Use dynamic volumes on dynamic disks to take advantage of advanced disk configurations that provide for increased performance or fault tolerance. The following table describes the dynamic volume types:
Volume Type | Description |
Simple | A simple volume contains a single, contiguous block of space from a single hard disk.
|
Spanned | A spanned volume combines areas from two or more disks into one storage unit. The primary purpose of a spanned volume is to add more storage space to an existing volume. A spanned volume:
|
Striped (RAID 0) | A striped volume breaks data into units and stores the units across a series of disks. When you save a single file on a striped volume, pieces of the file will be found in all disks in the array. Striped volumes:
|
Striped with parity (RAID 5) | A striped volume with parity combines disk striping across multiple disks with parity for data redundancy. Parity information is stored on each disk. If a disk fails, its data can be recovered using the parity information stored on the remaining disks. RAID 5 volumes:
|
Mirrored (RAID 1) |
A mirrored volume stores two copies of each file, with one copy on each disk or disk set. Mirrored volumes:
Disk duplexing is a type of mirroring. Disk duplexing uses two hard drives and two separate disk controllers. Disk duplexing eliminates the single point of failure when a single disk controller is used. |
