 +If you delete a required partition, be sure to create a new one of the same type. You cannot define the sizes of the /boot, vmkcore, and /vmfs partitions when you use the graphical or text installation modes. You can define these partition sizes when you do a scripted installation.

 += ESX Required Partitions =
 +
 +^ Mount Point ^ Type ^ Size ^ Location ^ Remarks |
 +| /boot | ext3 | Bootdisk = 1.25 GB \\ /boot partition 1100 MB \\ vmkcore partition 110 MB |Physical partition |This is where grub is located. |
 +| | vmkcore | Bootdisk = 1.25 GB \\ /boot partition 1100 MB \\ vmkcore partition 110 MB |Physical partition not on a software iSCSI volume |Used to store core dumps for tech support |
 +| | VMFS3 | esxconsole.vmdk:​ 1200 MB |Physical partition that is only accessible to the host |Used to store virtual machines |
 +| | swap | Minimum: 600 MB \\ Maximum: 1600 MB |Virtual disk in VMFS volume |ESX SWAP space |
 +| / | ext3 | Default: 5 GB | Virtual disk in VMFS volume |ESX OS and services (and addons/​applications) |
 +
 +> Note: As a general rule, swap files are created with a size equal to at least two times the memory allocated to the operating system. The installation process allocates a default amount of 300MB of memory for the Service Console; therefore, the default swap partition size would be 600MB.

 +| /home | ext3 | 512 MB | Virtual disk in VMFS volume | |
 +| /tmp | ext3 | 1024 MB | Virtual disk in VMFS volume | |
 +| /usr | ext3 | No recommendation | Virtual disk in VMFS volume | |
 +| /var/log | ext3 | 2000 MB | Virtual disk in VMFS volume |Used for logfiles, this partition is created by default. |
