The four distributors Caldera, Conectiva, SUSE Linux, and Turbolinux are
planning to introduce UnitedLinux, a joint server operating system for
enterprise deployment, in November of this year. The technical specifications
have already been finalized.
"Standards, standards, standards!" The growing popularity of Linux as server
operating system in enterprises has been accompanied by an urgent call for
binding technical agreements. Especially international corporations were
disconcerted about the multiplicity of Linux distributions - and many decided
to postpone their strategic decisions in favor of the Open Source operating
system, regardless of the fact that technical and operational aspects actually
encouraged the use of Linux. No wonder! After all, the fractionalization of
Unix into incompatible derivatives is still vivid in the minds of IT decision
makers.
The UnitedLinux initiative now makes head against a repetition of this
"historical" misdevelopment. UnitedLinux not only adheres to existing Linux
standards such as Linux Standard Base (LSB) and Li18nux (internationalization
and localization), it goes far beyond these least common denominators of the
Linux world by defining an entire server operating system. Accordingly, the
UnitedLinux initiative focuses on the professional segment.
This will prove to be beneficial for all. Software providers will have a
uniform platform to which they can rapidly and efficiently port their
applications. Their expenses for product compatibility checks and
certifications will be reduced considerably. This, in turn, is expected to
contribute to an expanded application portfolio, resulting in an increased
acceptance of Linux in the enterprise segment.
Customers will welcome this development. Furthermore, companies operating at
an international scale will appreciate UnitedLinux as the first truly
"global" Linux which not only supports the European languages, but also
Chinese, Japanese, and Korean - both during the installation and in the
desktop environment. UnitedLinux is also suitable for deployment in
heterogeneous IT infrastructure, providing one server operating system with a
uniform Linux code basis for the 32-bit and 64-bit processors of AMD and Intel
as well as for the zSeries, iSeries, and pSeries machines of IBM.
The schedule until the first release of UnitedLinux has already been
determined. Following an alpha version for initial tests, all interfaces will
be "frozen" in the beta phase as of mid-August; from mid-September until the
first release of version 1.0 in November, the work will only concentrate on
improving the stability. UnitedLinux 2.0 is scheduled for the fourth quarter
of 2003. Although UnitedLinux is developed by a multi-company team, the
operating system as well as additional software solutions and services will be
offered and marketed by the individual UnitedLinux partners using their own
brand names.
UnitedLinux 1.0 will support the File Hierarchy Standard 2.2 which regulates
the uniform order of the system files in the directory structure. The Linux
Standard Base, too, is implemented, ensuring a uniform environment for Linux
applications. For this purpose, the standard defines a directory structure,
standard libraries, the boot process, and the file format of binaries. The LSB
ruling explicitly draws on older standards such as the X11 protocol and the
Posix 1 standard.
Li18nux 1.0 assists application developers in internationalizing their
programs. The peculiar designation derives from the widely used abbreviation
I18N: the letters "i" and "n" of "internationalization" are separated by 18
letters. Additionally, some Linux-independent standards are also adhered to,
such as Extensible Markup Language (XML), Simple Object Access Protocol
(Soap), and Web-Based Enterprise Management (WBEM).
To the extent that the official Linux kernel version 2.4 does not yet contain
certain important functions, the UnitedLinux team will port the existing
implementations and make them available for UnitedLinux 1.0. This includes
Memory Expansion Technology (MXT) for compressing the contents of the main
memory as well as direct I/O and multipath I/O for access to mass storage
media. Furthermore, PCI-X, USB floppy, and USB CD-ROM will be supported.
UnitedLinux will support three file systems with journaling functionality:
Ext3, ReiserFS, and IBM's 64-bit file system JFS. A Logical Volume Manager
(LVM) for managing hard disks will also be provided. Computing centers can
look forward to performance gains through more efficient thread support with
the help of NGPT (Next Generation Posix Threads), faster and more
resource-friendly access to hard disks through asynchronous I/O and raw I/O as
well as hyper-threading support. Additional central functions for
administering large networks include the support of Storage Area Networks
(SAN), Simple Network Management Protocol (SNMP), and LDAP (Lightweight
Directory Access Protocol v3). Thanks to large memory support, the United
Linux x86 kernel is able to handle up to 64 GB RAM.
The SUSE system assistant YaST2 (Yet another Setup Tool) will be used as
installation and administration tool. By means of the fully automated
installation with YaST2, UnitedLinux enables rational configuration
management in company networks. The installation can be performed from the
CD-ROM, the local hard disk, or by way of the network.
Apart from the operating system basis that was optimized for stability and
security, UnitedLinux comprises all server services relevant in Linux,
allowing the implementation of Internet services like WWW and FTP or proxy,
mail, and news servers. The UnitedLinux standard equipment also includes
proven Internet helpers such as DHCP, Domain Name Service (DNS), and Time
Service (NTP). Moreover, all functionalities for file and print services in
heterogeneous networks (Unix, Windows 9x/NT/2000/XP, Novell Netware, Mac OS)
are included.
In addition to numerous firewall components such as the ipchains packet filter
setting, the extensive range of security assets also provides encryption
mechanisms like GnuPG and Secure Sockets Layer (SSL). UnitedLinux supports
the widely used authentication tools Kerberos 5 and PAM, and can be utilized
for encrypted communication within a Virtual Private Network (VPN). OpenLDAP
is used as directory service. The uniform Linux offers the graphical desktop
environments KDE 3 and Gnome 2.
One of the main tasks of the integration team in the weeks to come consists of
the standardization of the interfaces for the hardware and software providers,
which will also include the installation of new hardware drivers. In order to
facilitate and accelerate porting for application developers, developer
versions of UnitedLinux that comprise compilers, libraries, and developer
tools as well as binaries and the source code of the operating system will be
made available at an early date.
In order to be able to operate their IT infrastructure permanently on the
basis of a secure, powerful, and stable operating system, professional Linux
users depend heavily on the manufacturer's guarantee. The system maintenance
for UnitedLinux vouches for long-term investment security, as the
certifications of leading hardware and software providers retain their
validity even after an update. Within the scope of this system maintenance,
the product integrator SUSE makes all all relevant patches, fixes, and updates
available in a quality-assured and documented form.
