Update of /cvsroot/devil-linux/build/scripts/configuration/help
In directory fdv4jf1.ch3.sourceforge.com:/tmp/cvs-serv20047/configuration/help
- added 2 full-featured network system: the first is network block device and
the second one is parallel network fs (a-la pNFS)
--- NEW FILE: pohmefs.help ---
POHMELFS stands for Parallel Optimized Host Message
Exchange Layered File System.
POHMELFS is a kernel client for the developed distributed
parallel internet filesystem. As it exists today, it is a
high-performance parallel network filesystem with ability
to balance reading from multiple hosts and simultaneously
write data to multiple hosts.
Main design goal of this filesystem is to implement very
fast and scalable network filesystem with local writeback
cache of data and metadata, which greatly speeds up every
IO operation compared to traditional writethrough based
Read balancing and writing to multiple hosts features can
be used to improve parallel multithreaded read-mostly data
processing workload and organize fault-tolerant systems.
POHMELFS as a network client does not support data
synchrnonization between the nodes, so this task should be
implemented in servers. POHMELFS and multiple-server-write
can be used as backup solution for the physically
distributed network servers.
--- NEW FILE: dst.help ---
DST is a network block device storage, which can be used to organize
exported storages on the remote nodes into the local block device.
It's an analog of NBD, AoE and iSCSI network block device implementation
