Section 12 MANAGING DISK STORAGE

Slide 2

Chapter 12: MANAGING DISK STORAGE CHAPTER OVERVIEW Understand plate stockpiling ideas and phrasing Distinguish amongst essential and element stockpiling Identify the sorts of capacity volumes bolstered on Windows Server 2003 oversaw circles Identify the best RAID execution given a specific stockpiling prerequisite as far as limit usage, adaptation to internal failure, and execution Add stockpiling to a Windows Server 2003 PC Manage circles utilizing Check Disk, Disk Defragmenter, and plate portions

Slide 3

Chapter 12: MANAGING DISK STORAGE UNDERSTANDING WINDOWS SERVER 2003 DISK STORAGE Disk The physical gadget Partition A range of the circle that capacities as a physically isolate unit of capacity Volume A zone of a parcel utilized for putting away information

Slide 4

Chapter 12: MANAGING DISK STORAGE USING BASIC STORAGE Supported by all forms of Windows and MS-DOS The default stockpiling sort for Windows Server 2003 Each circle is separated into segments, which can be either essential or amplified

Slide 5

Chapter 12: MANAGING DISK STORAGE USING DYNAMIC STORAGE Supported by Windows 2000, Windows XP, and Windows Server 2003 One plate, one segment Volumes are made inside the segment Supports crossing, striping, and RAID executions

Slide 6

Chapter 12: MANAGING DISK STORAGE BASIC VS. DYNAMIC DISKS By default, all plates are fundamental. Essential plates can be effortlessly changed over to element circles. Changing over a circle from element to fundamental causes all information to be lost.

Slide 7

Chapter 12: MANAGING DISK STORAGE USING DISK MANAGEMENT

Slide 8

Chapter 12: MANAGING DISK STORAGE ADDING STORAGE Physically introduce the disk(s). Introduce the circle. On a fundamental plate, make parcels. On a dynamic plate, make volumes. Organize the volumes. Relegate drive letters to the volumes.

Slide 9

Chapter 12: MANAGING DISK STORAGE INSTALLING A DISK Physically introduce the plate. Windows Server 2003 ought to perceive the new gadget consequently. In the event that it doesn\'t, select Rescan Disks from the Action menu in Disk Management.

Slide 10

Chapter 12: MANAGING DISK STORAGE INITIALIZING THE DISK All plates must be instated before they can be utilized. Instatement causes the MBR (essential circle) or GPT (dynamic plate) to be composed. The Initialize And Convert Disk Wizard ought to dispatch naturally after another plate is introduced.

Slide 11

Chapter 12: MANAGING DISK STORAGE CREATING BASIC DISK PARTITIONS

Slide 12

Chapter 12: MANAGING DISK STORAGE CONVERTING A BASIC DISK TO A DYNAMIC DISK Make a reinforcement before changing over. Segments and consistent drives are changed over to straightforward volumes. Existing Windows NT volume sets and stripe sets are changed over to traversed volumes and striped volumes, individually.

Slide 13

Chapter 12: MANAGING DISK STORAGE CREATING DYNAMIC DISK VOLUMES

Slide 14

Chapter 12: MANAGING DISK STORAGE CREATING SIMPLE VOLUMES A basic volume can be made from free space on a solitary plate. A basic volume can be augmented utilizing free space on a similar circle, the length of it is not the framework/boot volume. To make a basic volume utilizing the New Volume Wizard, in the Disk Management reassure, right-click unallocated space on a plate and select New Volume.

Slide 15

Chapter 12: MANAGING DISK STORAGE CREATING OTHER VOLUME TYPES Spanned Uses space from numerous plates showing up as single volume Striped (RAID-0) Uses space from different circles showing up as single volume; information is composed over all drives in the striped set at a similar rate. Reflected (RAID-1) An indistinguishable duplicate of a volume is made on another physical circle, for adaptation to internal failure. Assault 5 Striped set with equality permits the framework to keep running in case of a solitary circle disappointment.

Slide 16

Chapter 12: MANAGING DISK STORAGE WORKING WITH MIRRORED VOLUMES Data is composed to both drives at the same time. Can be utilized to give adaptation to non-critical failure to the framework/boot volume on a Windows Server 2003 framework. Does not corrupt execution.

