Formatting Virtual Disks

Before you format virtual disks with VMFS datastores, you must plan how to set up storage for the ESX/ESXi systems,

including deciding on the number and size of virtual disks to use.

NOTE: For more information about making virtual disk decisions, including predictive schemes, adaptive schemes
and disk shares, refer to the

iSCSI SAN Configuration Guide: Using ESX/ESXi with an iSCSI Storage Area Network:

Making LUN Decisions

in the VMware vSphere Online Library.

When you are deciding how to format virtual disks, keep the following considerations in mind:

Ensure that each virtual disk has the correct RAID level and storage characteristics for applications in the

virtual machines using that virtual disk.

Ensure that each virtual disk contains only one VMFS datastore.

When multiple virtual machines access the same VMFS datastore, use disk shares to prioritize virtual machines.

Fewer, larger virtual disks are appropriate for the following reasons:

Provide more flexibility to create virtual machines without increasing space.

Provide more flexibility for resizing virtual disks and performing snapshots.

Result in fewer VMFS datastores to manage.

More, smaller virtual disks are appropriate for the following reasons:
