816307 Best practices for using dynamic disks on Windows Server 2003-based computers

Dynamic volume

A volume on one or more dynamic disks.

Dynamic volumes provide greater functionality as compared to basic volumes; but older operating
systems, such as Windows 98, might not be able to work with them.

Different types of dynamic volumes suit different purposes. For example, you can:

Increase the volume size beyond the capacity of a single disk, by using a spanned volume

Reduce access time to files, by using a striped volume

Achieve fault tolerance, by using a mirrored volume

For a complete list of volume types, see Volume type (p. 94).

F

Fault tolerance

The ability of a volume to ensure data integrity after a hardware failure.

Fault tolerance is usually achieved by introducing data redundancy, which enables preserving data in
case one of the hard disks containing the volume fails.

Examples of fault-tolerant volumes include mirrored (p. 90) and RAID-5 (p. 91) volumes.

File

A set of data, such as a text document, that is stored under an identifying name—for example:
Document.txt
