  1. File System Managementand Fault Tolerance

  2. Contents • Windows Server 2008 R2 Disks • Utilizing External Disk Subsystems • Managing Windows Server 2008 R2 Disks • System File Reliability • Adding the File Services Role • Managing Data Access Using Windows Server 2008 R2 Shares • Volume-Based NTFS Quota Management • File Server Resource Manager (FSRM) • Distributed File System • Planning a DFS Deployment • Installing DFS • Managing and Troubleshooting DFS • Backing Up DFS • Using Volume Shadow Copy Service

  3. File System Management Tools

  4. Concepts • GUID Partition Table (GPT) Disk • Dynamic Disk • extend Windows disk functionality when managing multiple disks

  5. Concepts- basic disk • supports only simple volumes • OR volumes that exist on a single disk &partition within Windows. • contain no fault tolerance

  6. Concepts- dynamic disk • extend Windows disk functionality when managing multiple disks • host volumes that span multiple partitions and disks within a single system. • Build fault-tolerant & RAID

  7. Managing Windows Server 2008 R2 Disks • Disk Management MMC Snap-In • Diskpart.exe Command-Line Utility

  8. Adding a New Disk to Windows

  9. Converting Basic Disks to Dynamic Disks

  10. Creating Fault-Tolerant Volumes

  11. Creating a Fault-Tolerant Volume Using Diskpart.exe

  12. Adding File Services Role

  13. Managing Data Access Using Windows Server share

  14. Managing Folder Shares • Share and Storage Management console located in Server Manager

  15. Volume-Based NTFS Quota Manage

  16. File Server Resource Manager (FSRM) • Setting limits on storage • Providing storage limit flexibility of group data • Enforcing storage policy • File screen policy • File classification

  17. Installing FSRM Tools

  18. Config Quotas with File Server Resource Manager

  19. Create a Quota Template

  20. Distributed File System • Data redundancy • Automated data replication • Distributed data consolidation

  21. DFS Namespaces • namespace allows connections to automatically be redirected to different servers without user knowledge • Example • a client connects to the domain DFS namespace \\Companyabc.com\Apps, • client will be redirected to \\Server10\Apps,  client will be unaware of this redirection

  22. DFS-compatible clients

  23. Planning a DFS Deployment • Configuring File Share and NTFS Permissions for DFS Root & Folder Targets • Choosing a DFS Type • Standalone DFS Namespace • name of server that hosts the root target and the share. • Domain-Based DFS Namespace • Windows 2008 Mode for Domain-based DFS Namespace

  24. Planning a DFS Deployment • Planning for DFS Replication • Initial Master • Staging Folder

  25. Installing DFS • Need • DFS role services are selected • “Adding File Services Role” • Select Role Services page, select Distributed File System, DFS Namespaces, and DFS Replication

  26. Create DFS Namespace &Root

  27. Add Additional Namespace Server to Domain-Based Namespace

  28. Create a DFS Folder and Replication Group

  29. ensure that replication occurs as expected • Start with empty DFS namespace folders & targets to keep from having to replicate any data at root level • Do not replicate data between DFS namespace shares • Back up at least 1 DFS folder target and config backup to not update archive bit • Thoroughly test server OS antivirus progs to ensure that no adverse effects are caused by scanning of files on a replicated DFS target. • Verify that drive that will contain staging folder for a replication connection contains ample space to accept amount of replicated data sent and received by server.

  30. Config DFS Read-Only Replication • In Replicate Folder Wizard: select No Topology option button on Topology Selection page. • select replication group in tree pane • in tasks pane select Memberships tab • Right-click desired Replicated Folder member & select Make Readonly
