Levanta Releases MapFS Code To Open Source Community

    SAN MATEO, Calif., Oct. 31 /PRNewswire/ -- Levanta, the leader in Linux
 management, today announced that the company has released its MapFS code to
 the open source community.  MapFS -- a key component in Levanta's
 award-winning Linux management appliance -- is a virtual file system that
 simplifies data sharing between multiple Linux machines connected to a shared
 storage medium (SAN/NAS/Mainframe DASD).
     As a Linux kernel-loadable module, MapFS has been developed under the GPL
 since its incarnation in early 2004.  MapFS is now being made widely available
 to the Open Source community via SourceForge, at
 http://sourceforge.net/projects/mapfs, and on Levanta's web site, at
     "Linux management is one of the hottest development areas in Open Source
 today," said Matt Mosman, CEO of Levanta.  "By nature, Linux is extremely
 well-suited for advanced techniques in server provisioning, disaster recovery,
 change management and other common systems management scenarios where,
 frankly, Windows management solutions have been relatively stagnant.  Linux is
 where the management innovation is happening today, and by releasing MapFS,
 Levanta is introducing a mature, free code base that introduces interesting
 new virtualization techniques that we believe the development community will
 find compelling."
     MapFS implements a Linux filesystem which utilizes copy-on-write
 functionality and existing Linux filesystems to allow component filesystems
 (or portions thereof) to be combined into a single virtual filesystem that
 appears to be fully writable.  MapFS is written in C and uses the standard
 Linux kernel VFS and loadable module interfaces for defining new filesystem
 types to the kernel.  MapFS supports major kernel versions, including 2.4.7 >
     With MapFS, a Linux system can provide sharing of read-only file systems
 while at the same time providing each client of the read-only file system the
 ability to write to its own data store.  Files can be either on a read-only
 persistent repository file system, or on a writable persistent overlay file
 system.  This enables an "optimistic sharing," where everything on the file
 system is assumed to be read-only.  If an attempt is made to modify a
 file -- that is, a private copy is needed -- the performance hit is typically
 minimal, because most written-to files are small.  Even in the event of a
 larger file, the performance hit is a one-time cost.
