Web Client, see the VMware Compatibility Guide at
http://www.vmware.com/resources/compatibility.
The vSphere Client requires the Microsoft .NET 3.5 SP1 Framework. If it is not installed on your system, the
vSphere Client installer installs it. The .NET 3.5 SP1 installation might require Internet connectivity to
download more files.
The following browsers are supported for the vSphere Web Client:
n
Microsoft Internet Explorer 7 and 8
n
Mozilla Firefox 3.6
The vSphere Web Client requires the Adobe Flash Player version 10.1.0 or later to be installed with the
appropriate plug-in for your browser.
Providing Sufficient Space for System Logging
ESXi 5.0 uses a new log infrastructure. If your host is deployed with Auto Deploy, or if you set up a log directory
separate from the default location in a scratch directory on the VMFS volume, you might need to change your
current log size and rotation settings to ensure that enough space for system logging exists.
All vSphere components use this infrastructure. The default values for log capacity in this infrastructure vary,
depending on the amount of storage available and on how you have configured system logging. Hosts that
are deployed with Auto Deploy store logs on a RAM disk, which means that the amount of space available for
logs is small.
If your host is deployed with Auto Deploy, reconfigure your log storage in one of the following ways:
n
Redirect logs over the network to a remote collector.
n
Redirect logs to a NAS or NFS store.
You might also want to reconfigure log sizing and rotations for hosts that are installed to disk, if you redirect
logs to nondefault storage, such as a NAS or NFS store.
You do not need to reconfigure log storage for ESXi hosts that use the default configuration, which stores logs
in a scratch directory on the VMFS volume. For these hosts, ESXi 5.0 autoconfigures logs to best suit your
installation, and provides enough space to accommodate log messages.
