Lowering Network Traffic, Reducing Server Load and Saving Disk Space
ShaoLin CogoFS (Cogo FileSystem) is a high-performance and reliable stackable
kernel-based compressed filesystem for Linux. It works transparently on top of all common filesystems and even
network-based filesystems. ShaoLin CogoFS compresses files and stores them in compressed form to multiply
your hard disk space, increases I/O access speed, and reduces network traffic.
Utilize CPU speed to gain ultra performance
ShaoLin CogoFS is designed for high performance, reliability, and easy migration.
It also fills in the gaps for Linux, where there is no known stable compressed filesystems.
Previous systems that performed compression and decompression with slow CPUs on virtual-volume compressed
filesystems may have been slow and unreliable. ShaoLin CogoFS does not use virtual volumes, it presents
compressed files in your existing filesystems as normal files. Corruption risk is minimal because
compression is done on individual files. As we know the speed of CPU has dramatically increased in the
pass few years, decompression speeds can easily outperform most uncompressed disks transfer speeds
with today's fast CPUs; because the compressed filesystem will significantly reduce actual data
transfer to and from the physically-slow hard disk media.
Speeding up your network with lower cost
ShaoLin CogoFS differs from other block level compressed filesystems, such as
DoubleSpace, Stacker, and NTFS; it does not manage disk blocks. ShaoLin CogoFS works transparently on top
of all common filesystems and even network-based filesystems, like NFS. More important than just saving
disk space, ShaoLin CogoFS works over the network, transferring compressed files to the CogoFS on the
client to decompress, so the file server does not experience additional processing load. This reduces
network traffic, increases the capacity of the file server's disk, improves disk bandwidth and reduces the
file server load (less data to transfer). The file server will have more cache hits due to more data
fitting into the cache. This innovative design benefits all network-based file access and transfers.
Migration free compression technology
ShaoLin CogoFS achieves the same high compression rates as other compression tools
like ZIP. The files compressed by ShaoLin CogoFS can mix with the uncompressed files so no migration time
is needed. The compression conversion process is done online without rebooting the machine. Ideal to
upgrade your server with no extra migration work.
