Implementing Fault Tolerance by Using RAID Implementing Fault Tolerance by Using RAID RAID Implementations Mirrored Volumes RAID-5 Volumes Implementing Fault-Tolerant Volumes

RAID Implementations Software Implementation (Supported by Windows 2000 Server) RAID 0: Striped Volumes RAID 1: Mirrored volumes RAID 5: Striped volumes with parity Hardware Implementation Disk controller interface handles the creation and regeneration of redundant information RAID level dependent on hardware manufacturer

Mirrored Volumes Mirrored volumes use Ftdisk.sys to simultaneously write data to two volumes on two physical disks. Mirrored Volume Disk 0Disk 1 C: C:Ftdisk.sysFtdisk.sys Fault Tolerance Driver Fault Tolerance Driver Data

Using Disaster Recovery Tools Using Disaster Recovery Tools Starting a Computer by Using Advanced Startup Options Recovering a Computer by Using the Recovery Console Recovering a Computer by Using Disk Image Process

Starting a Computer by Using Advanced Startup Options Operating System Selection Safe Mode Safe Mode with Networking Safe Mode with Command Prompt Enable Boot Logging Last Known Good Configuration Directory Services Restore Mode Debugging Mode Loads basic devices and drivers Loads safe mode options and networking services and drivers Loads safe mode options but starts a command prompt instead of the graphical user interface Logs the loading and initialization of drivers and services F8 Enable VGA Mode Loads the basic VGA driver Uses the last known good configuration to start the computer Allows Active Directory restoration on domain controllers Enables debugging

Recovering a Computer by Using the Recovery Console Use the Recovery Console to: Start and stop services. Read and write data on a local hard drive. Format hard disks and display hidden system files.
