Enhancements In Storage
Extras Not Covered in Other Sessions!
Core Windows Vista
Enhancements In Storage
NTFS
Transactions
Self Healing
Symbolic Links
Backup/Restore
Large sector support
Transactional Enhancements In NTFS
Transactional NTFS (TxF)
Transact to any file system
operation 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.
Transactional
Enhancements In NTFS
Common Log File System
High performance, robust, multi-stream,
logging subsystem
Support simple logging or complex
transactional 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
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
Self-Healing In NTFS
What?
Think Chkdsk on the fly
Detection and repair file system corruptions
non-intrusive and non-disruptive to the user
in most cases
Why?
Increase file system availability
Improvements
Dedicated Self-healing worker thread triggered
by detection of corruption
Only Corrupted files/folder inaccessible during repairs
unlike lock of the entire volume
Allow authorized users to administer and monitor repair
operations. Initiating on-disk verification, waiting
on completion of repair and receiving progress status
Symbolic Links In NTFS
What?
Redirection mechanism –
the target file or directory
can be local as well as remote
Why?
Enables migrations from
Unix environments to Windows
Provides a platform primitive
for transparent redirection
of files or directories
Symbolic Links In NTFS
Features
A symbolic link is always evaluated
by the originating machine
Remote file/directory target using UNC
path names
Symbolic links to directories will have
the “directory bit” set
Registry keys to enable/disable evaluation of symlinks
on 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
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)
Large-Sector Drives
HDD manufacturers are moving
to drives with larger sector sizes
Traditionally, sectors have been
512 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 strides
in size, performance and reliability
Windows Vista Support
For Large-Sector Drives
Windows Vista’s storage stack
will support large-sector drives
IOCTL_STORAGE_QUERY_PROPERTY
will return both logical and physical sector sizes
Applications may still need modification
Use the IOCTL to determine
physical sector size
A physical sector will be the unit of atomic write
Especially important for database-style apps
Call To Action
Understand, support, and take
advantage of storage enhancements
coming in Windows Vista
Look for synergy between your future
plans for storage device product and
feature development and Microsoft’s
key pillars for investment

here to optimize your
attendance at WinHEC 2006!
