Standard Image file disk is an RAW disk image file in KernSafe iSCSI SAN. KernSafe iSCSI SAN Server will create a disk based on an image file in host physical hard drive. The image file will be exported to an iSCSI device by the iSCSI server. The file operations to the iSCSI device will be converted to operating the image file automatically. Image file disk is the most popular way to create the iSCSI device, the image file allows quick data migration, backup and restore, so it is suitable for most of situations.
