Release Info
Extra extra, storage is cheap, storage is cheap. Spread the not-so-new 'news.' As such, we think horizontal scaling and management of commodity storage in-lieu of vertical, limited scaling. File systems and Volume managers have been extended and commoditized to handle rather inexpensivly, massive scales of storage. LVM and ZFS are examples of Volume Management frameworks that offer extremely scalable options once the domain of proprietary solutions. Spend some time on LVM and ZFS.Release Syllabus
