View your VMware ESXi Host’s System Log, Config and Datastore via a Web Browser

Looking for an easy way to view your VMware ESXi host’s System LogsConfig Files andDatastore?  This rather nifty ESXi feature will save you the hassle of having to log onto the ESXi console to view any of these items.  All you simply have to do is open a web browser and enter in one of the two URLs (see below) – depending on what you’re wanting to access.  Keep in mind that what is displayed in the web browser is read-only.

ESXi Configuration Files & System Logs:

How many VMs per DataStore should I have?

Although there are no steadfast rules for how many virtual machines should be placed on a datastore due to the scalability enhancements of VMFS-5, a good conservative approach is to place anywhere between 15-25 virtual machines on each.

The reasoning behind keeping a limited number of Virtual Machines and/or VMDK files per datastore is due to potential I/O contention, queue depth contention, or Legacy SCSI reservation conflicts that may degrade system performance.

This is why I suggest limiting your datastore size to 500GB-700GB each, because this helps limit the total number of virtual machines that can be placed on each datastore.
