Publisher's Description:
AFS is a distributed filesystem product, pioneered at Carnegie Mellon University and supported and developed as a product by Transarc Corporation (now IBM Pittsburgh Labs). It offers a client-server architecture for federated file sharing and replicated read-only content distribution, providing location independence, scalability, security, and transparent migration capabilities. AFS is available for a broad range of heterogeneous systems including UNIX, Linux, MacOS X, and Microsoft Windows.

IBM branched the source of the AFS product, and made a copy of the source available for community development and maintenance. They called the release OpenAFS.

For Windows Users:

OpenAFS is the world's foremost location independent file system. With OpenAFS for Windows, users of Microsoft Windows 2000, XP, 2003, XP64, Vista (32-bit and 64-bit editions) and Server 2008 (32-bit and 64-bit editions) can make the most of this proven data sharing solution. The OpenAFS Project provides binary installation packages appropriate for both individual users and organizations with thousands of members.

How to Decide Which Version to Install:

The following guidelines should be used for choosing an installer type. If you are upgrading from a previous installation, select the same type of installer, EXE or MSI, as was previously installed on the system. If you are installing for the first time, choose the EXE if you are installing manually and the MSI if you either need to customize the installation package (via a transform) or wish to deploy via Active Directory Group Policy.

Each installer is provided in debug and non-debug versions. The debug versions should be installed only when you are experiencing a problem and you need to assist the OpenAFS developers in debugging the problem. The non-debug version is optimized for performance, does not generate logging information by default, and does not install symbol files.

Features:

• Starting with the 1.5.50 release of OpenAFS for Windows, each of the AFS Client Service, the AFS Explorer Shell Extension, and the command-line tools are Unicode enabled. No longer is OpenAFS restricted to accessing file system objects whose names can be represented in the locale specific OEM code page. This has significant benefits for end users. Most importantly it permits non-Western languages to now be used for file system object names in AFS from Microsoft Windows operating systems. Now that Unicode names are supported, Roaming User Profiles and Folder Redirection will no longer fail when a user attempts to store an object with a name that cannot be represented in the OEM code page.

• Support for 64-bit File Sizes on both 32-bit and 64-bit versions of Microsoft Windows
• Support for 64-bit Windows XP/2003/R2/Vista
• Implements Windows Byte Range Locking backed by AFS File Server Locks
• Implements Inline Bulk Status RPCs which speeds up directory listings
• Uses GetCapabilities RPCs to probe the server status
• Logs fs crypt state to the Windows Event Log
• Supports OutputDebugString debugging of the RX Library
• New command: fs uuid [-generate]
• Improved CIFS protocol compatibility
• Hard Dead and Connection Timeout values restricted to the CIFS Session Timeout value.
• Improved handling of Windows Standby/Hibernate modes when network access is not available
• Significant performance improvements when searching directories containing hundreds or thousands of files and sub-directories
• Reduced time required for file open operations
• Fixes a write data corruption error that exists in all versions of OpenAFS prior to 1.5.15
• Increased cache hit ratio for data written to AFS by the local client
• Eliminates "out of volumes" and "out of buffers" panic conditions
• Improved behavior when used from behind Network Address Translation (NAT) devices
• As of 1.5.18, OpenAFS for Windows no longer attempts to push Kerberos v5 tickets into the logon session. This functionality is available in MIT Kerberos for Windows 3.1 and above.
• Fixes a bug that could result in a failure of Microsoft Windows to boot successfully. See Security Advisory OPENAFS-SA-2007-002
• Improved Explorer Shell behavior when viewing directories without "read" permission.
• Lower CPU utilization and overall performance improvements than 1.5.20 and earlier
• The AFS Server Manager no longer terminates unexpectedly
• Infinite recursions in chains of directory objects up to 512 levels deep are detected and prevented.
• Data that is known to be valid will continue to be served by the cache manager when all servers are down.
• Improved directory search performance when compared to 1.5.21 and earlier. Especially after directory updates and when searching for files that do not exist.
• Partial chunks are written to the file server whenever possible improving write performance.
• Default chunk size increased to 1MB from 128KB as of 1.5.23 improving read and write performance.
• The 1.5.31 release fixes a bug that would prevent failover when a volume cannot be attached by a single file server instance.
• The 1.5.32 more than doubles the throughput of both reads and writes when compared to previous releases. One 1Gbit/second networks peak transfer rates of up to 32MB/second have been recorded between the cache manager and the file server.
• The 1.5.39 release fixes several memory leaks.
• The 1.5.51 and 1.5.52 releases fixes bugs introduced in 1.5.50 related to the fs and symlink commands; large file support; smb virtual circuit cleanup operations; and Windows 2000 support.
• The 1.5.53 release fixes significant rx packet leaks dating back to IBM AFS.