Slide 17

Chapter 12: MANAGING DISK STORAGE CONVERTING A SIMPLE VOLUME TO A MIRRORED VOLUME Only necessity is a drive with adequate space to hold the reflected information. Information is replicated to the new drive part by area. Drive\'s status in the Disk Management support appears as resynching while information is replicated.

Slide 18

Chapter 12: MANAGING DISK STORAGE RECOVERING FROM MIRRORED DISK FAILURES

Slide 19

Chapter 12: MANAGING DISK STORAGE WORKING WITH RAID Non-blame tolerant RAID executions RAID-0: Disk striping without equality Fault-tolerant RAID usage RAID-1: Disk reflecting RAID-5: Disk striping with equality

Chapter 12: MANAGING DISK STORAGE FORMATTING VOLUMES

Slide 23

Chapter 12: MANAGING DISK STORAGE EXTENDING DYNAMIC VOLUMES

Slide 24

Chapter 12: MANAGING DISK STORAGE MANAGING DISK STORAGE Using Check Disk Using Disk Defragmenter Implementing circle portions

Slide 25

Chapter 12: MANAGING DISK STORAGE USING CHECK DISK

Slide 26

Chapter 12: MANAGING DISK STORAGE USING DISK DEFRAGMENTER

Slide 27

Chapter 12: MANAGING DISK STORAGE IMPLEMENTING DISK QUOTAS

Slide 28

Chapter 12: MANAGING DISK STORAGE ENABLING Quotas are empowered on a volume-by-volume premise Exceptions to amounts can be designed on a for every client premise Every record possessed by a client numbers toward her standard aggregate

Slide 29

Chapter 12: MANAGING DISK STORAGE CONFIGURING QUOTA DEFAULTS Set cautioning levels to ready clients when they approach their share restrict. Set limitations to keep clients from surpassing their share constrain. Logging identified with standard occasions can be empowered.

Slide 30

Chapter 12: MANAGING DISK STORAGE CREATING QUOTA ENTRIES

Slide 31

Chapter 12: MANAGING DISK STORAGE EXPORTING QUOTA ENTRIES Allows amount settings to be connected to another volume. Goal volume must be organized with NTFS. Just cutoff points and arrangements are traded, not the present amount use.

Slide 32

Chapter 12: MANAGING DISK STORAGE MONITORING QUOTAS AND STORAGE Quota points of confinement and rate utilized can be seen through the Quota Entries exchange box. The Quota Entries discourse box can be gotten to by survey a volume\'s properties in Windows Explorer or Disk Management.

Slide 33

Chapter 12: MANAGING DISK STORAGE SUMMARY Windows Server 2003 backings two sorts of capacity, fundamental and element, and three record frameworks, FAT, FAT32, and NTFS. Fundamental circles and the FAT record framework furnish back-ward similarity with more seasoned Windows working frameworks yet are constrained in their abilities. Dynamic circles give adaptable and effective choices in setups with more than one plate.

Slide 34

Chapter 12: MANAGING DISK STORAGE SUMMARY (proceeded with) Basic circles can be changed over to element plates without any information misfortune, yet all information and volumes must be erased to change over a dynamic plate to a fundamental circle. Dynamic circles bolster straightforward, spread over, striped, reflected, and RAID-5 volumes, to give stockpiling as per limit, execution, and adaptation to internal failure necessities.

Slide 35

Chapter 12: MANAGING DISK STORAGE SUMMARY (proceeded with) Fault resistance is given by reflected (RAID-1) volumes and striped-with-equality volumes (RAID-5). Basic volumes, spread over volumes, striped volumes (RAID-0), and all essential plate coherent drives are not blame tolerant. You utilize the Disk Management snap-into make and oversee fundamental and element plates.

Slide 36

Chapter 12: MANAGING DISK STORAGE SUMMARY (proceeded with) Disk volumes can get to be distinctly ruined or divided and frequently completely fill. You can oversee existing volumes utilizing apparatuses, for example, Check Disk, Disk Defragmenter, and Quota Manager. You can utilize circle shares to set and screen stockpiling limits and deny compose access to clients who surpass those cutoff points.
