Introduction:
This is NOT a home user distribution & is intended solely as the base
for our high end server software. No GUI's, No X, No fancy shit. Just
pure Linux!
Features:
o LVM (Logical Volume Manager) featuring...
- Combining of disk drives into physical volumes (called a PV)
- Combining of PV's into volume groups (called VG's), which you
could think of as being the basic storage pool.
- Combining of VG's into physical extents (called PE's)
- Some or all PE's of this VG can be allocated into a logical
volume (called an LV) or LV's in units called logical extents
(called LE's). Each LE is mapped to a corrosponding PE. LE's
and PE's are equal in size. So in the end LG's are nothing but
a normal partition with hundreds, even thousands of more
features & options.
o Highly scalable SGI XFS filesystem featuring...
- Journaling: Quick Recovery
The XFS journaling technology allows it to restart very quickly
after an unexpected interruption, regardless of the number of
files it is managing. Traditional filesystems must do special
filesystem checks after an interruption, which can take many hours
to complete. The XFS journaling avoids these lengthy filesystem
checks.
- Fast Transactions
The XFS filesystem provides the advantages of journaling while
minimizing the performance impact of journaling on read and write
data transactions. Its journaling structures and algorithms are
tuned to log the transactions rapidly. XFS uses efficient table
structures for fast searches and rapid space allocation. XFS
continues to deliver rapid response times, even for directories
with tens of thousands of entries.
- High Scalability
XFS is a full 64-bit filesystem, and thus, as a filesystem, is
capable of handling files as large as a million terabytes.
2
63 = 9 x 1018 = 9 exabytes
In future, as the filesystem size limitations of Linux are
eliminated XFS will scale to the largest filesystems. A million
terabytes is about a million times larger than most large
filesystems in use today. This may seem to be an extremely large
address space, but it is needed to plan for the exponential
disk-density improvements observed in the disk industry in recent
years. As the disk sizes grow, not only does the address space
need to be sufficiently large, but the structures and algorithms
need to scale. XFS is ready today with the technologies needed for
this scalability.
- Excellent Bandwidth
XFS as a filesystem is capable of delivering near-raw I/O
performance. XFS has proven scalability on SGI MIPS systems of
multiple gigabytes/sec on multiple terabyte filesystems. As the
bandwidth capabilities of Linux improve, the XFS filesystem will
be able to utilize those capabilities.
- A few more things supported...
POSIX Access Control Lists (ACLs), Extended Attributes, User & Group
Quotas, Full NFS v3 Compatibility, Backup/Restore, Hierarchical
Storage Implemented With The Data Management API (DMAPI), Swap To
Files.

- JFS
- Msdos
- Nfs v4
- Ramfs
- Reiserfs
- Smbfs
- UDF
- UFS
- Umsdos
- Vfat
- Devfs
o Support for up to 64Gb RAM
o Support for up to 64 processor systems
o Full ISA Plug & Play support
o Services Supported...
- Apache (Webserver)
Apache has been the most popular web server on the Internet
since April of 1996. The September 2001 Netcraft Web Server
Survey found that 59% of the web sites on the Internet are
using Apache (around 60% if Apache derivatives are included),
thus making it more widely used than all other web servers
combined.
- ISC BIND (Domain Name Server)
With DNS Security with DNSSEC (signed zones) and TSIG (signed
zone requests), DNS protocol enhancements IXFR, DDNS, Notify,
EDNS0 & improved standards conformance. Views are also
supported where one server process can have multiple "views" of
the DNS namespace. eg. "inside" view to internal clients and
"outside" view to outside clients. Enhanced multiprocessor
support.
- PostgreSQL (Database Server)
PostgreSQL is a sophisticated Object-Relational DBMS,
supporting almost all SQL constructs, including subselects,
transactions, and user-defined types and functions. It is the
most advanced open-source database available anywhere.
- ProFTPD (FTP Server)
ProFTPD grew out of the desire to have a secure and configurable
FTP server, and out of a significant admiration of the Apache web
server. There are currently a very limited number of FTP servers
running on Unix (or Unix-like) hosts. The most commonly used
server is wu-ftpd. While wu-ftpd provides excellent performance
and is generally a good product, it lacks numerous features found
in newer Win32 FTP servers and has a poor security history. Many
people, including the developers who work on ProFTPD, have spent
a great deal of time fixing bugs and hacking features into
wu-ftpd. Unfortunately, it quickly became clear that a complete
redesign was necessary in order to implement the configurability
and features desired. ProFTPD is not a hack based on any other
server, it's an independent source tree from the ground up. A
number of well known and high traffic sites use ProFTPD.
- Sendmail (Mail Transfer Agent)
[soo much power, soo many features, impossible to summarize]
System requirements:
o i586 (Pentium) or better
o 32Mb RAM or more (more services running = more RAM required)
o 1Gb Hdd space
