130 OES 2 SP3: Planning and Implementation Guide
The XFS file system is open source and is included in major Linux distributions. It originated from
SGI (Irix) and was designed specifically for large files and large volume scalability.
Video and multimedia files are best handled by this file system. Scaling to petabyte volumes, it also
handles very large amounts of data. It is one of the few file systems on Linux that supports HSM
data migration.
File Access Protocol Support
OES 2 offers support for a variety of file access protocols.

AFP: The Apple Filing Protocol (AFP) is a network protocol that offers file services for Mac
OS X and the original Mac OS.

CIFS (Novell CIFS and Samba): The Common Internet File Services (CIFS) protocol is the
protocol for Windows networking and file services.
Novell CIFS is a ported version of the CIFS file service traditionally available only on NetWare
but now available for OES 2.
Samba is an open source software version of CIFS based on extensive use and analysis of the
wire protocol of Microsoft Windows machines.

FTP: The File Transfer Protocol (FTP) is one of the most common and widely used simple
protocols in the Internet. Virtually all platforms and devices support FTP at some level, but it is
a very simple protocol, only allowing for uploading and downloading of files.

HTTP: The Hypertext Transfer Protocol (HTTP) is the dominant protocol on the World Wide
Web today, and is the one “spoken” by Web browser clients and Web servers. It is like FTP in
being designed strictly for transfers of HTML (Hypertext Markup Language) and additional
markup languages that have been invented, such as XML (Extensible Markup Language).

NCP: The NetWare Core Protocol (NCP) is the client server protocol developed by Novell for
supporting DOS, Windows, OS/2, Macintosh, UNIX (UnixWare), and Linux for shared file
services.
The NCP Server on Linux includes emulation for the Novell Trustee Model and inheritance
plus visibility when it runs on traditional POSIX file systems such as Ext3, Reiser, and XFS.
When it runs on NSS on Linux, these capabilities are synchronized with the NSS File system
and its extended directory and file attributes, such as Rename Inhibit.
OES 2 Workloads
Each file system has its strengths and weaknesses depending on the workload the file system
supports. This section gives some guidelines for picking and building the right file system for a
given workload. In determining which file system to use for a particular workload, consider your
environment and the following explanation of each workload to determine which file system best
meets your workload environment.
