CHAPTER 6 Administering ESX Server

If it does not exist, you are asked if you want to create a core dump partition.
The core dump partition stores information generated if the VMkernel crashes.
The core dump information is important in debugging any problems with the
VMkernel.
The rest of the disk or array is used as a VMFS partition, where you store virtual
machine disk files. The VMFS partition provides high-performance access to the
virtual machine’s files — essentially the same performance you would get if the
virtual machine were installed on a raw SCSI partition.
Note: Keep in mind that only four primary partitions can exist on a drive. If you
have an extended partition (to contain logical partitions), that counts as one of
your four primary partitions.
3. Click Yes to create the core dump partition. ESX Server also creates the VMFS
partition.
After you create the partition, you can add a volume label, determine access mode
and the maximum file size and span the disk with any public extents. For more
information about access modes, see VMFS Accessibility on page 257.
