English to Chinese Tech/Engineering Computers: Systems, Networks

"When I first started covering grids two and a half years ago, Sun had defined grids as including clusters," says Joe Clabby, president of technology research company Clabby Analytics and author of a recent report on the state of grid. By that definition, Sun would have had more than 5,000 grids. But while grids and clustering both share resources across multiple machines, grids, according to Clabby, are different because they allow "distributed resource management of heterogeneous systems." In other words, with grids you can quickly add and subtract systems—without regard for location, operating system or normal purpose—as needs dictate. Clusters are built from the ground up to function as a single pool of compute power and consequently aren't as flexible.
