•Chapter 6: Configuring File Services•Exercise•Lab•Midterm Exam
![Page 3: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/3.jpg)
File Server
•Implementing basic file server functions requires▫The File Server role▫Basic server administration tasks:
Installing disks Creating shares Assigning permissions Mapping drive letters
![Page 4: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/4.jpg)
Working with Disks
•When you install additional storage on a Windows Server 2008 computer, you must address the following tasks:▫Select a partitioning style; MBR? GPT?▫Select a disk type; Basic? Dynamic?▫Divide the disk into partitions or volumes
Create partitions on basic disks, and volumes on dynamic disks
▫Format the partitions or volumes with a file system; NTFS? FAT?
![Page 5: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/5.jpg)
Partition Style
•Master Boot Record (MBR)▫The default partition style for x86-based
and x64-based computers•GUID (Globally unique identifier) partition
table (GPT)▫Only Windows Server 2k8, Windows Vista,
or later. ▫Windows XP Professional x64 Edition does
support GPT
![Page 6: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/6.jpg)
Basic Disks and Partitions
•When you work with basic disks in Windows Server 2008:▫You can create up to four primary
partitions▫OR 3 three primary partitions and one
extended partitions Extended partition cannot host an OS file See Table 6-2 on Page 129 for comparison
![Page 7: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/7.jpg)
Dynamic Disks
•A dynamic disk can contain an unlimited number of volumes, but you cannot mark an existing dynamic disk as an active partition▫Simple volume▫Spanned volume▫Striped volume▫Mirrored volume▫RAID-5 volume
![Page 8: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/8.jpg)
Simple and Spanned Volumes•Simple volume
▫Consists of free space contained on a single physical disk (Like a partition)
•Spanned volume▫Made up of free space from multiple physical
disks▫Spanned volumes are not fault-tolerant
If you lose one disk in the volume, you will lose all data contained on all disks
▫Created on 2 to 32 disks
![Page 9: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/9.jpg)
Striped Volume•Made up of free space from multiple disks•Uses RAID-0 striping to interleave the data
across the disks▫Improves the read performance of the volume▫Striped volumes are also not fault-tolerant▫Will not withstand the loss of a disk in the
volume•A striped volume can be created on a
minimum of 2 disks and a maximum of 32 disks
![Page 10: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/10.jpg)
Mirrored Volume
•Fault-tolerant volume consisting of two physical disks, in which the data on one disk is copied exactly onto the second disk
•This provides data redundancy▫If one disk in the mirror fails, the other disk
will continue to function without loss of data
![Page 11: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/11.jpg)
RAID-5 volume•A fault-tolerant volume where data is
interleaved across three or more disks much in the same way as in a striped volume
•Has additional information known as parity▫If one disk in a RAID-5 volume fails, the data
can be rebuilt using the parity information stored on the disks in the rest of the volume
•A RAID-5 volume can be created using a minimum of three disks and a maximum of 32 disks
![Page 12: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/12.jpg)
File Sharing
•On most enterprise networks, the principle of “least privilege” should apply▫Users should have only the privileges they
need to perform their required tasks and no more
![Page 13: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/13.jpg)
Permissions
•Privileges granted to specific system entities enabling them to perform a task or access a resource▫Share permissions
By default, the Everyone receives the Allow Read
▫NTFS permissions▫Registry Permissions▫Active Directory permissions
![Page 14: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/14.jpg)
File Services Role•The File Services role
▫Distributed File System (DFS)▫A service that allows you to simplify the
view of file shares located across multiple servers as they appear to your user base
▫Other useful technologies for implementing file sharing on a Windows Server 2008 network
▫See Table 6-4 on Page 139 for components of File Services Role
![Page 15: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/15.jpg)
Distributed File System (DFS)• Includes two technologies:
▫DFS Namespaces▫DFS Replication
• Enable administrators to do the following:▫Simplify the process of locating files▫Control the amount of traffic passing over WAN
links▫Provide users at remote sites with local file server
access▫Configure the network to survive a WAN link failure▫Facilitate consistent backups
![Page 16: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/16.jpg)
DFS Namespace•A collection of references to the actual folder•Display all the shared folders on different
server to the user as one directory or location•See Figure 6-8 on Page 142•Windows Server 2008 and Windows Server
2003 can function as DFS namespace servers▫The Standard Edition and Web Edition products
can host only a single DFS namespace▫The Enterprise Edition and Datacenter Edition
versions can host multiple namespaces
![Page 17: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/17.jpg)
DFS Namespace (Cont.)
•The DFS Namespaces role service supports:▫Stand-alone▫Domain-based
Windows Server 2008 mode Windows 2000 mode
Based on the domain functional level of the domain hosting the namespace
![Page 18: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/18.jpg)
DFS Replication• DFS Replication is a multiple master replication
engine• For multiple shared folders, you must create a
replication group, which is a collection of servers, members, each of which contains a target for a particular DFS folder▫A folder with two targets requires a replication
group with two members: two servers hosting the shared folder
▫At regular intervals, the DFS Replication engine on the namespace server triggers replication events between the two members, using the RDC protocol, so that their target folders remain synchronized.
![Page 19: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/19.jpg)
DFS Replication (Cont.)• By default, replication groups use a full mesh
topology• On a larger installations, hub/spoke topology is
a better way to reduce the traffic▫See Figure 6-11 on Page 149
• With Server 2008 R2, DFS supports read-only DFS replica▫A complete copy of the content folder from the
corporate office is replicated to the branch offices▫To protect data from unauthorized modifications
at the branch office locations
![Page 20: CN2140 Server II (V2) Kemtis Kunanuraksapong MSIS with Distinction MCT, MCITP, MCTS, MCDST, MCP, A+](https://reader036.fdocuments.in/reader036/viewer/2022062417/5517a5fa5503460e6e8b5f28/html5/thumbnails/20.jpg)
Branch Cache
•Branch cache can operate in one of two modes:▫Hosted cache mode▫Distributed cache mode
•Create a WAN accelerator where information is cached on branch computers ▫BranchCache supports IPv4, IPv6, and end-
to-end encryption methods such as SSL and Ipsec
