Dynamic Disk Types and Details
A dynamic disk is a disk type, widely used in the server field. Created by the different from a basic disk to a dynamic disk volume is not a primary partition, but the dynamic volume. There is a big difference of dynamic disks and basic disks. Effectively manage the server for each user using a dynamic disk to a dynamic disk and method of the Profile Wizard to create various types of dynamic volumes dynamic disk.
5 types of synamic disks:
Basic includes only primary partitions and logical partitions, although there are 5 types of dynamic volumes include simple, spanned volumes, striped volumes, mirrored volumes, and RAID-5 volumes. Characteristics of different volumes have different dynamically.
Simple volume:
Simple is the most simple dynamic volumes, and there is no big difference between basic partitioning, dynamic simple volumes. However, we can create any number of simple volumes, as long as disk space allows. In addition, dynamic disk can break the limit of disk space, that is using disk space to extend the simple volume you want.
Spanned volume:
Between the dynamic volumes spanned volumes can be used on most 32 disk space to create the volume, enabling full utilization of resources on the disk. This is sad, this can improve the performance and fault tolerance.
Striped volume:
Striped volumes can instructions to speed up access to data of dynamic volumes. , When we write data, the data is partitioned into 64 KB data block, then to the striped volume disk writes data at the same time. However, this dynamic volume did not feature tolerance mistakes, either.
Mirrored volume:
Users who are familiar with RAID disk know that RAID 1 has a very high level of security, because you can make mirror backups, stored data. As a RAID 1 mirrored volume is a dynamic volume. When we store data, mirrored volumes will generate a complete transcription of it and save it on another drive. Therefore, mirrored volumes require 2 discs.
RAID-5 volume:
Rectify the deficiency does not provide fault tolerance, RAID 5 digits added. RAID 5 is also called volume cross-functional tolerance and contain at least 3 disks and a maximum of 32 disks. When a disk fails during operation, when the other disk information can be manipulated and disk data recovery failed at the same time. Thus, RAID 5 has a relatively high proportion of all dynamic volumes.
