 Compression on the Sun Storage 7000

Always interesting to read about zfs.

"With ZFS, compression is built directly into the I/O pipeline. When compression is enabled on a dataset (filesystem or LUN), data is compressed just before being sent to the spindles and decompressed as it's read back. Since this happens in the kernel, it's completely transparent to userland applications, which need not be modified at all. Besides the initial configuration (which we'll see in a moment is rather trivial), users need not do anything to take advantage of the space savings offered by compression. "
