Small and medium-sized enterprises with no full-time IT staff are beginning to get some of the same features that large data centers have for efficiency and control. A new operating system for storage gear from LenovoEMC will add features such as snapshot capability, automated caching and server virtualization. The OS, called LifeLine 4.0, will be available as a free download next week for users of the company's ix and px systems and should start shipping in products next month, according to LenovoEMC.
