Disk management server

  1. 1. Server 2008 Disk Management
  2. 2. Disk Partition  Disk partitioning is the act of dividing a hard disk drive into multiple logical storage units referred to as partitions, to treat one physical disk drive as if it were multiple disks. Partitions are also termed "slices" for operating systems based on BSD, Solaris or GNU Hurd.
  3. 3. Disk formatting  Disk formatting is the process of preparing a data storage device such as a hard disk drive, solid-state drive, floppy disk or USB flash drive for initial use.
  4. 4. Basic Disk Storage  A basic disk uses primary partitions, extended partitions, and logical drives to organize data. A formatted partition is also called a volume (the terms volume and partition are often used interchangeably). In this version of Windows, basic disks can have either four primary partitions or three primary and one extended partition. The extended partition can contain an unlimited number of logical drives. The partitions on a basic disk cannot share or split data with other partitions. Each partition on a basic disk is a separate entity on the disk.
  5. 5. Dynamic Disk Storage  Dynamic disks can contain an unlimited number of dynamic volumes that function like the primary partitions used on basic disks.  The main difference between basic disks and dynamic disks is that dynamic disks are able to split or share data among two or more dynamic hard disks on a computer.  For example, a single dynamic volume may actually be made up of storage space on two separate hard disks. Also, dynamic disks can duplicate data among two or more hard disks to guard against the chance of a single disk failing.  This capability requires more hard disks, but improves reliability.
  6. 6. Dynamic Storage Terms  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 on dynamic disks can have any of the following layouts: simple, spanned, mirrored, striped, or RAID-5.
  7. 7. A simple volume  A simple volume uses free space from a single disk. It can be a single region on a disk or consist of multiple, concatenated regions. A simple volume can be extended within the same disk or onto additional disks. If a simple volume is extended across multiple disks, it becomes a spanned volume.
  8. 8. A spanned volume  A spanned volume is created from free disk space that is linked together from multiple disks. You can extend a spanned volume onto a maximum of 32 disks. A spanned volume cannot be mirrored and is not fault-tolerant.
  9. 9. A striped volume  A striped volume is a volume whose data is interleaved across two or more physical disks. The data on this type of volume is allocated alternately and evenly to each of the physical disks. A striped volume cannot be mirrored or extended and is not fault-tolerant. Striping is also known as RAID-0.
  10. 10. A mirrored volume  A mirrored volume is a fault-tolerant volume whose data is duplicated on two physical disks. All of the data on one volume is copied to another disk to provide data redundancy. If one of the disks fails, the data can still be accessed from the remaining disk. A mirrored volume cannot be extended. Mirroring is also known as RAID-1.
  11. 11. A RAID-5 volume  A RAID-5 volume is a fault-tolerant volume whose data is striped across an array of three or more disks. Parity (a calculated value that can be used to reconstruct data after a failure) is also striped across the disk array. If a physical disk fails, the portion of the RAID-5 volume that was on that failed disk can be re-created from the remaining data and the parity. A RAID-5 volume cannot be mirrored or extended.
  12. 12. The system volume  The system volume contains the hardware- specific files that are needed to load Windows (for example, Ntldr, Boot.ini, and Ntdetect.com). The system volume can be, but does not have to be, the same as the boot volume.
  13. 13. The boot volume  The boot volume contains the Windows operating system files that are located in the %Systemroot% and %Systemroot%'System32 folders. The boot volume can be, but does not have to be, the same as the system volume.
  14. 14. Lab  Prerequisites:  Before working on this lab, you must have  A computer running windows 2008 server with at least 3 Hard disks.
