  2. Agenda • Chapter 6: Configuring File Services • Exercise • Lab • Midterm Exam

  3. 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

  4. 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?

  5. 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

  6. 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

  7. 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

  8. 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

  9. 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

  10. 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

  11. 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

  12. 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

  13. 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

  14. 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

  15. 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

  16. 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

  17. 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

  18. 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.

  19. 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

  20. 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

  21. Assignment • Summarize the chapter in your own word • At least 75 words • Due BEFOREclass start on Thursday • Lab 6 • Due BEFORE class start on Monday
