Lesson 4: Organizing a Disk for Data Storage

Storage types used by Windows Server 2003 Basic storage (divides a hard disk into partitions)Dynamic storage (divides a hard disk into volumes)

Basic disk supports the following types of partitionsPrimary partition – a physical unit of storage created on a

basic diskExtended partitions – created from free space that has not

yet been partitioned

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

Upgrading a Disk from Basic to Dynamic

By default, the hard disk on a Windows Server 2003 computer is initialized with basic storage

When you upgrade a basic disk, the existing partitions are converted into simple volumes

Use the Disk Management snap-in to upgrade a basic disk to a dynamic disk

Introducing Spanned, Striped and Mirrored Volumes

Spanned volumes Creating a spanned volume

Combines the unallocated space on multiple disks into one logical volume

A spanned volume can organize disk space on up to a maximum of 32 disks

Spanned disks allow you to combine the space used by multiple, smaller volumes, on multiple disks, into one spanned volume represented by a single drive letter

Lesson 4: Organizing a Disk for Data Storage

Striped volumes As with spanned volumes, you can combine disk

space from a maximum of 32 disks to create a striped volume

On a striped volume, data is divided in blocks of 64 KB across each segment of the volume

Data is simultaneously written across all of the disks so that it is added to the disks at the same rate

Mirrored volumes A mirrored volume provides fault tolerance because

you create two drives that are duplicates of each other

Mirrored volumes are inefficient in some respects because fifty percent of the available disk space is consumed by fault tolerance

Defragmenting Volumes and Partitions The Disk Defragmenter rearranges files and unused

space, moving the segments of each file and folder to one location so that they occupy a single, contiguous space on the hard disk

Enhancements In Windows XP and Windows Server 2003, file system

defragmenter support is no longer dependent on compressed file routines and the Cache Manager

Limitations on defragmenting volumes with cluster sizes larger than 4 KB and on moving single NTFS file clusters have been remedied
