The modulardesign of the DMX Architecture

can be tailored to provide front- and back-

end configurations to meet specific host

requirements and application

performance.

Targeted configurations with additional

front-end directorscan be optimized to

support high server counts in large storage

consolidation initiatives.

Chapter Five: Symmetrix DMX Functionality

In the course of the past decade, Symmetrix systems have proven to be the most capable stor-

age system ever built. With the introduction of the Direct Matrix Architecture, Symmetrix func-

tionality rises to a level never before seen in any high-end storage solution
