Default Service Console Partition Values for ESX4.0 and Explanations

If a default installation of ESX4.0 or Vsphere were to be done the values would be the same as what you will see in this post. Except for the VMFS volume which will depend on the storage available for you at the time of installation. There are required partitions and optional partitions, You may slightly increase the values depending on available storage and design considerations. A good resource for the maximum guide is available from VMware or the VMware Cookbook from O'reilly Publishing which covers this quite in depth.

Example:

Storage Device: mpx.vmhba0:C0:T0:L0

Service Console Partitions (Required):

The below partitions are for ESX, which are created during installation, with the exception of /var/log which is optional but gets created by default when the graphical or text installer is used.

vmkcore 110MB debug information for tech support  Cannot be on a software iSCSI Volume


vmfs3 39.75GB where VM's will reside this varies


swap 600MB ESX swap; minimum is 600MB maximum is 1600MB


ext3 5.00GB ESX OS and services accessible through the service console.  Also contains 3rd Party services or applications installed


ext3 1.10 GB /boot Information required to boot the ESX OS, e.g. where the Grub loader resides


ext3 2.00 GB /var/log Used for logs

Optional Partitions

/home (512MB and above recommended - storage for individual users)
/usr (1024MB and above recommended - used for user programs and data)
/var/log (2000MB and above recommended - used for logs, I would recommend 4000MB)
