4.2 © 2004 Pearson Education, Inc. Exam Managing and Maintaining a Microsoft® Windows® Server 2003 Environment Lesson 4: Organizing a Disk for Data Storage Dynamic disks support the following types of volumes Simple volume – consists of disk space from a single hard disk, an entire disk, or multiple regions on the same disk that are linked together Spanned volume – consists of disk space from multiple disks. Striped volume (RAID-0) – combines areas of free disk space from two or more hard disks Mirrored volume (RAID-1) – is created using the free disk space on two physical hard disks RAID-5 volume – is a fault-tolerant, striped, dynamic volume that combines free disk space from 3 to 32 physical hard disks Introducing Storage Types (2) (Skill 1)
