  13. Core Windows Vista Enhancements In Storage Extras Not Covered in Other Sessions!

  14. Core Windows Vista Enhancements In Storage • NTFS • Transactions • Self Healing • Symbolic Links • Backup/Restore • Large sector support

  15. Transactional Enhancements In NTFS • Transactional NTFS (TxF) • Transact to any file systemoperation or set of operations • Full Atomic, Isolated, Consistent,Durable semantics supported • Coordinate work with • Single or Multiple Files • Across multiple volumes • Remote file systems (in server) • Registry (now transacted) • SQL Server, MSMQ, etc.

  16. Transactional Enhancements In NTFS • Common Log File System • High performance, robust, multi-stream,logging subsystem • Support simple logging or complextransactional logging • Filter Manager • Provides transactional framework for mini-filters • Easily write filters which participate in transactions • Kernel Transaction Manager • Write your own transactional resource in the kernel or user mode • Legacy filters can use KTM to participate in a transaction

  17. Using Kernel Transactions • Nt: Zw/NtCreateTransaction(…) • Win32: CreateTransaction() • Kernel Mode • IoCreateFile() • ExtraCreateParameters specifies transaction handle • User Mode • SetCurrentTransaction() sets transaction in the TEB • Create/Delete/Update etc. picks up the current transaction and creates a transacted file handle

  18. Self-Healing In NTFS • What? • Think Chkdsk on the fly • Detection and repair file system corruptionsnon-intrusive and non-disruptive to the userin most cases • Why? • Increase file system availability • Improvements • Dedicated Self-healing worker thread triggeredby detection of corruption • Only Corrupted files/folder inaccessible during repairsunlike lock of the entire volume • Allow authorized users to administer and monitor repair operations. Initiating on-disk verification, waitingon completion of repair and receiving progress status

  19. Symbolic Links In NTFS • What? • Redirection mechanism –the target file or directorycan be local as well as remote • Why? • Enables migrations fromUnix environments to Windows • Provides a platform primitivefor transparent redirectionof files or directories

  20. Symbolic Links In NTFS Features • A symbolic link is always evaluatedby the originating machine • Remote file/directory target using UNCpath names • Symbolic links to directories will havethe “directory bit” set • Registry keys to enable/disable evaluation of symlinkson granular level ( Local->Local, Local->Remote etc.) • A special privilege is required to create symlinks,granted only to elevated administrators by default • Only available on Windows Vista and future OS’es • Only a NTFS feature

  21. Backup/Restore Enhancements Completely new features • Based on volume shadow copy technology • New support for optical media Windows Vista • Simple UI, targeted at consumers • File backup and block-level system backup Windows Server codenamed “Longhorn” • Focused on single-server backup • Same block-level engine as client backup • Restore disks, files, and databases Note: No inbox tape application (OS still tape-compatible)

  22. Large-Sector Drives • HDD manufacturers are movingto drives with larger sector sizes • Traditionally, sectors have been512 bytes in size • New drives may have 1 K, 2 K, or 4 K sectors • For backward compatibility,some drives will be mixed • 512 byte logical sectors with 4 K physical sectors • Necessary to continue making stridesin size, performance and reliability

  23. Windows Vista SupportFor Large-Sector Drives • Windows Vista’s storage stackwill support large-sector drives • IOCTL_STORAGE_QUERY_PROPERTYwill return both logical and physical sector sizes • Applications may still need modification • Use the IOCTL to determinephysical sector size • A physical sector will be the unit of atomic write • Especially important for database-style apps

  24. Call To Action • Understand, support, and takeadvantage of storage enhancements coming in Windows Vista • Look for synergy between your future plans for storage device product and feature development and Microsoft’skey pillars for investment • Use the guidance presentedhere to optimize yourattendance at WinHEC 2006!
