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. o Support for the following filesystems - XFS (Primary) - Coda - Ext2/3fs - 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 Download version 2.2.8 from: Sourceforge Mailing lists: o Technical Questions / Discussions Post to : firstname.lastname@example.org Subscribe: here NOTE: This is NOT a home user distribution & newbie questions will only be wasting everyone's time.
